Zooming in a title.

Hi Guys, Just wonderd how I can zoom in a title without the background following the transition too. Say i make a title, it has a black background by default and i want just the text to zoom in using the zoom transition, how do I stop the black background doing it too. Ive tried putting a black layer at a parralell point on a different video track but that doesn't work. Any ideas?
Thanks,
Ed

Say i make a title, it has a black background by default
Actually, a title has NO background, by default. It may appear to be black, depending on where the CTI is located in the timeline. You can toggle the background visibility and select the visible frame using the following controls in the Titler:
If you DO indeed have a black background, you must have drawn a rectangle filled with black--select and delete that so that the title "floats" over whatever background you place it on.
I want just the text to zoom in using the zoom transition, how do I stop the black background doing it too.
Don't use a transition for this manuever; animate Scale properties, instead:
Since the title has an alpha channel (e.g. transparent background), when you animate the scale, only it will move.

Zoom while in title panel?

Using Premiere Pro CS6, when creating a Title -> New Title -> Default Still, how do you zoom in that panel? I'm trying to add a shape and need to zoom in so i can make it the same size as the object on the video screen below, but i don't see any way for me to zoom in. The area where i can add shapes or text appears to just be a percentage of my title panel. No way to zoom in to let's say 800%? Thanks in advance for any help.

hmm, wierd, it seems like it'd be useful, weird that you can't zoom. the Tilde trick helped some but still wish i could zoom in tighter. Thanks for confirming it's not included.

Help with Find / Replace button title tag contents (text)

Hi there,
I designed my site with Sitegrinder (Medialab) –
Currently all the title tags generated for buttons are the same as
the actual html page name.
The problem with this is that the tooltip which appears in
browsers when you hover over the button with the mouse gives you
the page name. Instead I want to use these tooltips to give the
user an indication of what the function of the button is.
An example: A zoom button above an image: Currenty the
tootlip says “zoom imagename pagename” – Instead
it should say “click here to zoom”.
I need help to get the Dreamweaver Find and Replace tool to
batch replace these tags for me for about a 100 pages.
Here is an example of the code:
<body>
<div id="id1zoomimpastooilweddingbutton"><a
href="zoomimpastooilwedding.html"
title="zoomimpastooilwedding"></a></div>
I only want to replace the text in the title tag - Since the
text “zoom” appears several times in the body, I
can’t get the Find tool to pick up and Replace the occurrence
of “zoom” in the title only…….
Options I’ve tried:
Search Current document: Search for: “specific
tag”: “title”, “containing”:
“text” = zoom (I’ve tried this with
“zoomimpastooilwedding” and zoom[^”]* with no
results
I’ve also tried: Search for: “specific
tag”: “body”, “containing”:
“specific tag” “title”
“containing”: “text” = zoom
etc……………..
I need help with what parameters to enter in order to find
and replace all the text within the title tag with my own text
Thanks very much!
Anton

You have ~ 100 pages, each of which has images with title
attributes (not
tags), all of which BEGIN with the letters "zoom"?
What do you want to replace that text with? Wouldn't it be
different for
each button? Or do you mean that you would do multiple
sitewide searches,
one for each button? This illustrates how wrong it is to not
use DW
Templates or server-side includes to simplify the management
of your
navigation elements....
Did you ask Medialabs if it would be possible to specify this
before
generating the HTML?
How did you like working with SiteGrinder? It looks like a
nice product to
me, although I'm not fond of the final results code-wise....

WHY IS IMPORTING FROM CD SUDDENLY SO SLOW??

When I click on the Import CD button at the bottom of the page, the titles are immediately displayed as per usual in the program and each entry is checked. But the importation used to ZOOM through whatever titles were checked. Now everything is in molasses; so slow. I removed quite a few trojans and other malware just this evening using a separate program -- should I reinstall the iTunes program to get back to speed? Any cautions about reinstalling so that I don't lose any of my music? -- I have almost 5,000 songs in my iTunes library.
I have tried to reboot to no avail. I have tried cleaning the CDs to no avail. My CD-ROM would usually finish importing all of the songs from a typical CD in about 3 minutes -- very efficient. Now the progress bar tells me that about 37 minutes remain just for one song!! In addition, once the CD begins to run in the tower, the program freezes -- hangs -- and the only way to get back to my Desktop is to ctrlaltdelete. This N-E-V-E-R happened before, having just started about 2 days ago.
Can someone PLEASE help me? Could this be a virus/worm??
Thanks!

Could you mention why the speeds are different per song?
Speeds are approximate based on how much has converted so far, and how much file is left.
Also, the complexity of the file has a large bearing on conversion time.
So too does the format type of the file, (someone else mentioned this).
Read errors require the pc to check and check again before moving on. This may have been part of your original problem. Sometimes removing the disc and cleaning can make a big difference.
Read speed varies across the disc from the hub to the edge, as the 'table of contents' file located near the hub needs to be cross-referenced regularly to locate the file contents. As the transport of the read head takes time from the centre to the edge, and this process needs to be repeated, it takes a lot longer near the edge to access a file. This is similar with a hard drive that is near full.

Bad image quality of slideshows

I am a new Mac user. I am having difficulty making slideshows from the iLife version 6 software with the features that I want and decent image quality.
I've been trying with iPhoto, iMovieHD and iDVD. I want to be able to put captions or title screens in my slideshows, so I must use either iDVD or iMovieHD. If I do not want my photos to pan and zoom, I can use iDVD. I've done this and burned the result to a DVD. When I play the DVD on my 65" wide screen high definition television, the image quality of the slideshow is not satisfactory. Diagonal lines have visible stepping. Just before a photo transitions to the next photo, there is a noticeable increase in the number of digital artifacts for about one second.
For some slideshows, I wanted to have the pan and zoom effects, and title screens, so I used iMovieHD. When I started the project, I chose the format 1080i because that is what my high definition television can do. I realize, however, that my DVD player cannot do that resolution, so I am not sure that was the correct format to choose. I "shared" the completed slideshow movie to iDVD. When I play that slideshow, I see many digital artifacts in the images as the zoom happens. The images are not as good as looking at the original digital photos on the computer.
Is there a way to make a slideshow on a DVD that has an image quality that matches the original digital photograph? Is it possible to use the pan and zoom effect when I wish to play a DVD slideshow on a television?
Any help is appreciated.
MacBook Pro Mac OS X (10.4.4) 2MB memory, 15"

I realize that I did not ask exactly the right question.
I've made slideshows using U-lead software on my windows XP desktop machine. The image quality of those slideshows on a standard TV is better than what I can do with iDVD and iMovie. So I'm wondering is there something I need to do in iDVD that might be automatically happening in the U-lead software. Obviously, I do not expect people here to know anything about that software, but you might know of something in the iDVD software that will prevent the digital artifacts that I see when I use iDVD to make a slideshow. So far, the slideshows I've made are bordering on not watchable.

Adobe Encore CS4 File is not valid MPEG?

Hi!
Today, I opened up my Encore project to make a small change. I imported new assets and changed the menu to something different and then linked my buttons to a new timeline that then linked to another timeline.
I planned to create a DVD, but while it was transcoding and error popped up that said "Adobe Encore File is not valid MPEG."
All of my assets are in MPEG2-DVD format. The menu (both the original menu and the new one) was a video created in After Effects CS4 and the other assets were created in Premiere Pro CS4.
Both the menu and video are 720x480.
Thanks,
Brittany

Um, I'm not exactly sure how to find this, but I just right clicked on the video to click properties and this is what I found:
Menu:
Data Rate: 6455kbps
Menu Audio Bit Rate: 1536kbps
Second Part of Menu: (I have it set up so that it when you click "Play" or "Behind the Scenes" that it looks like the camera zooms into the title on the menu. This is in a seperate timeline.)
Data Rate: 6000kbps
Audio Bit Rate: 1536kbps
Main Video:
Data Rate: 7000kbps
Audio Bit Rate: 1536kbps
Also, I don't know if this is worth mentioning, but .xmp and .m2v.xmpses files also rendered along with my MPEG2-DVD video. I guess this is standard but I just thought I should mention it.

Flag for overriding TV zoom function? Or title-safe settings for zoomed video...

Here's the problem: I've got SD spots with correctly set up title-safe graphics. However, I keep seeing the spots playing on HD TV's where the picture has been set to zoom/stretch, and consequently the title graphics are stretching off-screen.
So the question's actually a two-parter: Is there a flag I can set in my video that will override an HD set's zoom function and force my spots to play unstretched on these TV's? Or (part two), what graphics boundary settings would I have to use to keep my title graphics on-screen even it the video is zoomed?
Regarding part two, yeah, I could experiment and find out the settings that will work, but I figure someone's run into this before and has an answer, which would save me a bunch of time...
Thanks in advance...

Is there a flag I can set in my video that will override an HD set's zoom function
Thank God, no! It's bad enough that disk authors can take away our right to skip FBI warnings and all the other BS on a DVD before we actually get to the movie.

How to zoom into small text in Title Edit Window?

Ok,
So when I am putting in disclaimer text in the Title edit window, I can't read it. I could if I could zoom into it or at least increase the scaling of the video preview.
Someone else has had to have had this problem. As you can see from the attached image, all the wasted extra space around the video, if I could just zoom in like you can on the preview window I could read it.
How can I zoom into the area I am trying to edit with small text???
Pleas help, anyone???

First of all Reset Current workspace, does not seen to fit the window also I would make the titler a floating window.
You cannot zoom in but you can make it full screen by hitting the 'tilde"(grave) key.
You can also scale up the text, adjust, and scale it down again.

IMovie '09 equivalent "zoom" Title

Hi there,
I'm wanting to make use of some very simple titles for a movie I'm making, and I'm partial to the iMovie '09 "zoom" title, yet I can't seem to find it in FCP. Do I have to create this title myself? Or is it available and I'm simply overlooking it?
Thank you so much,
YahYah

What version of FCP?
If you have FCS 2 or earlier, there's a bunch of pre-built zoom effects in LiveType.
From LT's Browser: Effects > Zooms.
Easy to make your own though, experiment with the Scale controls in FCP's Motion tab or use the Motion application that came with your copy of FCS.

Premier 12, Titles & Text, Current Time indicator, Pan & zoom

I am using Premier 12 and am really enjoying the program, I had been using Premier 8 and I am getting much fewer project crashes, in fact almost none! Whomever worked on this program did a really good job. I am also finding it very user friendly and have been using both the "quick" and the "expert" portions of the program. That said I have three questions,
Titles and text, I am using one with "scrolling credits", is there a function where I can either "freeze" the screen after it scrolls to the text OR is there a function to "replay" the text instead of just going "black" and stopping?
Also when I have added all of my clips onto the timeline and have my "curent time indicator" at the "end" it does not stop and "go back" to the beginning/home unless I manually hit the "home" on my keyboard. I want to make sure that when I go to burn that the movie will instantly go back to the beginning of the project.
Is is possible to do a type of "Ken Burns" panning and zooming with Premier 12 and if so how do you do it?
Thanks

Good to learn of your progress with Premiere Elements 12.
3. Is is possible to do a type of "Ken Burns" panning and zooming with Premier 12 and if so how do you do it?
The Premiere Elements 8.0/8.0.1 Horizontal and Vertical Pan & Zoom choices in Presets are available in version 12 under fx Effects/Presets/. As in 8.0/8.0.1, in 12 it is either pan OR zoom applied to each clip, not pan AND zoom.
As in 8.0/8.0.1, in 12 there is the Motion Panel expanded and its Toggle Animation for doing more advanced pan and zoom effects. Here look to Applied Effects Tab/Applied Effects Palette/Motion Panel expanded for it Scale (for Zoom) and Position (Pan) properties.
The Pan and Zoom Tool is not found in version 8.0/8.0.1. It can be found in 12, Tools Menu/Pan and Zoom. The feature comes with its own workspace once you select the image and then the feature under Tools Menu. Note, when the panned and zoom image is returned to the Premiere Elements workspace from the Pan and Zoom workspace, the duration of the image is markedly increased. That is normal. Here is a sample of more information on the topic

I am not sure that you are dealing with leftover beyond the left gray tab of the Work Area Bar. So let us make sure.
After you have added all your clips to the Timeline, do the gray tabs of the Work Area Bar span that Timeline content from what you see as the beginning and end of the whole content? When you hit the play button of the monitor, does the Timeline content playback from beginning and end of what you can see as the beginning and end or does the Timeline Indicator continue beyond the last item that you put on the Timeline? If the latter, then you are some fragments further to the right of the end that you can see. Typically the present (with Timeline content expanded max) as very thin vertical black lines which will need to be deleted. In these cases, use the End key stop position to search for the leftover(s).
Other Home and End key to navigate the whole Timeline content under the gray tabs of the Work Area Bar.
Titles and text, I am using one with "scrolling credits", is there a function where I can either "freeze" the screen after it scrolls to the text OR is there a function to "replay" the text instead of just going "black" and stopping?
The basics of this feature should be the same as in Premiere Elements 8.0/8.0.1. Menu name is different and Titler has a different look but principles are the same between 8.0/8.0.1 and 12. Are you talking about looping a text title? Sounds like that. If so we can talk about that in greater detail. Have you done in 8.0/8.0.1 what you want to go in 12 in this regard? Or is this a new effect that you want to achieve?
Please review. Keep up the great work.

How do I change the way the title/author appear and is there any way to remove pages on EPUBs?

Hi all--
I am having a really hard time--I am trying to transfer EPUBs from my Win 7 comp to my Nook Tablet. I bought a lot of books from several non-BN sites because they were lots cheaper and were also sold in bundles--but the site was messed up and sent the books in PDF form rather than EPUB. PDF files won't read like a regular book on my Nook Tablet, so my friend offered to convert them to EPUB for me.
Most of the books turned out fine, but some of them now have a few extra pages at the beginning before the cover image and the correct title and author are not displaying--it seems to instead show the filepath where the file was saved on m friend's computer (C:\My Computer/Documents and Settings...etc.)
So, what I would like to do is be able to edit the EPUB files so I can delete the extra pages at the beginning so the correct cover image will be displayed and to be able to change the file's data sp it will show (and be searchable by) the correct title and author.
I am new to all this, so I appreciate any help you can offer. Thank you SO much for your help!!
--Jamie
P.S. Having the title and author show up correctly so they are searchable and appear in the correct place on my Nook Tablet is the top priority--correct cover pages would be nice aesthitically, but it is not that important.
****ALSO--does anyone know of an app or anything for the Nook Tablet that would allow PDF files to be read just like an EPUB/B&N=purchased book? Currently when I open a PDF, it shows the page in TINY print--you can use pinching to zoom in, but then the file enlarges so it is bigger than the screen, making it very hard to read. I can't figure out any way to enlarge the text but still fits the page like an EPUB does, so I'm wondering if there's an app that would do that--it's hard because you can't try apps before you buy them and I can't teel if they will work from the descriptions.

For sideloaded content the nook pulls the metadata from ePub file itself. I would suggest looking at a program like Sigil or Calibre that will let you edit the metadata in the book to make it appear like you want.
For the PDF vs ePub - No, that's the way PDFs work (think of them as graphics, not text), wheres ePubs are Web Pages - so no you can't them to behave exactly alike without converting the files.

I have photos in iphoto that can only be view in minimum zoom but, when I zoom out pics can not be view when clicked on

When i open iphoto and the zoom is near the minimum, I can see all the photos, but when I move it towards the maximum range, the pictures disappear. If I click on them I only see a blank, black screen.
Someone help???

Apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start with Option #3, followed by #4 and then #1 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

CS4 NOT capable of sharp displays at all zoom levels

I must have been asleep, until now, and missed the significance and importance of what follows.
In post #11 here:
http://forums.adobe.com/thread/375478?tstart=30
on 19 March 2009 Chris Cox (Adobe Photoshop Engineer - his title on the old forums) said this, in a discussion regarding sharpness in CS4:
"You can't have perfectly sharp images at all zoom levels.". Unfortunately, my experience with CS4 since its release late last year has repeatedly confirmed the correctness of this statement.
What makes this statement so disturbing is that it contradicts an overwhelming amount of the pre- and post-release promotional advertising of CS4 by Adobe, to the effect that the OpenGL features of CS4 enable it to display sharp images at all zoom levels and magnifications. What is surprising is that this assertion has been picked up and regurgitated in commentary by other, sometimes highly experienced, Ps users (some unconnected with, but also some directly connected with, Adobe). I relied upon these representations when making my decision to purchase the upgrade from CS3 to CS4. In fact, they were my principal reason for upgrading. Without them, I would not have upgraded. Set out in numbered paragraphs 1 to 6 below is a small selection only of this material.
1. Watch the video "Photoshop CS4: Buy or Die" by Deke McClelland (inducted into the Photoshop Hall of Fame, according to his bio) on the new features of CS4 in a pre-release commentary to be found here:
http://fyi.oreilly.com/2008/09/new-dekepod-deke-mcclelland-on.html
Notice what he says about zooming with Open GL: "every zoom level is a bicubically rendered thing of beauty". That, when viewed with the zooming demonstrated, can only be meant to convey that your image will be "sharp" at all zoom levels. I'm sure he believes it too - Deke is someone who is noted for his outspoken criticism of Photoshop when he believes it to be deserved. It would seem that he must not have experimented and tested to the extent that others posting in this forum have done so.
2. Here's another Adobe TV video from Deke McClelland:
http://tv.adobe.com/#vi+f1584v1021
In this video Deke discusses the "super smooth" and "very smooth" zooming of CS4 at all zoom levels achieved through the use of OpenGL. From the context of his comments about zooming to odd zoom levels like 33.33% and 52.37%, it is beyond doubt that Deke's use of the word "smooth" is intended to convey "sharp". At the conclusion of his discussion on this topic he says that, as a result of CS4's "smooth and accurate" as distinct from "choppy" (quoted words are his) rendering of images at odd zoom levels (example given in this instance was 46.67%), "I can actually soft proof sharpening as it will render for my output device".
3. In an article by Philip Andrews at photoshopsupport.com entitled 'What's New In Adobe Photoshop CS4 - Photoshop 11 - An overview of all the new features in Adobe Photoshop CS4',
see: http://www.photoshopsupport.com/photoshop-cs4/what-is-new-in-photoshop-cs4.html
under the heading 'GPU powered display', this text appears :
"Smooth Accurate Pan and Zoom functions – Unlike previous versions where certain magnification values produced less than optimal previews on screen, CS4 always presents your image crisply and accurately. Yes, this is irrespective of zoom and rotation settings and available right up to pixel level (3200%)." Now, it would be a brave soul indeed who might try to argue that "crisply and accurately" means anything other than "sharply", and certainly, not even by the wildest stretch of the imagination, could it be taken to mean "slightly blurry but smooth" - to use the further words of Chris Cox also contained in his post #11 mentioned in the initial link at the beginning of this post.
4. PhotoshopCAFE has several videos on the new features of CS4. One by Chris Smith here:
http://www.photoshopcafe.com/cs4/vid/CS4Video.htm
is entitled 'GPU Viewing Options". In it, Chris says, whilst demonstrating zooming an image of a guitar: "as I zoom out or as I zoom in, notice that it looks sharp at any resolution. It used to be in Photoshop we had to be at 25, 50 , 75 (he's wrong about 75) % to get the nice sharp preview but now it shows in every magnification".
5. Here's another statement about the sharpness of CS4 at odd zoom levels like 33.33%, but inferentially at all zoom levels. It occurs in an Adobe TV video (under the heading 'GPU Accererated Features', starting at 2 min 30 secs into the video) and is made by no less than Bryan O'Neil Hughes, Product Manager on the Photoshop team, found here:
http://tv.adobe.com/#vi+f1556v1686
After demonstrating zooming in and out of a bunch of documents on a desk, commenting about the type in the documents which is readily visible, he says : "everything is nice and clean and sharp".
6. Finally, consider the Ps CS4 pdf Help file itself (both the original released with 11.0 and the revised edition dated 30 March 2009 following upon the release of the 11.0.1 update). Under the heading 'Smoother panning and zooming' on page 5, it has this to say: "Gracefully navigate to any area of an image with smoother panning and zooming. Maintain clarity as you zoom to invididual pixels, and easily edit at the highest magnification with the new Pixel Grid." The use of the word "clarity" can only mean "sharpness" in this context. Additionally, the link towards the top of page 28 of the Help file (topic of Rotate View Tool) takes you to yet another video by Deke McClelland. Remember, this is Adobe itself telling you to watch this video. 5 minutes and 40 seconds into the video he says: "Every single zoom level is fluid and smooth, meaning that Photoshop displays all pixels properly in all views which ensures more accurate still, video and 3D images as well as better painting, text and shapes.". Not much doubt that he is here talking about sharpness.
So, as you may have concluded, I'm pretty upset about this situation. I have participated in another forum (which raised the lack of sharp rendering by CS4 on several occasions) trying to work with Adobe to overcome what I initially thought may have been only a problem with my aging (but nevertheless, just-complying) system or outdated drivers. But that exercise did not result in any sharpness issue fix, nor was one incorporated in the 11.0.1 update to CS4. And in this forum, I now read that quite a few, perhaps even many, others, with systems whose specifications not only match but well and truly exceed the minimum system requirements for OpenGL compliance with CS4, also continue to experience sharpness problems. It's no surprise, of course, given the admission we now have from Chris Cox. It seems that CS4 is incapable of producing the sharp displays at all zoom levels it was alleged to achieve. Furthermore, it is now abundently clear that, with respect to the issue of sharpness, it is irrelevant whether or not your system meets the advertised minimum OpenGL specifications required for CS4, because the OpenGl features of CS4 simply cannot produce the goods. What makes this state of affairs even more galling is that, unlike CS3 and earlier releases of Photoshop, CS4 with OpenGL activated does not even always produce sharp displays at 12.5, 25, and 50% magnifications (as one example only, see posts #4 and #13 in the initial link at the beginning of this post). It is no answer to say, and it is ridiculous to suggest (as some have done in this forum), that one should turn off OpenGL if one wishes to emulate the sharp display of images formerly available.

Thanks, Andrew, for bringing this up. I have seen comments and questions in different forums from several CS4 users who have had doubts about the new OpenGL display functionality and how it affects apparent sharpness at different zoom levels. I think part of the interest/doubt has been created by the over-the-top hype that has been associated with the feature as you documented very well.
I have been curious about it myself and honestly I didn't notice it at first but then as I read people's comments I looked a little closer and there is indeed a difference at different zoom levels. After studying the situation a bit, here are some preliminary conclusions (and I look forward to comments and corrections):
The "old", non-OpenGL way of display was using nearest-neighbor interpolation.
I am using observation to come to this conclusion, using comparison of images down-sampled with nearest-neighbor and comparing them to what I see in PS with OpenGL turned off. They look similar, if not the same.
The "new", OpenGL way of display is using bilinear interpolation.
I am using observation as well as some inference: The PS OpenGL preferences have an option to "force" bilinear interpolation because some graphics cards need to be told to force the use of shaders to perform the required interpolation. This infers that the interpolation is bilinear.
Nothing is truly "accurate" at less than 100%, regardless of the interpolation used.
Thomas Knoll, Jeff Schewe, and others have been telling us that for a long time, particularly as a reason for not showing sharpening at less than 100% in ACR (We still want it though ). It is just the nature of the beast of re-sampling an image from discrete pixels to discrete pixels.
The "rule of thumb" commonly used for the "old", non-OpenGL display method to use 25%, 50%, etc. for "accurate" display was not really accurate.
Those zoom percentages just turned out to be less bad than some of the other percentages and provided a way to achieve a sort of standard for comparing things. Example: "If my output sharpening looks like "this" at 50% then it will look close to "that" in the actual print.
The "new", OpenGL interpolation is certainly different and arguably better than the old interpolation method.
This is mainly because the more sophisticated interpolation prevents drop-outs that occurred from the old nearest-neighbor approach (see my grid samples below). With nearest-neighbor, certain details that fall into "bad" areas of the interpolated image will be eliminated. With bilinear, those details will still be visible but with less sharpness than other details. Accuracy with both the nearest-neighbor and bilinear interpolations will vary with zoom percentage and where the detail falls within the image.
Since the OpenGL interpolation is different, users may need to develop new "rules of thumb" for zoom percentages they prefer when making certain judgements about an image (sharpening, for example).
Note that anything below 100% is still not "accurate", just as it was not "accurate" before.
As Andrew pointed out, the hype around the new OpenGL bilinear interpolation went a little overboard in a few cases and has probably led to some incorrect expectations from users.
The reason that some users seem to notice the sharpness differences with different zooms using OpenGL and some do not (or are not bothered by it) I believe is related to the different ways that users are accustomed to using Photoshop and the resolution/size of their monitors.
Those people who regularly work with images with fine details (pine tree needles, for example) and/or fine/extreme levels of sharpening are going to see the differences more than people who don't. To some extent, I see this similar to people who battle with moire: they are going to have this problem more frequently if they regularly shoot screen doors and people in fine-lined shirts. Resolution of the monitor used may also be a factor. The size of the monitor in itself is not a factor directly but it may influence how the user uses the zoom and that may in turn have an impact on whether they notice the difference in sharpness or not. CRT vs LCD may also play a role in noticeability.
The notion that the new OpenGL/bilinear interpolation is sharp except at integer zoom percentages is incorrect.
I mention this because I have seen at last one thread implying this and an Adobe employee participated who seemed to back it up. I do not believe this is correct. There are some integer zoom percentages that will appear less sharp than others. It doesn't have anything to do with integers - it has to do with the interaction of the interpolation, the size of the detail, and how that detail falls into the new, interpolated pixel grid.
Overall conclusion:
The bilinear interpolation used in the new OpenGL display is better than the old, non-OpenGL nearest-neighbor method but it is not perfect. I suspect actually, that there is no "perfect" way of "accurately" producing discrete pixels at less than 100%. It is just a matter of using more sophisticated interpolation techniques as computer processing power allows and adapting higher-resolution displays as that technology allows. When I think about it, that appears to be just what Adobe is doing.
Some sample comparisons:
I am attaching some sample comparisons of nearest-neighbor and bilinear interpolation. One is of a simple grid made up of 1 pixel wide lines. The other is of an image of a squirrel. You might find them interesting. In particular, check out the following:
Make sure you are viewing the Jpegs at 100%, otherwise you are applying interpolation onto interpolation.
Notice how in the grid, a 50% down-sample using nearest-neighbor produces no grid at all!
Notice how the 66.67% drops out some lines altogether in the nearest-neighbor version and these same lines appear less sharp than others in the bilinear version.
Notice how nearest-neighbor favors sharp edges. It isn't accurate but it's sharp.
On the squirrel image, note how the image is generally more consistent between zooms for the bilinear versions. There are differences in sharpness though at different zoom percentages for bilinear, though. I just didn't include enough samples to show that clearly here. You can see this yourself by comparing results of zooms a few percentages apart.
Well, I hope that was somewhat helpful. Comments and corrections are welcomed.

Zooming an image and scrolling it using a JScrollPane

Hi all, I know this is one of the most common problems in this forum but i cant get any of the replys to work in my code.
The problem:
I create an image with varying pixel colors depending on the value obtained from an AbstractTableModel and display it to the screen.
I then wish to be able to zoom in on the image and make it scrollable as required.
At the minute the scrolling method is working but only when i resize or un-focus and re-focus the JInternalFrame. Ive tried calling revalidate (and various other options) on the JScrollPane within the paintComponents(Graphics g) method but all to no avail.
Has anyone out there any ideas cause this is melting my head!
Heres the code im using (instance is called and added to a JDesktopPane):

Small mistake, the revalidate must be called on the panel not on the jsp.
import java.awt.*;
import java.awt.event.*;

public class UsaZ extends JFrame
     IPanel      panel = new IPanel();

     addWindowListener(new WindowAdapter()
     {     public void windowClosing(WindowEvent ev)
          {     dispose();
               System.exit(0);
     setBackground(Color.lightGray);
     getContentPane().add("Center",jsp);
     setBounds(1,1,400,320);
     setVisible(true);

     Image map;
     double zoom = 1;

     zoom(0);

               zoom(0.04);
