Length of Panorama

In CS3 My friend is limited to about 40" in Vista and about 6+ feet in XP.
lechtmmg

It's still not clear to me...maybe I'm being thickheaded.
Let's see if I can draw some Mo' Bettah' Info out of you (Though I'd've hoped you'd know to offer it up in the first place. :))
You'll need to explain more about the differences between the system that gives 72"+ and the system that is limited to 40"
Same hardware config? Same RAM amount? Same printer? Same exact print driver version?
There are a lot of factors that need to be compared and eliminated before we can nail it down.
Maybe your friend should come and converse directly, in case you don't know all of the answers.
And me, I'm just a lowly Maccer trying to get more info so that the Windows brainiacs who might be able to offer answers will have more info to go on when they arrive.
In the meantime...I might suggest you review the following excellent document:

Using Presets for Printing Panoramas

I have created a generic preset for printing panoramas on an Epson 4900 connected to a Mac with OS 10.8.4. Using the Epson printer driver's Page Setup via Lightroom 5, I reset the length of the panorama for each print and then update the Lightroom preset. Everything else in the preset is correct for my prints (paper, profiles, etc.).
I have, however, periodically had the problem that even after resetting the print length in the driver and updating the generic panorama preset, that the print is the wrong length (either too long or too short) even though all indications are that everything is set correctly (see below). This can occur even if I shutdown and restart Lightroom (I have also had this problem in LR4).
I would like to known how to correctly set up a panorama so paper is not wasted due to an incorrect length.
The following items appear to be set correctly:
(1) Printer Driver Page Setup paper size
(2) The Lightroom Preset for the generic panorama (Both the print size and paper size. I looked at the text of the preset settings via TextEdit) I note that there is binary information at the bottom of the Lightroom preset. Is that being correctly updated?
(3) The print display in Lightroom (the image correctly fills the print template which is of the correct size)
(4) The print cell size in Lightroom is the size I have set in the printer driver
The different sized panorams were printed on different days and the printer was turned off between those days. Cut sheet prints were also printed in between the panorams.
One panorama was 8 feet long but it was truncated at 39 inches twice before it printed correctly (after I restarted Lightroom but not the printer). The other was correctly printed 58 inches long but on 8 feet of paper (which was blank after the image).
I find it hard to believe the printer is remembering an old size (even after being powered off) but if Lightroom is not sending new information, I suppose that is possible.

Hi Venu,
Don't know about best-practice, but you can do this by using the file adapter, using the "Run Operating System Command" to execute a print command on the file.
The file can be formatted in a mapping program.

Panoramic Printing Trouble on Epson 2200

I am trying to print a 8"x45" panoramic print from Photoshop in OS X 10.4.5 from Photoshop CS2 on a 13" roll of matte paper. I have the matte black ink cartridge in and have reinstalled the printer drivers to recognize the different ink.
I have created a custom page size in Photoshop, 12.94x45, and everytime I print the image, it is not centered and starts printing about 16" in from the edge. When it does print, it prints a thin line and goes over several times, then starts printing them image.
I have contacted Epson, and they have not given me any answers that have worked. They suggested I try the gimp print driver, but it has the same results.
I also imported the photo into a 13"x45" InDesign document, it starts to print in a different spot, but it is basically the same result. I tried making a PDF of the photo, and it has the same results. I also tried making the Photoshop document 13" wide, to see if it changed the outcome, no change.
Epson did say that the page setup is part of OS X 10.4, and not part of the printer driver now. Does anyone have any suggestions that might help me resolve this issue?

After many hours of going back and forth with Epson, I was reading in a Google group something about a limit on printing length. I shrunk the image to 40" and it is printing just fine.

CS5 Trial Panorama Question

HI
I am running the trial of photoshop cs5 on Windows 7 with a keen interest on the panoramic feature.
I have stiched 10 pictures together and I am impressed with the results.
The question I have is regarding saving the file. I only have the option to save the pano as TIFF or RAW
I have tried flattening (& merged) the image/layers, changing mode to 8 bit but I dont get the option to save as a JPEG.
I have seen some posts regarding the length of the pano but Im unclear if this would prevent saving as a JPEG.
Any assistance would be most appreciated.
all the best
Neil

In Photoshop, currently, JPEG images are limited to 30000 pixels in either dimension.
In general, JPEG images are limited to 65535 pixels in either dimension.
Yes, we need to make Photoshop's JPEG code handle larger images - we know.

Help required to make very large panoramic print.

I have a large panoramic picture which was stitched to gether from about 6 verticaly taken shots. The image size is currently about 7500 x 2500 pixels. This is almost exactly a ration of 3 wide to 1 high.
I found a local shop today that says it can can print it 63cm wide & any length I wish. This suggests that the maximun size they are able to print would be 63 cm high by about 190 cm long.
What sort of resampling would you suggest & what number of pixels would you think I would need to do this?

The rule of thumb is that a resolution of 240-300 px/inch is desirable for a decent print. With a large print, the resolution at the low end of the range should be ok, since the observer's eye is at a distance for viewing same.
One would like to think that the local shop would have guidelines based on experience with their equipment.
Have you checked with other vendors, e.g.Shutterfly, Mpix ?

How does iphoto4 handle panoramic pictures?

Hi,
My plans are to eventually get a camera that takes panoramic shots. Does iphoto4 handle panoramic pictures?
Thank you

Forestman,
From experience, I would suggest you consider buying software that can make panoramas from the photos you take with any decent camera.
I recommend PhotoShop ($$$) or PhotoShop Elements ($ the consumer version that has everything you will need.) There is surely good and inexpensive or free software out there but I don't use them.
Panoramas are very tricky. The Kodak manual Keith mentioned hints at that:
"NOTE:
For best results, use a tripod. (For a steady shutter release on a tripod, see Using the self-timer.) Only the panoramic picture is saved; individual pictures are not. Picture size is set to 5.0 MP. Exposure and white balance are set with the first picture. The flash is set to Off."
Exposure, white balance, focal length, camera angles, lighting and focus are critical for getting a seamless panorama. Good editing software can do the stitching together automatically (with good exposures) and give you the options for inevitable cleanup (even with good exposures). The software should also have tools for making those quickie handheld shots stitch (perspective, vanishing point)
The built in camera panorama feature may be good but it reduces it to a 5MB file.
That file might not be much better than cropping a high resolution photo to short and wide or skinny and tall.
Home printing is very limited -- you can only fit so much on a page. You might want to check into online printing services that offer panorama prints and see what the market is.

Automate Variable length frames

Hello,
I maybe heading in the wrong direction but hear me out.
I have a roll of film that is being digitally converted, right now to a video format can be any.
There are Variable length frames that are denoted by a large white space "They are not consistent length/time".
I need to extract those frames then turn them into a panoramic image.
I would like to automate this process, software or code doesn't matter.
I looked on the forums so far it does not look like Premiere would not be the way to go?
FFMEG perhaps?
Ideally I need something that will find that chuck of white space between the frames and extract. Perhaps writing code for a bitmap?
Any ideas would be appreciated! It would be awesome if Premiere could do this though!
Thanks!

Hi,
You can only create an Infoobject of maximum length 60 . If you are saying that it is text, you can store it as master data text , but there also in the long text you can store maximum 60 Characters .
Hope the above reply was helpful.
Thanks & Regards,

Photomerge panorama PSE7 wrong image order 360 view

Hi,
I have been using PSE7 and photomerge panorama for over a year on Windows XP with no problems. Recently I tried stitching together eight images which formed a 360 view. The problem is the resulting panorama is in the wrong direction, or image order. To clarify, the eight images were taken left to right of an ocean view from a forest bluff, with my back to the sun. So the sun is shining through the trees behind me, and image 1 is trees on the left side, image 2 is trees and ocean, with 3 and 4 being the ocean center and 8 being trees on the right side. The images are titled 1 thru 8, and they are ordered in the dialog box 1 thru 8. No matter what I do, all the photomerge panorama functions, except interactive, reverse the image order making the sun coming through the trees the center of the panorama, and not the ocean. So the panorama I get is always 4 thru 8, 1 thru 3 not the 1 thru 8 that I selected. All images were taken on a Canon G10 with 30% overlap for each image, on a tripod, no change in focal length, but some small variation in exposure. My only solution is to use the interactive feature, but the results are not nearly as good as using auto or cylindrical. The perspective option does not work because it is a 360 view.
Thank you to those who have read my mini essay to this point, and an even bigger thank you in advance if you can help me solve this challenge. So far I have not found this issue in any other post.
Cheers,
Ryan

Now that you mention it I've never seen any way to specify which image is leftmost.
You could create a slightly less than 360 degree pano, then merge the last image in separately... I suppose you'd still chance it going in on either end though.
Sure seems like a feature they definitely should have included.

Calculating and displaying the Length of the side of a triangle

Hi everyone. I am currently working on Dragging and Stretching a triangle on screen. Ive got it working to a certain extent but the only problem is that whenever I go to the point from which i have to drag my triangle i.e. the Left hand Corner of the BAse at exactly 300,300 it redraws a new triangle below the existing one and then when i stretch it from the top and the right it leaves a trail of triangles everytime. But when i resize my window it clears the trail only to start agian when I drag or stretch it...
All my code for wahtever I have done is displayed below. I would appreciate all the help that any one can offer.
Secondly , as I stretch my triangle I would like to calculate My Length of the hypotenuse and the other 2 sides as they change and display it in System.out.println for now...
PLEASE HELP

Hey sorry mate.. ive got a nother problem.
I need to add loads of theorems to this tool. so i need a JMenu Bar called File with all the normal things. then another Menu called Theorems where i can have a list of JMenuItems with the theorem names --- Like when they click on Pythagoras Theorem it opens up all the triangle and the traingle data that u helped me with.
The thing is im using netbeans and in netbeans i can do it coz its there and all you got to do is put the components together.
Please Help
Thanks...

How do I use Panorama / Tab Groups with the keyboard?

Yes I know that CTRL-SHIFT-E opens the panorama window, and then I can use the mouse to organize my tabs into groups.
But how do I do this with the keyboard?
I've [http://lifehacker.com/#!5719596/switch-between-tab-groups-in-firefox-with-a-keyboard-shortcut read] [http://ubuntuforums.org/showthread.php?t=1705714 that] Ctrl-`should move me through tab groups. That doesn't work for me on my Danish keyboard. (Where the ' and ` chars are weird. But is how they are on a valid standard Danish keyboard) I've tried changing the keyboard to USA and then moving through tab groups works fine.
In short: Pretend I don't have a mouse. How do I use Panorama / Tab Groups?

Sorry. These are both known bugs:
[https://bugzilla.mozilla.org/show_bug.cgi?id=587010 Bug 587010] - Add keyboard UI for manipulated groups and tabs in Tab Candy
and
[https://bugzilla.mozilla.org/show_bug.cgi?id=626594 Bug 626594] - shortcut for switching tab groups is badly accessible on many non-US keyboard layouts

Field Length issue in ALV Report

Hi,
I am using FM REUSE_ALV_GRID_DISPLAY to display few fields. Among them I have a field with length 200 characters text.
During ALV report display I am able to see only 128 characters, But when I download it and see the field, the it is showing complete text.
Can anybody help me out?
Thanks,
Ramakrishna

Check out the last answer of this post.
Re: ALV Grid Display - 255 characters
<i>I found a SAP document called "Using ALV for list display.pdf" that says the following:
"Size of data fields: While the list-based ALVList can display only tables of up to 90 columns, the control-based ALVGrid and ALVFullscreen have the limitation of 128 characters per data cell."</i>
Please make sure to award point for helpful answers and mark the post as solved. Thanks.

How do i find the length of a string??

trying to use the substring, I know the beginIndex (in my case 10), but the string will vary in size and so i need to find the last character and set it as the endIndex, how do i do this?
public String substring(int beginIndex,
int endIndex)Returns a new string that is a substring of this string. The substring begins at the specified beginIndex and extends to the character at index endIndex - 1. Thus the length of the substring is endIndex-beginIndex.
Examples:
"hamburger".substring(4, 8) returns "urge"
"smiles".substring(1, 5) returns "mile"
Parameters:
beginIndex - the beginning index, inclusive.
endIndex - the ending index, exclusive.
Returns:
the specified substring.

Hi
To substring the string where u know the begin index and want to extract till the end use the following function from the String class of the java.lang package
String substring(int beginindex);
String test = "Hello";
String xx = test.substring(1);
The Value stored in xx will be ello
This is in case u need till the end of the String
If wanna skip the last character u can
use
String substring(int beginindex,int endindex);
String test = "Hello";
String xx = test.substring(1,test.length()-1);
The Value stored in xx will be ell

How can I upload a 360° Panorama Review on my Adobe Muse Website?

Hey guys
I need your help, because nobody knows, how I can upload a 360° Panorama Review on my Website. First I loaded the whole file folder (picture 1) with all the data files (images, index, tiles and so on) in the document root on the server (pic 2 + 3).
After that I went back to my website and clicked on data - place and placed only the SWF file on my homepage and then I upload it as FTP Host to the server. And now it looks so: www.gardendreams.com
But it should look like this: Gartenpflege & Gartengestaltung Limmattal Zürich | Natursteinarbeiten, Wasseranlagen, Garten Neugestaltung, Pflanzberatu…
What did I do wrong? Thank you very much for your help.
P.s. I work with Windows 7 Professional 64bit

Hello Sanjit
Thanks for your answer. I need a little bit more help, I tried it, but I don't know how it works...
I found the html file and clicked on object to insert the html file, and then I took this code (see picture):
when I go to site preview I see this:
what must I do, step by step to upload this panorama? It would be great if you could help me. Thanks

How can I see track length in a playlist in music on iPad.

How can I see the track lengths in a playlist in music app on iPad the new version ios7, it was fine before. I use it for my work and need to see at a glance the length of all the tracks in a playlist so I can decide what track to play. Thanks

You can only add folders to the email account if it is an IMAP account. If you see an EDIT button at the top of the window when you are in the email account - where you can see your inbox, sent and trash folders - if there is an edit button at the top of that window - you can tap that and then an Add Mailbox option appears at the bottom of the window.
If you do not see that edit button, you do not have an IMAP account and you cannot add folders.

Hi Vidyanand,
Did you create the runtime access user using the runtime assistant? Did you select the correct runtime repository (if you have more) to associate your runtime access user with?
Note that there are 4 database roles being created when you create a runtime repository owner:
- OWB_A_<runtime repository owner>
- OWB_D_<runtime repository owner>
- OWB_R_<runtime repository owner>
- OWB_U_<runtime repository owner>
If you would grant those roles to a user, then that user becomes an access user for the user with username <runtime repository owner>.
Note that you can also use the runtime repository credentials to connect to the runtime repository for deployment purposes, but you may not want that because of security concerns.
Thanks,
Mark.
