Quick Look Index View and PDF hidden content

I have come across an odd quirk of Quick Look in which the Index View is different from the regular view. The Quick Look Index View of two or more PDF files will show hidden page or image content, while the regular view of the individual files will not.
The hidden content consists of one portion of the text covered up.
Preview does not show the hidden content of an individual file, but QuickTime does.
Is this inconsistency of Quick Look a bug?

VikingOSX, if I'm not using plug-in then I let Quick Look to not serving me at all!
Maybe I was not clear in my initial post. Index.html is not the file I want to see inside Quick Look. Index.html file I'm talking about is part of code BetterZip plugin is using to show Zip content. It is located in the Resource subfolder inside plugin. So my findings are related to html parsing issues Quick Look engine is doing inside plugin.
Once again, I'm not talking about HTML quicklook plugin that is already built-in to show HTML files, but BetterZip plugin that is designed to show compressed file contents (e.g. zip, tar, ...).
Does someone know if there are some changes in the behaviour of Quick Look engine or if there are some bugs in Quick Look engine for Mavericks 10.9.0 that parses internal plugin html contents incorrectly (or to load external html resource files)?

How to view and manage hidden files in folders.

Hi all, my question is: How to view and manage hidden files in folders?. I see hidden files in other computer but no in my Mac.
Some of you can help me?
Thanks..

Most hidden files are hidden for a reason. Tampering with them can seriously affect the stability of the system.
The software Tinkertool can

Color is Wrong in Preview / Quick Look when viewing photographs

Hi All,
I have a problem in that all my photos and image files look a lot more saturated in Leopard Preview / Quick Look, with much warmer hue, tint and color temp, then they do in either iPhoto, Aperture, Photoshop Elements, Safari (or Firefox) when uploaded to the Web and even in my Windows XP VM using the normal Explorer application. The difference is very visibly and is unacceptable when viewing / editing photos.
To summarize, it seems the only place images look different, much more saturated with more warmer tint and hue, is in OS X Leopard Preview and Quick Look.
- I have tried viewing and comparing on another Macbook Laptop and do not notice this problem, which leads me to believe that there is a problem with my system.
- I have also tried creating another user account on my Mac and logging in to preview the images, but it makes no difference.
Can someone please advise as to what I can do to fix the problem?
Thanks,
P

I have noticed the same. Seems like a genuine bug in preview.
Try this for laughs: Open up a picture in Preview and note its too warm colors. Make a screenshot, and view in preview next to the original image. The now magically warmer colors prove this is indeed a bug in preview.
Lightroom, PS, Safari, Opera all show the images in question (JPG, embedded profile: sRGB IEC61966-2.1) consistently correctly, with preview being the only exception a lazy comparison could find.
EDIT: This happens only on my external TFT. If I move both the Photoshop and the preview windows to the built-in screen, the Photoshop colors "snap" to look the same on both screens (and the same as preview on the built-in TFT).
There seems to be a problem with preview always applying (correct) color correction for the built-in TFT regardless of whether the image is actually displayed there or on another display. This is probably also only noticeable if built-in TFT and external display have noticeably different color responses (and thus corrections), and only when their colors are corrected.
This really is an annoying bug for photographers or other creative people (which Apple prides itself to cater to).

Discrepency in "actual size" view and PDF export result

I am working with a document and am confused about the size when I export it as a PDF. When I export it and open it up, the size of the fonts is considerably larger than those in my document in "actual size" viewing mode. Also, the page sizes are also larger, about 60 percent larger.
Also, will the size of the PDF vary on different computers?
I am creating an ebook so I want it to open in a favorable size for everyone, if possible...
Does someone have any guidelines?

What you're experiencing is just the magnification, or view settings. If you export to an interactive PDF from CS5 you can control those upon export. If you hover your mouse down the bottom left of the Adobe Reader or Acrobat window you will see the size of the PDF which will be the same as your Indesign document. My advice would be to try different view settings and see how they affect the finished PDF, there are a lot of options available which it would take a long time to explain. Also have a play with the layout.
You can also adjust these after export (for example in a Print PDF) with Acrobat, under File > Properties > Initial view and you then have the added option of making a navagation tab open by default too, which might be useful for your ebook.

Adobe Reader 9.2- makes documents black- cannot view the PDF's content

Hi all
Hoping someone else has seen this very wierd issue.
I have a Terminal Server running Server 2003 SP1. (inherited)
The End Users were experiencing issues with Reader not printing out correctly. They were previously using Reader v7.0.
I downloaded the latest version v9.2 off the Adobe website and it installed correctly.
The v9.2 installation has solved all the previous printing issues but has now created a new problem.
It is not every time but very regularly, if the users are opening PDF's on the Terminal Server, the content is blacked out and they cannot see the text.
It is like someone has taken a black marker and removed the text- SEE ATTACHED screenshots (it's like they do for Top Secret documents LOL)
I have checked that Reader has no updates available, I called Technical Support and they don't support Reader over the phone and directed me here.
I am going to re-install using the .exe off the FTP tonight but not hopeful that this will solve this problem.
Thanks in advance.

Hi,
I am successfully able to view PDF files on my Vista OS, without any black spots or any other obfuscating marks.
You should try to uninstall and then reinstall your Reader 9.2 from http://get.adobe.com/reader/.
If the problem persists, then you need to check any other installed software on your system, that's causing you problems because Adobe Reader's is an application to view PDF files, it does not creates any.

Mismatch column name in report viewer and PDF export?

I have text box in the header and populated dynamically.
If my query result is more than 1 page, when i go to next page, the column value will change but when i export it to PDF or Word, only the column value of the first page will appear.
Please see image below:

What's wrong here?

Hi Arun,
Here's the screenshot of the problem
-> {http://}i.imgur.com/2hGf3xi{.jpg}
Is the textbox is placed within report body or in the page header.
-> It's in the body/tablix, please see image below
->{http://}i.imgur.com/hiO0R8C{.jpg}
Can you provide the expression you have used in that text box
-> =ReportItems!STORENOG1.Value
-> I have a textbox STORENOG1 which is hidden (=Fields!STORENOG1.Value)
This is how I declare in my Stored Proc
-> STORENOG1 VARCHAR(10) DEFAULT NULL
Please remove the curly braces in the links bec. I cannot paste link and upload images

How to configure LabVIEW web server to allow viewing and accessing the content of a folders

I have added the following html line to the body of the html file generated by the LabVIEW Web Publishing Tool:
<a href="MyFolder" target="_blank">My Folder Content</a>
I expect the link labeled "My Folder Content" to open a new browser window displaying the content of "Myfolder" which is located inside the LabVIEW webserver root folder. I got an error instead. If I substitute "Myfolder" with a filename, the browser will display the file just fine.
Can someone provide me with some hints on configuring the web server for this purpose?

Hola Hector
Estoy trabajando con tu caso y se me ha hecho bastante interesante.
Solo te quiero preguntar... que version de Internet Explorer tienes?
Utilizas algun otro web server ? ( Mozilla tiene este problema me parece)
Segui los pasos que mencionas con Internet Explorer 6
y pude abrir la carpeta sin problemas.
Te pido por favor que me contestes estos datos para darte una solucion muy especifica.
lamentablemente tengas que hacer referencia directa ( todo el path) a los archivos del folder para accesar a ellos si tu explorador no lo permite.
Lo unico que puedo confirmarte es que parece no ser un problema de National Instruments.
sin embargo si me das mas informacion podemos descartar cualquiera de las conclusiones a las que he llegado.
Espero tu respuesta
Saludos

Can Quick Look but not open a PowerPoint file

Someone sent me a power point file, and I can open it in Quick Look both in Apple Mail and in the Finder. However, Quick Look doesn't allow me to enlarge it big enough to make out the details or to print it. Text Edit won't open it. When I try to double-click the file, the finder displays the message:
The document could not be opened. The file is not in the right format.
I have no idea why Windows users blithely send people files like this in proprietary formats under the assumption that anyone and everyone will have no problem opening them. However, since Quick Look can view this, is there another default program on the Mac that can actually open it?

OK, downloaded and installed NeoOffice, and it did indeed open and play the PowerPoint presentation--which, incidently, seemed to employ every single transition known to Microsoft, made me a bit queasy.
As to why Windows users are so enamored with presentations, danged if I know. And why they have to email the things to everyone they know....well, it's a mystery.
Anyway, you can get NeoOffice here:
http://www.neooffice.org/
It's open source, and thus has to be free. But if you actually end up using it very often, consider a donation.

Transparent background for Quick Look thumbnail

I am writing a Quick Look plug-in and would like to generate a thumbnail with a transparent background.
If I simply create a graphics context, flush it and exit, I see a solid white square for relevant file icons and Quick Look previews. I can find no way to clear the canvas to transparent - I can paint the contents of my thumbnail onto it just fine, but everything is composited to the white background.
For example, the following implementation(ish) of GenerateThumbnailForURL results in solid white squares for thumbnails:
CGContextRef context = QLThumbnailRequestCreateContext(
thumbnail,
CGSizeMake(512, 512), /* (For example) */
false, /* Changing to 'true' for vector context makes no difference */
NULL
QLThumbnailRequestFlushContext(thumbnail, context);
CFRelease(context);
return noErr;
Various combinations of CGContextClearRect with and without wrapping the call in CGContextBeginTransparencyLayer and CGContextEndTransparencyLayer, or trying to use CGContextFillRect having set a colour which is fully transparent, have all failed. The solid white background just shines through.
Am I going about this the wrong way (e.g. should I instead try to generate an image with a mask and send this to Quick Look with, say, QLThumbnailRequestSetImage ?) or is there some Magic Call that I should be using?
Thanks...

This isn't nearly as intuitive as I think this should be.
You're right, video is really hard.
Looking back over your thread, it's entirely possible the movies have transparency, you're just not looking at it properly, which is, granted, confusing. But alpha channels are not fundamental to video editing, they're special types of clips and you need to learn how to create and use them.
Motion is set by default to render to the Animation codec but may not be set to millions of colors +, the + sign is the alpha.
And, no, sorry, it can't be explained in a simple step-by-step post. There are fifty or a hundred pages on alphas in the Motion documentation. Start with the explanation of the Animation codec.

Some Pages documents do not show up in Quick Look properly

After upgrading to Yosemite, when hitting the Space button on some Pages docs to see them in Quick Look, all I get is a thumbnail of the doc next to it's title, last modification and size. This is not the issue with all Pages docs, but only with some. Other Pages docs will open in Quick Look just fine and I can scroll and read through them perfectly.
I completely don't understand why some Pages documents won't open in Quick Look, and some others do. I'm running on a 13" Retina Macbook Pro.

Viewing pdfs with Quick Look is too small in Lion?

I tried to search for this everywhere and I didn't see much input.
I'm a grad student in the biomedical sciences. I need to keep a large library of pdfs for my work and one of the best things about switching to a mac was being able to use quick look to quickly browse pdfs instead of having to open tons of files just to find what I need. Often I'll be looking for specific information and in Snow Leopard I could read an entire pdf article using quicklook because the pdf filled the screen.
In Lion quick look doesn't make the pdfs large enough to actually read, except for the title of articles.
In Lion I can't zoom in pdfs and I can't seem to get the pdfs very big with quicklook no matter if I am in full screen mode or resize the window etc. I don't actually even understand why full screen is an option for previewing pdfs in Lion because it only makes them fractionally larger than they are in the regular viewing window...(on a 13inch MBP anyway)
Am I missing something?
I just upgraded to Lion with the 10.7.3 update btw and I have spent the past several days tweaking Lion to get it back just the way I want it. This feels like the final stumbling block...
I guess I was just wondering
a) is there anything I can do to remedy the situation besides simply getting used to opening the files in preview (which of course I do eventually anyway)
b) am I really the only one bothered by this? It seems really subpar compared to how quick look worked in Snow Leopard but after trolling the web for about an hour I've found scarcly any mention of the issue...
Thanks in advance for any input and if by any chance this bothers you as well please send apple feedback (which I just did).

Ok, I will send this comment also to Apple feedback.
I appreciate your efforts to point out possible solutions (which I tried out before posting here).
Despite the fact that they don't work here (font resolution is too poor to be readable when enlarged through the magnifier) I would still consider this issue a downgrade with respect to previous versions of OS X just because it would require more efforts to arrive at the same results compared to simply enlarging the window with one mouse/trackpad move. A lower screen resolution can definitely not be the preferred solution. I'm far from being blind and I enjoy my current screen resolution.
Dragging things into the preview app is not favorable either: I want to have a quicklook and don't want to bother actually opening lots of files at a time.

Quick Look PDF with vertical and horizontal pages

Is there any way to make Quick Look preview a PDF file with vertical and horizontal pages without adding white padding and retaining the aspect ratio?
Now, if I have a PDF with page 1 vertical and the other pages horizontal QL shows the latter also with the ratio of a vertical page and adds white padding at their top and bottom. You get the inverse output if the first page is horizontally oriented, but the rest are vertical.

Word renders print jobs that change the orientation as separate print jobs. So, each print job becomes its own PDF.
You can make an Automator workflow to combine PDFs. I’m not sure how it decides the order it combines them, so you’d have to experiment.
This is built as an Application where you’d drop all of the PDFs onto the App icon and it will open the combined PDF where you can edit, name, and save.
