Why is the border on my png file pixilated?

I just created this transparent graphic and the border is pixilated. I have resized it or anything. What am I missing?

...or you can get GIMP or Fireworks to produce a proper PNG8 with alpha transparency. For some bizarre reason, Photoshop cannot do this. See here for a Photoshop workaround.
There is no need to include the background in a web button graphic. PNG8 images with alpha transparency look fine in modern browsers and appear well enough as 1bit transparency in IE6.

Take screenshot and saves the image to a PNG file

Hello,
How can I take screenshot and save the image to a PNG file?
thanks,
Avivit.
Solved!
Go to Solution.

this is a quite reproducible problem. Some more clarification on my part might help:
I have a loop that contains, among other this, (1) a sub-VI that prints-screen and saves as a png and (2) a sub-VI that emails me the png file as an attachment. The 1st sub-VI simply uses the user32.dll to simulate a print-screen key stroke, calls clipbpard get image, and then formats and saves the image to a png file using the built-in VI write-to-png. This loop should update this same png file, because the path does not change. However, I've noticed that while the loop is running the png file does not update. It simply keeps sending the 1st image it took. The image updates if the VI stops and is run again. I assumed the problem was either with the clipboard not updating or the file not writing.
I think the png file remains open while the main VI (i.e. this loop) runs because I cannot delete the file while the VI is running, only once it stops or is quit. Windows gives me an error that the file is currently in use by labview. Therefore, I think the file is not updated because it remains open.
I've attached the print screen VI. Feel free to stick it in a loop and give it a try if you don't spot something obviously wrong. I did not include the main-VI that I actually use since it contains a lot of instrument I/O, which would prevent someone testing the VI.

Why the border of a Png image is seen on final render?

Hi, my question is that i made a png image first in photoshop and used it in a AE composition. It has a background with ramp and also use Trapcode form. The thing is that when i render, the border of the image is visible (eventhough it doesnt have border because is a png), Then i take that image to illustrator to export from there, and the only thing that changed is that the line, from continuos changed to discontinuous (like seen in the image here). So the question is what can be happening? I inserted two png images and both generate the same issue and it doesn't matter on which order of layer is at. In the second image that i've uploaded here is better seen how the border appears in the composition...
Thanks

Well, thanks everyone for your answers. he thing is that i went to what Rock suggested but Interpret footage wasn't active so couldn´t hange anything there.
The next step, Photoshop and lke bogiesan said, i was using a png that cames from and image with white background, so switchng it to black background and then make the Png do make the trick. Thanks, this confirm that if one doesn´t have the answer(i coldn´t figure that was the origin background of the image), perhaps another do have the clue, so issue solved.
Regards

Why Can't I Open My PNG Files? Going from MAC to PC

I created .png files in Photoshop CS on my MAC. Now I can't open them in Photoshop 6 on my PC running Windows Vista. Why? The files open as blank. All .jpg and .psd files open with no trouble.

I just installed PhotoShop 6.0 on from an old disk (licensed) onto my laptop Toshiba PC running Windows Vista. I have had no problems so far except for this .png issue. I basically just wanted a high-resolution image with a transparent background. I suppose I could try to save them again as uncompressed .psd images on my MAC and try opening them again on the laptop...but I hate having to do weird things like that. png should work!

Why does the Palm Centro save my files as .php files?

Okay so I've been trying to download files from the internet and save them on my Centro. When I click on the link to download it, it shows the file as a .doc file which is good because it's a microsoft word file. but then when I actually click "Save", the file changes to "download.php" and I can't open the .php file on my Centro. So my question is, Why does the .doc file change to the .php file? And more importantly, how can I save the .doc file without it changing to .php?

Hi.. Welcome to the Palm forums. Any Palm device is going to convert any file saved to it to the format it needs to be able to read it. For .doc files, word documents, you need docs to go which comes with your centro for free. Docs to go 10 is required for office 2007 and is available free for a centro, go to www.palm.com/us/support select downloads under support & downloads then select a centro and you will see a link for bonus software on your cd. Find docs to go, download it to your computer and install. Then sync which will update and/or install docs to go 10 on your computer and your centro. Once that is accomplished if you want to put a office file on you centro you open docs to go on your computer, add in the office file and sync. After that if you update the file either on the centro or on the computer then sync both files will end up the same after the sync.

Why is The iTunes Library Extras.itdb file locked?

After my walk this morning I tried to connect up to iTunes to chargemy ipod and update my tunes and got an error message:
"The iTunes Library.itdb file is locked, on a locked disc, or you do not have write permission for this file."
WHY WHY WHY ???

I had the same problem after a "force quit".
1. Quit iTunes
2. Locate your iTunes folder in finder and open it
3. Locate the "iTunes Library Extras.itdb" file, right click it and select Copy "iTunes Library Extras.itdb"
5. Rename your original "iTunes Library Extras.itdb" to "iTunes Library ExtrasOld".itdb
6. Move the your copied "iTunes Library Extras.itdb file back into the same folder as i came from
Repeate 3>6 for the "iTunes Library Genius.itdb" file
Re-open iTunes, the error messages should now be gone.
This worked for me, anyway

Why does the 'change all' button for file extensions revert the program?

Hi Chaps,
I have a piece of analysis software produce a file with the extension .jdf and I need to open it with a particullar piece of software called Mestrenova to manipulate it. The problem is...jdf is also the extension of the Adobe acrobat job definition file. I can go into the file in snow lepord with 'get info' and change the individual files to default open with Mestrenova BUT as soon as I hit the 'change all' button, ALL .jdf files revert back to Acrobat defualt. It's infuriating and I have no idea how to resolve it without installing 3rd party software, which I'd rather not.
Can anyone help?
Thanks

I still have this problem...

Why does the audio in my .SWF file not play in a Browser?

I created an .swf file using ffmpeg, containing H.264 video and MP3 audio. The file plays perfectly in VLC but not in a Browser (Chrome/IE). I tried analyzing the file using a trial version of Flash decompiler. Again, only the video plays. The strange thing is that if I extract the MP3 from the file, it plays perfectly using any of th eplayers. It seems to be a muxing issue which VLC apparently handles, but not the player in the browser! Why? Thanks for any pointers.

Yeah. Sorry to say this but many people buy the various brands of format converters, which are everywhere on the Web and which also spam these boards – and often find they are not only out the purchase price but that the app created as many problems as it solved.

Why do the last 3 or 4 files open when I click one file?

Is "resume" the reason why 4 or 5 of the most recent files I worked in open when I double click on a file that a) opens an application, mostly MS Office 2011 and b) and then the file I wanted? ***??? I end up closing a lot of windows to get to what I wanted. Whatever it is unchecking the resume box in the sys pref general tab has not fixed the problem. Lion is a disaster...

Why is iWeb converting all my PNG file to JPG upon publishing

When I drag and drop a PNG image to iWeb, it shows up fine in iWeb, but once I publish it to either my site or to a folder, all the PNG images are converted to JPG with a very low quality....
Is there anything i can do to stop iWeb from changing my image file?
THX
I'm using the latest iWeb 09 3.0.1

I don't think you can. I ran a test on this demo page.. All images ended up as jpgs and at about the same file size.
The only files that do remain png are transparency files.

Why is the size of my pdf file so large

In the templet,I use a font type "Simsun" for Chinese in the subform.
This font type is added in the output desginer by "font setup" .
And this font has been existing in my os.
When I generate a pdf file, the size reaches >6M.

George Johnson wrote:
Even if you specify Helvetica, Acrobat and Reader substitute a private version of Arial anyway, so all you're doing by specifying Arial is needlessly adding space. The problem is you can't go back and the fields to use Helvetica and see the file size reduction you might expect. This is due to what I consider to be a bug that I'm hoping will get fixed. So you have to start with a fresh PDF, but you can copy the old fields to the new if you first change them to Helvetica. Or if you know how to hack the PDF you can salvage it after changing the fields to Helvetica.
I was JUST about to type this. I went into my revised pdf and changed the form text boxes to Helvetica and it didnt change the file size. However I re-created the file from scratch and it is now keeping the file size at the original size. Thanks to both of you for the help!

Why has the opening of a Pagemaker file into InDesign CC been removed?

We receive many publications that have been produced by Pagemaker. We open and convert to InDesign for our publishing input. InDesign CC has removed this feature which now means we will have to always keep InDesign 6 installed on our system.

Don't expect an official Adobe "answer" to this question. This is my opinion.
Anyone who has observed the graphic arts field the last decade or so has seen this coming. According to Wikipedia, "The last major release of PageMaker was 7.0 in 2001, after which the product was seen as "languishing on life support". Adobe ceased all development of PageMaker in 2004 and "strongly encouraged" users to migrate to InDesign, initially via special "InDesign PageMaker Edition" and "PageMaker Plug-in" versions that added PageMaker's data merge, bullet and numbering features to InDesign, and provided PageMaker-oriented help topics, complimentary Myriad Pro fonts and templates. From 2005 these features were bundled into InDesign CS2, which was offered at half-price to existing PageMaker customers."
With the arrival of InDesign CC, the entire application has to be re-written for 64 bit and, on the Mac, using a different set of system calls. The number of people who still use Pagemaker are minuscule, and it wasn't worth it to port the feature over. Since InDesign CS6 still supports importing Pagemaker files there is a route for the tiny number of people who need to feature.
I'm pretty sure that this will not change in the future so you should get used to it.

Why are the PDF files in v27 bigger than in v25?

I have just created a v27 version of my single iOS app, which has been v25 before. Now the app has a size of about 550 MB instead of about 430 MB. I found out that the PDF files of the slideshows are bigger than before. What is the reason for this change and is there a way to get smaller file sizes again?
Kind regards
Michael
No idea? At least someone of the staff should know why the DPS creates larger files now.
There is another issue which indicates that Adobe doesn't care about file sizes. In slideshows the DPS always uses PNG files (if you don't choose PDF files, which are larger now, as I have told you). Of course it is because of transparency, but it would be easy to let the user choose between PNG and JPG like Twixl does.

You should report this via Gold Support who will investigate this. Minor file size changes will always occure on releases, however since you report the size change is significant, there may be some issue and needs further testing.
