DrJimi Posted April 28, 2010 Share Posted April 28, 2010 (edited) PDN v3.5.5 (Final Release build 3.55.3767.28608) Windows 7 Ultimate 64-bit with .NET Framework 3.5SP1 & all latest updates as of 4/28/2010 This is a dev machine with VS2008SP1 & Expression 3 installed. I opened a JPG, cropped it slightly, and then saved it as a PNG. I chose the PNG file type in the "Save as type" combo box. In the Save Configuration window, the preview shows only a small black dot centered in the window and the label "Preview, file size: (computing)" never changes from "(computing)". Bit Depths of Auto-detect, 32-bit, and 24-bit produce the same results. Selecting a bit deptch of 8-bit causes the file size label to toggle continuously between "(computing)" and "(computing: 100%)". The resulting PNG file cannot be displayed in Windows Photo Viewer or opened with PDN. I have attached a sample of the output file generated as above with the explicit selection of 24-bit PNG. Save As JPG and BMP work fine. Pasting a screen capture into a blank image and saving that as PNG works, too, so it may be something specific to this image or the fact that the source image is JPG. I can upload the source JPG image if desired (it is 644K). Edited April 28, 2010 by DrJimi Quote Link to comment Share on other sites More sharing options...
pyrochild Posted April 28, 2010 Share Posted April 28, 2010 Try running pdnrepair.exe in C:\Program Files\Paint.NET (or wherever you installed Paint.NET) If that doesn't help, please post the original JPG here.

DrJimi Posted April 28, 2010 Author Share Posted April 28, 2010 pdnrepair had no effect on this problem. I'm unable to upload the source JPG as an attachment as it's 644KB. Is there another upload mechanism you'd like me to use? Quote Link to comment Share on other sites More sharing options...
Sarkut Posted April 28, 2010 Share Posted April 28, 2010 (edited) You could use: imageshack.us or tinyupload.com Edited April 28, 2010 by Sarkut Quote Link to comment Share on other sites More sharing options...
DrJimi Posted April 29, 2010 Author Share Posted April 29, 2010 OK, the source JPG has been uploaded to http://s000.tinyupload.com/?file_id=09239349294201645607 Quote Link to comment Share on other sites More sharing options...
pyrochild Posted April 29, 2010 Share Posted April 29, 2010 OK, this issue reproduces for me. Quote ambigram signature by Kemaru [i write plugins and stuff] If you like a post, upvote it! Link to comment Share on other sites More sharing options...
Rick Brewster Posted April 29, 2010 Share Posted April 29, 2010 Same, although it works if I manually select 32-bit.

Rick Brewster Posted November 17, 2010 Share Posted November 17, 2010 I've found the problem. The image has an embedded ICC profile (EXIF tag ID #34675). When saving a PNG with this at anything other than 32-bit, this appears to be totally broken. I don't know if it's because GDI+ mangles it while saving, or if the PNG spec just says "if bpp isn't 32 and you have a 34675, then you are dead to me." This will be fixed in 3.5.6.

TheOriginalDude Posted November 29, 2010 Share Posted November 29, 2010 Hello! I am having the same issue with creating and saving any type of .tga (targa) file. If I rename the file extension to .jpg I am able to open the file with paint.net. I am currently using version 3.5.6 on Windows 7 Home 64 bit and the only reason I am making this post is beacuse it was previously mentioned that this similar error with .png was to be corrected with the version I am currently using. Knowing very little about programming i was curious if this fix was only relative to the .png file types or if it had to also be corrected for the .tga files as well. Pretty much the only thing I use paint.net for is for the creation and editing of targa files and this is the first issue I have had while using this program and those file extensions. Would really appreciate any help with this! Great program by the way. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
pyrochild Posted November 29, 2010 Share Posted November 29, 2010 If it works when you rename the file, it sounds like you're changing the extension to .tga instead of choosing TGA from the filetype dropdown when saving.

jimmycthomas Posted December 3, 2010 Share Posted December 3, 2010 I think these results show that the registration of your images as PNG-24 can be a better alternative to save the photo in JPEG format with a quality of 100 at times. PNG preserves the quality of the discharge on the Internet. The only drawback I can see to save your image in PNG format is that some photo sites/galleries will not let you download it there, PNG, JPEG, etc. Quote Social Media News and Information Technology Updates Link to comment Share on other sites More sharing options...
