fearlessfrog Posted December 3, 2017 Share Posted December 3, 2017 In the 1.5.8 recent release it seems the print screen seems to output a PNG file. What is new is that the PNG seems to have a corrupt image header. Example: https://mudspikefiles.s3.amazonaws.com/PNG_problem.zip Using a popular image processing library to convert it to a jpg, such as ImageMagick > identify -verbose Screen_171203_123000.png identify: Expected 8 bytes; found 0 bytes Screen_171203_123000.png' @ warning/png.c/MagickPNGWarningHandler/1832. identify: Read ExceptionScreen_171203_123000.png’ @ error/png.c/MagickPNGErrorHandler/1806. identify: corrupt image `Screen_171203_123000.png’ @ error/png.c/ReadPNGImage/4077 This means we can't resize/rescale DCS screenshots on the Mudspike forum software. Thanks for any info or help. ~~~ http://www.mudspike.com Link to comment Share on other sites More sharing options...

fearlessfrog Posted December 3, 2017 Author Share Posted December 3, 2017 Great - thanks for the quick response. Our forums software converts PNG uploads to JPG previews to speed up big thread load times and the like. The bit it is now failing at is the PNG conversion, as it thinks it is corrupt. I've put in a workaround to turn off that, but it means people will get to see lovely Harriers at 3 MB a pop rather than the measly 200 kb JPEG will used to give them (unless you click on the image). 1 ~~~ http://www.mudspike.com Link to comment Share on other sites More sharing options...
ED Team BIGNEWY Posted December 3, 2017 ED Team Share Posted December 3, 2017 (edited) It has been mentioned in another thread, and I have added it to a bug report for ED Screenshots don't have "end of image = IEND" chunk. according to PNG 1.2 Specification, PNG files must contain IHDR chunk, one or more IDAT chunks, and an IEND chunk. http://www.libpng.org/pub/png/spec/1.2/PNG-Chunks.html Because of missing the chunk, Twitter says that "this file is invalid". https://forums.eagle.ru/showthread.php?p=3309212#post3309212 Edited December 3, 2017 by BIGNEWY 1 Forum rules - DCS Crashing?

SkateZilla Posted December 4, 2017 Share Posted December 4, 2017 I like this, actually. Can the autoexec.cfg be given a options.graphics.ScreenshotExt = "png" to force them to PNG after this feature gets "fixed"? Also, what are the JPEG quality parameters? This page https://www.digitalcombatsimulator.com/en/support/faq/505/ just says... options.graphics.ScreenshotQuality = “screenshot quality value” ...but doesn't describe what the value should be. Integer? From what to what number range? Higher is higher? Are the quotes included? Thanks.
