Investigating PNG thing. It seems to like some and not others. It’s a discerning downscaler apparently.

Updated system to see if that’ll help.

@Andrew116 can you try the same png in this thread again some time please?

I tried it again and it didn’t work, this seems to have something to do with the files from DCS

Because other random pngs seem to work.

I wonder why ED started having the screen shots save in .png…? All along they have been saving as jpgs up until now it would seem.

Testing some other .pngs

Thanks for the testing everyone, I just converted all my screens to jpg and changed an option in the autoexec.cfg so I will hopefully get jpg’s for my screens from now on

@Freak and @Andrew116 - Can you do me a favor and upload a .zip file to this topic containing an example of a PNG that didn’t work for you please?

I’ll look at the binary header of the file and figure out where the scaler choked. It’s something new, so pretty sure I can fix it with a good couple of examples I can use - Cheers! :+1:

Thanks Gents.

DCS is generating vaguely corrupted PNG files, in that no header info correctly exists. The worlds most popular linux image manipulation library rejects it, which is what the forum software uses (an Imagemagick derivative). Things like Windows and OSX show it ok, but things choke when converting it.

I’ve reported back to the forum software mothership, plus have some workarounds to try as well.

We should also communicate that to ED so they just fix DCSW in that regard.

Plus I could ping @bignewy in that usual unprofessional way that has now become my trademark. :wink:

Very good! :smiley:

Just replied to the thread. … :slight_smile:

I will highlight this to the team, thanks

If you wish to change back to jpg you can

c:\Users\username\Saved Games\DCS.openbeta\Config\autoexec.cfg

if you dont have autoexec.cfg create one.

add the line

options.graphics.ScreenshotExt = “jpg”

That should work

Yep, can confirm now. The latest DCS screenshots in PNG format can’t be uploaded to Twitter, imgur.com etc or here, as they are rejected as corrupt images. I’ve set the PNG setting not to turn into a JPG to work around this for now here on the forums, but it can mean that large images get posted into threads and then slow them down, i.e. people on mobile/tablets etc.

If anyone has any performance problems in a screenshot thread or something then please holla and we can put the setting back (with the workaround you’ll need to convert to jpg like @bignewy has shown above).

Edit: I reread what you posted and misread it the first time, thanks for the fix!

Yeah, it’s not fixed :slight_smile: I’ve just let it keep the big PNGs for a bit until DCS screenshots are fixed or we can find a way to convert them. Basically either just convert to JPGs yourself, use bignewy’s suggestion above or at least keep the DCS screenshot PNGs as small as you can (just to be kind to mobile etc users on tight bandwidth).
