Custom Imported kneeboard png shows up red

[Darkdiz]

I recently created several png files for the kneeboard.  Previously, these have shown up correctly, white background.

However, the last set I created show up on the kneeboard with a red background, even though in any graphics program (GIMP, and of the Windows graphics apps) they show up as expected with a white background.

The pngs were created by exporting a MS Word page to pdf, then exporting the pdf page as an image png. This has worked fine before, and the old ones I still have in the kneeboard folder show up correctly.  The one page that DOES show correctly has an image embedded in the original file.

Any ideas?

Please attach two pictures: one that shows up red and one that doesn't.

I got it to show up correctly. If the png has only 2 colours (black text, white background), in DCS the background shows up red (at least for me). I fixed it by by making some of the characters in the working png red, and now it appears normally.  Weird in that in all of the other graphics programs the png appears normal.  I'll take a screenie of both...

I also attached both files.  01a shows up red on the kneeboard

Strange. I've been using the GIMP for more than 20 years and it never did such a thing to me.

Ensure you're using PNG export default settings. Once you see this window (sorry, French GIMP), hit "Load default".

The method I use is to save the selected pages from MS Word as a pdf, then export the pdf from Adobe to png. This has always worked fine prior to today, I have created a multitude of pages for my kneeboard folder, all displayed correctly with default settings. GIMP was not involved at any time in the process.

I thought it might have been a DCS setting or something in a lua file somewhere, but I noticed that one of the pages I exported rendered correctly, it had multi colours in it. I ended up making the para numbers red, and it solved the issue (or at least band-aided it)

Oh OK, then it's Adobe (Writer?) which compresses PNGs too much. I'm pretty sure DCS handles 16bit and 8bits PNGs OK. I'll do some tests and report back.

Here you go: your black & white picture has a color depth of 1, while the red/black/white one has a standard color depth of 24.

Ok, so I guess its in the Adobe export? Just make it more colour depth?

[Flappie]

Yes. Check your Adobe software. When about to save as PNG, you should be able to select between compression levels.

Well done. I adjusted the Adobe export setting to make the png colourspace RGB instead of auto. Worked fine.

Thanks for the quick response

You're welcome.
