Re: Images going black
Indeed: and the end of a long line of beta operating systems running from macOS 10.15.0
to macOS 11.0.1, and, only with macOS 11.0.1 has this phenomenon with PNG images and LiveCode happened.

Re: Images going black
So . . .
I ran up a stack containing some PNG images I downloaded from the internet alongside PNG images made in GIMP.
- -
In the stack, as you can see, both images are rendered properly.
- -
In a Macintosh standalone the image from the internet looks fine, but the GIMP one does not.
This is odd as I never, in about 15 years, had this type of problem with a GIMP png image before.

Re: Images going black
In a standalone the PNG processed in GIMP fails, while the PNG prcessed in Photoshop 21 trial version succeeds.
Currently NOT running beta software: this is macOS 11.0.1 final.

Re: Images going black
That looks like all LC sees is the alpha channel.

Re: Images going black
Oddly enough Seashore ( a GIMP derivative) produces PNG images that behave themselves:

Re: Images going black
Richmond,
could you have a look at the color profiles of the different images? If you select an image on a Mac and then do command + i you get the info. There should be a section that indicates which color profiles those images use. If those are different from the Gimp vs Photoshop/Seashore then you could change the color profile of the Gimp png to a profile of the other ones. Use Color Sync.app for that.
This is just a hunch and might not be the problem but it is worth a try.
Kind regards
Bernd

Re: Images going black
You could also try to upload a zipped Gimp png that is not working and a zipped Seashor png that is working. I could have a look at them.
Kind regards

More than 3 options:
This is the Seashore one.

Re: Images going black
Whacko!
Thank you Bernd for your trouble.
- -
Now there are 2 considerations to point out re GIMP png images with their original profiles:
1. They appear perfectly properly in stacks.
2. On the first card of a macOS standalone they appear perfectly properly.
3. It is only on second and subsequent cards in standalones that these images seem to appear as their alpha-channel mask.

Re: Images going black
Glad it worked.
Maybe you can change the default color profile in GIMP?
Kind regards

Re: Images going black
That does seem a good idea.
But it will take me some time to located .icm files to do that.
