I downloaded, and installed, Patch 4.1 this morning.
I ran the program I'm working on, and ALL of the sprites have Black Squares around them.
Changing the values of, or even deleting the "set image colorkey" command has no effect. I normally use values of "0".
And both my regular, and animated sprites have the black square around them.
No other adverse affects were noted.
There does appear to be a bit of an improvement in the image quality of the animated sprites.
Until this patch, parts of the sprites that should've been visible, were made transparent, now they're visible, as they should be.
Whether that is due to the "set image colorkey" no longer working, or not, is not known at this time.

I believe that TGA and PNG format files ignore the SET IMAGE COLORKEY settings (although I can't find the conversation now ).

The reason? Because they already have their own way of doing alpha.

Just change your black areas to a true clear value (alpha level 0) and that should sort it out.

Well, using BMP images work, like the PNG did before, but they're 9 times the size!
Instead of less than 2.1mb in total, now it's over 18.9mb!!!

Load them into a bitmap and use get image to grab them back. That should lose the alpha channel and give you color key back.

You need a decent program that can save png transparancy.
Mspaint isn't up to it unfortunatly.
I have used gimp http://www.gimp.org/~tml/gimp/win32/
I would think practically any recent image editor other than mspaint should be able to do it.

Well, first off, MSPaint can't convert to PNG.

However, I'd never even thought about saving the animation pages WITH the transparency.

It works!
Thanks for the idea!
