[csjava-developer] TheMatrix & Alpha values

[Daryl V. H. <dva...@sf...>]

I just realized that TheMatrix isn't saving Alpha values that it's given.

When the BufferedImage is created in utils.Utilities.java, it's created 
with type TYPE_INT_RGB, which doesn't save Alpha values, instead of 
TYPE_INT_ARGB, which does.

Also, to create a Color object from an RGBA packed integer, using new 
Color(int) ignores the Alpha value, when you use new Color(int, boolean 
true) it actually copies it.

Another thing is when you're drawing an image with transparent pixels 
onto another image (see utils.Utilites.java, method BufferedImage 
makeBufferedImage(Image image, int image_type)) it doesn't copy the 
Alpha values, it just blends the pixels with alpha values with the color 
that's already there (usually black), which probably isn't what we want, 
is it?

I found this out by reading the JavaDocs, looking for information for 
another project I'm working on (if you want to know, NQL, Not Quite Liero).

If you want these problems fixed, I think I'd like to volunteer (unless 
you think I'm working on too much already).

Daryl.
