Re: ImageList_GetImageInfo - alter the bitmap(s) ?

Indeed it does.  Having the bitmap(s) is where my problems started. :-\

Yep, I found the first one too (as well as GetBitmapBits).  But I realized 
that it takes a *lot* of work to be able to create something generic from it 
(for instance, it would need handlers for all 6 BPP modi).

Also SetDIBits needs a BITMAPINFO structure filled in with stuff I /somehow/ 
would need to extract/copy from the origional bitmap.

The easier way (I think) would be to use CopyBitmap, load it into a 
memoryDC* and use that to make the alterations on.

* which I would need to make sure it would have the same configuration 
(Image List Creation Flags) as the one the ImageList was created with.  In 
short: another problem.

... but that than has a "how do I get it back into the origional 
bitmap/imagelist ?" problem.

I was hoping that the MS way would show me a simple, smart way to circumvent 
all that clumsy work.

By the way:
for one test approach I invoked "the dark arts" and retrieved the 
memoryDC(s) the ImageList uses internally.  Drawing on them works as 
expected, very easy. Though there are a number of gotya's to recon with.  As 
well as the use of "the dark arts" ofcourse. :-)
