[Alephmodular-devel] PicHandle->CBitmap double whammy

[Br'fin <br...@ma...>]

I've begun looking into what I need to do manage getting a picture 
resource and passing it around internally as a bitmap.

The starting point seems to be around the get_picture_resource_from* 
routines in images.cpp. We would need to muck with these so they are 
fetching the resource and dumping it into a CBitmap instead of 
returning it immediately. (I'm not going to worry about images.cpp 
being neutral or mac-like yet. AM has no platform neutral way of 
dealing directly with resources yet.)

My choices for that seem to involve
a) setting up a hollow pixmap, a temporary gworld and doing a draw 
picture followed by copybits.
b) importing the picture decoding from SDL and running with that

And because of the setup of things, I think going with the SDL picture 
decoder might be simpler for dovetailing with a CBitmap.


On the other side of things, CBitmap itself still has no place for a 
color table. (From a couple things in the pass, this might be advised 
in certain locations) and the current carbonized draw bitmap routine 
appears to be expecting all CBitmaps to be 8 bits per pixel with a 
color table. (Prepared before hand and setup before the bitmap is used)

I need to flesh out both sides of this equation. Hsm.
