[comp.lang.smalltalk] Algorithms for BitBlt

ken@pdn.UUCP (Ken Auer) (01/09/88)

I'm looking for information/references on algorithms (or other information 
about) the following topics for BitBlt graphics ONLY!  

	drawing non-rectangular geometric figures
	manipulating those geometric figures and/or other figures/icons
		(scaling, rotating (0-360), mirror-imaging, etc.)
	clipping via some geometrical shape other than rectangles (e.g.
		clipping circles).
	3-D effects
	combination rules for multiple planes or chunky pixels 
		(color/greyscale BitBlt)

I'm currently working in Smalltalk, and know that some of this info is
already provided in the system, but I am interested in info both
specific to Smalltalk and otherwise.  I've currently got a small amount
of info, but I'm sure there's a lot more out there that I haven't seen.

Please reply via e-mail, I'll summarize.

				Thanks in advance,

				Ken
