Ben,
Some suggestions that came to me while I was working on that alpha channel
macro of mine:
When I issue the 'area' ARexx command, the user must use the current area
selection tool; this is most unfortunate if the 'entire image' button was
selected before the macro was invoked — it leaves the poor user with no choice
but to proceed, having selected the entire image. Solution: the user should
have access to the tool palette to change tools, if they wish, before selecting
an area.
There should be a "grow selection" and a "shrink selection", as in Photoshop.
It would be nice to have a better choice of ARexx area selection commands; for
example, I can have the user circle an area ('area'), analyze its color
contents ('cdef') and set Imagemaster's key color from the results
('colchange')… but then, I'd want to specify "color keyed selection", and I
can't do that in a macro. If memory serves me right, 'entire', 'oval', 'rect'
and load/save mask are the only area selections available from ARexx.
Other than that, I must say Imagemaster worked like a champ. The new Gaussian
blur operator, when applied with a small radius, is very fast and produces
results much better than the naive edge detection found in the "smooth edge
transparency" blend control. Rolling your own alpha channels using Blur is
definitely the way to go, although "smooth edge transparency" is still great
for quick & dirty use. I sent the macro to a friend, and even added an
interface feature over the phone, by having him key in two extra lines of ARexx
code. (He wanted to alter the variance after selecting an area) Ben, I had so
much fun working with Imagemaster and ARexx this weekend!
Blaq!
