A "monochrome" bitmap is just black-and-white. If a grayscale PNG has
more colors than black or white, it will be loaded the same way as a
color bitmap.

We never imagined limits on Planet. Indeed, we tend to think
of 'applications' as potential components, so I see no problem
with posting such applications.
I think LGPL is much preferred over GPL. -- Matthias

I was thinking of turning of type checking and the translation of types into
contracts. (Unless I misunderstand your mini language, I think you're cheating
in a more fundamental manner "-)

Hi there!
I use Racket v5.3 on Windows XP and trying to understand how DrRacket and
gracket works. I found "racket\collects\mred\private\wx\win32" - as I
understand, ffi bindings to user32.dll, a win32 user interface
implementation. Can I (and how) configure DrRacket and gracket works on
win32 vers
You can try setting the PLT_WIN_GTK environment variable, which will
cause "racket\collects\mred\private\wx\platform.rkt" to select the Gtk
backend under Windows.
I haven't tried it in a while, though, so I don't know how well it will
work (i.e., I gave up the idea of really supporting that mode).
Moving to dev so as to not upset the locals with preliminary results. :D

That's the only thing I am talking abou
I can't recall why exactly now, but there is something about how the
contract system wraps first-order contracts that lets things run
faster.

Hi,
I've been working with redex (a little bit) trying to work my way through
"Semantics Engineering". Is there anything resembling an idiots guide to
programming languages? The specialized terms in Semantics are slowing me way
down. It probably is necessary to have that approach. In that c
Hello.
I would like to make a program that translate from Racket to Common Lisp.
One motivation is speed, for example a recent example in the racket blog about
the 2n+1 problem gives 1200 milliseconds in Racket and 500 in sbcl (without
declaring fixnum or any other optimization).

It is flattering for the Racket language that someone would go to all
the trouble of making a translator so that they could continue to
program in Racket, even though they were using a Common Lisp backend. :)
