[Fxruby-commits] CVS: FXRuby/examples image.rb,1.11.2.1,1.11.2.2

[Lyle J. <ly...@us...>]

Update of /cvsroot/fxruby/FXRuby/examples
In directory usw-pr-cvs1:/tmp/cvs-serv5170/examples

Modified Files:
      Tag: release10
	image.rb 
Log Message:
Modified the interface to FXImage#data so that it returns an
FXMemoryBuffer instance instead of a string (See SF Bug #550996).
The primary difference is that FXMemoryBuffer wraps the actual
data pointer stored by the FXImage instead of making a copy; this
way you should be able to modify the buffer and re-render the image
as you can in C++.
