I'm having trouble understanding exactly what is your question, but
looking at your code, I think you may have misinterpreted the
arguments for the FXImage#crop method. Here is the documentation:
http://www.fxruby.org/doc/api/classes/Fox/FXImage.htmlThe first two arguments to crop() are the (x, y) coordinates for the
top left corner of the crop rectangle, and the 3rd and 4th arguments
are the width and height. In your code, you call crop() like this:
@mywidth =
0.5*@...
@myheight =
0.5*@...
@image.crop(@mywidth, @myheight, @image.width, @image.height, FXRGBA
(236, 233, 215, 255))
So this says that it should start cropping in the middle of the
(original) image, but the resulting image should have the same height
and width as the original image. Can you maybe say what it is that you
expected to see, or what is your desired end result?
Hope this helps,
Lyle
