Hello all, I discovered macruby since a few weeks and I'm really enthusiast. I begun playing with it and really like the hotcocoa approach, but it seems stopped since more than a year, is it still maintained ? Anyway, I think I found a bug in the hotcocoa canvas part: the text method draws at a very big size regardless of the chosen font. The problem is that the transformation matrix for the text is not set. Here is the fix if anyone needs it: module HotCocoa::Graphics class Canvas def text(txt="A", x=0, y=0) affine = CGContextGetCTM(@ctx) CGContextSetTextMatrix (@ctx, affine); txt = txt.to_s unless txt.kind_of?(String) if @registration == :center width = textwidth(txt) x = x - width / 2 y = y + @fsize / 2 end CGContextShowTextAtPoint(@ctx, x, y, txt, txt.length) end end end
