Hi,
I'm working on an application framework (using Carbon) that draws text via ATSU functions. Initially I drew text straight to the screen without passing ATSU a CGContextRef via ATSUSetlayoutControls, but the text would look terrible; bad kerning, bad anti-aliasing... just ugly. I think this case is delt with in the Apple documenatation here:
http://developer.apple.com/documentation/Carbon/Conceptual/ATSUI_Concepts/atsui_chap4/chapter_4_section_7.html
So I'm trying to fix that by having a global context like it says and so far it's been really rough going. Firstly text only appears on the first window and then I get no text on the 2nd window. Also now all my text is drawn relitive to the window instead of relitive to the control currently being painted. Heres how I create my context (just once):
static CGContextRef GlobalContext = 0;
if (!GlobalContext)
{
CGrafPtr port;
GetPort(&port);
QDBeginCGContext(port, &GlobalContext);
}
Am I using the wrong method to get the port?
Do I need to create a CGContextRef per window?
Is there some easy way to map output into the bounds of the control (HIView) currently being drawn?
Regards
