Hello,
I need to draw NSString rotated to 90 degrees. Now I have the code:
NSRect rcWhereToDraw = NSMakeRect(........); // <- rect is already
"rotated" here
[str drawInRect:rcWhereToDraw withAttributes:attributes]; // string
will be drawn non-rotated
as far as I know, I need something like this:
[[NSGraphicsContext currentContext] saveGraphicsState];
NSRect rcWhereToDraw = NSMakeRect(........);
float dx = NSMidX(rcWhereToDraw), dy = NSMidY(rcWhereToDraw);
NSAffineTransform *tr = [NSAffineTransform transform];
[tr translateXBy:-dx yBy:-dy]; // center or rect will be the center of rotation
[tr rotateByDegrees:90]; // rotate it
[tr translateXBy:dx yBy:dy]; // move it back
[tr concat];
[str drawInRect:rcWhereToDraw withAttributes:attributes];
[[NSGraphicsContext currentContext] restoreGraphicsState];
This doesn't work, where am I wrong?
Thank you.
