Thanks for the code sample. That works for drawing unrotated text, but
I can't get it to work with my rotated CGContext. The suggestion was
to rotate the CGContext and then use RB's Drawstring function. Below
is my routine. The CGContextShowTextAtPoint command draws rotated
text, but no matter where I put the graphics_DrawString command that
you provided I can't get it to draw into the rotated CGContext. My
guess would be that I'm not getting the CGContext of theRB Graphic
object properly. But the CGContextShowTextAtPoint command works.
void SKSDrawRotatedTextfunc(REALgraphics context, REALstring text, int
Rotation, int x, int y)
{
CGFloat rr,gg,bb;
Rect r;
unsigned long FontColor;
REALstring fontName;
float fontSize;
CGAffineTransform myTextTransform;
GrafPtr newPort;
CGContextRef myContext;
//Get RS Graphic properties
REALGetPropValue((REALobject)context, "ForeColor", &FontColor);
REALGetPropValue((REALobject)context, "TextFont", &fontName);
REALGetPropValue((REALobject)context, "TextSize", &fontSize);
rr = (FontColor >> 16)/255.0;
gg = ((FontColor >> 8) & 0xff)/255.0;
bb = (FontColor & 0xff)/255.0;
//Setup for Quartz
REALSelectGraphics(context);
GetPort(&newPort);
GetPortBounds(newPort, &r);
QDBeginCGContext(newPort, &myContext);
//Setup and rotate CGContext
CGContextSelectFont (myContext, REALCString(fontName),fontSize,
kCGEncodingMacRoman);
CGContextSetRGBFillColor(myContext, rr, gg, bb, 1);
CGContextSetRGBStrokeColor (myContext, rr, gg, bb, 1);
myTextTransform =
CGAffineTransformMakeRotation(degreesToRadian(Rotation));
CGContextSetTextMatrix (myContext, myTextTransform);
//draw text
CGContextShowTextAtPoint(myContext, x, r.bottom - y,
REALCString(text) , strlen(REALCString(text))); //draws rotated text,
but doesn't work with all fonts and is missing bold/underline/etc.
graphics_DrawString(context, text, x, y+ 50, 1000, false); //draws
nothing
//clean up
QDEndCGContext(newPort, &myContext);
graphics_DrawString(context, text, x, y+ 150, 1000, false); //draws
unrotated text
}
