I am facing the following problems in drawing text and graphics in
CGContextRef of an NSview and Printing framework:
1) drawing text using: [finalString drawInRect:textBox
withAttributes:attributes];
Works nicely in my sub-classed NSViews in a CGContextRef obtained in the
drawRect : method with CGContextRef viewCtx= [[NSGraphicsContext
currentContext] CGContext];
But draws nothing in a print context obtained
PMSessionGetCGGraphicsContext(printSession, &ctx); //( geometry is perfectly
previewed,Pdf’ed and printed except texts .. )
2) filling a bezier path with a pattern Color
NSImage* nsPatImage= [[NSImage alloc] initWithCGImage:cgPatImage
size:NSZeroSize];
NSColor* patternColor= [NSColor colorWithPatternImage:nsPatImage];
[patternColor setFill];
[bezierPath fill];
Works like a charm in the graphic context of NSView and print nothing in a
print context.
I suspect this has something to do with the notion of « Current context » , as
the context in NSView is explicitly the « currentContext »
But not sure if the printing context is the « current one » in the usual
print sequence ;
err= PMSessionBeginPageNoDialog(printSession, format )
ctx = PMSessionGetCGGraphicsContext(printSession, &ctx)
[myDrawMethode: ctx] // [finalString drawInRect:textBox
withAttributes:attributes]; draws nothing in the printing context
PMSessionEndPageNoDialog(printSession);
I would appreciate any advice or suggestion regarding these points
King regards
