Hello,
Well i've been struggling with this for quite a while and would
appreciate if anyone could point me in the right direction.
I am trying to implement a custom NSTypesetter, to start with i just
want to lay 2 characters, an "A" and an inline image, thats it.
The character "A" gets drawn properly, but there is some problem with
the inLine image. I see a small square besides the inLine image.
Here is what i am doing in my custom NSTypesetter class, which i have
hard coded to draw just the two glyphs:
- (NSUInteger)layoutParagraphAtPoint:(NSPointPointer)lineFragmentOrigin
{
// Begin para
[self beginParagraph];
// Begin Line
[self beginLineWithGlyphAtIndex:0];
// Start at 0,0 (the size of the inLine image is (53, 57))
NSRect r = NSMakeRect(0, 0, 100, 57);
NSPoint loc = NSMakePoint(0, 0);
// Set the line fragment rectangle for the entire glyph range
[super setLineFragmentRect:r forGlyphRange:NSMakeRange(0, 2)
usedRect:r baselineOffset:57];
// Set the location for "A"
[super setLocation:loc withAdvancements:0
forStartOfGlyphRange:NSMakeRange(0, 1)];
// Set the attachment size for the inLine image
[super setAttachmentSize:NSMakeSize(53, 57)
forGlyphRange:NSMakeRange(1, 1)];
// Position the image a bit further on the right of "A"
loc = NSMakePoint(21, 0);
[super setLocation:loc withAdvancements:0
forStartOfGlyphRange:NSMakeRange(1, 1)];
// End line
[self endLineWithGlyphRange:NSMakeRange(0, 2)];
// End para
[self endParagraph];
return 2;
}
Thanks,
Chaitanya
