Hello all,
I am developing a mapping application where I need to draw labels in a
view. Currently I am using (as a first approach)
[_name drawAtPoint:labelPoint withAttributes:nil];
This works: However, it does not exactly has the desired effect, since
the labels are always drawn horizontally. The labels are actually
street names and the streets are drawn with NSBezierPath stroke.
Ideally I would like the street label to be exactly drawn on the
NSBezierPath which is a connected list of points, but at least to be
drawn with the same angle as the NSBezierPath segment. There is this
NSBezierPath
- (void)appendBezierPathWithGlyphs:(NSGlyph *)glyphs count:(int)count
inFont:(NSFont *)fontObj
method that might be of interest in conjunction with
NSBezierPath *bezierPath = [NSBezierPath bezierPath];
NSAffineTransform *transform = [NSAffineTransform transform];
[bezierPath moveToPoint: NSMakePoint(0.0, 0.0)];
[bezierPath lineToPoint: NSMakePoint(100.0, 100.0)];
[transform translateXBy: 10.0 yBy: 10.0];
[bezierPath transformUsingAffineTransform: transform];
but this means to manually find the glyphs for each character in the
label ([NSFont glyphWithName:]). This probably works on MacOSX, but
does it also work under GNUstep? I am wondering if there is even an
easier approach for accomplishing this!?
Hints are greatly appreciated!
Thanks,
Andreas
