Actually, I have one idea why this happens.
Maybe because usually width=8, height = 14 so [self bounds] returns
NSRect(0,0,8.64,14.64). And
maxScanArea = NSRect(0.32, 0.32, 8, 14). So there can be some
approximation to integer value, not float.
But it it is true, how to deal with this?

Hi Alexander,
Your code will draw the image in maxScanArea. You should probably
look for a bug elsewhere.
I like to replace complex drawing with simple color fills when
debugging drawing location issues. At least it limits what could go
wrong.

Hello
I have custom NSView, and want to draw whole NSImage inside some
custom
rectangular area of NSView.
I tried to use [NSImage drawInRect:...] but result does not fit
desired
rectangular area of NSView.
My code:
- (void) setPreviewWidth:(float)width height:(float)height
{
margin = width / 25;
maxScanArea = NSMakeRect(margin, margin, width, height);
canvasArea = NSMakeRect(0, 0, width + 2.0 * margin, height +
2.0 *
margin);
[self setBounds:canvasArea];
}
- (void) drawRect:(NSRect)rect
{
// Drawing image in preview
if (image) {
NSRect imageRect;
imageRect.origin = NSZeroPoint;
imageRect.size = [image size];
[image drawInRect:maxScanArea
fromRect:imageRect
operation:NSCompositeSourceOver
fraction:1];
// I want image to be drawn in maxScanArea rect, but
it is
drawn in [self bounds] rect.
}
}
Could you advise how can I draw exactly inside maxScanArea NSRect
in NSView?
BR, Alexander.
