Amazing the amount of information on the web. Wasn't what I was looking for, but very nice site. Take care. Hi, just stopped by doing some research for my Nikon website.

]]> Comment on Drawing a round rect with Quartz by boogleTron http://www.dpompa.com/blog/code/drawing-a-round-rect-with-quartz/comment-page-1#comment-8 boogleTron Wed, 09 Dec 2009 00:26:58 +0000 http://www.dpompa.com/blog/?p=22#comment-8 It seems like you forgot to update the posted code after fixing the bug you mentioned. Here's my correction: void DPContextAddRoundRect(CGContextRef context, CGRect rect, CGFloat cornerRad) { // Top Left CGContextMoveToPoint(context, rect.origin.x, cornerRad+rect.origin.y); CGContextAddArcToPoint(context, rect.origin.x, rect.origin.y, rect.origin.x + cornerRad, rect.origin.y, cornerRad); // Top right CGContextAddArcToPoint(context, rect.origin.x + rect.size.width, rect.origin.y, rect.origin.x + rect.size.width, rect.origin.y + cornerRad, cornerRad); It seems like you forgot to update the posted code after fixing the bug you mentioned. Here’s my correction:
void DPContextAddRoundRect(CGContextRef context, CGRect rect, CGFloat cornerRad) {
// Top Left
CGContextMoveToPoint(context, rect.origin.x, cornerRad+rect.origin.y);
CGContextAddArcToPoint(context,
rect.origin.x,
rect.origin.y,
rect.origin.x + cornerRad,
rect.origin.y,
cornerRad);
// Top right
CGContextAddArcToPoint(context,
rect.origin.x + rect.size.width,
rect.origin.y,
rect.origin.x + rect.size.width,
rect.origin.y + cornerRad,
cornerRad);

I'm a quartz drawing noob and the thing that I had to figure out on my own was that I needed to bracket the call to your function like so: CGContextBeginPath(context); DPContextAddRoundRect(context, rect, radius); CGContextDrawPath(context, kCGPathStroke); Thanks for the hint! I’m a quartz drawing noob and the thing that I had to figure out on my own was that I needed to bracket the call to your function like so:

This is just a function I hacked up when I noticed the blurred drawing. I actually discovered about CGRectIntegral() slightly later, and recommend using that. You’re absolutely right.

This code could move the right and bottom edges by up to a whole pixel, but it would never move the left or top edges by more than half a pixel. That is a strange bias to have. Finally, there’s a lot of potentially costly type conversion going on: first from double to long double, and then from long to double. Using rint() (and rintf() for 32-bit) would avoid that. Using round() and roundf() would also avoid the dependency on the prevailing rounding mode. I am not sure how this is better than CGRectIntegral().
