Re: How to make a CALayer dont get blur when rotating.
Have you tried to add the following line?
[nLayer setValue:[NSNumber numberWithFloat:.]
forKeyPath:@transform.scale];

Hello well finally I manage to rotate the CALayer each time I click
on it. what I did was the following:
-(void)mouseDown:(NSEvent *)event
{
[event retain];
[mouseDownEvent release];
mouseDownEvent = event;
NSPoint p2 = [event locationInWindow];
NSPoint p3 = [self convertPoint:p2 fromView:nil];
CGPoint p = NSPointToCGPoint(p3);
CALayer * nLayer = [_gameboardLayer hitTest:p];
if (nLayer.name != nil) {
NSNumber* value = [NSNumber numberWithFloat:PERP()];
value = [NSNumber numberWithFloat:[value floatValue] + [[nLayer
valueForKeyPath:@transform.rotation.z] floatValue]];
[nLayer setValue:value forKeyPath:@transform.rotation.z];
}
}
#define PERP () (90 * M_PI / 180)
but I realize that each time the images its perpendicular its kinda
blurry I dunno how to rotate the layer without loosing quality.
the contents of the layer its .png
Thanks

Re: How to make a CALayer dont get blur when rotating.
There are some bugs in CALayer that will give you blurred images. But
you have to tell us more about your layer hierarchy and what kind of
transformations you have on the different layers?
Have you tried to rotate your layer in a simple test application?
Have you tried to use another image?

Re: DICOM images in Cocoa
Try this: http://www.osirix-viewer.com/ 13 aug 2008 kl. 08.12 skrev Devraj Mukherjee: Hi all, My application requires to display DICOM image files. Preview doesn't support DICOM by nature so the thought at the moment is to use something like ImageMagick and convert these images to something JPEG on the fly? NSImage doesn't seem to be able to take a DICOM stream. Is this the best of doing this? Does anyone know of a Cocoa DICOM reader library?
