Hi,
I'm trying to generate a new image that is made up of a combination of
other images.
As I iterate over the array holding the images I want to do is...
- place the componant image in the new canvas at a certain point
(150,187)
- rotate the componant image by a certain value (calculated previously)
I don't mind how the image fits in the new canvas, it doesn't have to
be completely within it.
I think I need to use NSAffineTransform?
I was using drawinrect previously for non-rotated movement.
Do I need to draw the componant image to the canvas first then rotate
it?
The code I have at the moment is
[code]
//calc rotation
double rotation = 360 / ki;
double rotateby = rotation;
//set coordinates to x,y -> 150,187 to start
float x = 150;
float y = 187;
//for each image
NSEnumerator *imageLoop = [kitImages objectEnumerator];
NSString *imgPath;
while ((imgPath = [imageLoop nextObject])) {
NSImage *img = [[NSImage
alloc]initWithContentsOfFile:imgPath];
//rotate image
//apply image to view
[targetImage lockFocus];
//[img drawInRect:NSMakeRect(x,y,xb,yb)
fromRect:NSMakeRect(150,150,0,0) operation:NSCompositeCopy fraction:1];
//set new rotation
rotation = rotation+rotateby;
[/code]
I've tried looking at some of the samples, but they seem to be cover
rotating in place and resizing which is more complicated than I'm
looking for. I'm expecting to effectively have the componant images
fan out on the canvas.
If anyone could help me with the process I'd be grateful, do I have to
create a intermediary image to make the rotated image square?
Thanks,
Amy
Many Thanks
