On the iPad, I need to render a large pdf (more than 1gb). For this I use Quartz. Now everything works fine except the quality of included pdf in my pdf. An image will explain everything. This is the pdf document: http://dl.dropbox.com/u/5809971/PDFRender/book.pdf This is the ipad rendering (simulator and device are identical): http:...
I have a repeating quartz job that takes a variable amount of time to run. I don't want to have multiple executions of the job running simultaneously. Is there a quartz way to wait for the job to finish before starting it again, or should I just use a static variable in the job to keep track of whether or not the job is running? ...

I've looked around everywhere to no avail. I'm doing some image loading in a thread and since UIKit is not thread safe I'm going to have to store the images as CGImageRefs but I can't figure out how to do this.

Hi there! I'm making a game which requires multiple images to be drawn on the screen. The code I'm using for this is: - (void)drawRect:(CGRect)rect { for (i=1;i<=totalImages;i++) { if (imageExists[i]) { [image drawAtPoint:CGPointmake(imageX[i],imageY[i])]; } } } This drawRect is called by a function: ...
