Hi all,
I'm trying to create a QTMovie from PDF data. The movie will scroll
down the PDF at a set speed with a set frame height. The only trouble
I'm having is at the end of creating the movie the first frame is
drawn in the upper-left hand corner of my screen. I'm compositing each
image just before adding it to the movie, if I use a file from disk
the odd behavior described above doesn't occur. Why is that???
Any thoughts and suggestions are welcome, this is a real stumper.
Peace, Alan
Here is my code:
for (i = 0; i <= numFrames; i++)
{
NSLog(@"i = %i", i);
//NSImage *frame = [[NSImage alloc] initWithContentsOfFile: path
to a file];
NSImage *frame = [[NSImage alloc] initWithSize: frameSize];
rect = NSMakeRect(0.0, imageYOrigin, frameSize.width,
frameSize.height);
[frame lockFocus];
[masterImage compositeToPoint: NSMakePoint(0, 0) fromRect: rect
operation: NSCompositeCopy];
[frame unlockFocus];
[movie addImage: frame forDuration: curTime withAttributes:
imageCompression];
NSLog(@"Added image");
[frame release];
imageYOrigin -= currentSpeed;
}
