Dear programmers,
I am hoping that the list can help me solve what I assume are 3 simple issues. I am starting to explore the murky details of working with images.
1. I have an NSImageView which scales the image to fit, aligned centered. My question is, how do I find the NSRect of the image in the image view (as it does not fill the frame)?
2. Also, I used Apples Cropped Image sample code to create a selection rectangle, but when I resize the frame the rectangle does not resize with it. Do I need to do some sort of NSAffineTransform for that to happen
3. The selection rectangles need to be saved in a format that is scale of nsimageview independent, i.e., whenever someone opens this image they should be able to see the selection view over X portion of the image immaterial of the size of the image. I am assuming that I need to use image size to create some absolute transformation of the selection rectangle and convert back and forth...
Ideas? Help? Thanks in advance,
Matthew
