Thanks RP...but...I meant whole image as in full size, not scaling.

I need to be more clear... My hopes were that this would allow me to 
save my Full Size images in a Full Size PDF file. This appears to be 
illusion... one can only scale it to fit, or not. I do not want to 
scale the image, that's only helpful if wanting to print it, and I 
already have autosizing/auto-cropping code in place, per user choice.

I need the exported image to remain its full size, so when somebody 
opens it up in Preview of my app afterward, they have the whole image 
again, not a scaled-to-page size new thing....if setting scale, then 
one just gets a larger or smaller image..if smaller, you see the whole 
thing...but you've lost all the pixels. If you scale larger, you get a 
portion of the image.

I guess to save an image as a PDF in full size, and to use the format 
for such, one has to avoid the print manager which operates in PageRect 
land (and no way to set that to the actual image size?) and write the 
raw format per Adobe specifications, there doesn't seem to be a 
Quicktime route for this yet?

I need whatever Apple is doing when it saves a screenshot at full size, 
to PDF, and I guess you can't take an image like that, and re-export it 
out as PDF and still have it be the same size via print manager.
