Re: CGPDFPageGetDrawingTransform refuses to upscale

Derek,

This was, as sometimes happens, an historical decision that "seemed right at the time." This function was originally used for easy layout in N-up printing. In that case, it seemed better to avoid scaling up a PDF file when it was smaller than the page rect - instead, we kept the size unchanged and centered the PDF in the page rect. Unfortunately, this particular behavior now makes it necessary to jump through some hoops if you want uniform scaling both up and down.

And, probably those hoops are simple for you as you must be using transformations all the time, but I have been puzzling on this now for some time and cannot seem to figure out how to do this correctly. I can scale easily, but then my image also needs to be translated to keep it within my rectangle (if I just scale, it walks out of my rect as I make the rect bigger and bigger). What would be the correct way to do the upscaling taking into account the image's art box and the rect I want to display it in?

Thanks,

david.
