I understand that the W & H given under the stream of an XObject (pertaining to images) is not the size of the image, as it will be displayed when viewing the PDF, my matrix calculations seem to working now, and I can get the location of an image 100% accurate, when matching my calculated coordinates for an image to the coordinates Adobe Illustrator gives for an object (using the info-panel to get the coords.)

My problem is this- the width and height I get back from my matrix-calculations is very near to the width and height reported by AI, but not quite right.

e.g:

I have an image:
the XObject stream says its 768 by 298 (landscape)

Adobe Illustrator says the image object is 2445.152 by 952.839 (so this is the display size)

And my Matrix calculations tell me its suppose to be: 2454.7465 by 952.4927
Matrix printout at time of handling image:
[ 2454.7466, 0.0, 0.0 ]
[ 0.0, 952.4928, 0.0 ]
[ -837.5133, 42.506287, 1.0 ]

Any ideas muuuuchos appreciated!!!!
