Topic: image xobject in a form xobject - help please?

hi all

i'm working out some functionality in a PDF generator app i'm writing and i need some help.

i'm trying to add images to the documents; simple enough, and i have it working with a single instance of each image. however, i'd like to go the form xobject route to re-use an image and, well, i just can't make it happen.

PDFs i've exported from various apps, using a single image multiple times in the same doc, actually places multiple image xobjects in the documents - not a form xobject. :-(

the PDF spec docs (even the 1.6 version) only show simple vector drawing in a form xobject example.

i've tried various methods based on vague information found by googling, but nothing seems to work. i always get the dreaded "cannot find the XObject 'image1'"...

i'd relly just like to see an example of an image being used in this manner. (again, for clarity, an image [a HEX encoded JPG to be specific] used in a form xobject)

thoughts? examples?

thanks in advance!

cheers
g.
