The crop box defines the region to which the contents of the page are to be clipped (cropped) when displayed or printed. Unlike the other boxes, the crop box has no defined meaning in terms of physical page geometry or intended use; it merely imposes clipping on the page contents. However, in the absence of additional information (such as imposition instructions specified in a JDF or PJTF job ticket), the crop box determines how the pages contents are to be positioned on the output medium. The default value is the pages media box. </quote>
Notice the last sentence.
the problem is that "in the beginning of pdf" there were only the mediabox and the cropbox; so, having better defined specs is fine, but we do have to deal with older graphics, and the main thing i have in mind is strategies, so, either we implement something in pdftex, or we need access to the info so that we can implement strategies \pdfgetimagebox artbox|trimbox|cropbox|... {filename} \pdflastimagellx \pdflastimagelly \pdflastimageurx \pdflastimageury (zero when not present) btw, currently a test \setbox0\hbox{\pdfximage \pdfimagepagenumber ArtBox{...}} results in an inclusion; is there a reason why unreferences images are included? i think that even \setbox0\hbox{\pdfximage \pdfimagepagenumber ArtBox{...}\pdfrefximage\pdflastximage} should not lead to an inclusion unless box 0 is flushed ps. ghostscript is unaware of other than media/cropboxes, and artbox and such get lost in conversion; i already filed this as a bug it's a pitty that this kind of stuff was not already sorted out in the pdf 1.1 times Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
