Hi, I added a new primitive to fetch the BBox of a pdf image. sources and djgpp binaries updated at pdftex.sarovar.org Thanh

From README:

[...] - extensions for pdf inclusion: - added \pdfpagebox as the default setting for pagebox specification. Value specified to individual use of \pdfximage will override this setting. When set to 0 CropBox will be used as default. Example: ,-------- | \pdfpagebox=1 % use MediaBox as default | \pdfximage {f.pdf} % use MediaBox | \pdfximage cropbox {f2.pdf} % use CropBox `-------- - added \pdfximagebbox to fetch the BBox of a pdf image. The BBox is taken from the pagebox associated with the image. Example: ,-------- | \pdfximage {f.pdf} % CropBox will be use by default | \dimen1=\pdfximagebbox\pdflastximage 1 % fetch x1 from CropBox | \dimen2=\pdfximagebbox\pdflastximage 2 % fetch y1 from CropBox | \dimen3=\pdfximagebbox\pdflastximage 3 % fetch x2 from CropBox | \dimen4=\pdfximagebbox\pdflastximage 4 % fetch y2 from CropBox `--------
