Then use "save as..." to save a cropped copy.

Thanks for the info. Although I am a long time mac user I didn't know that. I am trying it now, but it is taking so long that the file will probably be way too large. I am working with Google and Internet Archive pdfs.

pdfhelpers

Try my 'pdfhelpers' scripts. This is my first work in Python, but it do all what i need to do with PDFs.

pdfsort - groups pdfs by formats (input and output paths are in pdfhelpers.conf)
pdfcrop <directory_with_pdfs_to_crop> - crops white margins

Depends on Python 2.6.x, PyPDF 1.12, GPL Ghostscript 8.xx, pdftk 1.41

See pdfhelpers.conf for options.

This would be a whole lot easier and automatic if the PDF viewer has an option to zoom to fit visible, thus ignoring the white spaces. Are there any PDF viewers with this option? A tolerance slider would be nice so it can ignore the page number in the corner.

The irex delta chip, when rendering the screen, should know exactly where the white spaces are... they should consider adding some sort of auto-zoom mode for the rendering pipeline.
