Patches and Windows binaries for the Xpdf toolkit command line utilities (upstream release version 4.05) to enable TIFF output and more, see: https://www.xpdfreader.com
Patch pdftotiff-xpdf-4.05.patch adds alpha channel export capability for pages rendered to bitmap:
- pdftoppm has
-alpha
option which exports the mask (only) as an 8-bit PGM - new tool "pdftotiff" allows export of pages as TIFF files (requires an available libtiff to compile)
- pdftotiff also has
-alpha
option allowing generation of image with mask (to the same file) - pdftotiff and pdftoppm have new
-cmyk
option allowing generation of color separated TIFF files (only if configured with-DSPLASH_CMYK=ON
to cmake) - TIFF output files are compressed by default with LZW (or Huffman-RLE for
-mono
); this can be disabled with option-no-compression
Patch pdfimages-xpdf-4.05.patch allows export of embedded images in more formats (PNG or TIFF):
- pdfimages now has
-png
option to export as PNG files as monochrome, grayscale or color - pdfimages now also has
-tiff
option (when libtiff is available) to export as TIFF files in monochrome, grayscale, color or separated (as they are in the source PDF) - pdfimages can now correctly export indexed color images as RGB (either PNG or TIFF)
- masks are written to separate image files, as either a monochrome or grayscale, PNG or TIFF (this is not ideal, but I'm unsure of how to resolve this)
- specifying
-j
(optionally in addition to either-raw
,-png
or-tiff
) exports embedded JPEG images as.jpg
files with other images in the specified format (PBM if not specified)
