PDFrasterFarian Development Thread

Editor's Note: These files have been blocked from being downloaded because it has been brought to our attention that the application as it currently exists includes an expired trial version of commercial software.


The latest version can be found here:


This is a sister thread to this one. I'm posting the beta here to get feedback before putting up the full version on the other thread. Please don't be shy about any comments, suggestions, or frank explanations about how it's all crap.

+Much better boldness enhancement (see pics in other thread)
+Quarters-of-a-page mode for even more readability
+UI overhaul
+Multithreading/multicore support
+Big speed improvement (...not really saying much...)
+Customizable defaults
+Better text quality using 'simple' processing
+No need for password stripping

Known issues:
+Currently, AutoImager must be installed for the new image enhancement to work. A copy of the installer is attached.
+Incompatible with some filename characters ( ')' and '&' )
+When autocropping, the original cropbox is ignored. If something is revealed that was hidden, autocropping will include it leading to a larger page than with autocropping disabled.
+Lastly, the color-reduction step doesn't quite output grayscale values 0, 85, 170, 255. Instead, it produces four palletized colors which merely come close. The Reader reinterprets these and the result sometimes is white backgrounds with slight dithering and (possibly) a slight reduction in text quality.

Todo (short and long term):
One-click profiles
Promptless batch operation
Support for rendering djvu and other formats
Somehow increase text weight at the PDF level not as an image filter
Ability to run several pdfrasterfarian instances at once
Improve performance (currently... 4 to 15 minutes per 100 pages on my 1-core athlon 64)
Make a gui (with manual cropping, and zoom fragments)

Suggestions on fixing any of these or other issues are, of course, greatly appreciated. (Note to the hackers: the image-processing steps are all neatly isolated in the kernel-*.cmd files.)
