PDFTrick - PDF image extraction

[webfork]

Cross-platform tool for pulling images out of PDF files. I was annoyed that this didn't just rip all the images out of a given doc, but I was pleased how it seemed to work better than a lot of other PDF image tools I've tested. Additionally, the preview function is quite sharp.

License: GPLv3

Requires: Java

Portable: Yes, writes no settings

Stealth: No: writes a DLL and log file to \USER\.pdftrick\. Negavitely, the DLL (libpdftrick_native_1.5_64.dll) file is somewhat big for a temp file: 9.7 megs.

Wishlist:

* Some explanation of what "clean" does
* Stealth status, auto-delete the .DLL file
* Batch mode of some kind both for all the image file and for multiple images
* Support drag-and-drop

I don't want to be alarmist but I think the program may contain a PUP.

I tried to examine the program in my Sandbox.
There was mention of third party software (which I stated I did not want) but my AntiVirus (MBAM) did indeed block a PUP.
This was during an installation; I decided not to run the actual program

If this was all I would not bother with a comment but I subsequently encountered a few problems.
Of course this might have been coincidental.

Apologies!!! mea culpa!

The virustotal results were so convincing that I went back to the drawing board; I had confused this program with another I was looking at around the same time (not from TPFC)

I would have deleted my contribution but then smaragdus's comment wouldn't have made much sense.

No problem.  Better to check and the forums is the place to iron this stuff out.  I was for a short time including VirusTotal and other hash checks as a part of any individual post.  I might start doing that again.

V 1.2 is out with some nice changes, my favorite one bolded below:

• lots of bugs fixed
  stability improved
  performance improved
  better support for inline images added
  resizable interface

I ran some tests today and again I'm impressed: it matched PDF Nitro for pulling inline images out of a PDF. Neither PDF-XChange nor Foxit will do that and I'd be surprised if the free version of Adobe Acrobat has that capability. It also converted PDFs that were really just huge images to their original resolution (PDF-XChange can do this but asks you to set the resolution).

Still portable, writing to \USER\.pdftrick\ saving no settings.


Edit:

I did a bit more testing with various other types of scans with some mixed results. On one picture with lots of color blobs (an art piece) it tried to separate the individual blobs. When I tried to extract the whole image, it worked but with some areas that looked blocky and compressed.

Ultimately it's still great freeware but I think PDF-XChange might be the best route for reliable extraction of multiple files. NitroPDF (commercial) also does a good job.
