Update: PeasyP2J has now been incorporated into PeasyPDF.

Exprimo is using ghostscript 8.71. Current version is 9.05.


command line way (for whole doc, leave out FirstPage/LastPage):

G'day rcrsn51,

A nice utility.

Using Slacko-5.3.3 as-was, converted OK a pdf made by CUPS-PDF and pages from a printer manual taken off the manufacturer's CD-ROM.
But then had a failure to get jpgs from a downloaded pdf manual for an espresso coffee machine.
So I downloaded the new ghostscript version you provided the link to, installed this into Slacko-5.3.3, and PeasyP2J now works with this pdf as well.

Changing the dpi and re-doing the same page gave no warning about over-writing the original jpg file, but as it all works so quickly, such a warning is probably unnecessary - just do it again until I'm happy with the image, or manually rename the previous file if I need to keep it as well.

Thanks for the pet,

David S.

Thanks for testing this.

Dear puppians,

Here is a variation that produces png files and can handle transparency. If rcrsn51 wants to add it to his little gem of a program, fine, otherwise it also works standalone.

With kind regards,

Excellent! I have packaged your PNG features as a separate PET based on my cleaned-up version 1.2. Could you give it some tests? The transparency option appears to be working.

Why limit it to one page? It would be trivial to let it include any or no limiter (eg, 4-7) for page selection.

While that feature is certainly possible, I can't see the practical value. I believe that people would use this program to extract a single interesting image from a PDF document. I can't envision a scenario where I would want to turn an entire PDF into single JPEGs.

See the discussion here.

I suppose something like converting a few pages of graphs for posting to a forum or loading as pix on a device (cellphone, etc, vs loading a pdf reader) might be useful.

Oh, OK.

See the new instructions above for entering a list of pages.

works nicely, thanks. To be traditional, you could include a page span with "-" , and separate pages with "," (or you can just leave it the way it is (might as well use ghostscript's Firstpage/LastPage function)

Version that adds page span; ex: 4-7

Thanks for this it works great

One thing I did notice is that the pdf source file needs to contain no spaces in its title overwise you fails to work.

Fixed! See Version 1.3. Please test and report.

I have also included the code for selecting ranges.

Thanks again for the update and great work

A simple idea but so useful, stops me having to upload whole documents when I can just send some a page( s ) from a pdf.

As and afterthought had you considered adding a jpeg library to this application eg libjpegturbo that could speed up the compression/decompression process?

http://libjpeg-turbo.virtualgl.org/

libjpeg-turbo is a derivative of libjpeg that uses SIMD instructions (MMX, SSE2, NEON) to accelerate baseline JPEG compression and decompression on x86, x86-64, and ARM systems. On such systems, libjpeg-turbo is generally 2-4x as fast as the unmodified version of libjpeg, all else being equal.

It's just a thought!

Goldberg Variations: (Doesn't post correctly

Edit: converted to png...works!

( format could be an option? )

BTW/ score was posted as freeware

Here's one with the PNG code included:

I've run this beautiful piece of software in Puppy528, Slacko53, Wary53, and Racey53. I used it with ghostscript 8.15, 8.64, 8.71, and 9.05. Everything works fine! Really useful utility for me. Currently installed in all four Puppy variants with ghostscript 8.71.

Thanks for a great tool.

Ghostscript 8.15 is definitely a problem with some PDFs so it's worthwhile to upgrade.

The version of PeasyP2J that is now included in PeasyPDF goes one step further. It can extract some pages from a PDF document and glue them back together into a new PDF.

You can then run the PDF Builder component to add your own pages to the document.

Thanks for testing.

I can see some advantage to first creating a folder of separate pages, so that I can add the new page anywhere I want instead of at the end. I could also remove/edit existing pages. Maybe I'm not seeing something?
