Python Ghostscript Pdf To Png

I am working on a script that will generate a succession of images drawn using the python. Convert EPS images to JPG using Pillow. Adding ghostscript but. Interface to the Ghostscript C-API, both high- and low-level, based on ctypes. Wo Mic Client. Ghostscript is a well known interpreter for the PostScript language and for PDF.

So the state I'm in released a bunch of data in PDF form, but to make matters worse, most (all?) of the PDFs appear to be letters typed in Office, printed/fax, and then scanned (our government at its best eh?). At first I thought I was crazy, but then I started seeing numerous pdfs that are 'tilted', like someone didn't get them on the scanner properly. So, I figured the next best thing to getting the actual text out of them, would be to turn each page into an image.

Obviously this needs to be automated, and I'd prefer to stick with Python if possible. If Ruby or Perl have some form of implementation that's just too awesome to pass up, I can go that route. I've tried pyPDF for text extraction, that obviously didn't do me much good. I've tried swftools, but the images I'm getting from that are just shy of completely unusable. It just seems like the fonts get ruined in the conversion. I also don't even really care about the image format on the way out, just as long as they're relatively lightweight, and readable. Before you do that, contact the.gov entity that produces the files.

You may very well be able to get easy access to that actual digital files. Having worked in.gov and ran into that same problem, it's usually due to antiquated legal requirements (paper signatures) and/or a lack of technical understanding (often, this stuff will bypass IT/web team where they would be able to catch it). You can also call them out on the accessibility issue as a giant JPG of a page is completely inaccessible to assistive technology. – Jan 4 '10 at 20:43 •. If the PDFs are truly scanned images, then you shouldn't convert the PDF to an image, you should extract the image from the PDF.

Most likely, all of the data in the PDF is essentially one giant image, wrapped in PDF verbosity to make it readable in Acrobat. You should try the simple expedient of simply finding the image in the PDF, and copying the bytes out:. The code there is dead simple, and there are probably dozens of reasons it won't work on your PDF files.

But if it does, you'll have a quick and painless way to get the image data out of the PDF files. Here's an alternative approach to turning a.pdf file into images: Use an image printer.

I've successfully used the function below to 'print' pdf's to jpeg images with. However, there are MANY image printers out there. Pick the one you like. Some of the code may need to be altered slightly based on the image printer you pick and the standard file saving format that image printer uses.
