The script will output all images found, even repeated ones. If a supported image has an associated image mask defined, it will automatically be used to create a transparent image.

Since HexaPDF doesn't currently support writing all types of PDF images, you might get some error messages for those that can't be written. It will iterate over all pages of the input document provided on the command line and create files using your file naming scheme. Processor = ImageBorderProcessor.new(page, index) # If the image is rotated, you will need all 4 coordinates, nut just the 2įilename = rescue puts "Can write image += 1ĭoc.pages.each_with_index do |page, index| I don't have a solution in Python but here is a small script using Ruby and HexaPDF: require 'hexapdf'Ĭlass ImageBorderProcessor < HexaPDF::Content::Processor
Again it is easy in a single command line to see which pages are referenced by a group of images, but to see which image is placed where requires analyzing each pages resources, again requiring a library interrogation of page contents, thus best done via power house libraries such as iText or any other like PDFtron for python. Your related part question was knowing where those components are placed on each page since one image (and its alpha mask) could be placed multiple times such as a heading logo on each page. So PDFbox is one of the simpler/better tools for blending to a suitable output, (as you have discovered) but for Python it is generally the top end library products that can identify the placement of the two images and combine into a suitable alpha output like a new PNG.įor many suggestions see Extract images from PDF without resampling, in python?. It is not trivial to overlay the mask on the RGB component when simply extracted but can allow for colour changes if desired. Note that a raw PNG (whatever its source common resolution was) will retain number of dots but its scale when inserted into the PDF could be totally different horizontal and vertical, thus the only meaningful data is W x H in pixel values. What you may note is that the objects that were inserted most likely as one PNG are broken in two when injected into the PDF and their scaled placement is defined. The Greyscale Alpha softmask (B&W) transparency components are not necessarily tied direct to a page or an image other than by internal references, and usually appear like negatives. Here the individual object references have been converted into normal tiff or jpg (other tools may use pbm and pgm especially for OCR but the result is generally similar). Here we can see a visual layout of all the compressed images in the file by using one command line to extract images.
Python tools are likely to have similar problems to any tools even those that require a single line to manipulate images or extract their details.
