colorblind_pdf is a tool designed to test the accessibility of PDF documents for individuals with color vision deficiencies. It processes PDFs to simulate how the contained images would appear to someone with various types of color vision deficiencies, such as deuteranopia, protanopia, and tritanopia.
To install colorblind_pdf, use pipx for an isolated installation:
pipx install colorblind_pdfTo use colorblind_pdf, provide the path to the PDF you want to process, the output directory, and specify the type of color deficiency simulation. For example:
Most simple way:
colorblind_pdf my_document.pdf-o/--output_dir: current directory ('.')
-d/--deficiency_type: all deficiencies ('all')
-D/--dpi: resolution (default: 150 DPI)
--merge: merge the outputs into a single file where each page is a mosaic
-O/--overlay: merged output will get an overlay over the subpages
The test.pdf with merged, overlayed output should look like this:
