Imagine my frustration in those few instances when I forgot to select the option to print in reverse order when printing the even-numbered pages and ruined a long print job. If I'm printing a four-page document, printing the even-numbered pages in reverse order means page 4 prints on the back of page 3 and page 2 prints on the back of page 1. Regardless of how I print, the overall process is to print the odd-numbered pages, reload the stack of printed pages into the paper tray, then print the even-numbered pages in reverse order. If you want to know the best settings (most settings will be fine anyway) you can clone the project and run python tests.py to get timings.PNG format is pretty slow, this is because of the compression.If i/o is your bottleneck, using the JPEG format can lead to significant gains.Using multiple threads can give you some gains but avoid more than 4 as this will cause i/o bottleneck (even on my NVMe SSD!).Otherwise i/o usually becomes the bottleneck. Using an output folder is significantly faster if you are using an SSD.Allow the user to specify poppler's installation path with poppler_path.single_file parameter allows you to convert the first PDF page only, without adding digits at the end of the output_file.grayscale parameter allows you to convert images to grayscale ( -gray in pdftoppm CLI).size=(500, 500) will resize the image to 500x500 pixels, not preserving aspect ratio.size=(400, None) will make the image 400 pixels wide, preserving aspect ratio.size=400 will fit the image to a 400x400 box, preserving aspect ratio.size parameter allows you to define the shape of the resulting images ( -scale-to in pdftoppm CLI).paths_only parameter will return image paths instead of Image objects, to prevent OOM when converting a big PDF.jpegopt parameter allows for tuning of the output JPEG when using fmt="jpeg" ( -jpegopt in pdftoppm CLI) (Thank you pdfinfo_from_path and pdfinfo_from_bytes which expose the output of the pdfinfo CLI.Fixed a bug where using pdf2image with multiple threads (but not multiple processes) would cause and exception.Add use_pdftocairo parameter which forces pdf2image to use pdftocairo.Allow users to hide attributes when using pdftoppm with hide_attributes (Thank you Fix console opening on Windows (Thank you Add timeout parameter which raises PDFPopplerTimeoutError after the given number of seconds.Images will be a list of PIL Image representing each page of the PDF document.Ĭonvert_from_path(pdf_path, dpi=200, output_folder=None, first_page=None, last_page=None, fmt='ppm', jpegopt=None, thread_count=1, userpw=None, use_cropbox=False, strict=False, transparent=False, single_file=False, output_file=str(uuid.uuid4()), poppler_path=None, grayscale=False, size=None, paths_only=False, use_pdftocairo=False, timeout=600)Ĭonvert_from_bytes(pdf_file, dpi=200, output_folder=None, first_page=None, last_page=None, fmt='ppm', jpegopt=None, thread_count=1, userpw=None, use_cropbox=False, strict=False, transparent=False, single_file=False, output_file=str(uuid.uuid4()), poppler_path=None, grayscale=False, size=None, paths_only=False, use_pdftocairo=False, timeout=600) What's new? TemporaryDirectory () as path : images_from_path = convert_from_path ( '/home/belval/example.pdf', output_folder = path ) # Do something here OR better yet import tempfile with tempfile. OR images = convert_from_bytes ( open ( '/home/belval/example.pdf', 'rb' ). Then simply do: images = convert_from_path ( '/home/belval/example.pdf' ) Install pdf2image: pip install pdf2imageįrom pdf2image import convert_from_path, convert_from_bytes from pdf2image.exceptions import ( PDFInfoNotInstalledError, PDFPageCountError, PDFSynta圎rror ).Install poppler: conda install -c conda-forge poppler.If they are not installed, refer to your package manager to install poppler-utils Platform-independant (Using conda) Most distros ship with pdftoppm and pdftocairo. Mac users will have to install poppler for Mac. You will then have to add the bin/ folder to PATH or use poppler_path = r"C:\path\to\poppler-xx\bin" as an argument in convert_from_path. I recommend version which is the most up-to-date. Windows users will have to build or download poppler for Windows. A python (3.6+) module that wraps pdftoppm and pdftocairo to convert PDF to a PIL Image object How to install
