Well I have been struggling with this for many weeks, many of these answers helped me through, but there was always something missing, apparently no one here has ever had problems with jbig2 encoded images. More that you can do with images, including replacing them in the PDF file. Wrote /Im10 32x32 /FlateDecode 36B /ICCBased to Which can print something like Wrote /Im1 150x150 /DCTDecode 5,952B /ICCBased to Print ("Failed to read image with PIL: ") Pdf_in = PdfFileReader(open(pdf_fp, "rb")) Zlib_compressed = '/FlateDecode' in sub_obj.get('/Filter', '') Images += get_object_images(sub_obj.getObject()) If '/Resources' in sub_obj and '/XObject' in sub_obj: If isinstance(cspace, generic.ArrayObject) and cspace = '/ICCBased':Ĭolor_map = obj.getObject() #!/usr/bin/env python3įrom PyPDF2 import PdfFileReader, generic I also found that sometimes image in PDF may be compressed by zlib, so my code supports decompression. Here is my version from 2019 that recursively gets all images from PDF and reads them with PIL.Ĭompatible with Python 2/3. # im = Image.open(io.BytesIO(tiff_header + data)) Tiff_header = tiff_header_for_CCITT(width, height, img_size, CCITT_group) If xObject = -1:ĭata = xObject._data # sorry, getData() does not work for CCITTFaxDecode Tiff_header_struct = ' 0 - Mixed one- and two-dimensional encoding (Group 3, 2-D) net: ĭef tiff_header_for_CCITT(width, height, img_size, CCITT_group=4): In Python with PyPDF2 for CCITTFaxDecode filter: import PyPDF2Įxtract images coded with CCITTFaxDecode in. If x_object = "/FlateDecode":Įlif x_object = "/DCTDecode":Įlif x_object = "/JPXDecode": In Python with PyPDF2 and Pillow libraries it is simple: PyPDF2>=2.10.0 from PyPDF2 import PdfReader Pix.save(os.path.join(workdir, "%s_p%s-%s.png" % (each_path, i, xref))) Import fitz # pip install -upgrade pip pip install -upgrade pymupdfĭoc = fitz.Document((os.path.join(workdir, each_path)))įor i in tqdm(range(len(doc)), desc="pages"):įor img in tqdm(doc.get_page_images(i), desc="page_images"): Here is a modified the version for fitz 1.19.6: import os png files, but worked out of the box and is fast.
