Мой собственный вклад – обработка /Indexed файлы как таковые: for obj in xObject: if xObject = '/Image': size = (xObject, xObject) color_space = xObject if isinstance(color_space, ) and color_space = '/Indexed': color_space, base, hival, lookup = # pg 262 mode = img_modes if xObject = '/FlateDecode': data = xObject.getData() img = ombytes(mode, size, data) if color_space = '/Indexed': img.putpalette(lookup.getData()) img = img.convert('RGB') img.save('.png'.format(filename_prefix, i))

В Python с PyPDF2 для фильтра CCITTFaxDecode: import PyPDF2 import struct ''' Links: PDF format: CCITT Group 4: !!PDF-E&type=items Extract images from pdf: Extract images coded with CCITTFaxDecode in.
