Assemblage de PDF numérisés à partir de 2 dossiers

Cherchez-vous le programme d'ImageMagick ? montage ? ImageMagick peut travailler sur les pdf.

Si vous voulez quelque chose de plus flexible que le montage ImageMagick, vous pouvez aussi écrire un simple script en Python langue avec pyPdf pyPdf peut fusionner des pages PDF et appliquer des transformations de base (par exemple, translation, rotation, mise à l'échelle). Exemple script :

import pyPdf

def merge_horizontal(out_filename, left_filename, right_filename):
    """ Merge the first page of two PDFs side-to-side """

    # open the PDF files to be merged
    with open(left_filename) as left_file, open(right_filename) as right_file, open(out_filename, 'w') as output_file:
        left_pdf = pyPdf.PdfFileReader(left_file)
        right_pdf = pyPdf.PdfFileReader(right_file)
        output = pyPdf.PdfFileWriter()

        # get the first page from each pdf
        left_page = left_pdf.pages[0]
        right_page = right_pdf.pages[0]

        # start a new blank page with a size that can fit the merged pages side by side
        page = output.addBlankPage(
            width=left_page.mediaBox.getWidth() + right_page.mediaBox.getWidth(),
            height=max(left_page.mediaBox.getHeight(), right_page.mediaBox.getHeight()),
        )

        # draw the pages on that new page
        page.mergeTranslatedPage(left_page, 0, 0)
        page.mergeTranslatedPage(right_page, left_page.mediaBox.getWidth(), 0)

        # write to file
        output.write(output_file)

def mkdir_p(path):
    try:
        os.makedirs(path)
    except OSError as exc:
        if not (exc.errno == errno.EEXIST and os.path.isdir(path)): 
            raise
if __name__ == '__main__':
    import sys, os, errno
    output_folder_name = sys.argv[1]
    left_folder_name = sys.argv[2]
    right_folder_name = sys.argv[3]
    left_files = set(os.listdir(left_folder_name))
    right_files = set(os.listdir(right_folder_name))
    mkdir_p(output_folder_name)

    # for every files that are in both left_files and right_files
    for f in left_files.intersection(right_files):
        output_file_name = os.path.join(output_folder_name, f)
        left_file_name = os.path.join(left_folder_name, f)
        right_file_name = os.path.join(right_folder_name, f)
        print 'merging %s and %s into %s' % (left_file_name, right_file_name, output_file_name)
        merge_horizontal(output_file_name, left_file_name, right_file_name)

    # pair is missing, not merging
    print 'Only in left folder: ', left_files - right_files
    print 'Only in right folder: ', right_files - left_files

Et appelez le script comme suit :

python merge.py output_folder left_folder right_folder

Exemple de sortie :

merging folderA/two.pdf and folderB/two.pdf into output/dacd/adca/two.pdf
merging folderA/one.pdf and folderB/one.pdf into output/dacd/adca/one.pdf
merging folderA/three.pdf and folderB/three.pdf into output/dacd/adca/three.pdf
Only in left folder:  set(['four.pdf'])
Only in right folder:  set(['five.pdf'])
