Coherent PDF Python API Usage Examples

Back to main page

Here are some examples of the Coherent PDF Python API in action. For more instructions, see the Full PDF Manual.

#Merge example
import sys
import pycpdflib

#DLL loading depends on your own platform. These are the author's settings.
if sys.platform.startswith('darwin'):
    pycpdflib.loadDLL("/Users/john/repos/python-libcpdf/libpycpdf.so")
elif sys.platform.startswith('linux'):
    pycpdflib.loadDLL("../libpycpdf.so")
elif sys.platform.startswith('win32') or sys.platform.startswith('cygwin'):
    os.add_dll_directory("C:\\\\OCaml64/home/JohnWhitington/python-libcpdf/")
    pycpdflib.loadDLL("libpycpdf.dll")

#We will take the input hello.pdf and repeat it three times
mergepdf = pycpdflib.fromFile('hello.pdf', '')

#The list of PDFs to merge
pdfs = [mergepdf, mergepdf, mergepdf]

#Merge them
merged = pycpdflib.mergeSimple(pdfs)

#Write output
pycpdflib.toFile(merged, 'merged.pdf', False, False)

Read the file hello.pdf and triplicate it, writing to merged.pdf

#Squeeze example
import sys
import pycpdflib

#DLL loading depends on your own platform. These are the author's settings.
if sys.platform.startswith('darwin'):
    pycpdflib.loadDLL("/Users/john/repos/python-libcpdf/libpycpdf.so")
elif sys.platform.startswith('linux'):
    pycpdflib.loadDLL("../libpycpdf.so")
elif sys.platform.startswith('win32') or sys.platform.startswith('cygwin'):
    os.add_dll_directory("C:\\\\OCaml64/home/JohnWhitington/python-libcpdf/")
    pycpdflib.loadDLL("libpycpdf.dll")

#Load file
pdf = pycpdflib.fromFile('pycpdflibmanual.pdf', '')

#Squeeze it
pycpdflib.squeezeInMemory(pdf)

#Write output. We make sure to use toFileExt, and make object streams.
pycpdflib.toFileExt(pdf, 'squeezed.pdf', False, False, True, True, True)

Read the file pycpdflibmanual.pdf and squeeze it, writing to squeezed.pdf
