Cómo convertir PDF a Word usando Acrobat SDK?

Question

Mi aplicación .Net necesita convertir un documento PDF a formato de Word mediante programación.

Evalué varios productos y encontré Acrobat X Pro, que proporciona una opción para guardar como guardar el documento en formato Word/Excel. Traté de usar Acrobat SDK pero no pude encontrar la documentación adecuada desde donde comenzar.

Miré su muestra de IAC pero no pude entender cómo llamar al elemento del menú y hacer que ejecute la opción de guardar como.

Answer 1

Adobe no es compatible con las conversiones de PDF a Word, a menos que esté utilizando su cliente de Acrobat PDF. Maeaning no puede hacerlo con su SDK ni llamando a una línea de comandos. Solo puedes hacerlo manualmente.

Answer 2

Puede hacer esto con Acrobat X Pro, pero necesita usar la API de JavaScript en C#.

AcroPDDoc pdfd = new AcroPDDoc(); 
pdfd.Open(sourceDoc.FileFullPath); 
Object jsObj = pdfd.GetJSObject(); 
Type jsType = pdfd.GetType(); 
//have to use acrobat javascript api because, acrobat 
object[] saveAsParam = { "newFile.doc", "com.adobe.acrobat.doc", "", false, false }; 
jsType.InvokeMember("saveAs",BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Instance,null, jsObj, saveAsParam, CultureInfo.InvariantCulture); 

Espero que ayude.

Hice algo muy similar usando WinPython x64 2.7.6.3 y Acrobat X Pro y utilicé la interfaz JSObject para convertir archivos PDF a DOCX. Esencialmente la misma solución que jle's.

Lo siguiente debe ser una pieza completa de código que convierte un conjunto de archivos PDF a DOCX:

# gets all files under ROOT_INPUT_PATH with FILE_EXTENSION and tries to extract text from them into ROOT_OUTPUT_PATH with same filename as the input file but with INPUT_FILE_EXTENSION replaced by OUTPUT_FILE_EXTENSION 
from win32com.client import Dispatch 
from win32com.client.dynamic import ERRORS_BAD_CONTEXT 

import winerror 

# try importing scandir and if found, use it as it's a few magnitudes of an order faster than stock os.walk 
try: 
    from scandir import walk 
except ImportError: 
    from os import walk 

import fnmatch 

import sys 
import os 

ROOT_INPUT_PATH = None 
ROOT_OUTPUT_PATH = None 
INPUT_FILE_EXTENSION = "*.pdf" 
OUTPUT_FILE_EXTENSION = ".docx" 

def acrobat_extract_text(f_path, f_path_out, f_basename, f_ext): 
    avDoc = Dispatch("AcroExch.AVDoc") # Connect to Adobe Acrobat 

    # Open the input file (as a pdf) 
    ret = avDoc.Open(f_path, f_path) 
    assert(ret) # FIXME: Documentation says "-1 if the file was opened successfully, 0 otherwise", but this is a bool in practise? 

    pdDoc = avDoc.GetPDDoc() 

    dst = os.path.join(f_path_out, ''.join((f_basename, f_ext))) 

    # Adobe documentation says "For that reason, you must rely on the documentation to know what functionality is available through the JSObject interface. For details, see the JavaScript for Acrobat API Reference" 
    jsObject = pdDoc.GetJSObject() 

    # Here you can save as many other types by using, for instance: "com.adobe.acrobat.xml" 
    jsObject.SaveAs(dst, "com.adobe.acrobat.docx") # NOTE: If you want to save the file as a .doc, use "com.adobe.acrobat.doc" 

    pdDoc.Close() 
    avDoc.Close(True) # We want this to close Acrobat, as otherwise Acrobat is going to refuse processing any further files after a certain threshold of open files are reached (for example 50 PDFs) 
    del pdDoc 

if __name__ == "__main__": 
    assert(5 == len(sys.argv)), sys.argv # <script name>, <script_file_input_path>, <script_file_input_extension>, <script_file_output_path>, <script_file_output_extension> 

    #$ python get.docx.from.multiple.pdf.py 'C:\input' '*.pdf' 'C:\output' '.docx' # NOTE: If you want to save the file as a .doc, use '.doc' instead of '.docx' here and ensure you use "com.adobe.acrobat.doc" in the jsObject.SaveAs call 

    ROOT_INPUT_PATH = sys.argv[1] 
    INPUT_FILE_EXTENSION = sys.argv[2] 
    ROOT_OUTPUT_PATH = sys.argv[3] 
    OUTPUT_FILE_EXTENSION = sys.argv[4] 

    # tuples are of schema (path_to_file, filename) 
    matching_files = ((os.path.join(_root, filename), os.path.splitext(filename)[0]) for _root, _dirs, _files in walk(ROOT_INPUT_PATH) for filename in fnmatch.filter(_files, INPUT_FILE_EXTENSION)) 

    # patch ERRORS_BAD_CONTEXT as per https://mail.python.org/pipermail/python-win32/2002-March/000265.html 
    global ERRORS_BAD_CONTEXT 
    ERRORS_BAD_CONTEXT.append(winerror.E_NOTIMPL) 

    for filename_with_path, filename_without_extension in matching_files: 
     print "Processing '{}'".format(filename_without_extension) 
     acrobat_extract_text(filename_with_path, ROOT_OUTPUT_PATH, filename_without_extension, OUTPUT_FILE_EXTENSION)
