pdf - 如何使用 Acrobat SDK 将 PDF 转换为 Word？

Question

我的 .Net 应用程序需要以编程方式将 PDF 文档转换为 Word 格式。

我评估了几种产品并找到了Acrobat X Pro，它提供了另存为选项，我们可以将文档保存为 Word/Excel 格式。我尝试使用 Acrobat SDK，但找不到合适的文档从哪里开始。

我查看了他们的 IAC 示例，但不明白如何调用菜单项并使其执行另存为选项。

Answer 1

您可以使用 Acrobat X Pro 执行此操作，但您需要使用 c# 中的 javascript API。

 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);

希望有帮助。

我使用 WinPython x64 2.7.6.3 和 Acrobat X Pro 做了一些非常相似的事情，并使用 JSObject 接口将 PDF 转换为 DOCX。与jle 的解决方案基本相同。

下面应该是一段完整的将一组 PDF 转换为 DOCX 的代码：

# 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)

Adobe 不支持 PDF 到 Word 的转换，除非您使用他们的 Acrobat PDF 客户端。Maeaning 你不能用他们的 SDK 或调用命令行来做到这一点。您只能手动进行。
