如何将Word文档/ pdf /图像的部分（每页多个部分，多页）提取为单独的图像/ Word文档/ pdfs？

Question

Here's the basic problem: I have about 10,000 word documents that contain blocks of data. Each block is numbered and also has an accompanying image. I need to somehow store these individual blocks to a db as images (text would be great, but read note below), without the numbering.

I can go through and have typists mark the beginning and ends of the blocks using a ###QUESTIONSTART###, ###QUESTIONEND### or whatever. I am trying to take that document, convert it to a big image, look for those tags, extract the part in between the tags as an image and then move on to the next block.

I've been looking at some APIs and I think I can definitely crop the images once I figure out how to get the coordinates of each start/end marker. Any suggestions? I'd hate to write a pixel by pixel matcher that has to go O(no of blocks * n^2)

NOTE: These blocks contain complex equations/math type stuff hence the images. I don't have the $$ to get 1000 typists trained in TeX and retype the whole deal. OCR doesn't cut it yet.

我无法理解您的所有问题，但在我看来， Tika可以为您提供帮助。

Answer 2

If you can have typists add block marks to 10,000 documents, why can't the typists

• Open the Word document
• Copy the image from the Word document
• Paste the image into Paint
• Save the image to their disk?

You can come up with a image naming scheme that makes sense to you and your typists.

Then you can collect the images from the disk drives with a program and load them into your database.
