检查Word文档中是否存在特定图像 [英] Check whether a particular image is present in a Word document

问题描述

大家好，

我们有一个项目要求，我们需要检查Word/Excel文档中是否存在特定图像.

注意:如果完全有图像存在，它将出现在文档末尾.

例如，我们有一个Word文档(Word.docx)和一个图像(Image1.jpg).我需要检查Word文档"Word.docx"是否最后包含图像"Image1.jpg".

请注意，我正在使用编程语言C#

我在相当长的一段时间内都在为这个问题而苦苦挣扎.我找不到来自互联网的适当帮助.
任何人都可以帮助我实现这一目标吗?

在此先感谢，
Kishor Reddy

Can anyone help me acheiving this ?

解决方案

Using Interop, the InlineShapes[^] of the document should contain the pictures so if you loop through that, you should find the pictures.

using InlineShapes, i got the last image of the word document. and compared the pixels of both the images (the last image of the word document and the other image).

Steps:
1. Get the last image of the document using InlineShapes
2. Convert to bitmap.
3. Convert each pixel of the custom image.
4. If all the pixels are equal, then both the images are same.

Sometimes, based on the Word properties, borders are added to the embedded image. While comparing the pixels, we need to ignore the pixels related to the borders.

thanks....
