I am doing something like extracting the pdf text in a string format so as to annotate the text and in the same process i need to find the image positions covered in the same pdf file so as to maintain its position. Now the problem is that i am not getting the exact positions of the images in the same pdf file. Is it possible to use some thing like OCR,if yes,how to use that?
我正在做一些事情，比如以字符串格式提取pdf文本以便注释文本，并且在同一过程中我需要找到同一pdf文件中所覆盖的图像位置，以便保持其位置。现在的问题是我没有在同一个pdf文件中获得图像的确切位置。是否可以使用像OCR这样的东西，如果是的话，如何使用它？
Can anybody help me in finding the exact position of the image in the pdf file? I need to implement some pdf reader kind of application for ipad,that's just for the knowledge.
任何人都可以帮我找到pdf文件中图像的确切位置吗？我需要为ipad实现一些pdf阅读器类应用程序，这只是为了知识。
Thank you.
谢谢。

Isn't OCR a little bit heavy weight for iphone? Take look on tools like pdftotext from Xpdf. It is much simpler to read data, as to render and recognize it back again.
对于iPhone，OCR不是有点重吗？查看来自Xpdf的pdftotext等工具。读取数据要简单得多，以便再次渲染和识别它。
