Using Substitution Filters with the "Image" Comparison Method

[Yanwa]

Hello,

So I'm trying to compare two PDFs to each other. Some of the things that I'm checking for are like font and verbiage so I was thinking that with the Image comparison method, I was able to get a diff report on showing these differences. However, I wasn't able to get the filters to work. Is there a way to get this to work or is there a better suited comparison method that I should be using? I was using the below regexs for working with the date and timestamp which I manage to get to work with the text comparison method but I couldn't get it to work with the image comparison method.

\d*/\d*/\d* and \d*:\d*

Unfortunately Substitution filters don't work for images.
To use Substitution filters, you need to extract and compare PDF text parts with Apache Tika plugin or xdocdiff WinMerge Plugin.

Thank you for the reply. I'll take a look at Apache Tika and xdocdiff.
