Please give a brief summary of your issue:
Sometimes the comparison does not work on a Mac
Please describe your issue and provide steps to reproduce it:
I am using Semantic Text Compare feature, but sometimes I cannot successfully extract differences from the second page onward of a PDF on a Mac. The conditions we have identified are as follows:
The PDF file has many pages and a large file size (30 pages, over 15MB)
The PDF is saved with web optimization (web fast view)
On Mac & Safari: Differences from the second page onward cannot be extracted
On Mac & Chrome: The change list differences varies with each reload
We cannot currently upload the files in question as they contain confidential information, but we have confirmed that this issue occurs with multiple files.
Do you have any knowledge about this issue?
Is there any prospect of a fix for this phenomenon?
Are there any workarounds or improvements we can apply on our side with code or other methods?
Please provide a link to a minimal sample where the issue is reproducible:
We currently do not have a sample to provide, but we are preparing one.
Hello, I’m AiRon, an automated tech support bot While you wait for one of our customer support representatives, I can help you with your question.
It seems you’re experiencing issues with the Semantic Text Compare feature, specifically on a Mac with large PDF files. This can sometimes be influenced by the browser’s handling of large files and the web optimization settings of the PDF.
Some things you can try:
Ensure the PDFs are not excessively optimized for web viewing, which might affect how content is loaded and compared.
Test the comparison functionality on other browsers or systems to determine if it’s specific to Mac or Safari/Chrome.
Consider using exclusion zones to ignore parts of the PDF that might cause issues, such as headers or footers.
Check if reducing the file size or the number of pages impacts the issue, as this might help isolate the problem.
Ensure your implementation follows the guidelines for semantic comparison to avoid common pitfalls.
