"Access Violation" exception while accessing PDEImage in outside of the class as a parameter

Question

Hi,
In our project, we are retrieving PDEImage content from PDF Page by using below line of code in our Plugin project:
But we are getting "Access Violation" exception while accessing retrieved PDEImage in outside of the class as a parameter.
This issue is happening only in Windows 8.1 and Acrobat 11 combination.
If we remove the above highlighted lines from the method then no exception and working fine.
But we don't know why these lines are added, because we are not updating any of the PDF content here.
We are planning to remove these highlighted lines from the method.
We want to know whether the removing of these lines will impact the application.
Kindly help us to resolve the issue.

Answer 1

And will removing the lines impact the application? Certainly. If you do not call PDPageReleasePDEContent you will have a memory leak at best, or may prevent other activity from completing (such as saving or closing the file). The first two lines, however, are redundant since you do not seem to be actually changing the page.
You must call PDPageReleasePDEContent  when you have finished with the content, in every case.
