Hi David.
I have watched a strange behaviour in the filter support implementation
while I was writing AESv2 filter. My _apply function is being called
several times with the input buffer at EOB. I don't how to manage this
in AESv2 filter, since an empty buffer is a valid input. May anyone
explain because I am getting this?
Your _apply function can be called with an eob input buffer in the
following situations:
- After returning PDF_ENOUTPUT. finish_p can be PDF_TRUE or
PDF_FALSE in this case.
- After returning PDF_ENINPUT. finish_p is PDF_TRUE in this case.
What is your specific situation?
