  • Status changed from new to open

I had old patches implementing that, I just updated them and submitted them to the mailing-list.

I do not have samples with iTXt chunks. Do you have any, or can you suggest a tool to produce some?

tEXt and zTXt decoding implemented and pushed. iTXt still waiting for a sample.

Is there anything else you want? The details on your ticket are rather sparse.
