             Summary: Read PNG metadata from iTXt chunk
                 Key: IMAGING-342
                 URL: https://issues.apache.org/jira/browse/IMAGING-342

          Issue Type: Improvement
          Components: Format: PNG
            Reporter: Glavo


In [PNG 
specification|http://www.libpng.org/pub/png/spec/1.2/PNG-Chunks.html#C.Anc-text],
 {{iTXt}} chunk is semantically equivalent to the {{tEXt}} and {{zTXt}} chunks, 
but {{PngImageParser::getMetadata}} does not recognize the {{iTXt}} chunk.
