---------------------------------

             Summary: All tEXt chunks are not returned from PngImageParser.getMetadata
                 Key: IMAGING-199
                 URL: https://issues.apache.org/jira/browse/IMAGING-199
             Project: Commons Imaging
          Issue Type: Bug
          Components: Format: PNG
            Reporter: Ric Emery
            Priority: Minor


According to the PNG spec - Section 4.2.3 - Textual Information -

"Any number of text chunks can appear, and more than one with the same keyword is permissible. "

Unfortunately the PngImageParser.getMetadata method only supports a single tEXt chunk.  The problem is in the following line:

        final List<PngChunk> chunks = readChunks(byteSource, new ChunkType[] { ChunkType.tEXt, ChunkType.zTXt, }, true);

True is being passed for returnAfterFirst. I believe that false should be passed instead.

I can submit a pull request if you agree.
