Ric Emery created IMAGING-199:
---------------------------------
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.
