Hi All - (First time on this mailing list)
In my log files I see a lot of errors similar to what is in the imaging-177 issue when trying to get image metadata from a jpeg. I took a sample image that had the error to investigate, and found that the image appears to have an embedded thumbnail (tags 0x201 and 0x202) where the start of the thumbnail is not contiguous with the rest of the IFD entries & data. The bytes returned by JpegImageParser.getExifRawData(...) do not include this data, which ultimately results this exception: java.lang.IllegalArgumentException: Couldn't read array (start: 1396, length: -280, data length: 1116). at org.apache.commons.io.build.AbstractOrigin.getByteArray(AbstractOrigin.java:521) at org.apache.commons.imaging.bytesource.ByteSource.getByteArray(ByteSource.java:63) at org.apache.commons.imaging.formats.tiff.TiffReader.getJpegRawImageData(TiffReader.java:147) at org.apache.commons.imaging.formats.tiff.TiffReader.readDirectory(TiffReader.java:373) at org.apache.commons.imaging.formats.tiff.TiffReader.readDirectory(TiffReader.java:423) at org.apache.commons.imaging.formats.tiff.TiffReader.readDirectories(TiffReader.java:271) at org.apache.commons.imaging.formats.tiff.TiffReader.read(TiffReader.java:216) at org.apache.commons.imaging.formats.tiff.TiffReader.readContents(TiffReader.java:223) at org.apache.commons.imaging.formats.tiff.TiffImageParser.getMetadata(TiffImageParser.java:614) at org.apache.commons.imaging.formats.tiff.TiffImageParser.getMetadata(TiffImageParser.java:73) at org.apache.commons.imaging.AbstractImageParser.getMetadata(AbstractImageParser.java:652) at org.apache.commons.imaging.formats.jpeg.JpegImageParser.getExifMetadata(JpegImageParser.java:232) at org.apache.commons.imaging.formats.jpeg.JpegImageParser.getMetadata(JpegImageParser.java:642) at org.apache.commons.imaging.formats.jpeg.JpegImageParser.getMetadata(JpegImageParser.java:65) at org.apache.commons.imaging.Imaging.getMetadata(Imaging.java:565) at org.apache.commons.imaging.Imaging.getMetadata(Imaging.java:560) The image I used for this deep-dive appears to have been created by a Samsung A32 phone. That model was released in 2021. Is this something that can be addressed? I don't have an account on your Jira, but I can create one if desired so I can add the sample image. Thanks, Chad
