Remarks

Metadata such as EXIF, IPTC, and COM Markers are stored in as Jpeg Markers in JPEG files. This class allows Jpeg markers to be accessed and resaved in a new image (both lossy or lossless).

The marker data returned does not contain the first four bytes of actual marker data. These four bytes contain the length of the data and the marker type.
