# README
Overview
Parse raw JPEG data into individual segments of data. You can print or export this data, including hash digests for each. You can also parse/modify the EXIF data and write an updated image.
EXIF, XMP, and IPTC data can also be extracted. The provided CLI tool can print this data as well.

# Structs
JpegMediaParser is a `riimage.MediaParser` that knows how to parse JPEG images.
JpegSplitter uses the Go stream splitter to divide the JPEG stream into segments.
Segment describes a single segment.
SegmentList contains a slice of segments.
SofSegment has info read from a SOF segment.
# Interfaces
SegmentVisitor describes a segment-visitor struct.
SofSegmentVisitor describes a visitor that is only called for each SOF segment.
