This is a command-line JPEG image viewer backed by a Java decoder. The user supplies a JPEG path; the viewer invokes decoding, which parses markers and scans, reconstructs coefficients, transforms blocks into samples, converts them into a BufferedImage, and schedules Swing display. The README documents baseline and progressive Huffman JPEG support, grayscale/RGB/YCbCr conversion, and restart intervals. The decoder excerpt and README establish the principal calls; decoder internals are grouped where the excerpt does not expose distinct calls.
