Performs Inverse LMM DCT and dequantization
Return image height, width and number of components, plus the type of Adobe colorpsace transform
Loads huffman tables on specified destinations
Builds up decoder-specific tables
The DECODE procedure, as described in CCITT rec.
Decodes AC coefficients
Reads one 8x8 block. Doesn’t deals with predictors.
Reads and decodes either a whole scan (if no restarts) or restart interval
Decodes DC value
Return the height and width of the JPEG data read from STREAM. Does less work than DECODE-STREAM and also supports progressive DCT-based JPEGs.
Dequantizes a single sample
jpeg.

Reads tables etc., returns the first unrecognized marker it met
Performs inverse zigzag block arrangement
Performs inverse zigzag block arrangement
Returns the closure which reads specified numbers of bits from the stream
APPn marker reading: just skipping the whole marker
APPn marker reading: just skipping the whole marker
Recieves ssss bits from the stream
Places decoded block into the image buffer, with necessary upsampling
