# Documentation

type MutableMacroBlock s a = STVector s a #

Macroblock that can be transformed.

createEmptyMutableMacroBlock :: (Storable a, Num a) => ST s (MutableMacroBlock s a) #

Create a new macroblock with the good array size

printMacroBlock :: (Storable a, PrintfArg a) => MutableMacroBlock s a -> ST s String #

printPureMacroBlock :: (Storable a, PrintfArg a) => MacroBlock a -> String #

type DcCoefficient = Int16 #

Type only used to make clear what kind of integer we are carrying Might be transformed into newtype in the future

Instances details

Binary RestartInterval # |
Instance details Defined in Codec.Picture.Jpg.Internal.Types Methods put :: RestartInterval -> Put # get :: Get RestartInterval # putList :: [RestartInterval] -> Put #

getJpgImage :: Get JpgImage #

Like `get` from `instance Binary JpgImage`, but without the legacy semi-lazy implementation.

calculateSize :: SizeCalculable a => a -> Int #

dctBlockSize :: Num a => a #

parseECS :: Get ByteString #

Parses a Scan's ECS (Entropy-Coded Segment, the largest part of compressed image data) from the `Get` stream.

When this function is called, the parser's offset should be immediately behind the SOS tag.

As described on e.g. https://www.ccoderun.ca/programming/2017-01-31_jpeg/,

    To find the next segment after the SOS, you must keep reading until you
    find a 0xFF bytes which is not immediately followed by 0x00 (see "byte stuffing")
    [or a reset marker's byte: 0xD0 through 0xD7].
    Normally, this will be the EOI segment that comes at the end of the file.

where the 0xFF is the next segment's marker. See https://github.com/corkami/formats/blob/master/image/jpeg.md#entropy-coded-segment for more details.

This function returns the ECS, not including the next segment's marker on its trailing end.

parseECS_simple :: Get ByteString #

Simpler implementation of `parseECS` to allow an easier understanding of the logic, and to provide a comparison for correctness.

skipUntilFrames :: Get () #

skipFrameMarker :: Get () #

parseFrameOfKind :: JpgFrameKind -> Get (Maybe JpgFrame) #

Parses a single frame.

Returns `Nothing` when we encounter a frame we want to skip.

parseFrames :: Get [JpgFrame] #

Parse a list of `JpgFrame`s.

parseFrameKinds :: Get [(JpgFrameKind, Int64, Int64)] #

Parse a list of `JpgFrameKind`s with their corresponding offsets and lengths (not counting the segment and frame markers into the lengths).

Useful for debugging.

parseToFirstFrameHeader :: Get (Maybe JpgFrameHeader) #

Parses forward, returning the first scan header encountered.

Should be used after `skipUntilFrames`.

Fails parsing when an SOS segment marker (`JpgStartOfScan`, resulting in `JpgScanBlob`) is encountered before an SOF segment marker (that results in `JpgScans` carrying the `JpgFrameHeader`).
