Functions
static void	encodeNextChunkAscii (DmtxEncodeStream *stream, int option)
	Simple single scheme encoding uses "Normal" The optimizer needs to track "Expanded" and "Compact" streams separately, so they are called explicitly.
static void	appendValueAscii (DmtxEncodeStream *stream, DmtxByte value)
	this code is separated from encodeNextChunkAscii() because it needs to be called directly elsewhere
static void	completeIfDoneAscii (DmtxEncodeStream *stream, int sizeIdxRequest)
static void	padRemainingInAscii (DmtxEncodeStream *stream, int sizeIdx)
	Can we just receive a length to pad here? I don't like receiving sizeIdxRequest (or sizeIdx) this late in the game.
static DmtxByteList	encodeTmpRemainingInAscii (DmtxEncodeStream *stream, DmtxByte *storage, int capacity, DmtxPassFail *passFail)
	consider receiving instantiated DmtxByteList instead of the output components
static DmtxByte	randomize253State (DmtxByte cwValue, int cwPosition)
	Randomize 253 state.

appendValueAscii()

static void appendValueAscii ( DmtxEncodeStream * stream, DmtxByte value )

static

this code is separated from encodeNextChunkAscii() because it needs to be called directly elsewhere

Definition at line 95 of file dmtxencodeascii.c.

completeIfDoneAscii()

static void completeIfDoneAscii ( DmtxEncodeStream * stream, int sizeIdxRequest )

static

Definition at line 108 of file dmtxencodeascii.c.

encodeNextChunkAscii()

static void encodeNextChunkAscii ( DmtxEncodeStream * stream, int option )

static

Simple single scheme encoding uses "Normal" The optimizer needs to track "Expanded" and "Compact" streams separately, so they are called explicitly.

Normal: Automatically collapses 2 consecutive digits into one codeword Expanded: Uses a whole codeword to represent a digit (never collapses) Compact: Collapses 2 digits into a single codeword or marks the stream invalid if either values are not digits

Parameters

stream
option	[Expanded|Compact|Normal]

Definition at line 35 of file dmtxencodeascii.c.

encodeTmpRemainingInAscii()

static DmtxByteList encodeTmpRemainingInAscii ( DmtxEncodeStream * stream, DmtxByte * storage, int capacity, DmtxPassFail * passFail )

static

consider receiving instantiated DmtxByteList instead of the output components

Definition at line 159 of file dmtxencodeascii.c.

padRemainingInAscii()

static void padRemainingInAscii ( DmtxEncodeStream * stream, int sizeIdx )

static

Can we just receive a length to pad here? I don't like receiving sizeIdxRequest (or sizeIdx) this late in the game.

Definition at line 129 of file dmtxencodeascii.c.

randomize253State()

static DmtxByte randomize253State ( DmtxByte cwValue, int cwPosition )

static

Randomize 253 state.

Parameters

cwValue	codewordValue
cwPosition	codewordPosition

Returns

Randomized value
