Member Enumeration Documentation

enum Celartem::DjVu::JPXEncoder::CodingMode

The coding mode.
If lossless coding is desired, the integer mode must be used. By default, the integer mode is employed. The choice of mode also determines which multicomponent and wavelet transforms (if any) are employed.

Enumerator:

cm_Int	Integral mode.
cm_Real	Real mode.

enum Celartem::DjVu::JPXEncoder::Progression

The progression order.
By default, LRCP progressive ordering is employed. Note that the RPCL and PCRL progressions are not valid for all possible image geometries. (See ISO/IEC 15444-1 for more details.)

Enumerator:

prg_LRCP	layer-resolution-component-position (LRCP) progressive (i.e., rate scalable).
prg_RLCP	resolution-layer-component-position (RLCP) progressive (i.e., resolution scalable).
prg_RPCL	resolution-position-component-layer (RPCL) progressive.
prg_PCRL	position-component-resolution-layer (PCRL) progressive.
prg_CPRL	component-position-resolution-layer (CPRL) progressive.

Encode JPX image.

Parameters:

	inImage	The pointer to the first line in the RAW data.
