This struct contains parameters to configure the IW44 encoder settings.
|
inline |
Initializes the structure by specifying quality value.
| inIntent | The intent of encoding. This is one of the Intent enumeration values. |
| inQuality | The encoding quality in 0-100. 100 for the highest quality but the largest size. 0 for the lowest quality and the smallest file size. The default is 75. |
| inCbcrMode | The CBCRMode. The default is cbcrNormal. If inIntent is BM44, CBCRMode is forced to change to cbcrNone ignoring this value. |
| inCbcrDelay | The chrominance delay counter in 0 - 127. In addition to these range of values, cbcrDelayAuto can be used to make encoder determine it from other parameters. This value is used to specify how many slices contains only luminance (Y) component. The default is cbcrDelayAuto. |
|
inline |
Initializes the structure by specifying chunk configurations.
| inIntent | The intent of encoding. This is one of the Intent enumeration values. |
| inChunkConfigs | The pointer to the ChunkConfig array. |
| inChunkConfigCount | The number of elements in the inChunkConfigs. |
| inCbcrMode | The CBCRMode. The default is cbcrNormal. If inIntent is BM44, CBCRMode is forced to change to cbcrNone ignoring this value. |
| inCbcrDelay | The chrominance delay counter in 0 - 127. In addition to these range of values, cbcrDelayAuto can be used to make encoder determine it from other parameters. This value is used to specify how many slices contains only luminance (Y) component. The default is cbcrDelayAuto. |
|
inline |
Initializes the structure by specifying slice callback function.
| inIntent | The intent of encoding. This is one of the Intent enumeration values. |
| inSliceCallback | The pointer to the callback function which is called right after each of slice encoding iteration. |
| inSliceCallbackContext | The pointer to user defined context data. It is given to the callback specified as inSliceCallback. |
| inCbcrMode | The CBCRMode. The default is cbcrNormal. If inIntent is BM44, CBCRMode is forced to change to cbcrNone ignoring this value. |
| inCbcrDelay | The chrominance delay counter in 0 - 127. In addition to these range of values, cbcrDelayAuto can be used to make encoder determine it from other parameters. This value is used to specify how many slices contains only luminance (Y) component. The default is cbcrDelayAuto. |
| void Celartem::DjVu::IW44Encoder::Params::configureChunks | ( | Intent | inIntent, |
| size_t | inQuality | ||
| ) |
This method is a helper method, which configures chunkConfigs from the specified intent and quality.
Note that this method never changes intent and quality variable of the instance but just modifies chunkConfig variable due to the specified parameter.
| inIntent | The intent of encoding. This is one of the Intent enumeration values. |
| inQuality | The encoding quality in 0-100. 100 for the highest quality but the largest size. 0 for the lowest quality and the smallest file size. The default is 75. |
| size_t Celartem::DjVu::IW44Encoder::Params::cbcrDelay |
The chrominance delay counter in 0 - 127.
The chrominance delay counter in 0 - 127. In addition to these range of values, cbcrDelayAuto can be used to make encoder determine it from other parameters. This value is used to specify how many slices contains only luminance (Y) component.
The default is cbcrDelayAuto.
| CBCRMode Celartem::DjVu::IW44Encoder::Params::cbcrMode |
Cb-Cr (chrominance) mode.
The default is cbcrNormal. If inIntent is BM44, CBCRMode is forced to change to cbcrNone ignoring this value.
| SimpleArray<ChunkConfig> Celartem::DjVu::IW44Encoder::Params::chunkConfigs |
Configurations for IW44 chunks.
This parameter is only used when the following conditions are met:
NULL NULL And then quality variable is simply ignored. Referenced by Params().
| Intent Celartem::DjVu::IW44Encoder::Params::intent |
Intent of the encoding.
The intent of the encoding. IW44Encoder configures the internal parameters according to the intent.
| size_t Celartem::DjVu::IW44Encoder::Params::quality |
Quality of the IW44 encoding.
100 for the highest quality but the largest size. 0 for the lowest quality and the smallest file size.
The default is 75.
This parameter is only used when the following conditions are met:
NULL NULL chunkConfigs will be configured when needed according to this parameter. To configure chunkConfigs before calling IW44Encoder::create, use configureChunks method.
| SliceCallback Celartem::DjVu::IW44Encoder::Params::sliceCallback |
Callback function called on each slice encoding iteration.
The pointer to the callback function which is called right after each of slice encoding iteration.
| void* Celartem::DjVu::IW44Encoder::Params::sliceCallbackContext |
User defined parameter for callback.
The pointer to user defined context data. It is given to the callback specified as sliceCallback.
