Detailed Description
Filter to quantize samples in image.
Resulting samples will be unsigned with type and precision determined by the number of sample table entries.

| SPATMOD::IMAGE::FILTER_QUANTIZE::FILTER_QUANTIZE | ( | STAGE * | pPreviousStage, | |
| bool | TakeOwnership | |||
| ) |
Constructor.
- Parameters:
-
pPreviousStage Pointer to previous stage TakeOwnership Filter takes ownership of previous stage and will delete when needed
| virtual SPATMOD::IMAGE::FILTER_QUANTIZE::~FILTER_QUANTIZE | ( | ) | [virtual] |
Destructor.
Member Function Documentation
| const SAMPLETABLE& SPATMOD::IMAGE::FILTER_QUANTIZE::GetSampleTable | ( | UINT16 | SampleNum | ) | const |
Get sample table.
- Parameters:
-
SampleNum Sample index
| ERRVALUE SPATMOD::IMAGE::FILTER_QUANTIZE::SetSampleTable | ( | UINT16 | SampleNum, | |
| const SAMPLETABLE & | SampleTable | |||
| ) |
Set sample table.
Any component sample for which a table is not provided will be passed through filter unchanged. Sample values in table must be in numerically ascending sequence. Sample datatype must match corresponding sample of previous stage. Table values are considered to be minimum for quantizing to next sample. For example, if a table contains a single sample with value of 100, source samples < 100 will have output value of 0 and values >= 100 will have output value of 1. Resulting sample data type will be UINT8 with precision of 1.
- Parameters:
-
SampleNum Sample index SampleTable Sample table
