QgsClipToMinMaxEnhancement (QgsContrastEnhancement::QgsRasterDataType, double, double) | |
int | enhance (double) |
A customizable method that takes in a double and returns a int between 0 and 255. | |
bool | isValueInDisplayableRange (double) |
A customicable method to indicate if the pixels is displayable. |
For example if a min max range of [10,240] is specified in the constructor, and a value of 250 is called using enhance(), the value will be truncated ('clipped') to 240.
