Member Type Documentation
enum QColormap::Mode
This enum describes how QColormap maps device independent RGB values to device dependent pixel values.
Constant | Value | Description |
---|---|---|
QColormap::Direct | 0 | Pixel values are derived directly from the RGB values, also known as "True Color." |
QColormap::Indexed | 1 | Pixel values represent indexes into a vector of available colors, i.e. QColormap uses the index of the color that most closely matches an RGB value. |
QColormap::Gray | 2 | Similar to Indexed , pixel values represent a vector of available gray tones. QColormap uses the index of the gray tone that most closely matches the computed gray tone of an RGB value. |
