Detailed Description

class PySide2.QtWidgets.QColormap(colormap)

param colormap:

PySide2.QtWidgets.QColormap

Constructs a copy of another colormap .

PySide2.QtWidgets.QColormap.Mode

This enum describes how QColormap maps device independent RGB values to device dependent pixel values.

Constant	Description
QColormap.Direct	Pixel values are derived directly from the RGB values, also known as “True Color.”
QColormap.Indexed	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	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.
