wx.Palette¶A palette is a table that maps pixel values to RGB colours.
It allows the colours of a low-depth bitmap, for example, to be mapped to the available colours in a display. The notion of palettes is becoming more and more obsolete nowadays and only the MSW port is still using a native palette. All other ports use generic code which is basically just an array of colours.
It is likely that in the future the only use for palettes within wxWidgets will be for representing colour indices from images (such as GIF or PNG). The image handlers for these formats have been modified to create a palette if there is such information in the original image file (usually 256 or less colour images). See wx.Image for more information.

Class API¶wx.Palette(GDIObject)¶Possible constructors:
Palette()
Palette(palette)
Palette(red, green, blue)
A palette is a table that maps pixel values to RGB colours.
__init__(self, *args, **kw)¶__init__ (self)
Default constructor.
__init__ (self, palette)
Copy constructor, uses Reference Counting.
palette (wx.Palette) – A reference to the palette to copy.
__init__ (self, red, green, blue)
Creates a palette from a set of sequences of integers, one for each red, green and blue color components.
red – A sequence of integer values in the range 0..255 inclusive.
green – A sequence of integer values in the range 0..255 inclusive.
blue – A sequence of integer values in the range 0..255 inclusive.
Note
All sequences must be the same length.
Create(self, red, green, blue)¶Creates a palette from 3 sequences of integers, one for each red, blue or green component.
red – A sequence of integer values in the range 0..255 inclusive.
green – A sequence of integer values in the range 0..255 inclusive.
blue – A sequence of integer values in the range 0..255 inclusive.
Note
All sequences must be the same length.
bool
GetColoursCount(self)¶Returns number of entries in palette.
int
GetPixel(self, red, green, blue)¶Returns a pixel value (index into the palette) for the given RGB values.
red (int) – Red value.
green (int) – Green value.
blue (int) – Blue value.
int
The nearest palette index or NOT_FOUND for unexpected errors.
