I have implemented basic colormap support for the X11 versions of
-wxWindows, notably wxPalette::Create(). The way I did it is to
+wxWidgets, notably wxPalette::Create(). The way I did it is to
allocate additional read-only color cells in the default colormap. In
general you will get arbitrary pixel values assigned to these new
-cells and therefore I added a method wxColourMap::TransferBitmap()
+cells and therefore I added a method wxPalette::TransferBitmap()
which maps the pixel values 0..n to the real ones obtained with
Create(). This is only implemented for the popular case of 8-bit
depth.
not the functionality that wxPalette::Create() aims to provide.
