[matplotlib-devel] GTK colors

[Steve C. <ste...@ya...>]

John,
I'm trying to understand the methods
backend_gtk.ColorManagerGTK.get_color()
backend_gtk.ColorManagerGTK.get_rgb()
They convert color representations from rgb (three floats in the range
0.0 - 1.0) to gdk.Color (three integers in the range 0 - 65535)

get_rgb() divides by 65535 but get_color() multiplies by 65025. So if
I run

>>> import gtk
>>> import backend_gtk
>>> cm=backend_gtk.ColorManagerGTK()
>>> cm.set_drawing_area(gtk.DrawingArea())
>>> gdk_color=gtk.gdk.Color(1000,1000,1000)
>>> rgb_color=cm.get_rgb(gdk_color)
>>> gdk_color=cm.get_color(rgb_color)
>>> print gdk_color.red, gdk_color.green, gdk_color.blue
992 992 992

The color (1000,1000,1000) has become (992,992,992).
It looks to me like get_color() should multiply by 65535, or is there 
a special reason for using 65025?

Regards,
Steve
