- a connection "host:server.screen" <br>
- a colormap mapping of type Xw_TOM_xxxxx <br>
- a "UseDefault" flag which permits the use of the <br>
DefaultColormap if possible. <br>
The connection can be specified directly
or extracted from an existing Window.
All Xw_Windows may share the same Graphic Device if
you don't want to have any side effects on the stations
which have only one hardware pseudo-colormap .
Four kind of mapping are possible :
1) Xw_TOM_SIMPLERAMP
Allocates the number of required colors in the
colormap.
The number of user colors depends directly on
the hardware colormap size if UseDefault is False,
or on the remainding free colors in the hardware colormap
if UseDefault is True.
2) Xw_TOM_BESTRAMP
Allocates the number of required colors in the
colormap but leaves the Odd color indexes free
if possible for highlight color management.
(plane 0 is reserved for this usage)
The number of user colors depends directly on
the hardware colormap size if UseDefault is False,
or on the remainding free colors in the hardware colormap
if UseDefault is True.
3) Xw_TOM_COLORCUBE (the default)
Allocates the maximum available colors in the colormap
and builds a colorcube at this place.
Any user color will be approximate and will be chosen as
the nearest of the set of available colorcube colors.
In this case the number of user colors can be unlimited.
4) Xw_TOM_HARDWARE
May do serious damage to the color system.
Must be used for maintenance only.
5) Xw_TOM_READONLY
Allocates the number of required read only colors in the
default colormap.
The number of user colors depends directly on
the hardware colormap size.
