Function
Displays an image in an X window.
Syntax
#include <dx/dx.h>
Object DXDisplayX(Object i, char *xdisplay, char *title)
Object DXDisplayX8(Object i, char *xdisplay, char *title)
Object DXDisplayX12(Object i, char *xdisplay, char *title)
Object DXDisplayX24(Object i, char *xdisplay, char *title)
Functional Details
Displays image i in an X window on the display specified by xdisplay, with the title specified by title. xdisplay is used as the X display string when opening the window. The window associated with xdisplay is maintained for subsequent calls to DXDisplayX until the user closes it, after which a new window is created.
These routines can utilize 8-bit pseudo color X visuals, 12-bit Direct Color and True Color visuals, and 24-bit Direct Color or True Color visuals.
DXDisplayX tries to create a window with the default visual, and if it is not of an appropriate type, tries to create an 8-bit, then 12-bit, then 24-bit visual. The other routines try to create the appropriate depth window first (for example, DXDisplayX8 tries to create an 8-bit window, then tries the default window depth.
| Note: | title cannot begin with a number or with two # characters. |
Return Value
Returns i or returns NULL and sets an error code.
