| caca_display_t * | caca_create_display (cucul_canvas_t *) |
| Attach a caca graphical context to a cucul canvas. | |
| void | caca_free_display (caca_display_t *) |
| Detach a caca graphical context from a cucul backend context. | |
| void | caca_set_delay (caca_display_t *, unsigned int) |
| Set the refresh delay. | |
| void | caca_refresh_display (caca_display_t *) |
| Flush pending changes and redraw the screen. | |
| unsigned int | caca_get_rendertime (caca_display_t *) |
| Get the average rendering time. | |
| unsigned int | caca_get_display_width (caca_display_t *) |
| Get the display width. | |
| unsigned int | caca_get_display_height (caca_display_t *) |
| Get the display height. | |
| int | caca_set_display_title (caca_display_t *, char const *) |
| Set the display title. | |
|
|
Create a graphical context using device-dependent features (ncurses for terminals, an X11 window, a DOS command window...) that attaches to a libcucul canvas. Everything that gets drawn in the libcucul canvas can then be displayed by the libcaca driver.
|
|
|
Detach a graphical context from its cucul backend and destroy it. The libcucul canvas continues to exist and other graphical contexts can be attached to it afterwards.

This function sets the refresh delay in microseconds. The refresh delay is used by caca_refresh_display() to achieve constant framerate. See the caca_refresh_display() documentation for more details. If the argument is zero, constant framerate is disabled. This is the default behaviour.

|
This function flushes all graphical operations and prints them to the screen. Nothing will show on the screen until caca_refresh_display() is called. If caca_set_delay() was called with a non-zero value, caca_refresh_display() will use that value to achieve constant framerate: if two consecutive calls to caca_refresh_display() are within a time range shorter than the value set with caca_set_delay(), the second call will be delayed before performing the screen refresh.

|
This function returns the average rendering time, which is the average measured time between two caca_refresh_display() calls, in microseconds. If constant framerate was activated by calling caca_set_delay(), the average rendering time will not be considerably shorter than the requested delay even if the real rendering time was shorter.

If libcaca runs in a window, get the usable window width. This value can be used for aspect ratio calculation. If libcaca does not run in a window or if there is no way to know the font size, most drivers will assume a 6x10 font is being used. Note that the units are not necessarily pixels.

If libcaca runs in a window, try to change its title. This works with the X11 and Win32 drivers.
