These functions are declared in the following header file:

 #include <allegro5/allegro_direct3d.h>

al_get_d3d_device

LPDIRECT3DDEVICE9 al_get_d3d_device(ALLEGRO_DISPLAY *display)

Returns the Direct3D device of the display. The return value is undefined if the display was not created with the Direct3D flag.

Returns: A pointer to the Direct3D device.

al_get_d3d_system_texture

LPDIRECT3DTEXTURE9 al_get_d3d_system_texture(ALLEGRO_BITMAP *bitmap)

Returns the system texture (stored with the D3DPOOL_SYSTEMMEM flags). This texture is used for the render-to-texture feature set.

Returns: A pointer to the Direct3D system texture.

al_get_d3d_video_texture

LPDIRECT3DTEXTURE9 al_get_d3d_video_texture(ALLEGRO_BITMAP *bitmap)

Returns the video texture (stored with the D3DPOOL_DEFAULT or D3DPOOL_MANAGED flags depending on whether render-to-texture is enabled or disabled respectively).

Returns: A pointer to the Direct3D video texture.

al_have_d3d_non_pow2_texture_support

bool al_have_d3d_non_pow2_texture_support(void)

Returns whether the Direct3D device supports textures whose dimensions are not powers of two.

Returns: True if device suports NPOT textures, false otherwise.

al_have_d3d_non_square_texture_support

bool al_have_d3d_non_square_texture_support(void)

Returns whether the Direct3D device supports textures that are not square.

Returns: True if the Direct3D device suports non-square textures, false otherwise.

al_get_d3d_texture_size

bool al_get_d3d_texture_size(ALLEGRO_BITMAP *bitmap, int *width, int *height)

Retrieves the size of the Direct3D texture used for the bitmap.

Returns true on success, false on failure. Zero width and height are returned if the bitmap is not a Direct3D bitmap.

Since: 5.1.0

al_get_d3d_texture_position

void al_get_d3d_texture_position(ALLEGRO_BITMAP *bitmap, int *u, int *v)

Returns the u/v coordinates for the top/left corner of the bitmap within the used texture, in pixels.

Parameters:

See also: al_get_d3d_texture_size

al_is_d3d_device_lost

bool al_is_d3d_device_lost(ALLEGRO_DISPLAY *display)

Returns a boolean indicating whether or not the Direct3D device belonging to the given display is in a lost state.

Parameters:

al_set_d3d_device_release_callback

void al_set_d3d_device_release_callback(
   void (*callback)(ALLEGRO_DISPLAY *display))

The callback will be called whenever a D3D device is reset (minimize, toggle fullscreen window, etc). In the callback you should release any d3d resources you have created yourself. The callback receives the affected display as a parameter.

Pass NULL to disable the callback.

Since: 5.1.0

al_set_d3d_device_restore_callback

void al_set_d3d_device_restore_callback(
   void (*callback)(ALLEGRO_DISPLAY *display))

The callback will be called whenever a D3D device that has been reset is restored. In the callback you should restore any d3d resources you have created yourself. The callback receives the affected display as a parameter.

Pass NULL to disable the callback.

Since: 5.1.0
