DTK_DESTROY_TEXTURE(3)						Draw Toolkit manual					    DTK_DESTROY_TEXTURE(3)

NAME
dtk_destroy_texture - Free a texture SYNOPSIS
#include <drawtk.h> void dtk_destroy_texture(dtk_htex tex); DESCRIPTION
This function frees the ressource associated with a texture tex. If the texture is used several times, i.e. several call to dtk_load_image() with the same image path, it decreases the number of uses by one. Calling dtk_destroy_texture() on each created texture is currently not mandatory since all texture remaining textures are destroyed when the last window is closed. However, if no window can be closed (for example, no window has been created), dtk_destroy_texture() should be called on each created texture to avoid any memory leak. dtk_destroy_texture() is thread-safe. RETURN VALUE
None SEE ALSO

DTK_LOAD_VIDEO_TEST(3)						Draw Toolkit manual					    DTK_LOAD_VIDEO_TEST(3)

NAME
dtk_load_video_test - Load an test video as a texture SYNOPSIS
#include <dtk_video.h> dtk_htex dtk_load_video_test(int flags); DESCRIPTION
This function loads a test video file as a dynamic texture. The texture will then been tracked by an internal texture manager so that the next call will return the same texture handle, thus sparing the resources of the system. If not specified by flags the video will not be played immediately and dtk_video_exec(3) should be called to do start playing. The argument flags is used to modify the creation. It should contains a bitwise OR combination of the following flags: DTK_AUTOSTART : Indicates that the video should start immediately after creation. DTK_NOBLOCKING : Indicates that the creation function should not block waiting that the video pipeline is fully running. A dynamic texture can be used the same way as a static texture (for example image file). The only difference is that the content of the texture changes automatically with the stream of video. This means that every time a shape using this texture is drawn, the latest frame available from the video stream will be mapped on the shape. There is no need for a valid window to create successfully a texture, i.e. creation of textures are completely decoupled from the creation of others resources and can even be created in one thread to be used in another one. Once a the texture is stopped being used, it should be destroyed by dtk_destroy_texture(3). RETURN VALUE
In case of success, the function returns the handle to the created texture. In case of failure, NULL is returned. THREAD SAFETY
dtk_load_video_test() is thread-safe. SEE ALSO
