Image File Helper
|
|
=================
|
|
|
|
Helper functions/type for easily loading/managing image files, including
|
|
animated gif files.
|
|
|
|
.. code:: cpp
|
|
|
|
#include <graphics/image-file.h>
|
|
|
|
.. type:: struct gs_image_file
|
|
|
|
Image file structure
|
|
|
|
.. type:: gs_texture_t *gs_image_file.texture
|
|
|
|
Texture
|
|
|
|
.. type:: typedef struct gs_image_file gs_image_file_t
|
|
|
|
Image file type
|
|
|
|
---------------------
|
|
|
|
.. function:: void gs_image_file_init(gs_image_file_t *image, const char *file)
|
|
|
|
Loads an initializes an image file helper. Does not initialize the
|
|
texture; call :c:func:`gs_image_file_init_texture()` to initialize
|
|
the texture.
|
|
|
|
:param image: Image file helper to initialize
|
|
:param file: Path to the image file to load
|
|
|
|
---------------------
|
|
|
|
.. function:: void gs_image_file_free(gs_image_file_t *image)
|
|
|
|
Frees an image file helper
|
|
|
|
:param image: Image file helper
|
|
|
|
---------------------
|
|
|
|
.. function:: void gs_image_file_init_texture(gs_image_file_t *image)
|
|
|
|
Initializes the texture of an image file helper. This is separate
|
|
from :c:func:`gs_image_file_init()` because it allows deferring the
|
|
graphics initialization if needed.
|
|
|
|
:param image: Image file helper
|
|
|
|
---------------------
|
|
|
|
.. function:: bool gs_image_file_tick(gs_image_file_t *image, uint64_t elapsed_time_ns)
|
|
|
|
Performs a tick operation on the image file helper (used primarily
|
|
for animated file). Does not update the texture until
|
|
:c:func:`gs_image_file_update_texture()` is called.
|
|
|
|
:param image: Image file helper
|
|
:param elapsed_time_ns: Elapsed time in nanoseconds
|
|
|
|
---------------------
|
|
|
|
.. function:: void gs_image_file_update_texture(gs_image_file_t *image)
|
|
|
|
Updates the texture (used primarily for animated files)
|
|
|
|
:param image: Image file helper
