Image File Helper

Helper functions/type for easily loading/managing image files, including animated gif files.

.. code:: cpp

#include <graphics/image-file.h>

.. struct:: gs_image_file

Image file structure

.. type:: gs_texture_t *gs_image_file.texture

Texture

.. type:: 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
