Function Documentation

EZ_create_image()

EZ_image * EZ_create_image	(	SDL_Surface *	surface,
		SDL_Renderer *	renderer,
		anchore_point	dst_anchore,
		int	auto_aspect )

Creates an EZ_image from an SDL_Surface.

This function creates an EZ_image structure from the given SDL_Surface and renderer. The created EZ_image can be used for rendering with SDL.

Parameters

surface	The SDL_Surface to create the image from.
renderer	The SDL_Renderer to use for creating the texture.
dst_anchore	The anchore point for the destination.
auto_aspect	If non-zero, the aspect ratio of the image will be maintained.

Returns

A pointer to the created EZ_image structure.

Return values

NULL	if the texture could not be created from the surface.

EZ_create_image_file()

EZ_image * EZ_create_image_file	(	char *	file,
		SDL_Renderer *	renderer,
		anchore_point	dst_anchore,
		int	auto_aspect )

Creates an EZ_image from a file.

This function loads an image from the specified file and creates an EZ_image structure that can be used for rendering with SDL.

Parameters

file	The path to the image file to load.
renderer	The SDL_Renderer to use for creating the texture.
dst_anchore	The anchore point for the destination.
auto_aspect	If non-zero, the aspect ratio of the image will be maintained.

Returns

A pointer to the created EZ_image structure.

Return values

NULL	if the image or texture could not be loaded.

EZ_edit_image()

void EZ_edit_image	(	EZ_image *	image,
		SDL_Surface *	surface,
		SDL_Renderer *	renderer,
		int	auto_aspect )

Edits an existing EZ_image with a new SDL_Surface.

This function updates an existing EZ_image structure with a new SDL_Surface, recreating the texture and optionally maintaining the aspect ratio.

Parameters

image	The EZ_image structure to edit.
surface	The new SDL_Surface to use for the image.
renderer	The SDL_Renderer to use for creating the new texture.
auto_aspect	If non-zero, the aspect ratio of the image will be maintained.
