Detailed Description

Function Documentation

◆ GPU_FreeRenderer()

DECLSPEC void SDLCALL GPU_FreeRenderer ( GPU_Renderer * renderer )

Definition at line 480 of file SDL_gpu_renderer.c.

◆ GPU_GetActiveRendererList()

DECLSPEC void SDLCALL GPU_GetActiveRendererList ( GPU_RendererID * renderers_array )

Gets an array of identifiers for the active renderers.

Definition at line 59 of file SDL_gpu_renderer.c.

◆ GPU_GetCoordinateMode()

DECLSPEC GPU_bool SDLCALL GPU_GetCoordinateMode ( void )

Definition at line 105 of file SDL_gpu.c.

◆ GPU_GetCurrentRenderer()

DECLSPEC GPU_Renderer* SDLCALL GPU_GetCurrentRenderer ( void )

Returns: The current renderer

Definition at line 113 of file SDL_gpu.c.

◆ GPU_GetDefaultAnchor()

DECLSPEC void SDLCALL GPU_GetDefaultAnchor	(	float *	anchor_x,
		float *	anchor_y
	)

Returns the default image blitting anchor through the given variables.

See also: GPU_GetAnchor

Definition at line 1915 of file SDL_gpu.c.

◆ GPU_GetNumActiveRenderers()

DECLSPEC int SDLCALL GPU_GetNumActiveRenderers ( void )

Gets the number of active (created) renderers.

Definition at line 43 of file SDL_gpu_renderer.c.

◆ GPU_GetRenderer()

DECLSPEC GPU_Renderer* SDLCALL GPU_GetRenderer ( GPU_RendererID id )

Returns: The renderer matching the given identifier.

Definition at line 411 of file SDL_gpu_renderer.c.

◆ GPU_ReserveNextRendererEnum()

DECLSPEC GPU_RendererEnum SDLCALL GPU_ReserveNextRendererEnum ( void )

Gets the next enum ID that can be used for a custom renderer.

Definition at line 37 of file SDL_gpu_renderer.c.

◆ GPU_ResetRendererState()

DECLSPEC void SDLCALL GPU_ResetRendererState ( void )

Reapplies the renderer state to the backend API (e.g. OpenGL, Direct3D). Use this if you want SDL_gpu to be able to render after you've used direct backend calls.

Definition at line 89 of file SDL_gpu.c.

◆ GPU_SetCoordinateMode()

DECLSPEC void SDLCALL GPU_SetCoordinateMode ( GPU_bool use_math_coords )

Sets the coordinate mode for this renderer. Target and image coordinates will be either "inverted" (0,0 is the upper left corner, y increases downward) or "mathematical" (0,0 is the bottom-left corner, y increases upward). The default is inverted (0), as this is traditional for 2D graphics.

Parameters

inverted 0 is for inverted coordinates, 1 is for mathematical coordinates

Definition at line 97 of file SDL_gpu.c.

◆ GPU_SetCurrentRenderer()

DECLSPEC void SDLCALL GPU_SetCurrentRenderer ( GPU_RendererID id )

Switches the current renderer to the renderer matching the given identifier.

Definition at line 81 of file SDL_gpu.c.

◆ GPU_SetDefaultAnchor()

DECLSPEC void SDLCALL GPU_SetDefaultAnchor	(	float	anchor_x,
		float	anchor_y
	)

Sets the default image blitting anchor for newly created images.

Definition at line 1906 of file SDL_gpu.c.
