SDL_QueryTexture

Query the attributes of a texture.

Syntax

int SDL_QueryTexture(SDL_Texture * texture,
                     Uint32 * format, int *access,
                     int *w, int *h);

Function Parameters

texture

the texture to query

format

a pointer filled in with the raw format of the texture; the actual format may differ, but pixel transfers will use this format (one of the SDL_PixelFormatEnum values). This argument can be NULL if you don't need this information.

access

a pointer filled in with the actual access to the texture (one of the SDL_TextureAccess values). This argument can be NULL if you don't need this information.

w

a pointer filled in with the width of the texture in pixels. This argument can be NULL if you don't need this information.

h

a pointer filled in with the height of the texture in pixels. This argument can be NULL if you don't need this information.

Return Value

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

Version

This function is available since SDL 3.0.0.

Code Examples

SDL_Texture* source;

// loading etc ...

int w, h;
SDL_QueryTexture(source, NULL, NULL, &w, &h);
