SDL_CreateTextureFromSurface

Create a texture from an existing surface.

Header File

Syntax

SDL_Texture* SDL_CreateTextureFromSurface(SDL_Renderer *renderer, SDL_Surface *surface);

Function Parameters

renderer	the rendering context
surface	the SDL_Surface structure containing pixel data used to fill the texture

Return Value

Returns the created texture or NULL on failure; call SDL_GetError() for more information.

Remarks

The surface is not modified or freed by this function.

The SDL_TextureAccess hint for the created texture is SDL_TEXTUREACCESS_STATIC.

The pixel format of the created texture may be different from the pixel format of the surface. Use SDL_QueryTexture() to query the pixel format of the texture.

Version

This function is available since SDL 3.0.0.

Code Examples

SDL_Renderer *renderer;

SDL_Surface *surface = SDL_CreateSurface(640, 480, SDL_PIXELFORMAT_RGBA8888);

if (surface == NULL) {
    fprintf(stderr, "CreateRGBSurface failed: %s\n", SDL_GetError());
    exit(1);
}

SDL_Texture *texture = SDL_CreateTextureFromSurface(renderer, surface);

if (texture == NULL) {
    fprintf(stderr, "CreateTextureFromSurface failed: %s\n", SDL_GetError());
    exit(1);
}

SDL_DestroySurface(surface);
surface = NULL;
