NAME

       SDL_UpdateTexture - Update the given texture rectangle with new pixel data.

SYNOPSIS

       #include <SDL3/SDL_render.h>

       bool SDL_UpdateTexture(SDL_Texture *texture, const SDL_Rect *rect, const void *pixels, int pitch);

DESCRIPTION

       The  pixel  data  must  be  in  the  pixel  format  of  the  texture,  which  can  be  queried  using the
       SDL_PROP_TEXTURE_FORMAT_NUMBER property.

       This is a fairly slow function, intended for use with static textures that do not change often.

       If the texture is intended to be updated often, it is preferred to create the texture  as  streaming  and
       use  the  locking  functions referenced below. While this function will work with streaming textures, for
       optimization reasons you may not get the pixels back if you lock the texture afterward.

FUNCTION PARAMETERS

       texture
              the texture to update.

       rect   an SDL_Rect structure representing the area to update, or NULL to update the entire texture.

       pixels the raw pixel data in the format of the texture.

       pitch  the number of bytes in a row of pixel data, including padding between lines.

RETURN VALUE

       for more information.

THREAD SAFETY

       This function should only be called on the main thread.

AVAILABILITY

       This function is available since SDL 3.2.0.
