- update-yuv-texture-raw! texture rect y-plane y-pitch u-plane u-pitch v-plane v-pitchprocedure
Overwrite part or all of a YV12- or IYUV-formatted texture's pixel data. This is for advanced users, and must be used with caution. See SDL_UpdateYUVTexture.
- texture is the sdl2:texture that you wish to update
- rect is either an sdl2:rect (to update part of the texture), or #f (to update all of the texture)
- y-plane is a pointer or locative to raw pixel data for the Y plane
- y-pitch is an integer describing the pitch of the Y pixel data
- u-plane is a pointer or locative to raw pixel data for the U plane
- u-pitch is an integer describing the pitch of the U pixel data
- v-plane is a pointer or locative to raw pixel data for the V plane
- v-pitch is an integer describing the pitch of the V pixel data
Signals an exception of kind (exn sdl2) if an error occurs.
Requires SDL 2.0.1 or higher, and sdl2 egg 0.2.0 or higher.
