Cogl.wayland_texture_set_region_from_shm_buffer

function wayland_texture_set_region_from_shm_buffer(texture: Cogl.Texture, src_x: Number(gint), src_y: Number(gint), width: Number(gint), height: Number(gint), shm_buffer: void, dst_x: Number(gint), dst_y: Number(gint), level: Number(gint)): Cogl.Bool {
    // Gjs wrapper for cogl_wayland_texture_set_region_from_shm_buffer()
}
  

Sets the pixels in a rectangular subregion of texture from a Wayland SHM buffer. Generally this would be used in response to wl_surface.damage event in a compositor in order to update the texture with the damaged region. This is just a convenience wrapper around getting the SHM buffer pointer and calling Cogl.Texture.prototype.set_region. See that function for a description of the level parameter.

<note>Since the storage for a Cogl.Texture is allocated lazily then if the given texture has not previously been allocated then this api can return false and throw an exceptional @error if there is not enough memory to allocate storage for texture.</note>
