context: &mut RCHandle<GrRecordingContext>,
backend_texture: &RefHandle<GrBackendTexture>,
origin: GrSurfaceOrigin,
sample_cnt: impl Into<Option<usize>>,
color_type: ColorType,
color_space: impl Into<Option<RCHandle<SkColorSpace>>>,
surface_props: Option<&SurfaceProps>,
) -> Option<RCHandle<SkSurface>>Expand description
Wraps a GPU-backed texture into Surface. Caller must ensure the texture is
valid for the lifetime of returned Surface. If sample_cnt greater than zero,
creates an intermediate MSAA Surface which is used for drawing backend_texture.
Surface is returned if all parameters are valid. backend_texture is valid if
its pixel configuration agrees with color_space and context; for instance, if
backend_texture has an sRGB configuration, then context must support sRGB,
and color_space must be present. Further, backend_texture width and height must
not exceed context capabilities, and the context must be able to support
back-end textures.

Returns: Surface if all parameters are valid; otherwise, None
