Required methods

fn rotozoom(
    &self,
    angle: f64,
    zoom: f64,
    smooth: bool
) -> Result<Surface, String>

Rotates and zooms a surface and optional anti-aliasing.

fn rotozoom_xy(
    &self,
    angle: f64,
    zoomx: f64,
    zoomy: f64,
    smooth: bool
) -> Result<Surface, String>

Rotates and zooms a surface with different horizontal and vertical scaling factors and optional anti-aliasing.

fn zoom(&self, zoomx: f64, zoomy: f64, smooth: bool) -> Result<Surface, String>

Zoom a surface by independent horizontal and vertical factors with optional smoothing.

fn shrink(&self, factorx: i32, factory: i32) -> Result<Surface, String>

Shrink a surface by an integer ratio using averaging.

fn rotate_90deg(&self, turns: i32) -> Result<Surface, String>

Rotates a 8/16/24/32 bit surface in increments of 90 degrees.
