Required Methods§

source

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

Rotates and zooms a surface and optional anti-aliasing.

source

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.

source

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

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

source

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

Shrink a surface by an integer ratio using averaging.

source

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

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