Expand description

VipsInterpolate struct wrapping libvips VipsInterpolate

§Example

use vips::*;

fn main() -> Result<()> {
    let _instance = VipsInstance::new("app_test", true)?;
    let interpolate = VipsInterpolate::bilinear_static();
    let method = interpolate.method();
    let img = VipsImage::from_file("examples/images/kodim01.png")?;
    let region = VipsRegion::new(&img);
    let mut out = vec![0u8; 3]; // assuming 3 channels
    method.call(&interpolate, &region, &mut out, 1.5, 1.5);
    Ok(())
}
