Struct Resizer 

pub struct Resizer { /* private fields */ }

Methods of this structure used to resize images.

Implementations

impl Resizer

pub fn new() -> Self

Creates an instance of Resizer.

By default, an instance of Resizer is created with the best CPU extensions provided by your CPU. You can change this by using the method Resizer::set_cpu_extensions.

pub fn resize<'o>( &mut self, src_image: &impl IntoImageView, dst_image: &mut impl IntoImageViewMut, options: impl Into<Option<&'o ResizeOptions>>, ) -> Result<(), ResizeError>

Resize the source image to the size of the destination image and save the result to the latter’s pixel buffer.

pub fn resize_typed<'o, P: PixelTrait>( &mut self, src_view: &impl ImageView<Pixel = P>, dst_view: &mut impl ImageViewMut<Pixel = P>, options: impl Into<Option<&'o ResizeOptions>>, ) -> Result<(), ResizeError>

Resize the source image to the size of the destination image and save the result to the latter’s pixel buffer.

pub fn size_of_internal_buffers(&self) -> usize

Returns the size of internal buffers used to store the results of intermediate resizing steps.

pub fn reset_internal_buffers(&mut self)

Deallocates the internal buffers used to store the results of intermediate resizing steps.

pub fn cpu_extensions(&self) -> CpuExtensions

pub unsafe fn set_cpu_extensions(&mut self, extensions: CpuExtensions)

Safety

This is unsafe because this method allows you to set a CPU extension that is not supported by your CPU.
