Struct ResizeKernel 

pub struct ResizeKernel { /* private fields */ }

Image resize kernel

Implementations

impl ResizeKernel

pub fn new(filter: ResizeFilter) -> Self

Create a new resize kernel

pub fn execute( &self, device: &GpuDevice, input: &[u8], _src_width: u32, _src_height: u32, output: &mut [u8], dst_width: u32, dst_height: u32, ) -> Result<()>

Execute the resize operation

Arguments

• device - GPU device
• input - Input image buffer
• src_width - Source image width
• src_height - Source image height
• output - Output image buffer
• dst_width - Destination image width
• dst_height - Destination image height

Errors

Returns an error if the resize operation fails.

pub fn filter(&self) -> ResizeFilter

Get the filter type

pub fn output_size(dst_width: u32, dst_height: u32, channels: u32) -> usize

Calculate output buffer size

pub fn estimate_flops( _src_width: u32, _src_height: u32, dst_width: u32, dst_height: u32, filter: ResizeFilter, ) -> u64

Estimate FLOPS for the resize operation
