More performant way to redner a cliped region of image

[tsinjue]

HI, All,
I'am trying to using egui render images, I have a need to render a sub area of the image. for example, a cliped region of an image or just want the image from a start position.

The following code is my way( I want an sub area from the position [100, 200]),

if let Some(handle) = self.texture_handle.as_mut() {
        let image_data = self.image_data.clone().unwrap();
        handle.set_partial([100usize, 200], image_data, self.texture_options);
        ui.image(SizedTexture::from_handle(&handle));

but it panics, the panic info
TextureHandle.set_partil panics in wgpu. here is detailed info:
size: [
3248,
2432,
]thread 'main' panicked at wgpu-22.1.0/src/backend/wgpu_core.rs:3411:5:
wgpu error: Validation Error
Caused by: In Queue::write_texture Copy of X 100..3348 would end up overrunning the bounds of the Destination texture of X size 3248

Do I have to reprocess the Texture to update the size to [3148, 2232]? or any one has a convinient way to do this?
