Crate compeg

WebGPU compute shader JPEG decoder.

Usage:

• Create a Gpu context (either automatically via Gpu::open or from an existing wgpu context via Gpu::from_wgpu).
• Create a Decoder (or multiple) via Decoder::new.
• For each JPEG image you want to decode, create an ImageData object and pass it to Decoder::start_decode.
  • The Decoder will automatically resize buffers and textures when they are too small for the passed ImageData.
• Access the output Texture via DecodeOp::texture.
  • wgpu will automatically ensure that the proper barriers are in place when this Texture is used in a GPU operation.

Structs

DecodeOp

Information about an ongoing JPEG decode operation.

Decoder

A GPU JPEG decode context.

Gpu

An open handle to a GPU.

ImageData

A parsed JPEG image, containing all data needed for on-GPU decoding.
