HTJ2K decoding in the browser using WASM (with or without SIMD)

This webpage employs WASM SIMD if your browser supports it --> 

Decoding the full resolution image.

HTJ2K progressive decoding to the actual image resolution

This example shows that one source image can be used for multiple reconstructed resolutions.
The client/browser can decide, depending on the rendering resolution, the number of bytes to load and decode for a given image.

Note: Below each image, we display the number of decoded bytes

HTJ2K progressive decoding to full resolution (downloaded once, decoded many ways)

This example shows the progressive decoding of JPEG2000. 
Image quality improves as more data arrives. This is better than waiting for the whole image to arrive before decoding it.

Note: Below each image, we display the number of decoded bytes and PSNR.

Decoded Bytes: 826 bytes

Decoded Bytes: 2312 bytes

PSNR: 16.96 dB

PSNR: 18.25 dB
