Is there a way to save an uncompressed image with libwebp?

[foogle]

When I save an uncompressed PNG of 1920x1080 size, it is about 8MB total size.

I am trying to do the same with libwebp but cannot manage to get files of anything like that size.

The reason I am trying to do this is performance.  I am wanting to do webp encoding with no compression at all, because compression is very CPU intensive.  I don't care the size, I am wanting the very fastest possible webp encoding.

Any suggestions?

thanks

I suppose there's a format or parameters to set for no compression, but you could easily invent your own: a few bytes of metadata at the start (pixel width, height, bytes/pixel, RGBwhatever, then followed by your raw data.

If you want no compression, you can go with https://en.wikipedia.org/wiki/Netpbm#File_formats or https://en.wikipedia.org/wiki/BMP_file_format

WebP does not allow that feature, it always compresses using the WebP format.

With cwebp, you can speed up compression by using the flags "-m 0 -mt" (no effort and multi-threading) for lossy or ("-z 0 -mt) with lossless.
