Having an image with a WMS enabled, creates services that supports several image formats:

<Format>image/png</Format>

<Format>image/png8</Format>

<Format>image/jpeg</Format>

<Format>image/jpegxr</Format>

<Format>image/webp</Format>

I have some questions regarding the WebP format:

1. Is this file format equivalent to the delivered imagery by the ECWP protocol?
2. What is being consumed by a desktop app when adding image with ECWP service enabled - ECWP or Webp?

Hi Eran,

WebP can be probably rather compared to JPEG or PNG - it is possible to select if you wish to use lossy or loss-less compression when saving image in that format. It uses different kind of compression algorhitm than ECW - the final image quality may depend on compression settings and subjective visual comparison. I haven't seen very wide usage of this format though...

Desktop App uses ECWP protocol, it has no support for WebP format.
