Not possible to use webp plugin using instructions in documentation #246

Open LinusEkstrom opened 5 years ago

LinusEkstrom commented 5 years ago

I've been trying to get the Webp-pluging to work for a solution based on ImageResizer.Net with an elite license, but can't get it to work. As been mentioned in previous issue, this has a dependency to a non-documentet external assembly. This is available on Nuget as a redistributable version, but for an older version of .NET framework. Regardless, I've gotten hold of a version of libwebp.dll but I'm getting a BadImageException when trying to convert an image from png to webp with the following stack trace:

We've managed to get it up and running, after a bit of a struggle, on our side maybe 6 months ago. Not sure these are all the bits and pieces that need to be in place but just thought we could compare environments:
