Hi,

I'm trying to use ImageProcessor with the greyscale filter, but it throws an exception when using just the filter (?filter=greyscale). If I use other attributes, it no longer throws an exception, but does not apply the filter (?height=200&filter=greyscale).

My code to generate the url is as follows:

var imageUrl = image.GetCropUrl(300, 300, furtherOptions: "&filter=greyscale");

and this outputs the following url

http://localhost:49772/media/1262/chair.jpg?anchor=center&mode=crop&width=300&height=300&filter=greyscale&rnd=131491687990000000

This does return the image, but no filter is applied i.e. the image is still full colour.

If I query the image directly with just the filter as follows:

http://localhost:49772/media/1262/chair.jpg?filter=greyscale

then the server throws an exception....

Any one else experience this?
