I have an ImageFile from wich I'd like to generate 300px wide images. The problem is that the images that I get, they sure is 300px wide, but most of the image is wite space. The image itself is just about a ten pixels wide. Does anyone know what could cause this?

[ScaffoldColumn(false)]
[ImageDescriptor(Width = 300)]
public virtual Blob Image300 { get; set; }

...

var routeValues = new RouteValueDictionary();
routeValues["action"] = "Image300";
var imagePath = _urlResolver.Service.GetVirtualPath(media.AssetLink, null, new VirtualPathArguments() { RouteValues = routeValues });
