Definition

Namespace

GleamTech.ImageUltimate.AspNet

Assembly

GleamTech.ImageUltimate.dll

Renders an image element with a unique and browser-cacheable url for the processed image. The first time this method is called, the image will be processed and cached on the server. The url will vary according to the processing commands so browser cache will be updated automatically when you change the parameters.

If the given path is rooted (eg ~/Picture.jpg, /SomeFolder/Picture.jpg or C:\SomeFolder\Picture.jpg), the exact path will be used, ie. the default source path will be ignored.

action Action<ImageWebTask>

The method for processing the image. This is usually a lambda expression which chains image processing commands.
