Image Resizer : API Documentation

Fired once, on the first PostAuthorizeRequest event.

Fires during the PostAuthorizeRequest phase, prior to any module-specific logic. Executes for every request to the website. Use only as a last resort. Other events occur only for image requests, and thus have lower overhead.

Fired during PostAuthorizeRequest, after ResizeExtension has been removed. On fired on requests with extensions that match supported image types.

You can add additonal supported image extentions by registering a plugin that implementes IQuerystringPlugin, or you can add an extra extension in the URL and remove it here. Example:.psd.jpg

Fired during PostAuthorizeRequest, after Rewrite. Any changes made here (which conflict) will be overwritten by the the current querystring values. I.e, this is a good place to specify default settings.

Only fired on accepted image types. (see Rewrite)

Fired after all other rewrite events.

Only fired on accepted image types. (see Rewrite)

Fired after all rewriting is finished. e.AllowAccess defaults to the result of the UrlAuthorization module's verdict. It can be changed. Set e.AllowAccess to true to cause and 403 Access Dened result.

Fired when the specified image doesn't exist. Only called for images that would normally be processed. May be called during PostAuthorizeRequest or later - End the request completely with a redirect if you want alternate behavior.

Fired immediately before the image request is sent off to the caching system for proccessing. Allows modification of response headers, caching arguments, and callbacks.

Returns a unqiue copy of the image extensions supported by the pipeline. Performs a cached query to all registered IQuerystringPlugin instances. Use IsAcceptedImageType for better performance.

Cached access to pipeline.fakeExtensions

Returns true if the current request is being processed and/or cached by the pipeline. Will return false until *after* the FileExists method is called on the VirtualPathProviders, which is after the AuthorizeImage event fires. This will return a usable value if used from VirtualFile.Open(), or if used inside the PreHandleImage event or later.

Returns the modified query string. If never set, returns a copy of Request.QueryString. Returns the same instance if called multiple times. Copy it if you want to make changes without causing issues.

True once the InterceptModule has been installed and is intercepting requests.

Returns the value of Context.Items["resizer.newPath"] if present. If not, returns FilePath + PathInfo. Sets Context.Items["resizer.newPath"]. Only useful during the Pipeline.PostAuthorizeRequestStart event.

The number of images processed by this pipeline.

Get or sets whether the file extension check should be applied to the current request. Defaults to true. If set to true, will only affect the current request, and will only cause the Resizer to evaluate the rewriting rules on the request. Processing may still not occur if no querystring values are specified. Add 'cache=always' to force caching to occur.

Returns a unqiue copy of all querystring keys supported by the pipeline. Performs a cached query to all registered IQuerystringPlugin instances. Use HasPipelineDirective for better performance. (binary search)
