Hi all,

Hoping somebody can help me, I've got my SharpMap ASP.NET site nearly working how I want it now.

It has an ImageButton, which, using the SharpMap GdalRasterLayer and HttpHandler, displays a section of a 4MB TIF file from cache. At the moment this seems to be about 350KB in size, which is quite a large amount of data to transfer across the network in what I would like to be a fast site.

I am likely going to implement a bit of JavaScript to preload the image in the browser to stop it scanning slowly down like it does at present but what I would ideally like to do is convert the image being sent to a smaller file size before it is sent to the client... is this possible? The server it's running on is a beast.. so the bottleneck at the moment is definitely the size of this image

You can use application state, session state or caching mechanisms to retrieve the data once and use it later. Choose which best fits your need among the three.
