.net 2.0 Image Transformation Helper
Author: Duray AKAR
Published: 4/26/2006 12:47 PM
Category: ASP.NET, C#, VS.NET
Summary: I have been using the most addvanced technology of all times, copy & paste, for my bitmap transformations. Recently I have wrapped my functions in a Helper class...

 

Bitmap transformations can be clumsy.

Here is a helper class that uses the namespaces below, and does most of the common image transformation tasks, including grayscale, (or REDscale for that matter :)), resize, append a border, draw one image on another etc... 

I will also post a sample ASP.NET page that utilizes this class in the future...

using System.Drawing;
using System.Drawing.Imaging;
using System.Drawing.Drawing2D;

Hope it helps.

 

PS: Getting the actual number of bytes is another tricky part. you cannot get it from the bitmap or image object, you need to save it to a temporary stream first, which I opt for NOT doing it for performance reasons.

If anybody is aware of a neat way, let me know.
