This article describes an approach to constructing a cool segmented LED displayer that is similar to the LEDs used in alarm clocks and industry monitors. This control can be used to display time, numerical values and even some English characters. I hope it will be helpful in programs such as hardware simulators.

This is a very simple article that really just demonstrates the various capabilities of the WPF ImageBrush. The basic idea is that the attached demo emulated one of those 9 square puzzles you used to get in XMAS stockings.

This article addresses the construction of a simple graph library using C#.

The controls in Windows Forms (.NET) don't support true transparency. In this article we show how to use transparent labels and images.

Arcball (also know as RollerBall) is probably the most intuitive method to view three dimensional objects. The principle of the arcball is based on creating a sphere around the object, and let users to click a point on the sphere and drag it to a different location. There is a bit of math involved of course and you can Google it. The code here is a C# source code implementing an arcball in OpenGL (CsGL to be exact).

A texture transfer program that implements Efros & Freeman's texture transfer algorithm

After growing tired of spending hours zoomed in at 800% magnification using the polygon lasso tool to create combined grayscale and color images in Macromedia Fireworks, I decided that there had to be a better way. Thus I embarked upon creating this application to make my life and hopefully that of others easier.

This article shows how to generate some column chart images for your users on a easy way. You can simply give some arguments to the class library and receive back an image object, or directly save it on hard disk.

My goals for this library were to make it easy to use, and flexible enough to be used no matter how you store your images (FileSystem, Database, Amazon Web Services, etc). As for the discussion on which way is the "best" way to store images - I'll leave that to someone else. However, anyway you go, there's still some common things you have to think about: resizing images and maintaining aspect ratio, uniqueness of file names, etc.

Have you ever had the need to generate images on the fly in your ASP.NET applications? You could use GDI.NET to do this directly, but we think we have an easier way. Enter ImageTemplate.NET. ImageTemplate.NET lets you configure an image template in an XML file and then change the image that is generated by passing parameters in the URL.
