PSAM Control Library is a WinForms library containing the IncipitViewer control for drawing musical notes which can be read from MusicXml file or added programmatically. The library was initially a component of larger software Polish System for Archivising Music but I thought it could be useful for other software developers so I decided to distribute it under BSD licence. PSAM Control Library is written in C# under Microsoft Visual Studio Express.

Improve drawing speed using layers in .NET

A common software-development task is generating a graph from a set of test-related data. But if you're doing it by hand and the underlying data changes frequently, this particular task can become quite tedious. James McCaffrey shows you how to automate the process using Windows Presentation Foundation technology.

It’s fairly easy to create and animate a graphical primitive, say by moving it from point A to point B at constant speed. But what if you need to position several graphical objects in a particular arrangement and then animate them in a non-linear fashion? Neither Silverlight nor WPF has built-in functions for this. In this article, I’ll demonstrate ways in which one can create objects and animations dynamically using lambda-delegates and higher-order functions.

Most of the implementations of JPEG Encoder/Decoder are in C/C++. But, for a project my friend 'anirban' required a JPEG Encoder in C#. So, we started writing our own encoder. It turned out to be very complex and difficult. The one we wrote from scratch was really-really slow.. some functions had 4th order complexity (Mostly the DCT part). Somehow, we managed to get some 'C' code from a forum. I converted parts of the 'C' code to C#, it was tedious work, but it worked pretty fast due to the fast DCT (AA&N).

Since OpenGL drawing commands are limited to those that generate simple geometric primitives (points, lines, and polygons), the OpenGL Utility Toolkit (GLUT) has been created to aid in the development of more complicated three-dimensional objects such as a sphere, a torus, and even a teapot. GLUT may not be satisfactory for full-featured OpenGL applications, but it is a useful starting point for learning OpenGL…

A program to produce beautiful and informative images of complex functions.

Simulating a random motion animation without code, using Spirographic Shapes, PathListBoxes, Storyboards & Behaviours

This C# program demonstrates the effect of using the ColorMatrix operator on an image. This program contains several sample matrix filters which you can select and modify. The top portion of the program interface contains three images. A background image, an overlay and the result of applying the color matrix on the overlay rendered on top of the background image.
