Fast, simple Bitmap editor class

Hello, my name is Rui Carvalho and I'm a Math teacher in Portugal. I Studied in 'Faculdade de Ciências da Universidade do Porto' and I've been programming since I was 16 years old. I'm an algorithms expert. I started in my CASIO calculator and then moved up to Visual Basic 6 (in my lovely Pentium 233 Mhz). Then I learned JAVA and c# as soon as possible. I've been programming in c# since then. For my databases I use SQL server and MySQL. I teach JAVA, C#, T-SQL to software developers (between my Math classes).
I worked in a software company for 3 years and I loved it. I spent those 3 years changing the base routines from VB6 to C# in many applications. I learned a lot about Taxes, Billing, Payments, Production,Company Management, Server Management,Synchronization,FTP, etc...
Today, unfortunately, I'm unemployed.
(Portugal is living a very very bad economic crisis)
