Hi

I am working on C# program to process images ( given as int[,] )..
So I have 2D array of pixels, and I need to rotate them around a point, then scale them down to fit the original array..
I already found articles about using matrix to transform to a point and rotate then transform back..
What remains is to scale the resultant image to fit an array of original size..

How that can be done? (preferably with 2 equations one for x and one for y )

Thanks in advance

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More

I have a rectangle in SVG that I need to rotate on a pivot from a specific point. The best way I can see to do this is transform to the xy of the pivot, rotate the degree, and then transform again.
