I have a configuration file where a developer can specify a text color by passing in a string: <text value="Hello, World" color="Red"/> Rather than have a gigantic switch statement look for all of the possible colors, it'd be nice to just use the properties in the class System.Drawing.Brushes instead so internally I can say something...

Where can I find out enough info about how Brushes work to implement my own System.Windows.Media.Brush? I can handle all of the freezable baggage, but it's not really obvious what I need to override to get it to work. Yeah, so I didn't mean that I want to use a predefined brush. I want to extend System.Windows.Media.Brush, which is ...
How might I create a brush that paints a regular, repeated grid of 1-unit thick lines spaced evenly in both the horizontal and vertical axes? Imagine graph paper, if you will.

On the Nerd Plus Art blog today, there was a post about creating WPF Resources for arrows, which the author uses frequently.

I added the LeftArrow and RightArrow Geometries to my application's resources...

In Silverlight (version 3 preview), I want to create a Line with different solid colors, so no gradients between colors. Basically I want to do the following: <Line X1="0" X2="500" StrokeThickness="10"> <Line.Stroke> <LinearGradientBrush> <GradientStop Color="Blue" Offset="0.5" /> <GradientStop Color="Red" Offset="1"/> </LinearGr...
To draw a circular part of a bitmap on the screen, I use a PatternBrush created from the bitmap to fill an ellipse. I use P/Invoke to the native functions because there seems to be a bug in CF2.0 if you use the managed functions (see here for more details: http://social.msdn.microsoft.com/forums/en-US/netfxcompact/thread/e831ea2f-039a-4b...

Hi, the following code is fairly straight forward - it fills a design surface with randomnly selected pixels - nothing special (ignore the XXXXXXX's in the 2nd method for now). private void PaintBackground() { Random rnd = new Random(); Bitmap b = new Bitmap(this.Width, this.Height); for (int vertical = 0; vertical < this.H...

Suppose I had two brushes. One that was a linear gradient brush that was from Dark to light One was a radial brush that went from Dark to light.

After applying a relative rotate transform (of 45 degrees) on a brush in WPF, I am left with extremely jagged lines. Has anyone else experienced this? Did you find a solution? ...
I have a VB6 application (please don't laugh) which does a lot of drawing via BitBlt and the standard VB6 drawing functions. I am running up against performance issues (yes, I do the regular tricks like drawing to memory). So, I decided to investigate other ways of drawing, and have come upon OpenGL. I've been doing some experimenting...
