Rotate images to straighten them in C#
I’ve written a couple of examples that show how to rotate images. I made many of them because I wanted to adjust a picture I had taken that was slightly crooked. Those examples work well, but they can be fairly … Continue reading
Find drawn characters under the mouse in C#
The following examples find the positions of drawn characters in a string that is drawn by using the Graphics object’s DrawString method. Measure character positions in a drawn string in C# Measure character positions when drawing long strings in C# … Continue reading

Let the user draw rotated skewed polygons in C#
The example Let the user draw rotated polygons with right angles in C# draws polygons with edges that are parallel or perpendicular to a baseline. This example is very similar except its polygons have edges that are parallel to one … Continue reading
Let the user draw rotated polygons with right angles in C#
This example lets the user draw rotated polygons where all edges are either parallel or perpendicular to a defined baseline direction. As a result, all of the polygon’s angles are right angles. (And yes, I know that the polygons aren’t … Continue reading
Draw interlocked circles in C#
This example draws a set of interlocked circles so they alternate between above and below each other. As you can see from the picture, the circles are made up of colored lines with black outlines so it’s easy to see … Continue reading
