b2-xpm-sharp 0.0.1

This library loads XPM v3 files into XPixMap objects for reading purposes (writing XPM files might be added later). Currently there are three ways to load a XPM file:

• Call XPixMap.FromContent(string content) which takes the content of a XPM file.
• Call XPixMap.FromFile(string path) which takes the path to your XPM file.
• Call XPixMap.FromStream(Stream stream) which takes a readable stream, setting its position to zero. (Be sure to dispose the stream after calling the method.)

The XPixMap then can be used to get meaningful info about the XPM, like Width, Height, Hotspot (if present) and the pixel matrix by calling GetColors() returning a Color[,].
Additionally, the Extensions method GetBitmap() can be used to convert the XPM to a System.Drawing.Common.Bitmap object.

var xpm = XPixMap.FromFile(@"C:\path\to\image.xpm");
var bmp = xpm.GetBitmap();
//Edit the image
bmp.SetPixel(0, 0, Color.Black);
bmp.SetPixel(0, 1, Color.White);
//Save it
bmp.Save(@"C:\path\to\image.png", System.Drawing.Imaging.ImageFormat.Png);

There is also a DrawOn() extension method which allows you to draw the XPM on a surface. (For example, a windows form handle)

using var stream = openFileDialog.OpenFile();
var xpm = XPixMap.FromStream(stream);
xpm.DrawOn(Handle);

The library is on .netstandard so it's usable on .net and .net Framework. However I have not tested it on linux and it might not work as expected.
