Chess pieces of the Warlord chess program by William H. Rogers.
The chess pieces are stored in the file warlord.txt.
The repository includes a Lazarus project (using BGRABitmap library) for converting the text file to a bitmap.
There is another Lazarus project for cutting the bitmap into individual transparent PNG images.
The repository also includes a FreeBASIC chessboard demo using the Warlord chess pieces.
The Warlord chess pieces are used in Eschecs FreeBASIC.
