func WritePNG ¶

func WritePNG(w io.Writer, p *chess.Position, markedSquares ...chess.Square) error

WritePNG writes a 500x500 pixel PNG of the position to the writer. Any markedSquares will be highlighted in the resulting image. This function is dependent on rsvg-convert which is installed with apt-get install librsvg2-bin on debian systems. An error will be return if there is a problem reading from or writing to the filesystem (filesystem access is required to use rsvg-convert).
