Klin Zha SVG Board Generator
The board is specified in SVG with 99.999% precision. It is not required, but if you're curious about the process, a page with a fair amount of the math that goes into the board generator is available.
Though it isn't obvious, the triangle pictured on the page below is a button to change from portrait orientation to landscape orientation, and the triangle width and height are tied together so setting one changes the other to keep the proportions correct.
NB: If you are getting these images for the screen, the page size is irrelevant; use any size you want.
