Initial commands

It is clever not to use absolute dimensions in the drawings. If we measure everything as a multiple of a unit length, we can easily scale the whole font. The unit length should be specified in sharp units (designated with `#12#) which are device independent. We must then convert it into device dependent number of pixels by calling define_pixels. To do this, ${\logo META}$ ${\logo FONT}$ must know the properties of the output device. To set everything up, you should call mode_setup at the very beginning and supply the correct mode when you call ${\logo META}$ ${\logo FONT}$ .

It may be interesting to see on screen how ${\logo META}$ ${\logo FONT}$ is drawing the picture. It is accomplished by screenstrokes. The beginning of ${\logo META}$ ${\logo FONT}$ source file may therefore look as:
