ABSTRACT:
A printer controller wherein original outline data representative of the outline of a figure are converted by an approximating device into approximative outline data including straight segment data representative straight segments which approximate curved segments of the original outline. The approximating device is adapted to lower the accuracy of approximation of the curved segments by the straight segments, until the amount of the approximation data is reduced to such an extent that the approximative data can be entirely stored in a currently available empty area of a random-access memory, before the approximative data are converted into bit map data representative of image dots filling the interior of the figure outline.
