ABSTRACT:
A technique is demonstrated for the output of fonts on high resolution output devices, such as phototypesetters in particular, in which a processor unit optically scales a digitally stored font, expands/condenses and generates a desired weight of the font to be distributed. Two previously generated master fonts with varying weights in a digitized contour coding are used, by which a majority of the contours of each letter are provided with delimiting discrete control points and additionally with instructions, such as those stipulated for "Intelligent Font Scaling". The output font with the desired weight is generated through linear interpolation between the two master fonts. To optically scale to the desired point size, the output font is re-scaled with a factor to the desired point size and the instructions are applied in order to steadily vary the stroke width of the letters, linearly re-scaled with the factor, in a primary pre-set factor dependency whereby the stroke width is increased for factors smaller than 1% and decreased for factors larger than 1%. The font is typographically correctly expanded and condensed, in that the optically scaled output font is brought to the desired width through linear expansion or condensation with a second factor, whereby the instructions are applied in order to hold the stroke width constant during linear expansion or condensation of the letters and in this way to only broaden or narrow the contours.
