Title (EN) REPRODUCTION OF CHARACTER IMAGES,PARTICULARLY FOR TYPESETTING APPARATUS
(FR) REPRODUCTION D"IMAGES DE CARACTERES, EN PARTICULIER POUR COMPOSEUSE
Abstract: front page image
(EN)Character images are recreated and displayed on an incrementing plotter, such as a cathode ray tube (92), with a smoothly continuous outline and not as a discontinuous assembly of stripes or dots. A master curve, e.g. a spiral, is stored electronically in a memory (16) as a sequence of vector step p instructions. The sequential outline is achieved by selecting appropriate curve sections from the memory to match the desired outline and re-orientating these curve sections so that successive sections join perfectly. The image can be displayed as designed, or one can add, subtract or modify elements of the character instantaneously. The system is especially suited for typesetting. For this, the system m provides for infilling of the outline; for smoothing the curve; for thickening vertical and/or horizontal elements of a character; for vertically compressing zones of a character; and for tracing a secondary outline just inside the main outline.
(FR)Des images de caracteres sont reproduites et projetees sur un traceur a e increments tel qu"un tube a rayons cathodiques (92), avec un contour continu egalise et non pas avec un assemblage discontinu de traits ou pointilles. Une courbe maitresse, par exemple une spirale, est emmagasinee electroniquement dans une memoire (16) comme sequence d"instructions a pas vectorises. Le contour continu est obtenu en selectionnant des sections de courbes appropriees de la memoire pour les faire coincider avec le contour desire et reorienter ces sections de courbe de sorte que les sections successives se joignent parfaitement. L"image peut etre projetee telle qu"elle est dessinee ou on peut ajouter, soustraire, ou modifier des elements du caractere instantanement. Le systeme est specialement adapte a la composition. A cet effet, le systeme assure le remplissage du contour, l"egalisation de la courbe, l"epaississement d"elements verticaux et/ou horizontaux d"un caractere, la compression de zones verticales d"un caractere, et le tracage d"un contour secondaire juste a l"interieur du contour principal.
