Title (EN) METHOD AND APPARATUS FOR RENDERING A VISUAL REPRESENTATION OF A FONT GLYPH
(FR) PROCÉDÉ ET APPAREIL DE RENDU D'UNE REPRÉSENTATION VISUELLE D'UN GLYPHE DE POLICE
Abstract:
(EN) A method for rendering a visual representation of a font glyph, the method comprising computing a set of straight or curved lines, wherein the straight or curved lines correspond to edges of the font glyph, computing a grid of cells overlaying the straight or curved lines, and then rendering each pixel by generating an ellipse, computing a ray that intersects a centre of the ellipse, calculating a coverage value, and using the coverage value to calculate a colour value for each pixel.
(FR) L'invention concerne un procédé de rendu d'une représentation visuelle d'un glyphe de police, le procédé comprenant le calcul d'un ensemble de lignes droites ou courbes, les lignes droites ou courbes correspondant à des bords du glyphe de police, le calcul d'une grille de cellules recouvrant les lignes droites ou courbes, puis le rendu de chaque pixel par production d'une ellipse, le calcul d'un rayon qui coupe un centre de l'ellipse, le calcul d'une valeur de couverture, et l'utilisation de la valeur de couverture pour calculer une valeur de couleur pour chaque pixel.
