Text-moire' minimization

Abstract

Pixel-level monitoring and reconfiguring of both text inter-word spacing and individual character widths minimizes undesirable moire′ channels and moire′-glyphs, and more particularly relates to operator-selected automatic intra-word space manipulation and automatic intra-character width manipulation to achieve a pleasing overall page effect with maximized freedom from moire′-maze and moire′-glyph visual effects, both in proportional spaced fonts and fixed-character-width fonts. Selective scrolling may be by black-spot instead of actual characters, to make the white moire′-effects stand out more clearly. The typesetter may alternate positive and negative, which is another way to emphasize the moire′-effects. A further sub-variant, called “blush,” causes graying of spaces which are so surrounded by characters that they cannot participate in moire′-effects. This emphasizes the actual moiré-effects. The typesetter may “unselect,” by pointing a cursor at a moire′-effect and key + or − to accept the particular moire′-effect as benign, or to proceed with an amelioration procedure.
