Abstract
A printer embodied rendering algorithm for detecting and configuring positive and negative thin lines to be rendered such that when a bright-colored thin line on a dark background (negative thin line) is rendered and the result is stored in an RGB buffer in a printer system, the thin line thickness is increased only when the brightness of the line color is higher than a predetermined threshold value and the thin line thickness is smaller than a predetermined threshold value. According to the rendering algorithm, it is possible to prevent a negative thin line from disappearing or becoming thinner without increasing a positive thin line thickness, thereby improving the visibility of the thin line.
Claims15
A method to control printed line quality using a rendering algorithm, comprising the steps of:
- determining a thickness of a line to be rendered;
- determining a brightness of the line to be rendered;
- determining if the brightness of the line is greater than a first predetermined threshold value and if the thickness of the line is less than a second predetermined threshold value;
- and
- increasing the thickness of the line to be rendered if the brightness of the line is greater than the first predetermined threshold value and the thickness of the line is less than the second predetermined threshold value.
