Graphics scaling method for high resolution printers
Abstract:
The invented method scales a graphics image by recognizing under what resolution the image was created, identifying the resolution of the printer that will actually print the image, calculating a convenient virtual resolution, approximating, on a pixel-by-pixel basis, using the virtual resolution, how many new pixels are required to emulate each existing pixel and then storing the new pixels in memory or printing them.
