Abstract:
1. A method of displaying strokes on a display, comprising: receiving stroke data; rendering the stroke data into an ink buffer at a higher resolution than the display, the ink buffer including elements that correspond to pixels, each element including bits that correspond to a plurality of subpixels of each pixel; organizing the bits from highest to lowest importance including discarding a portion of the bits based on the organization and a difference between resolutions of the stroke data and the ink buffer; computing pixel colors by counting a number of the bits in each element that are set to a given value and performing compositing based on a background color of each pixel and the number of the bits, wherein performing compositing comprises multiplying luminance of the background color by the number of the bits; and generating on the display an anti-aliased visual display of the stroke data based on the pixel colors.
