Abstract
Methods of performing stroke-to-raster video conversion having leading-edge error correction and/or falling-edge error correction are provided. Incoming data is pipelined before being written into a frame buffer. This allows each sample of data to be manipulated based on information obtained in samples that occur both before and after it. Highly accurate digital conversion of stroke video into a raster format having significantly reduced or eliminated noise and stray pixels from the video is therefore achieved.
