An image processing system utilizes an image type classification circuit to identify inputted image data as picture image data or text/graphics image data. A halftone circuit, operatively connected to the image type classification circuit, converts the inputted image data, identified as picture image data, to halftone image data. Moreover, a tile pattern circuit, operatively connected to the image type classification circuit, to replace the inputted image data, identified as text/graphics image data, with tile patterns. The tile patterns are encoded with a predetermined pattern. A bitmap rendering circuit combines the halftone image data with the encoded tile patterns to render a bitmap, wherein the bitmap can be used by a print engine to reproduce the image.
