ABSTRACT:
An image-memory stores image data in a form such that the thus stored image data may be used for realizing the corresponding image on a recording medium. A straight-line-vector processing unit processes straight line vectors associated with image data provided thereto so that the resulting data may be used to be stored in the image-memory. A data switching unit switches so that either the data obtained from the straight-line-vector processing unit may be stored in the image-memory or data obtained from an image inputting unit may be stored in the image-memory. A data expanding unit expands the image data provided from a host computer into the corresponding main-scan-direction straight line vectors. A data generating unit generates the start and end addresses associated with the straight line vectors and the relevant density values associated with the image data. The image-memory comprises areas, each provided for a respective basic color component associated with the data to be stored, for storing either single tone values or multi-tone values. An image rendering unit writs the image data in each dot in the image-memory means based on the data provided by the straight-line-vector processing means. The image inputting unit comprises an image scanner.
