Image forming device for processing a file containing raster data and vector data

摘要

An image forming device for forming images based on a file configured of a first data area for storing raster data and a header for storing vector data. The image forming device includes a raster data image displaying function for forming images on a display screen based on the raster data; and a vector data displaying function for forming images on the display screen based on the vector data. With this construction, the image forming device can easily manipulate both vector data and raster data by combining both types of data in one file. The image forming device can rapidly combine both types of data in one image by using vector data in parts requiring high image quality and raster data in parts requiring high-speed drawing.
