Abstract
Abstract An electronic graphic system is suitable for use in modifying data defining an initial high resolution image. In the system data relating to a user defined low resolution control image controls the combining of other image data with data defining a low resolution representation of the initial image. In this way the system produces data representing a low resolution combined image which is continously displayed on a display monitor. Once desired modifications have been achieved by the user to the image displayed on the display monitor, the low resolution control image data is converted into a high resolution representation. The high resolution control image is used to control the combining of the other image data with the initial high resolution image data to produce data defining a modified high resolution image. The other image data may be a user defined color or another image, for example.
