Description of the information file storage capacity, the object described in the scaling process will lose detail or produce jagged.

Resolution and grayscale are the main parameters affecting the display. Image is suitable for the performance of a large number of details (such as light and dark changes, complex scenes, outlines rich in color) of the object, such as: photographs, drawings, etc., through the image of the software can be complex image processing to get a clearer image or produce special effects. Computer images can be divided into bitmap and vector graphics from the processing mode.
