Abstract

PURPOSE:To display necessary attributes even for characters which differ in size by storing identification codes of attributes given to characters and patterns of the attributes for the identification codes, and displaying the patterns of attributes corresponding to specified identification codes for characters within a specified rectangular range. CONSTITUTION:This circuit is provided with an attribute table 1 which contains the coordinate values of the left upper point and right lower point indicating the rectangular range on the screen of a display device and the identification codes indicating attributes given to characters within the rectangular range and an attribute pattern storage area 2 stored with patterns corresponding to all the identification codes. A corresponding pattern is selected in the attribute pattern storage area 2 by referring to the identification code of the kind of the attribute given to a character in the rectangular range specified in the attribute table 1, and the coordinate values of the rectangular range are read out of the attribute table 1, sent out to a display device together with the pattern that a selecting circuit 3 selects, and displayed. Consequently, the attributes for characters of different size are displayed.

In the conventional character attribute display circuit as described above, when the size of the character is constant and the display device is also at a fixed position on the screen, the character attribute is represented by a graphic of the attribute using an identification code. However, when displaying characters with different sizes and setting attributes for them, the size and position of the attributes must also be changed to correspond to the characters to which the attributes are attached. Therefore, management using only identification codes representing types has the disadvantage that attributes cannot be set for characters of different sizes.

In FIG. 1, an attribute table 1 indicates a storage format in a storage device that stores information regarding the attributes of characters displayed on the screen of a display device. The data stored here are coordinates indicating a rectangular range on the screen and identification codes indicating attributes of characters within the range. The attribute pattern storage area 2 is an area of the storage device that stores graphics of attributes to be displayed on the screen. The selection circuit 3 is a circuit that selects a figure corresponding to a designated identification code from among all the figures of attributes stored in the attribute pattern storage area 2. The transfer circuit 4 is a circuit that displays the figure selected by the selection circuit 3 from the attribute pattern storage area 2 in a rectangular range of the screen of the CRT 5 specified in the attribute table 1.
