摘要:
Method and apparatus for creating multi-gradation data. The method and apparatus generates data having pixel values for respective pixels which comprise each of a plurality of characters in a font, and divides the respective pixels into a plurality of unit regions, a number of the respective pixels being obtained by multiplying a desired number of pixels by a number of pixels included in one unit region of the plurality of unit regions; extracts, for every unit region of the plurality of unit regions, the generated data; generates a multi-gradation data including a plurality of gradation values each gradually representing a different pixel brightness value, by converting, for every unit region, the data into the multi-gradation data in accordance with a plurality of pixel values included in the extracted unit region; and reduces the number of the respective pixels to the desired number of pixels by representing each unit region including the number of pixels with one pixel having a pixel value determined in accordance with the multi-gradation value.
