Embodiment Construction
[0059] The implementation process of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0060] A method for drawing complex Braille dot matrix graphics and inputting embedded characters of the present invention includes drawing and conversion of multi-order Bezier curves; conversion of pictures to Braille dot matrix; and three items of method for inputting embedded Braille characters; Through the input of these three types of content, the drawing of Braille dot matrix graphics is as simple and intuitive as normal graphics.
[0061] The drawing examples of these three types of graphics are illustrated below:
[0062] Such as figure 1 Shown is a schematic flow chart of the drawing and conversion method of multi-order Bezier curves, including the following steps:
[0063] 1) The starting position point P of the record curve 0 , end point P n (n>=2);
[0064] 2) Record the first inflection point P of the c...
