PCB Genesis增加点阵字 实现原理

我们采用Genesis增加点阵字时，用Genesis增加Canned Text即可，但奥宝中文不支持，且字符种类是有限的呀

不过没关系，没有自己造呀。在这里我分享一种增加点阵字的实现方法

一.通过代码增加点阵字效果

二.实现代码

        private void button1_Click(object sender, EventArgs e)
        {
            add Add = new add();
            Font font = new Font("宋体", 12);
            Add.text_dot(font, "pcbren共赢加油");

        }

        public void text_dot(Font font, string text = "pcbren", double x = 0, double y = 0, double symbols_size = 500, string symbol = "r", double scale = 1)
        {

            y += 10;
            int txt_space = 12;
            double txt_sum = 0;
            foreach (char strt in text)
            {
                if (strt >= 0x4e00 && strt <= 0x9fbb)
                    txt_space = 12;
                else
                    txt_space = 8;
                bool[,] data = calc.text_dot_array(font, strt.ToString());
                for (int i = 0; i <= data.GetLength(0) - 1; i++)
                {
                    for (int j = 0; j <= data.GetLength(0) - 1; j++)
                    {
                        if (data[i, j])
                        {
                            pad(i * scale + txt_sum, y * scale - j * scale, symbols_size, symbol);
                        }
                    }
                }
                txt_sum += txt_space * scale;
            }
        }
