点阵字符的显示程序：用0和1来标识位图中的每个象素，对应于0的象素着背景色，对应于1的象素着前景色。一个点阵字符可以由一个数组来存储，即存储这个字符的位图，为了节省空间，可以采用16进制的数组来存储。显示字符的方法就是先判断位图中象素的标识是0还是1，然后把对应于1的象素它显示出来，而对应于0的象素不显示。-Character dot matrix display program: with 0 and 1 to identify a bitmap for each pixel, the pixel corresponding to 0 with the background color of a pixel corresponding to the Foreground. A lattice can be an array of characters to store, that store the character bitmap, in order to save space and can be used 16 of the array to store band. Display characters is the first digital map to determine the identity pixel is 0 or 1, then 1 pixel corresponds to it is displayed, and corresponds to the 0-pixel is not displayed.
