大哥哥，大姐姐，点阵：怎么将输入的文字转换成指定大小的点阵

大哥哥，大姐姐，点阵：如何将输入的文字转换成指定大小的点阵？
如何将输入的文字转换成指定大小的点阵。比如输入一个字“中”，可以按照要求转换成8*8,16*16,24*24，32*32等规格的点阵图

就是说要的结果是类似16进制，如64*32的LED屏幕显示22222，那么得到的16进制是：
64 div 8 = 8
8 * 32 = 256
所以下面也是256个点（00算一个点的话）

那如果发送“我是龙卷风”，那么得到的16进制是：
也就是说每行最多只显示4个中文字，单字节每行可以显示8个，如数字或英文，所以超过4个中文字就从1，1这个坐标开始显示中文字，来进行点阵

有没有一个公式来计算呢，然后把输入的文字和屏幕长和宽套进去？

大致代码，注意方向可能不同

Delphi(Pascal) code

function str2bitmap (const s:string):string;
begin
    result:='';
    b:=0;
    imagehide.picture.bitmap.canvas.textout(0,0,str);
    for y:=0 to 16-1 do
        for x:=0 to 48-1 do
        begin
            if imagehide.picture.bitmap.canvas.pixel[x,y]=imagehide.picture.bitmap.canvas.font.color then
                b:=b or (1 shl (x mod 16));
            if (x mod 16=15) then
            begin
                result:=result+format(" %.2x",[b]);
                b:=0;
            end;
        end;
end;

------解决方案--------------------

跟踪一下，b:=b or (1 shl (x mod 16));执行到过没有

另外，
b:=b or (1 shl (x mod 16));
if (x mod 16=15) then
该改为
b:=b or (1 shl (x mod 8));
if (x mod 8=7) then
