用ASP生成XBM数字图片（可用来生成验证码）直线网www.linecg.comXBM图片是一个纯文本的文件，可以用ASP来自动生成。可以用它来使用网站登陆的验证码；我们用记事本打开该文件进行分析：其文件结构为：[color=Blue]#definecounter_width48#definecounter_height9staticunsignedcharcounter_bits[]={7c,3c,7c,3c,70,3c,fe,7c,fe,7c,78,7c,ee,ee,ee,ee,7c,ee,e0,ee,60,ee,74,ee,70,fe,30,fe,70,fe,38,ec,e0,ec,70,ec,1c,e0,ee,e0,70,e0,fe,7e,fe,7e,70,7e,fe,3c,7c,3c,70,3c}[/color]文件扩展名为：.xbm[color=Blue]#definecounter_width48[color=Red]''这儿定义的是图片的宽度，一般为8的倍数[/color]#definecounter_height9[color=Red]''这儿定义的是图片的高度，是任意的。[/color]staticunsignedcharcounter_bits[]={7c,3c,7c,3c,70,3c,fe,7c,fe,7c,78,7c,ee,ee,ee,ee,7c,ee,e0,ee,60,ee,74,ee,70,fe,30,fe,70,fe,38,ec,e0,ec,70,ec,1c,e0,ee,e0,70,e0,fe,7e,fe,7e,70,7e,fe,3c,7c,3c,70,3c}[color=Red]''这儿是图片用来显示内容的十六进制的代码[/color][/color]正如staticunsignedchar英文意思为静态的，无符号的，烧焦的。它只能用来显示黑白两种颜色。二进制中的1将来用显示为黑色，0为白色。下面为0~9数字的二进制数组（其中的图片样式仅试用于本例。如果需要别的0~9数字样式，请另自行生成）[color=Blue]''此处声明0~9绘图用数组[/color][color=Red]dimnum(9,8''数字0num(0,0="0x38"num(0,1="0x7c"num(0,2="0xee"num(0,3="0xee"num(0,4="0xee"
