不用图像组件的ASP图像计数器

来源:网络 责任编辑:栏目编辑 发表时间:2013-07-01 13:12 点击:
前几天看了netnice和qzsage君的贴子,颇有启发,于是着手编了一个图像计数器,这个图像计数器没有用图像组件,也不是以前那样用几张图片拼起来,而是用了*.xbm的图片格式。这种格式可能只能在Windows+IE下才能显示。
具体的思路是这样:
图片用点阵的形式表示,比如2:

00111100 0011为3 1100为C 即0x3c
01100110 0110为6 0110为6 0x66
01100000 ....... 0x表示十六进制数。
01100000 依此类推
00110000 这是用二进制数得到的点阵,其中的1为显示一黑点,0不显示
00011000 是一个反着看的2
00001100 其余数字可自已排列点阵再二进制化为十六进制数
00000110 缺点是只有黑白两种颜色
00000110 显示出来是白底黑字,要显示黑底白字的话,对其取反就行了
01111110

下面是我"画"的0-9的数字

num.asp

a(3,9) = "0x66"
a(3,10)= "0x38"

a(4,1) = "0x38" 数字4
a(4,2) = "0x3c"
a(4,3) = "0x36"
a(4,4) = "0x33"
a(4,5) = "0x33"

a(4,7) = "0xff"
a(4,8) = "0x30"

a(5,2) = "0xfe"
a(5,3) = "0x06"
a(5,4) = "0x06"
a(5,5) = "0x3e"
a(5,6) = "0x60"
a(5,7) = "0xc0"
a(5,8) = "0xc3"
a(5,9) = "0x66"
a(5,10)= "0x3c"

a(6,1) = "0x60" 数字6
a(6,2) = "0x30"
a(6,3) = "0x18"
a(6,4) = "0x0c"
a(6,5) = "0x3e"
a(6,6) = "0x63"
a(6,7) = "0xc3"
a(6,8) = "0xc3"
a(6,9) = "0x66"
a(6,10) ="0x3c"

a(7,1) = "0xff" 数字7
a(7,2) = "0xc0"
a(7,3) = "0x60"
a(7,4) = "0x30"
a(7,5) = "0x18"
a(7,6) = "0x18"
a(7,7) = "0x18"
a(7,8) = "0x18"
a(7,9) = "0x18"
a(7,10)= "0x18"

a(8,1) = "0x3c" 数字8
a(8,2) = "0x66"
a(8,3) = "0xc3"
a(8,4) = "0x66"
a(8,5) = "0x3c"
a(8,6) = "0x66"
a(8,7) = "0xc3"
a(8,8) = "0xc3"
a(8,9) = "0x66"
a(8,10)= "0x3c"

a(9,1) = "0x3c" 数字9
a(9,2) = "0x66"
a(9,3) = "0xc3"
a(9,4) = "0xc3"
a(9,5) = "0x66"
a(9,6) = "0x3c"
a(9,7) = "0x18"
a(9,8) = "0x0c"
a(9,9) = "0x06"
a(9,10)= "0x03"

%>

显示的方法是:

1.先传出一个MIME:
Response.ContentType = "image/x-xbitmap"
2.再传出一个c++的源程序,如显示2:
#define counter_width 8
#define counter_height 10
static unsigned char counter_bits[] = {
0x3c,0x66,0x60,0x60,0x30,0x18,0x0c,0x06,0x06,0x7e
};
这样在浏览器上就显示出来一个8*10像素的2了

要显示两个或以上的数字的时候,须改动宽度的值(必须是图像点阵宽度的整数倍),在count_bits[]数组的值排序如下:
比如显示 12
a(1,1), a(2,1), a(1,2), a(2,2)... a(1,10), a(2,10)
下面是具体计数器的例子:

count.asp

<!--#include file="num.asp"-->
<%
Dim Image
Dim Width, Height
Dim num
Dim digtal
Dim Length
Dim sort
Length = 10 自定计数器长度

Redim sort( Length )


num = 62275 计数器的值
