不用图像组件的ASP图像计数器 时间：2004/11/7 2:56:00来源：本站整理作者：蓝点我要评论(0): 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

Dim a(10,10)

a(0,1) = "0x3c" '数字0

a(0,2) = "0x66"

a(0,3) = "0xc3"

a(0,4) = "0xc3"

a(0,5) = "0xc3"

a(0,6) = "0xc3"

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

<%

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

digital = ""

For I = 1 To Length -Len( num ) '补0

digital = digital & "0"

Next

For I = 1 To Len( num )

digital = digital & Mid( num, I, 1 )

Next

For I = 1 To Len( digital )

sort(I) = Mid( digital, I, 1 )

Next

Width = 8 * Len( digital ) '图像的宽度

Height = 10 '图像的高度，在本例中为固定值

Response.ContentType="image/x-xbitmap"

hc=chr(13) & chr(10)

Image = "#define counter_width " & Width & hc

Image = Image & "#define counter_height " & Height & hc

Image = Image & "static unsigned char counter_bits[]={" & hc

For I = 1 To Height

For J = 1 To Length

Image = Image & a(sort(J),I) & ","

Next

Next

Image = Left( Image, Len( Image ) - 1 ) '去掉最后一个逗号

Image = Image & "};" & hc

Response.Write Image

%>

好了,简单的思路就是这样了,有什么错误的地方,还希望大家多多指正!
