不用图像组件的ASP图像计数器_asp

asp 搞代码 3年前 (2018-08-10) 80次浏览 已收录 0个评论

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

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
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!
