MapServer安裝之后并不具有WMS服務(wù)功能 所有的配置圍繞著Mapfile進(jìn)行 【http://mapserver.gis.umn.edu/docs/howto/wms_server】 1.判別當(dāng)前MapServer是否支持WMS #>mapserv.exe -v
MapServer version 4.6.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=PDF
OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER
SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER
INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE DEBUG=MSDEBUG 看到以上內(nèi)容就ok了 2.修改mapfile 對(duì)于mapserver 5.0 的樣例數(shù)據(jù) workshop-50.zip 添加:
PROJECTION
"init=epsg:4269"
END
"wms_onlineresource" "http://192.168.14.65:8080/cgi-bin/mymap.exe?"
httpd.conf 添加
SetEnvIf Request_URI "/cgi-bin/mymap.exe" MS_MAPFILE=c:/gis/ms4w/Apache/htdocs/workshop-50/itasca.map
路徑不能加""哦
復(fù)制mapserve.exe 為mymap.exe
3.重新啟動(dòng) httpd.exe
4.測(cè)試：
jump或者qgis測(cè)試，添加wms層 ，browser添加 http://192.168.14.65:8080/cgi-bin/mymap.exe?
選擇一些layer就可以查看嘍
Mapserver的安裝介質(zhì)可從 http://mapserver.gis.umn.edu下載
安裝也非常簡(jiǎn)單，選擇何時(shí)的服務(wù)http端口就可以了，這里我選擇了8080
下載ms4w 5.0的App數(shù)據(jù) workshop-5.0.zip
將其簡(jiǎn)單解壓縮到 $apache/htdocs下即可；創(chuàng)建$(apache)/tmp目錄
修改worksop-5.0/index.html文件，將其中 IMAGEPATH,IMAGEURL 修改為workship-5.0的路徑即可
// EDIT THE NEXT 2 LINES TO MATCH YOUR SETUP
var snippet = "IMAGEPATH 'C:/gis/ms4w/Apache/htdocs/tmp/'";
snippet += " IMAGEURL '/tmp/'";
<!-- EDIT THESE HIDDEN VARIABLES -->
<input type="hidden" name="map" value="C:\gis\ms4w\Apache\htdocs\workshop-5.0\itasca.map">
<input type="hidden" name="program" value="/cgi-bin/mapserv.exe">
<input type="hidden" name="root" value="/workshop-5.0">
來(lái)測(cè)試一下 http://127.0.0.1/workshop-5.0,即可看到itasca.map了
好好研究一把mapserver,配置好wms/wfs server 看看用openlayers/Qgis的效果
如題，今天google是愁到這個(gè)問(wèn)題
flash確實(shí)現(xiàn)在無(wú)處不在，所以不存在是否要求client browser安裝已否，已經(jīng)成了標(biāo)配。
目前沒(méi)有仔細(xì)研讀過(guò)openlayers的實(shí)現(xiàn)代碼，所以?xún)烧叩慕Y(jié)合會(huì)有哪些問(wèn)題目前尚不能給出區(qū)分，不過(guò)openlayers圖層的編輯Marker，確實(shí)是個(gè)頭疼的問(wèn)題，javascript再?gòu)?qiáng)，實(shí)現(xiàn)的難度還是人盡共知的，所以flash確實(shí)個(gè)是補(bǔ)充的好方法
花時(shí)間研究吧
reference: http://netpbm.sourceforge.net/doc/ppm.html
Each PPM image consists of the following:
- A "magic number" for identifying the file type.
A ppm image's magic number is the two characters "P6".
-
Whitespace (blanks, TABs, CRs, LFs).
-
A width, formatted as ASCII characters in decimal.
-
Whitespace.
-
A height, again in ASCII decimal.
-
Whitespace.
-
The maximum color value (Maxval), again in ASCII decimal. Must be less
than 65536 and more than zero.
- A single whitespace character (usually a newline).
- A raster of Height rows, in order from top to bottom. Each row
consists of Width pixels, in order from left to right. Each pixel is
a triplet of red, green, and blue samples, in that order. Each sample
is represented in pure binary by either 1 or 2 bytes. If the Maxval
is less than 256, it is 1 byte. Otherwise, it is 2 bytes. The most
significant byte is first.
A row of an image is horizontal. A column is vertical. The pixels
in the image are square and contiguous.
- In the raster, the sample values are "nonlinear." They are
proportional to the intensity of the ITU-R Recommendation BT.709 red,
green, and blue in the pixel, adjusted by the BT.709 gamma transfer
function. (That transfer function specifies a gamma number of 2.2 and
has a linear section for small intensities). A value of Maxval for
all three samples represents CIE D65 white and the most intense color
in the color universe of which the image is part (the color universe
is all the colors in all images to which this image might be
compared).
ITU-R Recommendation BT.709 is a renaming of the former CCIR
Recommendation 709. When CCIR was absorbed into its parent
organization, the ITU, ca. 2000, the standard was renamed. This
document once referred to the standard as CIE Rec. 709, but it isn't
clear now that CIE ever sponsored such a standard.
Note that another popular color space is the newer sRGB. A common
variation on PPM is to subsitute this color space for the one specified.
-
Note that a common variation on the PPM format is to have the sample
values be "linear," i.e. as specified above except without
the gamma adjustment. pnmgamma takes such a PPM variant as
input and produces a true PPM as output.
- Strings starting with "#" may be comments, the same as
with PBM.
string Char2Hex(char a)
{
string str = "";
int n = a;
for (int i=2*sizeof(char) - 1; i>=0; i--)
{
str += "0123456789ABCDEF"[((n >> i*4) & 0xF)];
}
return str;
}

為了找些crack的工具，沒(méi)辦法下載了很多crackxxx的東西，后悔沒(méi)有在虛擬機(jī)里面試驗(yàn)一下，直接在我的開(kāi)發(fā)機(jī)上運(yùn)行，導(dǎo)致木馬，病毒滿天飛。

煩都煩死了，也沒(méi)找到他在registy的位置，干不掉，看著也煩，只能寫(xiě)個(gè)程序，定時(shí)檢測(cè)是否其窗體開(kāi)啟，并關(guān)閉它

table 是個(gè)怪物，有很多facets,類(lèi)似array,map,struct,整個(gè)是個(gè)混合物，用起來(lái)也比較怪異。
t={1,2,3,a="gen",b=100}
t={[0]=1;["name"]="ultra"}
t.a, t.b , t[0] , t["name"]
表操作函數(shù):
ipairs,pairs迭代函數(shù)
table.getn(t) len of table
================================================================
function() 可以接受任意多的參數(shù)，如果實(shí)參數(shù)過(guò)多將丟棄，過(guò)少將默認(rèn)設(shè)置為nil
同樣可以返回多個(gè)參數(shù)
a,b=foo()
表作為參數(shù)傳遞到function
function rename( arg ) os.rename(arg.old,arg.new) end
rename{old="";new=""}
匿名函數(shù)(lambda in python )
foo = function(x) return x*2 end
局部函數(shù) local f=function(x) ... end
================================================================
for n=start,end,step do ... end
while b do ... end
repeat do .... until
if then .. elseif then ... end;
有意思的語(yǔ)法表達(dá)式:
print a or b or c 如果a=false,嘗試b...
注釋: -- --{ --}
字符串操作: .. 連接
==================================================
io 函數(shù):
loadfile('test.lua')() execute external lua script
loadstring('print 100')()
代碼測(cè)試:
=======================
c程序調(diào)用lua函數(shù)
c 程序:
void call_lua_func(){
lua_State *s = lua_open();
luaL_openlibs(s);
int c = lua_gettop(s);
luaL_dofile(s,"/nandflashpartition/test1.lua");
lua_getglobal(s,"add");
lua_pushnumber(s,0.25);
lua_pushnumber(s,8);
if( lua_pcall(s,2,1,0)){
std::cout<< lua_tostring(s,-1)<<std::endl;
}
double r;
r = lua_tonumber(s,-1);
lua_close(s);
}
lua程序:
function add(x,y)
return x*y
end

lua訪問(wèn)c程序空間變量
1.定義變量student.h
extern char * gender;
extern int class_count;
2.創(chuàng)建pkg文件 student.pkg
$#include "student.h"
extern char * gender;
extern int class_count;
3.產(chǎn)生tolua++存根框架
tolua++ -o student.pkg
4.創(chuàng)建lua測(cè)試代碼 call_c.lua
print(gender)
print(class_count) 訪問(wèn)c 空間的變量
5.c測(cè)試代碼
char * gender;
int class_count;
void lua_call_c(){
int tolua_student_open (lua_State* tolua_S);
lua_State * s = lua_open();
luaopen_base(s);
gender ="my gender is male!";
class_count = 100;
tolua_student_open(s);
luaL_dofile(s,"/nandflashpartition/call_c.lua");
lua_close(s);
}
6.build && test it!
