Flash8 Bitmap buffer applications: Sticker

Personally think this method is much cheaper than using flashcom, is a bit of resources, but the requirements of the environment is very simple. We'll show you a formal application in two days.

This is my use of Flash8 bitmap buffer to make the bulk paste application.

Completely independent of flashcom, this big sticker is not like the previous, to Flashcommunicationserver to help.
This use of Flash8 bitmap buffer technology, do not need to Flashcommunicationserver server Java program writing really cost my boss's strength Ah!! Two days, but it's worth it, haha. Note: If you want to test, you must have a camera and flash Player 8 to do. (In fact, the camera is not necessary, no camera, you can not see the real effect, but the function can still be achieved, haha)

I'll put the JavaBean on, and the JSP file that I accepted.
Look at the JSP first.

<%@ page contenttype= "text/html; charset=gb2312 "language=" java "import=" com.n0rthwood.* "errorpage=" "%>"
<%
Prevent caching
Response.setheader ("Pragma", "No-cache");
Response.setheader ("Cache-control", "No-cache");
Counter
String click= (String) application.getattribute ("click");
%>
<%
Initializing counters
if (click==null| | Click.equals ("")) {
click= "1";
}
int Tmp=integer.parseint (click);
tmp=tmp+1;
Click= "" +TMP;
Application.setattribute ("click", click);
Receive Picture length width
String widthstr= (String) request.getparameter ("width");
String heightstr= (String) request.getparameter ("height");
if (widthstr==null| | heightstr==null| | Widthstr.equals ("") | | Heightstr.equals ("")) {
Turn to error page
Response.sendredirect ("erro.jsp");
Return
}
%>
<%
Converts a long width from a string to an integral type
int Widthint=integer.parseint (WIDTHSTR);
int Heightint=integer.parseint (HEIGHTSTR);
Receives picture pixels, because the image pixel is an array of behavior units, so you can loop the height so many times to receive all rows.
String[] Pixelcolor=new string[widthint-1];
for (int i=0;ipixelcolor[i]= (String) request.getparameter ("px" +i);
}
try{
Call my JavaBean to write the picture to the hard drive
Com.n0rthwood.JpgTest.JpgTset (Widthint,heightint,pixelcolor);
Turn to the picture that just generated
Response.sendredirect ("temp.jpg");
}catch (Exception e) {
If an error occurs, an error message is displayed
Out.println (E.tostring ());
}
%>
And then the JavaBean.
