Generate image on the fly c#

[Popoxinhxan]

HI guy

I am working on the web application that required to display

the chart image on the page. The process is clicking the button

and browser will popup another windows that displayed the

image. The problem is the image is not a file but a array of

bytes so that i couldn't using it's image url to display in

different browser. Is there any way to create an image on the

fly i.e. get the array of bytes and display it on the browser

Assume i have an Generate.aspx that contain the button and its

input to generate the image ie.image width, image height, an Display.aspx to
show the image

and the following method

//Returns array of bytes

private byte[] GetBinaryImage( int width,int height)

{

//Get data from database

}

This is urgent someone help me to do so please.
Thank you

You can create another aspx, say, GimmeDaImage.as px, which would actually
output the image bytes and return the correct MIME type in the HTTP headers.

See docs on Response.Conten tType and Response.Binary Write.

And your image tag would look like

<IMG SRC="GimmeDaIma ge.aspx?ImageID =1">

Heres the steps i do it in

create an aspx page that calls your image draw routing in its page load
event

write a function that draws your image onto a bitmap

use bitmap.save to output your image to a stream. Use
Response.Output Stream as this stream.

for example
private void Page_Load(objec t sender, System.EventArg s e)
{
//initialise etc first

Renderer.Render ToStream(Respon se.OutputStream );
}

in my renderer class

Public void RenderToStream( Stream target)
{
//---
//do all your drawing
//---

//then to send back a jpg

EncoderParamete rs encoderParams = new EncoderParamete rs();
long[] quality = new long[1];
quality[0] = 99;

EncoderParamete r encoderParam = new EncoderParamete r(Encoder.Quali ty,
quality);
encoderParams.P aram[0] = encoderParam;
ImageCodecInfo[] arrayICI = ImageCodecInfo. GetImageEncoder s();
ImageCodecInfo jpegICI = null;

for (int x = 0; x < arrayICI.Length ; x++)
{
if (arrayICI[x].FormatDescript ion.Equals("JPE G"))
{
jpegICI = arrayICI[x];
break;
}
}

if (jpegICI != null)
{
bm.Save(target, jpegICI, encoderParams);
}

//clean up everything here

}
call this from another page (programaticall y) like

picDial.ImageUr l=@"dial.aspx?I D=1&VALUE="+sVa lue+"&TYPE="+sT ype+"&TITLE="+s Title;


http://darkhold.aspxconnection.com/Default.aspx

for the end result of what ive done.
