everything is to being done in code behind.

also please pass me some links where i can get good simple example of image handling in asp.net.

Thankyou all

Any help please?

In order to add this generated image, then in pages where you want to include the image you do this

<img src="process.aspx" /> you can also add a query string to it to identify a certain image like process.aspx?imageid=10

As to writing on the image itself use this code to modify the Image object you have in memory before you stream it back as a response.

// add watermark
Graphics graphics = Graphics.FromImage(bmp);
Font font = new Font("Courier New", 11);
SizeF size = graphics.MeasureString("© Copyright ", font);
Rectangle rect = new Rectangle(0, 0, (int)Math.Ceiling(size.Width) + 1, (int)Math.Ceiling(size.Height));
graphics.FillRectangle(new SolidBrush(Color.Wheat), rect);
graphics.DrawString("© Copyright ", font, new SolidBrush(Color.Black), rect);
graphics.Dispose();
// add watermark

Hello,

This is my process.aspx.cs part of code on page load event

       Bitmap bitMapImage = new

        System.Drawing.Bitmap(Server.MapPath("Image/image002.jpg"));

       Graphics graphicImage = Graphics.FromImage(bitMapImage);

       graphicImage.SmoothingMode = SmoothingMode.AntiAlias;

       graphicImage.DrawString(Request.QueryString["message"],

       new Font("Arial", 12, FontStyle.Bold),

       Brushes.Red, new Point(15, 125));

       Response.ContentType = "image/jpeg";

       //Save the new image to the response output stream.

       bitMapImage.Save(Response.OutputStream, ImageFormat.Jpeg);

       graphicImage.Dispose();

And in Process.aspx page I have added this line as you have said

<img src="process.aspx"/> 

I have image and text selected on main page that is passed thru querry string

from querry string i have to take image and text to display rendered image .

and I dont need to save this image on my hard disk.

this is what i am tring to do

but in process.aspx page Image is displayed without any trouble but other elements on that page are not displayed
 

You should not use the process.aspx page for anything other than to stream the image data.

You should not have any elements in it, in fact you should open the aspx page and remove all html elements, just leave the first line for the page directive.

Whatever you want to show as elements, you have to create another page and in that page, when you want to show the dynamic image you add

<img src="process.aspx?message=urtexthere" />

Hope this is clear now. Let me know.

Sorry for this questions but i didnt get you how i am going to achieve this.

i have main.aspx page where image is selected and text is enteted.

then this page  redirect the output to process.aspx./ querry string and both parameters

here all my code comes /image displying

and now if i create Finalpage.aspx // as you have suggested

then how do i get to that page?

where my image is shown with <img> tag and other elements

You can not redirect the output to process.aspx. You should forget the page process.aspx as being a page. Process.aspx is only used in the image tags now <img src="process...

So you should not redirect your output to process.aspx you should redirect it to finalpage.aspx and inside the finalpage.aspx you should have the image tag as I described it.

If you are sending the query parameters to finalpage, then inside the page finalpage you should write that inside the image tag as well

For example

add to the final page a public string message;

inside your page_load of your finalpage

message = Request["message"]

DataBind();

And finally in your aspx file of finalpage

<img src="process.aspx?message=<%=message%>" />

Hope this is clearer now.

Thanks this thing has worked as charm when i use static image and text

Now i have to upgrade this with image and text passed by user

in my main page i have selected my options and redirected to final page thru querry string

 and in final page code behind  i have used this line as it is

        string messager = Request["message"];

DataBind();

textbox1.text=messager;

now text box has this message // final page.aspx

now in final page i have used same

image tag

<img src="process.aspx?newmessage<%=messager%>"/>

and it gives error

  The name 'messager' does not exist in the current context   

any help

 

HI can you send me/email me the files or the full project so that I can fix your code. It is easier :)

Thanks.

that's interesting.  I didn't know this could be done this way.  Why not add the text in photoshop or another image editing program?

 I have sent you one email

I wanted to send you email with attachment  but can't find any attachment link

if u can reply back to this to my email (just now sent you mail thru this site) i will attach my files with it.
