My Code:
<asp:Image ID="myImage" ImageUrl="~/GetImage.ashx?id=Chiken" runat="server" />
Code Behind:
public Image DrawText(String text, Font font, Color textColor, Color backColor)
{
//first, create a dummy bitmap just to get a graphics object
Image img = new Bitmap(1, 1);
Graphics drawing = Graphics.FromImage(img);
//measure the string to see how big the image needs to be
SizeF textSize = drawing.MeasureString(text, font);
//free up the dummy image and old graphics object
img.Dispose();
drawing.Dispose();
//create a new image of the right size
img = new Bitmap((int)textSize.Width, 80);
drawing = Graphics.FromImage(img);
//paint the background
drawing.Clear(backColor);
//create a brush for the text
Brush textBrush = new SolidBrush(textColor);
drawing.DrawString(text, font, textBrush, 0, 0);
drawing.Save();
textBrush.Dispose();
drawing.Dispose();
return img;
}
And Call Back in ashx file
public void ProcessRequest(HttpContext context)
{
Font font = new Font("Revalo Modern Regular", 44, FontStyle.Bold);
Color color = Color.FromArgb(242, 139, 0);
Color background = Color.FromArgb(255, 255, 255);
Image img = DrawText(HttpContext.Current.Request.QueryString["id"].ToString(), font, color, background);
img.Save(context.Response.OutputStream, ImageFormat.Jpeg);
}
Tried:
img.SaveAs(Server.MapPath("../Images/"+context.Response.OutputStream.ToString()))
I', tried How to generate an image from text on fly at runtime
