Convert HTML string to image
Thanks all for your responses. I used HtmlRenderer external dll (library) to achieve the same and found below code for the same.
Here is the code for this
public void ConvertHtmlToImage()
{
Bitmap m_Bitmap = new Bitmap(400, 600);
PointF point = new PointF(0, 0);
SizeF maxSize = new System.Drawing.SizeF(500, 500);
HtmlRenderer.HtmlRender.Render(Graphics.FromImage(m_Bitmap),
"<html><body><p>This is some html code</p>"
+ "<p>This is another html line</p></body>",
point, maxSize);
m_Bitmap.Save(@"C:\Test.png", ImageFormat.Png);
}
Try the following:
using System;
using System.Drawing;
using System.Threading;
using System.Windows.Forms;
class Program
{
static void Main(string[] args)
{
var source = @"
<!DOCTYPE html>
<html>
<body>
<p>An image from W3Schools:</p>
<img
src=""http://www.w3schools.com/images/w3schools_green.jpg""
alt=""W3Schools.com""
width=""104""
height=""142"">
</body>
</html>";
StartBrowser(source);
Console.ReadLine();
}
private static void StartBrowser(string source)
{
var th = new Thread(() =>
{
var webBrowser = new WebBrowser();
webBrowser.ScrollBarsEnabled = false;
webBrowser.DocumentCompleted +=
webBrowser_DocumentCompleted;
webBrowser.DocumentText = source;
Application.Run();
});
th.SetApartmentState(ApartmentState.STA);
th.Start();
}
static void
webBrowser_DocumentCompleted(
object sender,
WebBrowserDocumentCompletedEventArgs e)
{
var webBrowser = (WebBrowser)sender;
using (Bitmap bitmap =
new Bitmap(
webBrowser.Width,
webBrowser.Height))
{
webBrowser
.DrawToBitmap(
bitmap,
new System.Drawing
.Rectangle(0, 0, bitmap.Width, bitmap.Height));
bitmap.Save(@"filename.jpg",
System.Drawing.Imaging.ImageFormat.Jpeg);
}
}
}
Note: Credits should go to Hans Passant for his excellent answer on the question WebBrowser Control in a new thread which inspired this solution.
