Render Image from Font

[localhost]

I have a custom TrueType .ttf font in the filesystem (not installed)
on the web server.

I want to take the letter "A" from this font, render it as an image,
and return that as a byte stream in a web page.

How can I do that?


Thanks.

See System.Drawing. You can do a "usual" Windows graphics app and then
stream the bitmap to the browser...

Why not just create image files (.png, .jpg, .gif) of each letter.
Then just reference your letter with an <IMG> tag.

<IMG src='letterCapA.png'> Good Example

Hi Localhost,

As for your question, I think the GDI+ components under the System.Drawing
/System.Drawing.Text namespace can finish the task. Also, w can use the
"PrivateFontCollection" class to load a (true type font) ttf file from disk
into memory and create a tempory font instance so as to use it(without
installed in the system's font library), here is a simple code snippet.
Hope helps:


=====================================
private void Page_Load(object sender, System.EventArgs e)
{
try
{
System.Drawing.Text.PrivateFontCollection pfc = new
PrivateFontCollection();
pfc.AddFontFile(Server.MapPath("DarkGardenMK.ttf"));

FontFamily family=new FontFamily("Dark Garden",pfc);
Font dgFont=new Font(family,40);

Bitmap tmpBitmap = new Bitmap(400,100,PixelFormat.Format32bppArgb);
Graphics objGraphics = Graphics.FromImage(tmpBitmap);


objGraphics.DrawString("Hello World!", dgFont, new
SolidBrush(Color.White ),0,0);

Response.Clear();
Response.ContentType = "image/jpeg";
tmpBitmap.Save(Response.OutputStream,ImageFormat.Jpeg);

Response.End();
tmpBitmap.Dispose();

}
catch(Exception ex)
{
Response.Write("<br>" + ex.Message);
}

}

============================================

In addtion, below is the codeproject article I refer to , that has the more
detailed explanition.

I'm just curious with this code.

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

This line makes the browser display a image only or can you include HTML
Tags as well, as in the following code:

Response.Write("<a href='www.server.com'>Home</a><br><hr>");
tmpBitmap.Save(Response.OutputStream,ImageFormat.Jpeg);

Response.Write("<hr><a href='www.server.com'>Home</a>");

Hi Gabe,

Of course not, one response stream can only be specified one content-type.
IF we return image stream, we must clear other content. That's why I use

Response.Clear();//clear other content
Response.ContentType = "image/jpeg";
tmpBitmap.Save(Response.OutputStream,ImageFormat.Jpeg);
Response.End();// end the current response and render to client
