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
"PrivateFontCol lection" 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(objec t sender, System.EventArg s e)
{
try
{
System.Drawing. Text.PrivateFon tCollection pfc = new
PrivateFontColl ection();
pfc.AddFontFile (Server.MapPath ("DarkGardenMK. ttf"));

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

Bitmap tmpBitmap = new Bitmap(400,100, PixelFormat.For mat32bppArgb);
Graphics objGraphics = Graphics.FromIm age(tmpBitmap);
objGraphics.Dra wString("Hello World!", dgFont, new
SolidBrush(Colo r.White ),0,0);

Response.Clear( );
Response.Conten tType = "image/jpeg";
tmpBitmap.Save( Response.Output Stream,ImageFor mat.Jpeg);

Response.End();
tmpBitmap.Dispo se();

}
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.Output Stream,ImageFor mat.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.serve r.com'>Home</a><br><hr>");
tmpBitmap.Save( Response.Output Stream,ImageFor mat.Jpeg);

Response.Write( "<hr><a href='www.serve r.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.Conten tType = "image/jpeg";
tmpBitmap.Save( Response.Output Stream,ImageFor mat.Jpeg);
Response.End();// end the current response and render to client
