Hi,

When you use DrawString, say for Arial Black White on a RGB background. The quality of the color and the text is awful.  Does anyone know how I can get a crisp clean finish to the text and the background color?

thanks in advance

By awful, do you mean jagged (aliased) ?

If so, then you could try apply the following to your Graphics instance prior to drawing the string:

   myGraphicsInstance.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;

In order to antialias the graphics.

Hopefully that will work for fonts as well.
If not however, then perhaps draw the text to your own Graphics instance, and run your own antialiasing algorithm to smooth it.

when I say awful I mean like if I put a white font on a blue background I get tons of multicolored fine noise around the text and it looks like really low quality Gif. what would cause this?

Certainly, thank you for your time

protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.QueryString["sid"] != null)
        {
            Response.Clear();
            Response.ContentType = "image/jpeg";
            System.Drawing.Image NewOne = GenerateImage(Convert.ToInt32(Request.QueryString["sid"]));
            NewOne.Save(Response.OutputStream, ImageFormat.Jpeg);
        }
    }
    private System.Drawing.Image GenerateImage(int SID)
    {
        string StrSql = "SELECT story_title FROM story_view WHERE story_id =" + SID;
        SqlDataAdapter StoryAdp = new SqlDataAdapter(StrSql, MConn);
        DataSet StoryDs = new DataSet();
        StoryAdp.Fill(StoryDs);
        DataRow NewRow = StoryDs.Tables[0].Rows[0];
        string Title = NewRow[0].ToString();
        Bitmap b = new Bitmap(Server.MapPath("../layout_images/bar.jpg"));
        Graphics g = Graphics.FromImage(b);
        SizeF TextWidth = g.MeasureString(Title, new Font("Arial Black", 14));
        //g.Clear(Color.FromArgb(116, 147, 235));
        SolidBrush Solid3 = new SolidBrush(Color.White);
        g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAliasGridFit;
        g.DrawString(Title, new Font("Arial Black", 14, FontStyle.Regular), Solid3, new Rectangle(0, 5, 444, 35));
        g.Dispose();
        return b;
    }

Do you get the noise if you write the response as a format other than JPEG?
Such as image/gif.
