Properly Sizing a Bitmap

[smgrisw]

All,

I am trying to create a bitmap dynamically based on a selection of text. Code is below:

bitMapImage = new
                System.Drawing.Bitmap(90,50);
 
      Graphics graphicImage = Graphics.FromImage(bitMapImage);
 
            graphicImage.Clear(Color.White);
            SolidBrush drawBrush = new SolidBrush(Color.Red);
 
            graphicImage.DrawString(comboStampText.Text +  DateTime.Now.ToShortDateString(),
               new Font("Arial", 18, FontStyle.Regular),
               drawBrush, new Point(5, 5));
 

Everthing works except I am having difficulty sizing the bitmap correctly based on the length of the text. Is there a way that this can be accomplished?

Regards,

Scott

You can use System.Graphics.MeasureString(text, font) to get the size of your string for that graphics instance - but it also has a couple of things you should know before using it, check this link for an example: http://www.codeproject.com/KB/GDI-pl...urestring.aspx

There is also the System.Windows.Forms.TextRenderer class, which behaves a bit different when rendering (it uses plain GDI instead of GDI+). In some cases it is a better solution (for example, when rendering semi-transparent text to a bitmap, it does a better job with anti-aliasing).
