copied!<p>I'm using following C# code to make a picture with a text in it</p> <pre><code> // Create font. Parameter is a global variable Font objFont = new Font(fontname, fontsize, fontstyle, System.Drawing.GraphicsUnit.Pixel); // Grab an existing image from picture box. (target is picturebox's name) Bitmap result; if (target.Image != null) { result = new Bitmap(target.Image); } else { result = new Bitmap(target.Width, target.Height); } Graphics objGraphics = Graphics.FromImage(result); // And draw to it. Select a mode with check box. objGraphics.SmoothingMode = SmoothingMode.HighQuality; if (!checkBox1.Checked) { objGraphics.TextRenderingHint = TextRenderingHint.AntiAliasGridFit; } else { objGraphics.TextRenderingHint = TextRenderingHint.ClearTypeGridFit; } Brush b = new LinearGradientBrush(new Rectangle(new Point(x, y), objGraphics.MeasureString(text, objFont).ToSize()),color1,color2,LinearGradientMode.Vertical); objGraphics.DrawString(text, objFont, b, x, y); objGraphics.Save(); //Set the result to picturebox target.Image = result; objGraphics.Dispose(); b.Dispose(); </code></pre> <p>prior to this code, target.BackColor has been set into a desired color like </p> <pre><code>target.BackColor = Color.Black; </code></pre> <p>This is the results :</p> <p><a href="http://image.free.in.th/z/ie/yqbsg.png" rel="nofollow noreferrer">http://image.free.in.th/z/ie/yqbsg.png</a></p> <p>I was wondering that why ClearType font looks so ugly on bright bg? (On bg like dark purple you won't notice black border but it's still there)</p>
