Draw rotated text with GDI+

[JumpyNET]

I'm using the following code to draw a rotated string inside a circle to a picture box. Any ideas how I could make the picture quality better for the text? I was thinking something like making it first bigger and then smaller - but don't know how to accomplish this. I'm also having problems positioning the text inside the circle. Note that the text width can change.

 

       'This function will draw a circle with rotated text inside it.

       'This should be the centerpoint of the text and circle
       Dim CenterPoint As System.Drawing.Point = New System.Drawing.Point(20, 60)

       'Declarations
       Dim GraphicObject As Graphics
       Dim BitmapObject As Bitmap
       BitmapObject = New Bitmap(PictureBox1.Width, PictureBox1.Height, PictureBox1.CreateGraphics)
       GraphicObject = Graphics.FromImage(BitmapObject)

       'Let's draw a circle
       GraphicObject.DrawEllipse(New Pen(Color.Blue, 5), CenterPoint.X, CenterPoint.Y, 50, 50)

       'Let's draw rotated text inside the circle
       GraphicObject.TranslateTransform(CenterPoint.X, CenterPoint.Y)
       GraphicObject.RotateTransform(-45.0F)
       GraphicObject.DrawString("hh:mm:ss:ms", New Font("Arial", 8, FontStyle.Regular), Brushes.Red, 0.0F, 0.0F)
       GraphicObject.ResetTransform()

       'Let's update the picturebox
       PictureBox1.Image = BitmapObject
       GraphicObject.Dispose()

Set the Hinting (might be TextHinting or something like that) property of the graphics object. There should be an option for anti-aliasing, an option for clear-type, and an option for aliased. That should help with the quality.

Thank you! I found the setting:

GraphicObject.TextRenderingHint = Drawing.Text.TextRenderingHint.AntiAlias

Never thought it could be that easy.

 

 

PS: I'm still strugling with that the text centering.
