Render Text

Hello!

I have a question about a plugin I am currently writing (in CodeLab).

Is there a way to render text to an image? Like: I want to write "50" at x 200px and y 300px.

I have a color bar (like in a FEM-Software) and want to lable it now from top to bottom

1.0

0.75

0.5

0.25

0.0

Thanks a lot!

Gilbert.

There is an example on this page: http://www.boltbait.com/pdn/codelab/hel ... ments.html

// Author: Ego Eram Reputo
#region UICode
FontFamily Amount1 = new FontFamily("Arial"); // Font
#endregion

void Render(Surface dst, Surface src, Rectangle rect)
{
  Rectangle selection = EnvironmentParameters.GetSelection(src.Bounds).GetBoundsInt(); 
  ColorBgra PC = (ColorBgra)EnvironmentParameters.PrimaryColor;
  // Reset the destination canvas
  for (int y = rect.Top; y    {
     for (int x = rect.Left; x       {
        dst[x,y] = src[x,y];
     }
  }
  // Create a brush and graphics surface to write on
  SolidBrush Brush1=new SolidBrush(
     Color.FromArgb(PC.A,PC.R,PC.G,PC.);
  Graphics g = new RenderArgs(dst).Graphics;
  g.SmoothingMode = 
     System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
  g.Clip = new Region(rect);
  // Create a font from user selection
  Font SelectedFont=new Font(Amount1.Name, 16);
  // Write our text to the canvas
  g.DrawString("Paint.NET Rocks!", SelectedFont, 
     Brush1, selection.Left, selection.Top);
}

If spacing is critical I'd recommend hard coding the font and size, but you'd need therefore to make the font a generic one so that you don't have to worry about it not being found on the users machine.

Google "web safe fonts" for a list :wink:

The location of the text is set by the last two variables in the g.DrawString call, selection.Top and selection.Left in the above example.
