Namespace:  Microsoft.VisualBasic.PowerPacks
Assembly:  Microsoft.VisualBasic.PowerPacks.Vs (in Microsoft.VisualBasic.PowerPacks.Vs.dll)

Syntax

'Declaration
Public MustOverride Sub DrawToBitmap ( _
    bitmap As Bitmap, _
    targetBounds As Rectangle _
)
'Usage
Dim instance As Shape 
Dim bitmap As Bitmap 
Dim targetBounds As Rectangle

instance.DrawToBitmap(bitmap, targetBounds)

public abstract void DrawToBitmap(
    Bitmap bitmap,
    Rectangle targetBounds
)

public:
virtual void DrawToBitmap(
    Bitmap^ bitmap, 
    Rectangle targetBounds
) abstract

public abstract function DrawToBitmap(
    bitmap : Bitmap, 
    targetBounds : Rectangle
)

Parameters

• bitmap
  Type: System.Drawing.Bitmap

• targetBounds
  Type: System.Drawing.Rectangle

  The Rectangle within which the LineShape is rendered.

Remarks

If the X or Y coordinates or the Width or Height parameters of targetBounds are less than 0, an ArgumentException will be thrown.

Examples

The following example demonstrates how to use the DrawToBitmap method to draw a LineShape on top of a PictureBox control.

Dim pic As New System.Drawing.Bitmap(Me.PictureBox1.Image, _
 PictureBox1.Width, PictureBox1.Height)
Dim rect As New System.Drawing.Rectangle(LineShape1.X1, _
    LineShape1.Y1, LineShape1.X2 - LineShape1.X1, _
    LineShape1.Y2 - LineShape1.Y1)
LineShape1.DrawToBitmap(pic, rect)
PictureBox2.Image = pic

System.Drawing.Bitmap pic = new System.Drawing.Bitmap(this.pictureBox1.Image, 
    pictureBox1.Width, pictureBox1.Height);
System.Drawing.Rectangle rect = new System.Drawing.Rectangle(lineShape1.X1, 
    lineShape1.Y1, lineShape1.X2 - lineShape1.X1, lineShape1.Y2 - lineShape1.Y1);
lineShape1.DrawToBitmap(pic, rect);
pictureBox2.Image = pic;
