LockPicture Property

Summary

Gets or sets the AnnPicture used when drawing the locked symbol for locked objects.

Syntax

C++

public virtual Leadtools.Annotations.AnnPicture LockPicture {get; set;}

  
Public Overridable Property LockPicture As Leadtools.Annotations.AnnPicture

public: 
virtual property Leadtools.Annotations.AnnPicture^ LockPicture { 
   Leadtools.Annotations.AnnPicture^ get(); 
   void set (    Leadtools.Annotations.AnnPicture^ ); 
}

Property Value

The AnnPicture used when drawing the locked symbol for locked objects.

Remarks

All objects inside the container will use this picture when drawing the object if the object is locked.

The container uses a picture of a "lock" that is created by default. You can change this default picture by using this property.

This property can be set to AnnPicture.Empty to remove the lock picture.

Example

using Leadtools; 
using Leadtools.Annotations; 
using Leadtools.Codecs; 
using Leadtools.WinForms; 
 
public void AnnContainer_LockPicture(AnnContainer container) 
{ 
   // we are going to create a new lock image that is 20 by 20 red ellipse with a blue cross inside it. 
   Bitmap btmp = new Bitmap(20, 20, PixelFormat.Format32bppArgb); 
   using (Graphics graphics = Graphics.FromImage(btmp)) 
   { 
      // fill the image with a white color 
      graphics.FillRectangle(Brushes.White, new Rectangle(0, 0, 20, 20)); 
      graphics.FillEllipse(Brushes.Red, new Rectangle(0, 0, 20, 20)); 
      graphics.DrawLine(Pens.Blue, 0, 0, 20, 20); 
      graphics.DrawLine(Pens.Blue, 20, 0, 0, 20); 
   } 
 
   // create an annotation picture for this image, use white as the transparent color 
   AnnPicture pic = new AnnPicture(btmp); 
   pic.TransparentMode = AnnPictureTransparentMode.UseColor; 
   pic.TransparentColor = Color.White; 
 
   // use this picture to draw all locked objects in this container 
   container.LockPicture = pic;
