AutoSize Method

Summary

Adjusts this AnnTextObject object to where its bounds closely fit its contents.

Syntax

C++

public virtual void AutoSize()

  
Public Overridable Sub AutoSize()

public: 
virtual void AutoSize();

Remarks

Call this method to change the bounds (AnnTextObject.Bounds) value to closely fit its contents. The control will automatically add the correct space around the text for the current font style and size leading and takes into consideration the border size.

When using automation, setting the value of the AnnTextEditDesigner.AutoSizeAfterEdit property to true will result in the toolkit calling the AnnTextObject.AutoSize to adjust the object.

Example

using Leadtools; 
using Leadtools.Annotations; 
using Leadtools.Codecs; 
using Leadtools.WinForms; 
 
public void AnnTextObject_AutoSize(AnnContainer container, RasterImageViewer viewer) 
{ 
   // first add a new text object 
   AnnTextObject text = new AnnTextObject(); 
   text.Pen = new AnnPen(Color.Red, new AnnLength(3)); 
   text.Text = "Hello World!"; 
   text.Brush = null; 
   text.Font = new AnnFont("Arial", new AnnLength(10, AnnUnit.Point), FontStyle.Regular); 
   text.EdgeMargin = AnnLength.Empty; 
   text.Alignment = StringAlignment.Center; 
   text.LineAlignment = StringAlignment.Center; 
   text.TextRotate = AnnTextRotate.Rotate0; 
   text.Bounds = new AnnRectangle(100, 100, 400, 600, AnnUnit.Pixel); 
   container.Objects.Add(text); 
   viewer.Invalidate(); 
 
   MessageBox.Show("A text object with the original bounding rectangle"); 
 
   // now make the object firts the content (its text) 
   text.AutoSize(); 
   viewer.Invalidate(); 
 
   MessageBox.Show("Same text object after AutoSize"); 
}
