RasterImageGdiPlusGraphicsContainer Constructor

Summary
Creates a new instance of the RasterImageGdiPlusGraphicsContainer class from a Leadtools.RasterImage.
Syntax
C#
C++/CLI
Python
public: 
RasterImageGdiPlusGraphicsContainer(  
   RasterImage^ image 
) 
__init__(self,image) # Overloaded constructor 

Parameters

image
The source Leadtools.RasterImage.

Remarks

Use RasterImageConverter.TestCompatible to determine if the image is compatible for creating a GDI+ Graphics object.

This allows you to create an infinite number of drawing capabilities such as paint, erase, color erase and brush, pen, spray gun, flood fill, color tube, text overlay, curve, line, rectangle, polygon, ellipse, freehand shapes, cut and paste, and more to use on the surface of this Leadtools.RasterImage.

For more information refer to RasterImage and GDI/GDI+.

Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Drawing; 
 
 
public void RasterImageGdiPlusGraphicsContainerExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp"); 
   string destFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1_CreateGdiPlusGraphics.bmp"); 
 
   // Load the image 
   using (RasterImage image = codecs.Load(srcFileName)) 
   { 
      // Create a graphics object for this image surface and draw something on it 
      using (RasterImageGdiPlusGraphicsContainer container = new RasterImageGdiPlusGraphicsContainer(image)) 
      { 
         using (Graphics g = container.Graphics) 
         { 
            using (Brush b = new SolidBrush(Color.FromArgb(128, 0, 0, 0))) 
            { 
               g.FillEllipse(b, new Rectangle(0, 0, image.ImageWidth, image.ImageHeight)); 
            } 
         } 
      } 
 
      // Save the image back on disk 
      codecs.Save(image, destFileName, RasterImageFormat.Bmp, 24); 
   } 
 
   codecs.Dispose(); 
}
