draw a shape

hello,

My application is a windows based application using c#.net 2008 and .net framework is 3.5 and also use leadtools version 16.In my application, i drag and drop an rasterimageviewer in the form.It is for display in the image.No w i want to draw a shape on the image like polygon,rounded rectangle and polybezier etc.

regards

If you mean that you want to draw shapes on the raster image, you need to create a graphic object from the image, and use this graphic object to draw the rectangle, line, etc. Please check the following code:
+----------+
System.Drawing.Graphics G = MyRasterImageCreateGdiPlusGraphics().Graphics;
G.DrawLine(...)
+----------+

But if you mean that you want to give the user the ability to draw these shapes on the image, you can use the LEADTOOLS Annotaion objects. For more information, please see the following page:

Please give me the full code

hello,

     I want to draw the shape as,

1)Rounded Rectangle.

2)Polygon

3)Polybezier

Do you want to draw the shapes using the System.Drawing.Graphics class? Or you want to use LEADTOOLS Annotation features?

For more information about the LEADTOOLS Annotation features, please see the following page:

system.drawing.graphic class needed.

The code will be something as follows:
+-------------+
 
public void TestDraw()
{
Graphics objG = MyRasterImage.CreateGdiPlusGraphics().Graphics;
Pen objP = new Pen(Color.Blue);

//Draw Rounded Rectangle
RoundRectangle(objG, objP, 100, 200, 200, 100, 10);

// Draw Polygon
objG.DrawPolygon(...);

// Draw Bezier
objG.DrawBezier(...);

}

public void RoundRectangle(Graphics objG, Pen objP, float h, float v,
float width, float height, float radius)
{
GraphicsPath objGP = new GraphicsPath();
objGP.AddLine(h + radius, v, h + width - (radius * 2), v);
objGP.AddArc(h + width - (radius * 2), v, radius * 2, radius * 2, 270, 90);
objGP.AddLine(h + width, v + radius, h + width, v + height - (radius * 2));
objGP.AddArc(h + width - (radius * 2), v + height - (radius * 2), radius * 2, radius * 2, 0, 90); // Corner
objGP.AddLine(h + width - (radius * 2), v + height, h + radius, v + height);
objGP.AddArc(h, v + height - (radius * 2), radius * 2, radius * 2, 90, 90);
objGP.AddLine(h, v + height - (radius * 2), h, v + radius);
objGP.AddArc(h, v, radius * 2, radius * 2, 180, 90);
objGP.CloseFigure();
objG.DrawPath(objP, objGP);
objGP.Dispose();
}

sorry,

I want the leadtools features

soorry Once again

If you mean that you want to create Annotation rectangle object programmatically, you can do this by using the AnnRectangleObject Class as follows:
+--------+
AnnRectangleObject rect = new AnnRectangleObject();
rect.Pen = new AnnPen(Color.Red, new AnnLength(2, AnnUnit.Pixel));
rect.Brush = new AnnSolidBrush(Color.White);
rect.Bounds = new AnnRectangle(100, 200, 400, 600, AnnUnit.Pixel);
ActiveAnnotationsForm.Automation.Container.Objects.Add(rect);
+--------+

You can create Annotation curves by using the AnnPolygonObject, AnnCurveObject, AnnPolylineObject and AnnClosedCurveObject Classes.

For more information, please refer to the LEADTOOLS .Net documentation.

hello,

Error happened at,

Automation.Container.Objects.Add(rect);

error is:Automation does not contain a defenition for Container.

What is the type of the Automation object that you use?
The type of the Automation object must be AnnAutomation class. You should use the AnnAutomation object that you define in your code.
