Detailed Description

A kind of draw adapter supporting drawing in a System.Drawing.Graphics object.

This class implements IDisposable and it is required to use it in a using block.

Constructor & Destructor Documentation

ESystemDrawingDrawAdapter() [1/2]

eVision.ESystemDrawingDrawAdapter.ESystemDrawingDrawAdapter

(

Graphics

graphics

)

Initialize an instance of ESystemDrawingDrawAdapter from a System.Drawing.Graphics object.

Parameters

graphics

A System.Drawing.Graphics object. An HDC will be acquired from this object during the class initialization and will be released when the Dispose() method is called.

ESystemDrawingDrawAdapter() [2/2]

eVision.ESystemDrawingDrawAdapter.ESystemDrawingDrawAdapter

(

Image

image

)

Initialize an instance of ESystemDrawingDrawAdapter to draw on a System.Drawing.Image object.

Parameters

image

A System.Drawing.Image object.

Member Function Documentation

Dispose() [1/2]

void eVision.ESystemDrawingDrawAdapter.Dispose

(

)

Flushes all the drawing operations that were performed and properly release all ressources.

If the constructor taking a System.Drawing.Graphics object was used this method does not call the Dispose() method on that System.Drawing.Graphics object.

Dispose() [2/2]

virtual void eVision.ESystemDrawingDrawAdapter.Dispose ( bool disposing )
