Property Value

The displayed image's memory device context.

Explanation

The ImageHdc property refers to the displayed image's memory device context. This property allows you to draw graphics and text on an image using one of the methods contained in ImageKit.PrintDraw. The ImageHdc property may be used when the Edit.EditEnable property is set to true, thus enabling the ImageKit10's edit mode, and when a raster image is set in the ImageHandle property. Note that in edit mode, graphics and text are drawn to the image data in the memory. To save those changes to the image data, execute the Edit.Modify method.

The ImageHdc property corresponds to the HdcMemory property in earlier versions of the ImageKit.
