In order to use IEVision you must copy the IEVision DLL to the same folder as your executable or in any location in the system path.
You can check if the IEVision DLL is accessible by ImageEn calling IEVisionAvailable function. For example:

if not IEVisionAvailable() then
begin
  ShowMessage('This application requires the IEVision.dll plugin');
  Application.Terminate;
  exit;
end;


The ievision unit exports all interfaces and global methods, plus the IEVisionLib public field which encapsulates the factory class TIEVisionLibrary.

It is possible to encapsulate an ImageEn bitmap (TIEBitmap) inside a IEVision bitmap (TIEVisionImage), but it is necessary to change the TIEBitmap origin. For example:

ImageEnView1.IEBitmap.Origin := ieboTOPLEFT;
image := IEVisionLib.createImage(ImageEnView1.IEBitmap.Width, ImageEnView1.IEBitmap.Height,
                                 ievUINT8, 3, ImageEnView1.IEBitmap.Rowlen,
                                 ImageEnView1.IEBitmap.ScanLine[0]);

This way you can use all IEVision functions sharing the results to a TImageEnView embedded image. It is also possible to create an IEVision image from scratch and then copy it to TIEBitmap or TImageEnView.

An alternative way is to use GetIEVisionImage which sets the bitmap origin and pixelformat for you:

image := ImageEnView1.IEBitmap.GetIEVisionImage();



All IEVision objects are implemented as COM objects, so you don't need to handle object destruction (it is done automatically at runtime).
For example, if you create an IEVision image with:

image := IEVisionLib.createImage(1000, 1000, ievUINT8, 3);

You don't need to free or dispose it.
