Using the Aphelion™ ActiveX Components (cont'd)

Integrating Image Processing capability into an application has never been so simple. Let's just guide you through a few steps showing how to develop a Visual J++ application which calls for the Aphelion ActiveX components.

1) Create a new Project

After starting Visual J++, create a new Windows Application

2) Insert the ActiveX components

• Select the Aphelion components to insert in the form

• Then, create a Visual J++ form, and insert the components. In our example, we placed the ApxImageDisplay and the ApxImage components to display an image.

• Visual J++ creates the associated packages: apximage and apximagedisplay

3) Insert ApxObjects ActiveX Control and ATL Control

• Add COM Wrapper (Same as References in Visual Basic)

• Select ApxObjects and ATL

• Visual J++ creates 3 new packages: apxobjects, atl and stdole2

4) Implement the Application.

• The following code will load the image Blood.tif from the disk, and will display it in the ApxImageDisplay control:

5) Final Step

• Build the application and run it.

With the Aphelion ActiveX components, developing imaging applications has never been so easy, and so much fun.

Differences between Visual Basic / Visual C++ and Visual J++:

Using the ApxImage and ApxImageDisplay Controls to preview an image

Visual C++ Code

ApxImage1->Read("Blood.tif");
IDispatchPtr iDispatch(ApxImage1) ;
ApxImageDisplay1->put_Content(iDispatch);

Visual Basic Code

ApxImage1.Read "Blood.tif"
ApxImageDisplay1.Content = ApxImage1.Object

Visual J++ Code

this.apxImage1.Read("C:\\Blood.tif");
this.apxImageDisplay1.setContent(this.apxImage1.getOcx());
