All Implemented Interfaces:

IltBaseRendererFactory

public class IltLogicalImageBaseRendererFactory
extends IltAbstractImageBaseRendererFactory

This class lets you easily create new types of logical representations based on a single image. For example, the image for the new logical representation of a network element can be an image file (with or without transparency). This class performs the necessary processing on the given image to generate all the representations corresponding to the different base styles and alarm colors.

Note: Image processing is performed only if necessary. In other words, when a new type is defined, no memory or CPU is used. The real processing and allocation are performed when the image is drawn for the first time.

It is easy to create a new logical representation type with the following code:

 IltObject.LogicalType newType = new IltObject.LogicalType(YOUR_NEW_TYPE_NAME);
 try {
   Image img = null;
   URL url = new URL("file","",YOUR_IMAGE_FILE_NAME);
   img = getImage(url);
   if (img != null) {
     IltLogicalImageBaseRendererFactory factory = new IltLogicalImageBaseRendererFactory( img , YOUR_IMAGE_PARAMETERS );
     IltSettings.SetValue("Object.LogicalType.YOUR_NEW_TYPE_NAME.Renderer" , factory );
   }
 } catch (Exception e) {e.printStackTrace();}
 

Note: YOUR_NEW_TYPE_NAME should be replaced with the String of your choice.

Note: YOUR_IMAGE_FILE_NAME should be replaced with the appropriate String to create a URL object for your image.

Note: YOUR_IMAGE_PARAMETERS is optional.

Note: To obtain YOUR_IMAGE_PARAMETERS, follow these steps:

• Run the Image Color Tuner application located in the samples/framework/imagecolortuner/ directory of JTGO.
• Load the image file you want to use for your new object type by clicking the "Load Image..." button.
• Customize the image rendering using the provided sliders for the different base styles and alarm colors.
• Display the Java source code corresponding to your new type using the "View Source..." button. The constructor of the base renderer factory contains the current display parameters.

Since:

JTGO 4.0

IltLogicalImageBaseRendererFactory

public IltLogicalImageBaseRendererFactory(Image sourceImage,
                                          int brightThreshold,
                                          int darkThreshold,
                                          int normGray)

Creates a new IltLogicalImageBaseRendererFactory.

Parameters:

sourceImage - The image to be processed to create the different BaseStyle representations.

brightThreshold - The threshold (0..255) used for bright colors when computing the NoTraffic representation.

darkThreshold - The threshold (0..255) used for dark colors when computing the NoTraffic representation.

normGray - The gray level (0..255) used when computing the alarm CarryingTraffic representation.

IltLogicalImageBaseRendererFactory

public IltLogicalImageBaseRendererFactory(Image sourceImage,
                                          int brightThreshold,
                                          int darkThreshold,
                                          int normGray,
                                          boolean dottedBorderVisible)

Creates a new IltLogicalImageBaseRendererFactory.

Parameters:

sourceImage - The image to be processed to create the different BaseStyle representations.

brightThreshold - The threshold (0..255) used for bright colors when computing the NoTraffic representation.

darkThreshold - The threshold (0..255) used for dark colors when computing the NoTraffic representation.

normGray - The gray level (0..255) used when computing the alarm CarryingTraffic representation.

dottedBorderVisible - Indicates whether an additional dotted border is to be drawn around the base.

IltLogicalImageBaseRendererFactory

public IltLogicalImageBaseRendererFactory(Image sourceImage)

Creates a new IltLogicalImageBaseRendererFactory.

Using this constructor is equivalent to IltLogicalImageBaseRendererFactory(sourceImage,200,50,128,false).

IltLogicalImageBaseRendererFactory

public IltLogicalImageBaseRendererFactory()

Creates a new IltLogicalImageBaseRendererFactory.

The following default values are used:

• Bright color threshold: 200
• Dark color threshold: 50
• Normal gray: 128
• Dotted border visible: false

The source image must be specified using method IltAbstractImageBaseRendererFactory.setSourceImage(Image) or IltAbstractImageBaseRendererFactory.setSourceImageName(String) before using this renderer factory.

The renderer factory parameters shall be specified before using this renderer factory for the first time. Once the renderer factory is in use, modifying these parameters will have no effect on the object representation.

Since:

JViews 7.5
