public class IltTinyImageBaseRendererFactory extends IltAbstractImageBaseRendererFactory
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 done 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 first draw occurs.
It is easy to create a new tiny representation type with the following code:
IltObject.TinyType newType = new IltObject.TinyType(YOUR_NEW_TYPE_NAME); try { Image img = null; URL url = new URL("file","",YOUR_IMAGE_FILE_NAME); img = getImage(url); if (img != null) { IltTinyImageBaseRendererFactory factory = new IltTinyImageBaseRendererFactory( img , YOUR_IMAGE_PARAMETERS ); IltSettings.SetValue("Object.TinyType.YOUR_NEW_TYPE_NAME.Renderer" , factory ); } } catch (Exception e) {e.printStackTrace();}
Note: YOUR_NEW_TYPE_NAME
should be replaced by
the String of your choice.
Note: YOUR_IMAGE_FILE_NAME
should be replaced by
the appropriate String to create an URL object for your image.
Note: YOUR_IMAGE_PARAMETERS
is optional.
Note: To obtain YOUR_IMAGE_PARAMETERS
, follow these steps:

IltTinyImageBaseRendererFactory.BaseRenderer
This implementation of base renderer can draw a modified version of the
sourceImage (given as parameter of the constructor of the

Using this constructor is equivalent to
IltTinyImageBaseRendererFactory(sourceImage,200,50,128,false)
.
public IltTinyImageBaseRendererFactory()
IltTinyImageBaseRendererFactory
.
The following default values are used:
200
50
128
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.
