public class IltCardImageBaseRendererFactory extends IltAbstractImageBaseRendererFactory
Note: Image processing carried out only if necessary. This means that when a new type is defined, no memory or CPU is used. The real processing and allocation are performed only the first time the image is drawn.
You can easily create a new card type with the following code:
IltCard.Type newType = new IltCard.Type(YOUR_NEW_TYPE_NAME); try { Image img = null; URL url = new URL("file","",YOUR_IMAGE_FILE_NAME); img = getImage(url); if (img != null) { IltCardImageBaseRendererFactory factory = new IltCardImageBaseRendererFactory( img , YOUR_IMAGE_PARAMETERS ); IltSettings.SetValue("Card.Type.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:

IltCardImageBaseRendererFactory.BaseRenderer
This implementation of a base renderer can draw a modified version of the
sourceImage (provided as parameter to the constructor of the

Using this constructor is equivalent to
IltImageCardBaseRendererFactory(sourceImage,200,50,128,false)
.
public IltCardImageBaseRendererFactory()
IltCardImageBaseRendererFactory
.
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.
