Image Resource Model

The Image resource model supports the information type Image.

The Image information type is a logical two-dimensional bitmap image useful for applications that require simple image displays such as web applications.

A tutorial describes how to program an image processing pipeline in DPML.

Services and Functions

The primary services include:

Service	Description
active:imageBackground	Set the background color in an image resource.
active:imageCrop	Crop an image resource based on a specification.
active:imageNoise	Add a specific level of dithered noise to an image resource.
active:imageProperties	Returns an XML report containing properties of an image resource.
active:imageQuantize	Quantize an image resource to reduce its color palette size.
active:imageRotate	Rotate an image resource by an specified angle.
active:imageScale	Scale an image resource to specified dimensions.
active:imageSerialize	Generate a binary stream of the image resource in a specified format such as PNG or JPEG.
active:imageSVG2Image	Create an image resource from an SVG (XML)resource.

Ancillary functions include:

Service	Description
active:imageSVG2PNG	Create a PNG bitmap image directly from an SVG resource.
active:imageText2PNG	Create a PNG bitmap image that displays formatted text directly from a text resource.
active:imageXChart2PNG	Create a PNG bitmap image of charts directly from XML formatted data.

Physical Representations

The physical representation used for images is org.ten60.util.image.ImageAspect which is a simple wrapper for the Java 2D image class java.awt.Image.

Transrepresentations

Images may be serialized and parsed from external standard formats supplied as a binary stream.
