jdk.awt.image.renderable.RenderableImageProducer — clojure-interop/java.awt 1.0.5

An adapter class that implements ImageProducer to allow the asynchronous production of a RenderableImage. The size of the ImageConsumer is determined by the scale factor of the usr2dev transform in the RenderContext. If the RenderContext is null, the default rendering of the RenderableImage is used. This class implements an asynchronous production that produces the image in one thread at one resolution. This class may be subclassed to implement versions that will render the image using several threads. These threads could render either the same image at progressively better quality, or different sections of the image at a single resolution.

->renderable-image-producer clj

(->renderable-image-producer rdbl-image rc)

Constructor.

Constructs a new RenderableImageProducer from a RenderableImage and a RenderContext.

rdbl-image - the RenderableImage to be rendered. - java.awt.image.renderable.RenderableImage rc - the RenderContext to use for producing the pixels. - java.awt.image.renderable.RenderContext

add-consumer clj

(add-consumer this ic)

Adds an ImageConsumer to the list of consumers interested in data for this image.

ic - an ImageConsumer to be added to the interest list. - java.awt.image.ImageConsumer

consumer? clj

(consumer? this ic)

Determine if an ImageConsumer is on the list of consumers currently interested in data for this image.

ic - the ImageConsumer to be checked. - java.awt.image.ImageConsumer

returns: true if the ImageConsumer is on the list; false otherwise. - boolean

remove-consumer clj

(remove-consumer this ic)

Remove an ImageConsumer from the list of consumers interested in data for this image.

ic - the ImageConsumer to be removed. - java.awt.image.ImageConsumer

request-top-down-left-right-resend clj

(request-top-down-left-right-resend this ic)

Requests that a given ImageConsumer have the image data delivered one more time in top-down, left-right order.

ic - the ImageConsumer requesting the resend. - java.awt.image.ImageConsumer

run clj

(run this)

The runnable method for this class. This will produce an image using the current RenderableImage and RenderContext and send it to all the ImageConsumer currently registered with this class.

set-render-context clj

(set-render-context this rc)

Sets a new RenderContext to use for the next startProduction() call.

rc - the new RenderContext. - java.awt.image.renderable.RenderContext

start-production clj

(start-production this ic)

Adds an ImageConsumer to the list of consumers interested in data for this image, and immediately starts delivery of the image data through the ImageConsumer interface.

ic - the ImageConsumer to be added to the list of consumers. - java.awt.image.ImageConsumer
