public void resendTopDownLeftRight(ImageProducer ip)
ImageConsumer
.
When an ImageConsumer
being fed
by an instance of this ImageFilter
requests a resend of the data in TDLR order,
the FilteredImageSource
invokes this method of the ImageFilter
.
An ImageFilter
subclass might override this method or not,
depending on if and how it can send data in TDLR order.
Three possibilities exist:
ImageProducer
using this filter as the requesting ImageConsumer
.
This behavior
is appropriate if the filter can determine
that it will forward the pixels
in TDLR order if its upstream producer object
sends them in TDLR order.
ip
- the ImageProducer that is feeding this instance of
the filter - also the ImageProducer that the request should be
forwarded to if necessaryNullPointerException
- if ip
is nullImageProducer.requestTopDownLeftRightResend(java.awt.image.ImageConsumer)
