Package bdv.viewer.render

Class SimpleVolatileProjector<A,B>

java.lang.Object

bdv.viewer.render.SimpleVolatileProjector<A,B>

Type Parameters:

A - pixel type of the source RandomAccessible.

B - pixel type of the target RandomAccessibleInterval.

All Implemented Interfaces:

VolatileProjector

public class SimpleVolatileProjector<A,B>
extends Object
implements VolatileProjector

An VolatileProjector, that renders a target 2D RandomAccessibleInterval by copying values from a source RandomAccessible. The source can have more dimensions than the target. Target coordinate (x,y) is copied from source coordinate (x,y,0,...,0).

Constructor Detail

SimpleVolatileProjector

public SimpleVolatileProjector(net.imglib2.RandomAccessible<A> source,
                               net.imglib2.converter.Converter<? super A,B> converter,
                               net.imglib2.RandomAccessibleInterval<B> target)

Create new projector with the given source and a converter from source to target pixel type.

Parameters:

source - source pixels.

converter - converts from the source pixel type to the target pixel type.

target - the target interval that this projector maps to

Method Detail

cancel

public void cancel()

Description copied from interface: VolatileProjector

Abort VolatileProjector.map() if it is currently running.

Specified by:

cancel in interface VolatileProjector

getLastFrameRenderNanoTime

public long getLastFrameRenderNanoTime()

Description copied from interface: VolatileProjector

How many nano-seconds did the last VolatileProjector.map() take.

Specified by:

getLastFrameRenderNanoTime in interface VolatileProjector

Returns:

time needed for rendering the last frame, in nano-seconds.

isValid

public boolean isValid()

Specified by:

isValid in interface VolatileProjector

Returns:

true if all mapped pixels were valid.

map

public boolean map(boolean clearUntouchedTargetPixels)

Render the 2D target image by copying values from the source. Source can have more dimensions than the target. Target coordinate (x,y) is copied from source coordinate (x,y,0,...,0).

Check after each line whether rendering was canceled.

Specified by:

map in interface VolatileProjector

Returns:

true if rendering was completed (all target pixels written). false if rendering was interrupted.
