Interface RenderResult

All Known Implementing Classes:

BufferedImageRenderResult

public interface RenderResult

Provides the renderer with a target image (RandomAccessibleInterval<ARGBType>) to render to. Provides the RenderTarget with the rendered image and transform etc necessary to display it.

Method Summary

Modifier and Type	Method	Description
double	getScaleFactor()	Get the scale factor from target coordinates to screen resolution.
net.imglib2.RandomAccessibleInterval<net.imglib2.type.numeric.ARGBType>	getTargetImage()	Get the image to render to.
net.imglib2.realtransform.AffineTransform3D	getViewerTransform()	Get the viewer transform used to render image.
void	init(int width, int height)	Allocate storage such that getTargetImage() holds an image of width * height.
void	patch(RenderResult patch, net.imglib2.Interval interval, double ox, double oy)	Fill in interval with data from patch, scaled by the relative scale between this RenderResult and patch, and shifted such that (0,0) of the patch is placed at (ox,oy) of this RenderResult
void	setScaleFactor(double scaleFactor)	Set the scale factor from target coordinates to screen resolution.
void	setUpdated()	Notify that the target image data was changed.

Method Detail

init

void init(int width,
          int height)

Allocate storage such that getTargetImage() holds an image of width * height.

(Called by the renderer.)

getTargetImage

net.imglib2.RandomAccessibleInterval<net.imglib2.type.numeric.ARGBType> getTargetImage()

Get the image to render to.

(Called by the renderer.)

Returns:

the image to render to

getViewerTransform

net.imglib2.realtransform.AffineTransform3D getViewerTransform()

Get the viewer transform used to render image. This is with respect to the screen resolution (doesn't include scaling).

(Called by the renderer to set the transform.)

getScaleFactor

double getScaleFactor()

Get the scale factor from target coordinates to screen resolution.

setScaleFactor

void setScaleFactor(double scaleFactor)

Set the scale factor from target coordinates to screen resolution.

patch

void patch(RenderResult patch,
           net.imglib2.Interval interval,
           double ox,
           double oy)

Fill in interval with data from patch, scaled by the relative scale between this RenderResult and patch, and shifted such that (0,0) of the patch is placed at (ox,oy) of this RenderResult

Note that only data in interval will be modified, although the scaled and shifted patch might fall partially outside.

setUpdated

void setUpdated()

Notify that the target image data was changed.

(Called by the renderer.)
