setIPixels

public void setIPixels(IPixels iPixels)

IPixels bean injector. For use during configuration. Can only be called once.

projectStack

public byte[] projectStack(long pixelsId,
                           PixelsType pixelsType,
                           int algorithm,

                           int start,
                           int end)

Description copied from interface: IProjection

Performs a projection through the optical sections of a particular wavelength at a given time point of a Pixels set.

Specified by:

projectStack in interface IProjection

Parameters:

pixelsId - The source Pixels set Id.

pixelsType - The destination Pixels type. If null, the source Pixels set pixels type will be used.

algorithm - MAXIMUM_INTENSITY, MEAN_INTENSITY or SUM_INTENSITY. NOTE: When performing a SUM_INTENSITY projection, pixel values will be pinned to the maximum pixel value of the destination Pixels type.

timepoint - Timepoint to perform the projection.

channelIndex - Index of the channel to perform the projection.

stepping - Stepping value to use while calculating the projection. For example, stepping=1 will use every optical section from start to end where stepping=2 will use every other section from start to end to perform the projection.

start - Optical section to start projecting from.

end - Optical section to finish projecting.

Returns:

A byte array of projected pixel values whose length is equal to the Pixels set sizeX * sizeY * bytesPerPixel in big-endian format.

Description copied from interface: IProjection

Performs a projection through selected optical sections and optical sections for a given set of time points of a Pixels set. The Image which is linked to the Pixels set will be copied using IPixels.copyAndResizeImage(long, Integer, Integer, Integer, Integer, List, String, boolean).

Specified by:

projectPixels in interface IProjection

Parameters:

pixelsId - The source Pixels set Id.

pixelsType - The destination Pixels type. If null, the source Pixels set pixels type will be used.

algorithm - MAXIMUM_INTENSITY, MEAN_INTENSITY or SUM_INTENSITY. NOTE: When performing a SUM_INTENSITY projection, pixel values will be pinned to the maximum pixel value of the destination Pixels type.

tStart - Timepoint to start projecting from.

tEnd - Timepoint to finish projecting.

channels - List of the channel indexes to use while calculating the projection.

stepping - Stepping value to use while calculating the projection. For example, stepping=1 will use every optical section from start to end where stepping=2 will use every other section from start to end to perform the projection.

zStart - Optical section to start projecting from.

zEnd - Optical section to finish projecting.

name - Name for the newly created image. If null the name of the Image linked to the Pixels qualified by pixelsId will be used with a "Projection" suffix. For example, GFP-H2B Image of HeLa Cells will have an Image name of GFP-H2B Image of HeLa Cells Projection used for the projection.

Returns:

The Id of the newly created Image which has been projected.
