pullqPLMSample: Interactive Sub-sampling of qPLM Data by Pixel count

In TobinH/microTransit: Quantitative Polarized Light Imaging and Analysis Tools

Interactive Sub-sampling of qPLM Data by Pixel count

Description

pullqPLMSample sub-samples a specified number of pixels from a qPLMarr object in a square ROI around an interactively selected point.

Usage

pullqPLMSample(qPLMarr, layer, pixels)

Arguments

qPLMarr	A qPLMarr object.
layer	Value from 1-3; this layer will be displayed on-screen for selecting the ROI (1 = I, 2 = theta, 3 = phi). The resulting subsample will include all of the 'stacked' layers from the qPLMarr object.
pixels	approximate number of pixels required for the sample (rounding for a square region may pull pixels more than specified by this argument).

Value

A qPLMarr object with the subsampled pixels. This object will maintain all the attributes of the original.
