Method Summary

Methods

Modifier and Type	Method and Description
T	extractSamples(Line2d line, I image, int numSamples) Extract a numSamples samples along the given line in the given image.
Line2d	getSampleLine(Line2d line, I image, int numSamples) Get the a line representing the extremities of the pixels that are actually sampled.

Method Detail

extractSamples

T extractSamples(Line2d line,
               I image,
               int numSamples)

Extract a numSamples samples along the given line in the given image. Implementors may choose to interpret the line in different ways; some may sample numSamples between the start and end points, whilst others may choose different sampling points along the direction of the line.

Parameters:

line - the line

image - the image to sample from

numSamples - the number of samples

Returns:

the samples

getSampleLine

Line2d getSampleLine(Line2d line,
                   I image,
                   int numSamples)

Get the a line representing the extremities of the pixels that are actually sampled.

Parameters:

line - the line

image - the image to sample from

numSamples - the number of samples

Returns:

the sampling line
