math::gradient
Gradient(3pm) User Contributed Perl Documentation Gradient(3pm)
NAME
Math::Gradient - Perl extension for calculating gradients for colour transitions, etc.
SYNOPSIS
use Math::Gradient qw(multi_gradient);
# make a 100-point colour palette to smothly transition between 6 RGB values
my(@hot_spots) = ([ 0, 255, 0 ], [ 255, 255, 0 ], [ 127, 127, 127 ], [ 0, 0, 255 ], [ 127, 0, 0 ], [ 255, 255, 255 ]);
my(@gradient) = multi_array_gradient(100, @hot_spots);
DESCRIPTION
Math::Gradient is used to calculate smooth transitions between numerical values (also known as a "Gradient"). I wrote this module mainly to
mix colours, but it probably has several other applications. Methods are supported to handle both basic and multiple-point gradients, both
with scalars and arrays.
FUNCTIONS
gradient($start_value, $end_value, $steps)
This function will return an array of evenly distributed values between $start_value and $end_value. All three values supplied should
be numeric. $steps should be the number of steps that should occur between the two points; for instance, gradient(0, 10, 4) would
return the array (2, 4, 6, 8); the 4 evenly-distributed steps necessary to get from 0 to 10, whereas gradient(0, 1, 3) would return
(0.25, 0.5, 0.75). This is the basest function in the Math::Gradient module and isn't very exciting, but all of the other functions
below derive their work from it.
array_gradient($start_value, $end_value, $steps)
While gradient() takes numeric values for $start_value and $end_value, array_gradient() takes arrayrefs instead. The arrays supplied
are expected to be lists of numerical values, and all of the arrays should contain the same number of elements. array_gradient() will
return a list of arrayrefs signifying the gradient of all values on the lists $start_value and $end_value.
For example, calling array_gradient([ 0, 100, 2 ], [ 100, 50, 70], 3) would return: ([ 25, 87.5, 19 ], [ 50, 75, 36 ], [ 75, 62.5, 53
]).
multi_gradient($steps, @values)
multi_gradient() calculates multiple gradients at once, returning one list that is an even transition between all points, with the
values supplied interpolated evenly within the list. If $steps is less than the number of entries in the list @values, items are
deleted from @values instead.
For example, calling multi_gradient(10, 0, 100, 50) would return: (0, 25, 50, 75, 100, 90, 80, 70, 60, 50)
multi_array_gradient($steps, @values)
multi_array_gradient() is the same as multi_gradient, except that it works on arrayrefs instead of scalars (like array_gradient() is to
gradient()).
