Grid::Transform Description

Grid::Transform is a Perl module with fast grid transformations. Grid::Transform is a Perl module with fast grid transformations.SYNOPSIS use Grid::Transform; $g = Grid::Transform->new(, rows=>5); $g->rotate_270->flip_vertical; print join(' ', $g->grid), "n";The Grid::Transform module provides fast methods to transform a grid of arbitrary data types.METHODS$g = Grid::Transform->new( @grid, rows=>num, columns=>num )Creates a new Grid::Transform object. The first argument is a reference to a 1-dimensional array representing a 2-dimensional "row major" (row by row) grid. (A column major grid is simply the counter transpose of a row major one.) The grid may be composed of arbitrary data types. The original array is never modified- all transformations operate on a copy.At least one dimension must be specified. If the grid and dimensions do not produce a rectangular grid extra empty elements ("") will be added to the grid.$g2 = $g->copyReturns a copy of the original Grid::Transform object.These methods get or set the grid attributes:@grid = $g->grid $grid = $g->grid @grid = $g->grid( @grid )In list context, returns an array representing the current grid. In scalar context, returns a reference to the array. Accepts an array reference representing a new grid. The new grid will be resized if the dimensions of the previous grid do not match.$g->rows $g->rows( $num )Returns the current number of rows.$g->columns $g->cols $g->columns( $num )Returns the current number of columns.All transform methods return the Grid::Transform object, so transforms can be chained.$g->rotate_90 $g->rotate90Rotates the grid 90 degrees clock-wise. a b c d e f g h i j k l a b c d i e a | e f g h -> j f b i e a j f b k g c l h d i j k l k g c l h d$g->rotate_180 $g->rotate180Rotates the grid 180 degrees clock-wise. a b c d e f g h i j k l a b c d l k j i | e f g h -> h g f e l k j i h g f e d c b a i j k l d c b a$g->rotate_270 $g->rotate270Rotates the grid 270 degrees clock-wise. a b c d e f g h i j k l a b c d d h l | e f g h -> c g k d h l c g k b f j a e i i j k l b f j a e i$g->flip_horizontal $g->mirror_horizontalFlips the grid across the horizontal axis. a b c d e f g h i j k l a b c d i j k l | e f g h -> e f g h i j k l e f g h a b c d i j k l a b c d$g->flip_vertical $g->mirror_verticalFlips the grid across the vertical axis. a b c d e f g h i j k l a b c d d c b a | e f g h -> h g f e d c b a h g f e l k j i i j k l l k j i$g->transposeFlips the grid across the vertical axis and then rotates it 90 degress clock-wise. a b c d e f g h i j k l a b c d l h d | e f g h -> k g c l h d k g c j f b i e a i j k l j f b i e a$g->counter_transpose $g->countertransposeFlips the grid across the horizontal axis and then rotates it 90 degrees clock-wise. a b c d e f g h i j k l a b c d a e i | e f g h -> b f j a e i b f j c g k d h l i j k l c g k d h l$g->fold_rightFolds the columns to the right. a b c d e f g h i j k l a b c d b c d a | e f g h -> f g e h b c a d f g e h j k i l i j k l j k i l$g->fold_leftFolds the columns to the left. a b c d e f g h i j k l a b c d d a c b | e f g h -> h e g f d a c b h e g f l i k j i j k l l i k j Requirements: · Perl
