plot2D.zoom: Zooms into a section of an array object and plots it

In Chitran1987/StatsChitran: StatsChitran

Zooms into a section of an array object and plots it

Description

Takes in an array object, T_{m,n,p}.
Also requires centre of the zoom area, given by center and the expected zoom dimensions Del_X and Del_Y.
Then, it returns the subsetted array in accordance to the zoom requirements set by center, Del_X and Del_Y

Usage

plot2D.zoom(arr, center, Del_X, Del_Y, pl = T)
plot2D.zoom(arr, center, Del_X, Del_Y)
plot2D.zoom(arr, center, Del_X, Del_Y, pl = F)

Arguments

arr	The array object, T_{m,n,p}. Has to be a rank-3 array. p \in \{1, 2, 3\}, since T_{m,n,p} has to be 3-slice. For better understanding of structure of array, check img_2_arr.
center	Two element vector denoting the (X, Y) values of the center of the zoom-area
Del_X	The length of the zoomed image along the X-axis
Del_Y	The length of the zoomed image along the Y-axis
pl	Plots the new array if pl == T. Set to TRUE by default

Details

See the image below.

Value

The returned value is necessarily an array of the same structure as arr

Examples

library(StatsChitran)
dat <- system.file("extdata", "STM.png", package = "StatsChitran")
arr1 <- img_2_arr(source.png = dat, x.lim = c(0, 19), y.lim = c(0,19)) #The image array
arr.zoom <- plot2D.zoom(arr = arr1, center = c(16, 12), Del_X = 6, Del_Y = 6) #The zoomed in array
