image translation
shift the position of an image by adding/subtracting a value to/from the X or Y coordinates
translation(image, shift_rows = 0, shift_cols = 0, padded_value = 0)
image |
a matrix, data frame or 3-dimensional array |
shift_rows |
a positive or negative integer specifying the direction that the rows should be shifted |
shift_cols |
a positive or negative integer specifying the direction that the columns should be shifted |
padded_value |
either a numeric value or a numeric vector of length 3 (corresponding to RGB). If it's not equal to 0 then the values of the shifted rows or columns will be filled with the user-defined padded_value |
If shift_rows is not zero then the image will be sifted row-wise (upsides or downsides depending on the sign). If shift_cols is not zero then the image will be sifted column-wise (right or left depending on the sign).
