create

Creates RasterData from 2D or 3D collection.

iterable

2D or 3D collection.

(M, N): an image with scalar data. The values are mapped to colors (greys by default) using normalization. See parameters norm, vmin, vmax.
(M, N, 3): an image with RGB values (0-1 float or 0-255 int).
(M, N, 4): an image with RGBA values (0-1 float or 0-255 int).

Creates RasterData from 2D or 3D array.

arr

2D or 3D array.

(M, N): an image with scalar data. The values are mapped to colors (greys by default) using normalization. See parameters norm, vmin, vmax.
(M, N, 3): an image with RGB values (0-1 float or 0-255 int).
(M, N, 4): an image with RGBA values (0-1 float or 0-255 int).

fun create(arr: ByteArray, width: Int, height: Int, nChannels: Int): RasterData

Creates RasterData from 1D array with pixel data.

arr

Array of Numbers (0-1 float or 0-255 int). Expected size width * height * nChannels.

width

Width of the image in pixels.

height

Height of the image in pixels.

nChannels

Number of channels per pixel.

1: an image with scalar data. The values are mapped to colors (greys by default) using normalization. See parameters norm, vmin, vmax.
3: an image with RGB values (0-1 float or 0-255 int).
4: an image with RGBA values (0-1 float or 0-255 int).
