3D array that represents an image with dimensions (height,width,channels) or (channels,height,width) depending on the data_format.

image_array_resize( img, height, width, data_format = c("channels_last", "channels_first") )

image_array_save( img, path, data_format = NULL, file_format = NULL, scale = TRUE )

Arguments
img

Image

data_format

Image data format ("channels_last" or "channels_first")
