image_to_array.Rd
3D array that represents an image with dimensions (height,width,channels) or (channels,height,width) depending on the data_format.
image_to_array(img, data_format = c("channels_last", "channels_first")) 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)
img | Image |
---|---|
data_format | Image data format ("channels_last" or "channels_first") |
height | Height to resize to |
width | Width to resize to |
path | Path to save image to |
file_format | Optional file format override. If omitted, the format to use is determined from the filename extension. If a file object was used instead of a filename, this parameter should always be used. |
