r - Error with repeated image_crop() with magick package -


i using magick package process images. need crop them twice. second time crop, error.

here minimal working example example

library("magick") library("magrittr") img <- image_read(system.file("img", "rlogo.png", package="png")) img %>% image_crop("50x76+50+0") %>% image_crop("10x76+0+0")

which gives error:

error in magick_image_crop(image, geometry) :
magick: geometry not contain image `/home/gbsrt/r/x86_64-pc-linux-gnu-library/3.4/png/img/rlogo.png' @ warning/transform.c/cropimage/574

i think understand why getting error, , need call +repage, cannot work out how through magick package.
