cat(readLines(f), sep = "\n")
sourceCpp(f)

## 
## Step 2: 
## Convert image from jpeg to BMP3 format as ine dlib_surf function, 
##   we assume the file is in BMP3 format 
library(magick)
f <- system.file("extdata", "cruise_boat.jpeg", package = "dlib")
img <- image_read(path = f)
img 
f_bmp <- tempfile(fileext = ".bmp")
image_write(img, path = f_bmp, format = "BMP3")
