magick to opencv

[jwijffels]

I'm using this package a lot to parse out data from Transkribus and get the text lines in order to build some handwritten text recognition models.
For the data preparation there, I regularly switch between tools part of magick and tools part of opencv, normally I do this now as follows, it would be nice to have something more native in opencv.

magick_to_opencv <- function(img){
  p <- tempfile()
  on.exit({
    if(file.exists(p)){
      file.remove(p) 
    }
  })
  magick::image_write(img, path = p)
  image <- opencv::ocv_read(p)
  image
}

Go for it, you have write access :P Maybe keep the magick dependency a Suggets though, we don't want to make things too heavy to install.

Yes, I know, just putting this here as a reminder to myself.

Just stumbled over this issue, I have a conversion function here: JanMarvin@269433e. The config part was not straight forward, but maybe its useful for you.
