You can get the files in a directory using *directory-list *and filter for
the image files using a regex.

Hi Robert,
There are some bindings for Magick in the example folder for the FFI
library.
https://github.com/racket/racket/tree/master/pkgs/racket-doc/ffi/examples
The bindings are in magic.rkt and examples of use are in use-magick.rkt

Racket has the ability to read a variety of different image files. I would go
first to 2htdp/image’s “bitmap/file” to read images. “save-image” can write
images (but only as png files). I believe there are also an array of
lower-level image manipulation functions that are likely to have a less
Alternatively, does the normal images function for Racket work? When I was
looking through the documentation I saw a lot about creating shapes but not
about using image files.

I don't know of one off hand, but I believe RacketCon 2018 (?) included a
presenter that showed a PostScript-like DSL for designers and artists. If pict

Failing that, can you show what you'd hope the syntax would look like? That

I have to do a bunch of .jpg and .png image resizings and was looking for a
programmatic way to do it. Is their a Racket DSL for this?
