@pocmatos I agree it’s only useful as a temporary workaround. Better bet would probably be to use pkg API to achieve your goal.

Thank you for the help. I was able to figure out how the pattern matching works to bind a value thanks to digging into @lexi.lambda’s functional-lib code. Good stuff!

@mflatt I saw in your commit message for https://github.com/racket/slideshow/commit/66e7717b4e879232f523d6dc9262ee51478fd499 that “no one uses [size-in-pixels] anymore,” but I’m not clear why not or if there’s a better way to use photos/raster images in #lang slideshow.

Photos normally scale fine with smoothing. And I think most people avoid raster images or let them scale, too.

Ok, that simplifies things a lot. Should this be noted in http://docs.racket-lang.org/slideshow/Creating_Slide_Presentations.html#(part._display-size) and the docs for size-in-pixels?
