(planet gcr/render-pdf) now implements more of the libpoppler
glib API. You can now render PDF files to picts or bitmap%s,
gather the locations of all letters on the page, or can search
for strings

Hm. What I meant was, is there a way to do that without
rasterization? I intended to use this for rendering posters,
where a 3MB 2000dpi image is less desirable than a few
line-drawing commands. It would be lovely to be able to rotate
and scale PDFs with slidehsow/pict without converting them to

Sure, but I mean, is there a better way to get at a dc<%>'s cairo
context than (require racket/draw/private/local) ? From what I
understand, those areas aren't meant to be used by third-party
libraries, and definitely not by planet packages. Not all dc<%>s
are even backed by cairo contexts...

Done! ...Sort of.
Put a 'test.pdf' in (current-directory) and try this out:
(require slideshow/pict
(planet gcr/pdf-render))
(show-pict (rotate (pdf-page->pict "./test.pdf" 0)
(* 0.25 pi)))
I'm not rasterizing to a bitmap% or anything lik
Hi Michael,
It would be great if you turned it into a Planet package. I had no immediate
need for pdfs, so I put it on hold.
The code attached to the old message rendered the pdf into a png on disc,
and then loaded the png as a snip.
Since then Matthew added get-handle to Racket, so now one can
This is wonderful. Do you mind if I publish a planet package
using this code?

Looks like Poppler is the way

You might be able to implement this using Poppler.

I think pdf-dc% objects are for producing pdfs, not rendering t
Is it possible to display pdfs in snips without converting them to bitmaps?
I can see that pdf-drawing contexts are supported, but can't
find anything to display them.
