But - your pdf is pure raster / image data.
maybe the pdf is saved with some image compression that is not read properly by rhino.
convert pdf to jpg or png will do it

left - import pdf - right import jpg

hope this helps - kind regards - tom

thanks i have workarounded it, just reported an obvious bug because it should import it correctly no matter what kind of pdf it is

Thanks, Ivan -

Looks like this file uses JBIG2 encoding. I’ll see what it will take to add support for this type of bitmap.
