[dvipdfmx] Sub-optimal diagnostic from XeTeX/xdvipdfmx when including non-existent page from PDF

[Shunsaku Hirata]

Sorry for the late reply.

I'm going to change the error message as suggested.

Thanks for your suggestion.

Thanks,

It is therefore clear that the problem lies not with "./Hoi-An vegan menu (separate pages).pdf" per se, but rather with the assumption that "./Hoi-An vegan menu (separate pages).pdf" contains four or more pages.  It would therefore be very helpful if XeTeX/xdvipdfmx could report that the problem occurred when trying to access page 4, rather than merely stating that « Image inclusion failed for "./Hoi-An vegan menu (separate pages).pdf" ».
