The MkIV internal mptopdf converter fails on the following minimal example. Here is the tex:

And here is the figure, which was produced with mpost 0.993 (and also converted to fig-1.pdf using the 'mptopdf' command):

Running it through MkIV with the 2013.12.26 beta (or the stable context) produces an empty frame for the inclusion of fig.1, but the correct triangle for the inclusion of fig-1.pdf. The empty frame has the correct size, so the parser is getting at least as far as the bounding box.

If I regenerate fig.1 using a recent metapost (1.803), the mps file is simpler, and it is incorporated correctly by context.

Here is the source file:

weird, there used to be a procset line ... anyhow, maybe this works ok at your end (meta-pdf.lua): local function parse(m_data) if find(m_data,"%%%%BeginResource: procset mpost") then -- report_mptopdf("using sparse scanner, case 1") lpegmatch(captures_new,m_data) elseif find(m_data,"%%%%BeginProlog%s*%S+(.-)%%%%EndProlog") then -- report_mptopdf("using sparse scanner, case 2") lpegmatch(captures_new,m_data) else -- report_mptopdf("using verbose ps scanner") lpegmatch(captures_old,m_data) end end -- ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
