Hi,
I am trying to use a combination figure with luacode (both with latest
MKIV and LMTX).
However, the figures do not line up in the grid of the combination.
I get the correct result with examples 1 and 2 below, but example 3
using lua functions for combination and externalfigure is what I wanted
to use in the first place.
MWE:
\starttext
\startluacode
-- Combination 1
context.startplacefigure({title = "Figure"})
context.startcombination({nx = "2", ny = "2"},
"\\externalfigure[cow][width=50mm]","Caption 1",
"\\externalfigure[cow][width=50mm]","Caption 2",
"\\externalfigure[cow][width=50mm]","Caption 3",
"\\externalfigure[cow][width=50mm]","Caption 4"
)
context.stopcombination()
context.stopplacefigure()
-- Combination 2
context.startplacefigure({title = "Figure"})
context.startcombination({nx = "2", ny = "2"},
"Picture 1","Caption 1",
"Picture 2","Caption 2",
"Picture 3","Caption 3",
"Picture 4","Caption 4"
)
context.stopcombination()
context.stopplacefigure()
-- Combination 3
context.startplacefigure({title = "Figure"})
context.startcombination({nx = "2", ny = "2"},
context.externalfigure({"cow"},{width = "50mm"}),"Caption 1",
context.externalfigure({"cow"},{width = "50mm"}),"Caption 2",
context.externalfigure({"cow"},{width = "50mm"}),"Caption 3",
context.externalfigure({"cow"},{width = "50mm"}),"Caption 4"
)
context.stopcombination()
context.stopplacefigure()
\stopluacode
\stoptext
Any hints on what I am doing wrong in example 3?
as in any prodedural language a function as argument gets immediately
executed so you need to delay:
context.startplacefigure({title = "Figure"})
context.startcombination({nx = "2", ny = "2"},
context.delayed.externalfigure({"cow"},{width = "50mm"}),
"Caption 1",
context.delayed.externalfigure({"cow"},{width = "50mm"}),
"Caption 2",
context.delayed.externalfigure({"cow"},{width = "50mm"}),
"Caption 3",
context.delayed.externalfigure({"cow"},{width = "50mm"}),
"Caption 4"
)
context.stopcombination()
context.stopplacefigure()
(this is why encoding complex documents completely in a scrtipt language
is non trivial and why for instance these template systems are there
because these accumulate)
