Hi!
I wonder if/how it's possible to specify multiple image conversions. Example:
\startluacode
local format = string.format
local function degradejpg(oldname, newname)
local s = format("gm convert -strip -quality 75%% -resize '300x300>' %s
%s", oldname, newname)
os.execute(s)
end
local function degradepng(oldname, newname)
local s = format("gm convert -strip -resize '500x500>' %s %s", oldname,
newname)
os.execute(s)
end
figures.converters.jpg["degrade.jpg"] = degradejpg
figures.converters.png["degrade.png"] = degradepng
\stopluacode
\setupexternalfigures
[location=default,
%% conversion=degrade.png, %% how to use both?
conversion=degrade.jpg]
\starttext
\externalfigure [hacker]
\externalfigure [mill]
\stoptext
I'd like to avoid specifying the filetype-specific conversion with each
\externalfigure command:
%% this works, but it clutters the document and one has to check the
%% file type each time
\externalfigure [mill] [conversion=degrade.png]
