Hello,
I am currently trying to replace the Java Code of pax to Lua
to get a more portable version, which is easier to install.
Therefore, I am experimenting with the epdf library of LuaTeX
BTW, the manual has a typo:
<Catalog>:isOK() => <Catalog>:isOk()
The main problem is getting the destinations of a PDF document:
<Catalog>:getDests() *always* returns the null object:
Test file "getdests.lua":
filename = arg[1]
print('filename: ' .. filename)
doc = epdf.open(filename)
catalog = doc:getCatalog()
dests = catalog:getDests()
print('type(dests): ' .. type(dests))
print('getType(): ' .. dests:getType())
print('getTypeName(): ' .. dests:getTypeName())
Running: texlua getdests.lua filetotest.pdf
filetotest.tex, generated by "luatex --ini filetotest.tex":
\catcode`\{=1
\catcode`\}=2
\ifx\directlua\undefined
\else
\directlua{tex.enableprimitives('', tex.extraprimitives())}
\fi
\pdfoutput=1
\pdfobjcompresslevel=0
\shipout\hbox{%
\pdfdest name{mydest} xyz\relax\vrule width 10bp height 10bp\relax
}
\end
filetotest.pdf contains:
6 0 obj
<</Names[(mydest) 4 0 R]/Limits[(mydest) (mydest)]>>
endobj
7 0 obj
<</Dests 6 0 R>>
endobj
8 0 obj
<</Type/Catalog/Pages 5 0 R/Names 7 0 R>>
endobj
Why does getDests() returns the null object?
Do I have to parse the destination name tree manually to get
the destination names?
Yours sincerely
Heiko Oberdiek
