Hi,
How do I set pdfminorversion in LTMX. Both \pdfminorversion and
\pdfvariable minorversion fail with undefined control sequence.
Does lpdf.setversion(major, minor) work in LMTX?
It does not give an error, but it doesn't change the minor version
either.
1. A better solution for this is to add a key to \setupbackend.
2. It doesn't work because when you set the version it's too late
because ConTeXt already wrote the PDF header (the relevant code is in
lpdf-lmt.lmt).
This is a problem because when you set a PDF format the version entry is
ignored in the header (but it's correct in catalogue entry).
%% begin example
\setupbackend[format=PDF/X-1a:2003]
\starttext
Hello TeX.
\stoptext
%% end example
%% begin pdf file (snippet from the example above, compare the version
numbers)
%PDF-1.7
%ÃÏÎÔÅØÔÐÄÆ

%% end pdf file
