Bug #128674 for PDF-API2: error "requested cmap '' not installed" with many CJK fonts

PDF::API2 version 2.033 Font::TTF version 1.06 Perl version 5.20.2 Sample code: #!/usr/bin/env perl use PDF::API2; $pdf = PDF::API2->new(); $pdf->page(); $pdf->ttfont("NotoSansJP-Medium.otf"); # downloaded from here: # https://github.com/googlei18n/noto-cjk/blob/master/NotoSansJP-Medium.otf dies with: requested cmap '' not installed at /Users/Shared/perlbrew/perls/perl-5.20.2/lib/site_perl/5.20.2/PDF/API2/Resource/CIDFont/TrueType/FontFile.pm line 27. About a third of the CJK fonts I have don't work with PDF::API2. I used Noto Sans JP in the above example because it's freely available, but it's not the only one, and at least one other PostScript-flavored OTF font that I own does work (DFKyoKaShoStd-W4.otf). Is there a workaround or a fix? -j

replace the section

#/lib/PDF/API2/Resource/CIDFont/TrueType/FontFile.pm #in sub new #-------------------------------------------

if(defined $data->{cff}->{ROS}) { my %cffcmap=( 'Adobe:Japan1'=>'japanese', 'Adobe:Korea1'=>'korean', 'Adobe:CNS1'=>'traditional', 'Adobe:GB1'=>'simplified', 'Adobe:Identity'=>'identity', # NEW CMAP ); my $ccmap=_look_for_cmap($cffcmap{"$data->{cff}->{ROS}->[0]:$data->{cff}->{ROS}->[1]"}); $data->{u2g}=$ccmap->{u2g}; $data->{g2u}=$ccmap->{g2u}; } else

#-------------------------------------------

and create a new cmap file:

#/lib/PDF/API2/Resource/CIDFont/CMap/identity.cmap #------------------------------------------- $cmap->{identity}={ 'ccs' => [ 'Adobe', # registry 'Identity', # ordering 0, # supplement ], 'cmap' => { # perl unicode maps to adobe cmap (TBD) 'ident' => [ 'ident', 'Identity' ], }, 'g2u' => [ 0x0000 .. 0xffff ], 'u2g' => { map { $_ => $_ } (0x0000 .. 0xffff) } };

#-------------------------------------------

it could be that the g2u/u2g data does not work and you have to include the raw array and map instead.

Hi Alfred, Good to see you're still active in this area! Unless "Identity" is a very different beast than the other CMaps, I suspect that this won't work. For example, u2g[x20] = space = GId[1], and the map is not monotonically increasing. Can someone show that it does work? Per https://github.com/PhilterPaper/Perl-PDF-Builder/issues/98, I have found some CMap sources and tools from Adobe, but they don't seem to have the u2g/g2u information needed for the .cmap files used here. Do you have an idea of how to generate .cmap files? I'm thinking in terms of a tool that would take an Adobe CMap file that someone wants to use and generating a .cmap file from it. In any case, it would probably still be a good idea to add Adobe:Identity to the list. regards, Phil Perry

For PDF::Builder, I have updated FontFile.pm to look in .cmap files (if -usecmf=>1), then in the list of Platform/Encodings given by -cmaps (or its default list), then using find_ms(), and finally back to .cmap files (regardless of -usecmf setting). One of those should hopefully find a workable CMap! There is also a -debug flag to show diagnostic information in the hunt for a CMap. I am leaving the PDF::Builder ticket open for now as a reminder that the four .cmap files are still in need of updating, and I have not yet found a suitable data source (Unicode/glyphID mapping) to generate new .cmap files. Many thanks to Alfred Reibenschuh (original PDF::API2 author) and Bob Hallissy (Font::TTF author) for their assistance.
