Re: LaTeX - some logos print, others don't.


I've condensed the description of my problem below, so it's worth re- reading if you don't know what I'm on about.

Basically, this code:

    my $temphash;
if ( $self->{format} =~ /(postscript|pdf)/ || $self->{media} eq 'email' ) {
        $temphash{out} = $self->{OUT};
        $self->{OUT} = "$self->{tmpfile}";

from Form.pm treats the filenames logo.png and logo.eps specially, when printing invoices. It didn't around SL 2.6.21 or so.

So a user template wanting to include other graphics b0rks out. As I described in my previous reply to Chris' below comments <http:// tinyurl.com/2mjfqo>, full path names to additional graphics don't _seem_ to work for me.

  # sudo grep logo /usr/local/ledger-smb/templates/stroller/invoice.tex
\includegraphics[height=2cm]{/usr/local/ledger-smb/templates/ stroller/logo-outline} \includegraphics[height=2cm]{/usr/local/ledger-smb/templates/ stroller/logo-outline.png} \includegraphics[height=2cm]{/usr/local/ledger-smb/templates/ stroller/logo-outline.eps}

_still_ only prints out the file called "logo".

Anyway, this is a problem, because here I use the ifpdf package to determine whether to print my colour logo or my black & white one:


This is because my full-colour logo looks rubbish when printed out on my black & white laser printer. Customers get a full colour copy of the logo when I email them the PDF version of the invoice - in black & white the "outline" version of the logo looks much more professional.

Obviously, now I'm aware of the problem I can change "logo-colour.*" to "logo.*" and I'm able to print something other than "SMB-Ledger" at the top of my invoices.

To be honest, this isn't a massively big deal for me, as I only print out my own copy of the invoice on my B&W laser printer, and this just gets filed in my records, never to be seen by anyone important.

I assume that logo.png & logo.eps are treated special for security reasons. I don't entirely understand this - if someone can inject my- image.png. or .my-image.eps into both the templates directory & the template itself, then can't they as easily just overwite the original logo.* which you are trusting to be safe?

However, as I've demonstrated above, Chris' reply about the absolute path doesn't _seem_ to be correct, so there's no way I can work around it or for users to otherwise include multiple graphics in their templates.

In 1.2.2-3, you should change the LaTeX templates to use the absolute
path to any custom logos.  We cant really parse the LaTeX to know
which files to copy to /tmp/ and that would not be safe anyway.

It really frustrates me, because trying with this invoice.tex:

   top-left\hfill top-right
   \par \vfill
   bottom-left\hfill bottom-right

... the logo shipped with Ledger-SMB (I created a new templates
directory for my user, based on the demo templates; I have nor
renamed or deleted or touched in anyway the L-SMB logos) prints fine,
but my logo (logo-outline) does not.
