    <p>I working with database of documents, contents from 5 to 20 pages of text data each.<br> I have three tasks:</p> <ol> <li>To make multilingual output as PDF document. Texts in UTF8 and may content content in english, french, german, russian etc. and combinations like translations.</li> <li>To add an automatic typography in PDF, which means kerning and replacement combination of letters by Unicode characters.</li> <li>I have MinionPro-xxx.otf (10 ligatures) font for my job.</li> </ol> <p>I tried to use PHP Cphf library by Wayne Munro (pdf@ros.co.nz) and I have added a lot of regular expressions to it. I have added a lot of PDF text formatting operators, like <code>Ts, TL, T*, Tc, Tw, Tz</code> and I almost done, but I can not reach glyphs of characters outside of the Type 1 chars table and I have no idea <strong>how to get the 'kern' and 'hmtx' tables from the font file? How to embed the glyphs?</strong></p> <p>I believe, I can do the kerning by the matrix transform PDF text directive: </p> <pre><code>[ (A) 120 (W) 120 (A) 95 (Y again) ] TJ </code></pre> <hr> <p><strong>UPD#1:</strong> MinionPro font have no 'kern' table. It have 'GPOS' (The Glyph Positioning Table) and I am pretty close to solving the problem. By the way, walking inside the binary file by PHP is nightmare((</p>

    1. COThis sounds like a lot of work. Why don't you use a OpenType-capable Unicode-aware TeX-engine like XeTeX or LuaTeX?

    2. COI LOVE LaTeX! I fell in love with Tex at first sight. Maybe, some day I will realize, that my current idea is total waste of time and I'll try to connect MySQL->PHP compiler->XeTeX(server?)->representation. But at the moment I have couple reasons to believe, that MySQL->PHP compiler->representation chain have some advantages for me. But who knows?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
