    <p>Does anyone have an easy way to calculate how many points across a page a piece of text will consume in a particular font and size? (easy = minimal lines of code + computationally cheap). Zend_Pdf doesn't appear to have a function that does this, except for some very expensive calls for each character to getGlyphForCharacter(), getUnitsPerEm() and getWidthsForGlyph(). </p> <p>I'm generating a multi page PDF with several tables on each page, and need to wrap the text within the columns. It's already taking a few seconds to create it, and I don't want it to take too much longer or I'll have to start messing around with background tasks or progress bars etc. </p> <p>The only solution I came up with is pre-computing the width (in points) of each character in each font size used, then adding these up over each string. Still quite costly.</p> <p>Am I missing something? Or have you got anything simpler? </p> <p>thanks!</p>

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.
