Here are some docs from the PHP Functions Essential Reference (http://php-er.com) until the doc team gets a chance to update the manual. I would have just sent you to the site, but I have not yet gotten the html version of the book online yet. :o) double pdf_get_value ( resource pdf, string key, [double modifier] ); Returns the setting of value for key Gets the current setting of a value in the PDF document. This could be a default value or a value set using pdf_set_value(). Only a subset of the values able to be set with pdf_set_value() can be retrieved using this function. These are: - leading - textrise - horizscaling - textrendering - charspacing - wordspacing New values that can be accessed are: font Identifier of the current font set with pdf_setfont() fontsize Current size of the font set with pdf_setfont(). capheight Height of a capital letter of the loaded font ascender Height of a letter of the loaded front from the baseline to the top of the letter descender Height of the descending portion of a font from the baseline to the bottom of a font. For example, the distance from the baseline to the bottom of the letter 'p' textx X coordinates of the current text position texty Y coordinates of the current text position currentx X coordinates of the current point currenty Y coordinates of the current point imagewidth Width in pixels of the currently loaded image imageheight Height in pixels of the currently loaded image resx Horizontal resolution of the currently loaded image resy Vertical resolution of the currently loaded image Since version 4.0.1 Example 1.37.
