Docs For Class HTMLPurifier

Description

Class for converting between different unit-lengths as specified by CSS.

Located in /library/HTMLPurifier/UnitConverter.php (line 7)

Class Constant Summary

DIGITAL = 3

ENGLISH = 1

METRIC = 2

Variable Summary

static mixed $units

mixed $internalPrecision

mixed $outputPrecision

Method Summary

HTMLPurifier_UnitConverter __construct ([ $output_precision = 4], [ $internal_precision = 10], [ $force_no_bcmath = false])

void convert (HTMLPurifier_Length $length, string $to_unit)

int getSigFigs (string $n)

Variables

static mixed $units = array(
self::ENGLISH => array(
'px' => 3, // This is as per CSS 2.1 and Firefox. Your mileage may vary
'pt' => 4,
'pc' => 48,
'in' => 288,
self::METRIC => array('pt', '0.352777778', 'mm'),),self::METRIC=>array('mm'=>1,'cm'=>10,self::ENGLISH=>array('mm','2.83464567','pt'),),) (line 23)

Units information array.

Units information array. Units are grouped into measuring systems (English, Metric), and are assigned an integer representing the conversion factor between that unit and the smallest unit in the system. Numeric indexes are actually magical constants that encode conversion data from one system to the next, with a O(n^2) constraint on memory (this is generally not a problem, since the number of measuring systems is small.)
