This article describes the class I2CE_FontMetricMultiDirection .

Class to contain information about font metrics. Setup to handle multiple directions.

Variables

$font_metrics

protecteed @var array of I2CE_FontMetric $font_metrics contains the fonr metrics that are global or for user defined directions

$direction

$directions

Methods

__construct()

The constructor @params array $directions of mixed the directions. the value -1 is reserved for global information array has a default value of 0 (horizontal) and 1 (vertical). Sets the direction to be $directions[0]

  • Defined in textlayout/lib/I2CE_FontMetricMultiDirection.php on line 39
  • Signature: public function __construct($directions,$encoding)
  • Parameters:
    • $directions
    • I2CE_Encoding $encoding
      the encoding used for the internal storage of strings/characters needs to be one that is a valid encoding for PHP multibyte strings.
