__construct()

File: Buffer.php : 97
Description: Initialize fonts buffer
Signature: public __construct(float $kunit[, bool $subset = false][, bool $unicode = true][, bool $pdfa = false]) : string

Parameters:
  $kunit (float): Unit of measure conversion ratio.
  $subset (bool = false): If true embedd only a subset of the fonts (stores only the information related to the used characters); If false embedd full font; This option is valid only for TrueTypeUnicode fonts and it is disabled for PDF/A. If you want to enable users to modify the document, set this parameter to false. If you subset the font, the person who receives your PDF would need to have your same font in order to make changes to your PDF. The file size of the PDF would also be smaller because you are embedding only a subset. NOTE: This option is computational and memory intensive.
  $unicode (bool = true): True if we are in Unicode mode, False otherwhise.
  $pdfa (bool = false): True if we are in PDF/A mode.

Return values:
  string - Font key
