PHP TCPDF_FONTS::UTF8ArrayToUniArray方法代码示例

 /**
  * This method prints text from the current position.<br />
  * @param $h (float) Line height
  * @param $txt (string) String to print
  * @param $link (mixed) URL or identifier returned by AddLink()
  * @param $fill (boolean) Indicates if the cell background must be painted (true) or transparent (false).
  * @param $align (string) Allows to center or align the text. Possible values are:<ul><li>L or empty string: left align (default value)</li><li>C: center</li><li>R: right align</li><li>J: justify</li></ul>
  * @param $ln (boolean) if true set cursor at the bottom of the line, otherwise set cursor at the top of the line.
  * @param $stretch (int) font stretch mode: <ul><li>0 = disabled</li><li>1 = horizontal scaling only if text is larger than cell width</li><li>2 = forced horizontal scaling to fit cell width</li><li>3 = character spacing only if text is larger than cell width</li><li>4 = forced character spacing to fit cell width</li></ul> General font stretching and scaling values will be preserved when possible.
  * @param $firstline (boolean) if true prints only the first line and return the remaining string.
  * @param $firstblock (boolean) if true the string is the starting of a line.
  * @param $maxh (float) maximum height. It should be >= $h and less then remaining space to the bottom of the page, or 0 for disable this feature.
  * @param $wadj (float) first line width will be reduced by this amount (used in HTML mode).
  * @param $margin (array) margin array of the parent container
  * @return mixed Return the number of cells or the remaining string if $firstline = true.
  * @public
  * @since 1.5
