PHP TCPDF_STATIC::fileGetContents方法代码示例

 /**
  * Embedd a Scalable Vector Graphics (SVG) image.
  * NOTE: SVG standard is not yet fully implemented, use the setRasterizeVectorImages() method to enable/disable rasterization of vector images using ImageMagick library.
  * @param $file (string) Name of the SVG file or a '@' character followed by the SVG data string.
  * @param $x (float) Abscissa of the upper-left corner.
  * @param $y (float) Ordinate of the upper-left corner.
  * @param $w (float) Width of the image in the page. If not specified or equal to zero, it is automatically calculated.
  * @param $h (float) Height of the image in the page. If not specified or equal to zero, it is automatically calculated.
  * @param $link (mixed) URL or identifier returned by AddLink().
  * @param $align (string) Indicates the alignment of the pointer next to image insertion relative to image height. The value can be:<ul><li>T: top-right for LTR or top-left for RTL</li><li>M: middle-right for LTR or middle-left for RTL</li><li>B: bottom-right for LTR or bottom-left for RTL</li><li>N: next line</li></ul> If the alignment is an empty string, then the pointer will be restored on the starting SVG position.
  * @param $palign (string) Allows to center or align the image on the current line. Possible values are:<ul><li>L : left align</li><li>C : center</li><li>R : right align</li><li>'' : empty string : left for LTR or right for RTL</li></ul>
  * @param $border (mixed) Indicates if borders must be drawn around the cell. The value can be a number:<ul><li>0: no border (default)</li><li>1: frame</li></ul> or a string containing some or all of the following characters (in any order):<ul><li>L: left</li><li>T: top</li><li>R: right</li><li>B: bottom</li></ul> or an array of line styles for each border group - for example: array('LTRB' => array('width' => 2, 'cap' => 'butt', 'join' => 'miter', 'dash' => 0, 'color' => array(0, 0, 0)))
  * @param $fitonpage (boolean) if true the image is resized to not exceed page dimensions.
