IMAGEPSBBOX(3)								 1							    IMAGEPSBBOX(3)

imagepsbbox - Give the bounding box of a text rectangle using PostScript Type1 fonts

SYNOPSIS

       array imagepsbbox (string  $text, resource  $font, int  $size)

DESCRIPTION

       array imagepsbbox (string  $text, resource  $font, int  $size, int  $space, int	$tightness, float  $angle)

	Gives the bounding box of a text rectangle using PostScript Type1 fonts.

	The  bounding  box  is	calculated using information available from character metrics, and unfortunately tends to differ slightly from the
       results achieved by actually rasterizing the text. If the angle is 0 degrees, you can expect the text to need 1 pixel more to every  direc-
       tion.

PARAMETERS

	      o $text
		- The text to be written.

	      o $font_index
		- A font resource, returned by imagepsloadfont(3).

	      o $size
		-$size is expressed in pixels.

	      o $space
		-  Allows you to change the default value of a space in a font. This amount is added to the normal value and can also be negative.
		Expressed in character space units, where 1 unit is 1/1000th of an em-square.

	      o $tightness
		-$tightness allows you to control the amount of white space between characters. This amount is added to the normal character width
		and can also be negative. Expressed in character space units, where 1 unit is 1/1000th of an em-square.

	      o $angle
		-$angle is in degrees.

RETURN VALUES

	Returns an array containing the following elements:

       +--+--------------------+
       |0 |		       |
       |  |		       |

       |  |		       |

IMAGEPSENCODEFONT(3)							 1						      IMAGEPSENCODEFONT(3)

imagepsencodefont - Change the character encoding vector of a font

SYNOPSIS

       bool imagepsencodefont (resource  $font_index, string  $encodingfile)

DESCRIPTION

	Loads a character encoding vector from a file and changes the fonts encoding vector to it. As a PostScript fonts default vector lacks most
       of the character positions above 127, you'll definitely want to change this if you use a language other than English.

	If you find yourself using this function all the time, a much better way to define the encoding is to set ps.default_encoding in the  con-
       figuration file to point to the right encoding file and all fonts you load will automatically have the right encoding.

PARAMETERS

	      o $font_index
		- A font resource, returned by imagepsloadfont(3).

	      o $encodingfile
		-  The	exact format of this file is described in T1libs documentation. T1lib comes with two ready-to-use files, IsoLatin1.enc and
		IsoLatin2.enc.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      imagepsencodefont(3) example

	      <?php
	      // Load a .pfb font file
	      $font = imagepsloadfont('./px3l.pfb');

	      // Tell T1lib to use ISO Latin 1 encoding
	      imagepsencode($font, './IsoLatin1.enc');

	      // Do any operations with the font here

	      // Free the font from memory
	      imagepsfreefont($font);
	      ?>
