ps_set_text_pos

(PECL ps >= 1.1.0)

ps_set_text_pos — Sets position for text output

说明

bool ps_set_text_pos ( resource $psdoc , float $x , float $y )

Set the position for the next text output. You may alternatively set the x and y value separately by calling ps_set_value() and choosing textx respectively texty as the value name.

If you want to output text at a certain position it is more convenient to use ps_show_xy() instead of setting the text position and calling ps_show() .

参数

psdoc: Resource identifier of the postscript file as returned by ps_new() .
x: x-coordinate of the new text position.
y: y-coordinate of the new text position.

返回值

成功时返回 TRUE ，或者在失败时返回 FALSE 。

范例

Example #1 Placing text at a given position

  <?php
$ps  =  ps_new ();
if (! ps_open_file ( $ps ,  "text.ps" )) {
  print  "Cannot open PostScript file\n" ;
  exit;
}

 ps_set_info ( $ps ,  "Creator" ,  "rectangle.php" );
 ps_set_info ( $ps ,  "Author" ,  "Uwe Steinmann" );
 ps_set_info ( $ps ,  "Title" ,  "Text placement example" );

 ps_begin_page ( $ps ,  596 ,  842 );
 $psfont  =  ps_findfont ( $ps ,  "Helvetica" ,  "" ,  0 );
 ps_setfont ( $ps ,  $psfont ,  8.0 );
 ps_show_xy ( $ps ,  "Some text at (100, 100)" ,  100 ,  100 );

 ps_set_value ( $ps ,  "textx" ,  100 );
 ps_set_value ( $ps ,  "texty" ,  120 );
 ps_show ( $ps ,  "Some text at (100, 120)" );
 ps_end_page ( $ps );

 ps_delete ( $ps );
 ?>
