ps_set_text_pos — Sets position for text output
说明
ps_set_text_pos (
resource
$psdoc ,
float $x ,
float $y ) :
bool
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().

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。

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);
