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);
?>
