ps_set_text_pos

(PECL ps >= 1.1.0)

ps_set_text_posSets 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().


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);?>
