ps_set_text_pos
(PECL ps:1.1.0-1.3.5)
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
如果成功则返回 TRUE，失败则返回 FALSE。
