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().
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
。
