ps_set_text_pos (PECL) ps_set_text_pos -- Sets position for text output Descrizionebool 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().

- 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.
Valori restituiti
