说明

bool ps_place_image ( resource $psdoc , int $imageid , float $x , float $y , float $scale )

Places a formerly loaded image on the page. The image can be scaled. If the image shall be rotated as well, you will have to rotate the coordinate system before with ps_rotate().

参数

psdoc: Resource identifier of the postscript file as returned by ps_new().
imageid: The resource identifier of the image as returned by ps_open_image() or ps_open_image_file().
x: x-coordinate of the lower left corner of the image.
y: y-coordinate of the lower left corner of the image.
scale: The scaling factor for the image. A scale of 1.0 will result in a resolution of 72 dpi, because each pixel is equivalent to 1 point.

返回值

如果成功则返回 TRUE，失败则返回 FALSE。
