说明

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.
