    int $imageid,
    float $x,
    float $y,
    float $scale
): bool

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().

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
