Places a formerly loaded image at the current point on the page.
The image is scaled if x and
y have values unequal to 1.
The image data is ascii85 encoding which is only 20 percent larger
than the raw binary data of the image (The binary data is not equal to
the file size but somewhat smaller, because the file also contains an
image header.). You can turn on hex encoding by setting
the parameter imageencoding to hex. Hex encoding doubles the
size of the image data.
Since version 0.4.5 of pslib images are fully read and saved
into the output postscript file when they are opened with
PS_open_image_file(3). Later calls of
PS_place_image(3) just replay the image.
This behaviour can be turned off by setting the parameter imagereuse
to false with PS_set_parameter(3).
If image reuse is not turned of, this function may be called
within a template.
