KEY TYPE OPI COMMENT VALUE
CropFixed array %ALDImageCropFixed (Optional) An array with the same form and
meaning as CropRect, but expressed in real
numbers instead of integers. Default value: the

Position array %ALDImagePosition (Required) An array of eight numbers of the
form
[ llx lly ulx uly urx ury lrx lry ]
specifying the location on the page of the
cropped image, where (llx , lly ) are the user space
coordinates of the lower-left corner, (ulx , uly ) are
those of the upper-left corner, (urx , ury ) are
those of the upper-right corner, and (lrx , lry ) are
those of the lower-right corner. The specified
coordinates must define a parallelogram; that is,
they must satisfy the conditions
ulx − llx = urx − lrx
and
uly − lly = ury − lry
The combination of Position and CropRect de-
termines the image’s scaling, rotation, reflection,
and skew.
Resolution array %ALDImageResolution (Optional) An array of two numbers of the form
[ horizRes vertRes ]
specifying the resolution of the image in samples
