Section 2. Image Layout

DG_IMAGE, DAT_IMAGELAYOUT, MSG_RESET => OK.
DG_IMAGE, DAT_IMAGELAYOUT, MSG_GETDEFAULT => ( 16232, -19996, 42,
-19996).
DG_IMAGE, DAT_IMAGELAYOUT, MSG_GET => ( 25328, -20168, 35, -20168).
DG_IMAGE, DAT_IMAGELAYOUT, MSG_SET (22166.4, -20168, 19004.8, -20168) =>
OK.
  Scanning to verify image layout: OK
    Returned image is 320 x 240 pixels, with resolution of 100 x 100 DPI
    Requested resolution was: 100 x 100 DPI
    Width  = 3.2 (versus requested -3161.62)
    Height = 2.4 (versus requested 0)

--- Compliance Summary ---

(0) ICAP_UNITS: MSG_GET value does not include TWUN_INCHES.
(1) ICAP_XFERMECH: MSG_GET after open, current value is not TWSX_NATIVE.
(2) ICAP_BRIGHTNESS minimum value not -1000.
(3) ICAP_BRIGHTNESS value does not include 0.
(4) ICAP_CONTRAST minimum value not -1000.
(5) ICAP_CONTRAST value does not include 0.
(6) ICAP_PIXELFLAVOR: MSG_GET after open, current value is not
TWPF_CHOCOLATE (relaxed in 1.9).
(7) ICAP_BITDEPTH contains value 24. A common error but technically
non-compliant.
(8) ICAP_BITDEPTHREDUCTION listed in CAP_SUPPORTEDCAPS but GET failed.
(9) ICAP_PLANARCHUNKY: MSG_RESET failed when it should succeed.
(10) ICAP_BITORDER: MSG_RESET failed when it should succeed.
(11) ICAP_BITDEPTHREDUCTION: MSG_RESET failed when it should succeed.
(12) Default ImageLayout upper-left coordinates not (0,0)
(13) Default ImageLayout has width or height of 0 or less!
