Section 2. Image Layout 



DG_IMAGE, DAT_IMAGELAYOUT, MSG_RESET => OK. 

DG_IMAGE, DAT_IMAGELAYOUT, MSG_GETDEFAULT => ( 0, 0, 8.5, 11.69). 

DG_IMAGE, DAT_IMAGELAYOUT, MSG_GET => ( 0, 0, 8.5, 11.69). 

DG_IMAGE, DAT_IMAGELAYOUT, MSG_SET (1.06, 1.94, 2.12, 3.89) => Failed. 



--- Compliance Summary --- 



(0) CAP_XFERCOUNT: MSG_GET after open, current value is not -1. 

(1) ICAP_BITDEPTH contains value 24. A common error but technically non-compliant. 

(2) CAP_UICONTROLLABLE: MSG_RESET succeeded when it should not. 

(3) ICAP_PHYSICALHEIGHT: MSG_RESET succeeded when it should not. 

(4) ICAP_PHYSICALWIDTH: MSG_RESET succeeded when it should not. 

(5) CAP_ENABLEDSUIONLY: MSG_RESET succeeded when it should not. 

(6) CAP_DEVICEONLINE: MSG_RESET succeeded when it should not. 

(7) ICAP_XNATIVERESOLUTION: MSG_RESET succeeded when it should not. 

( ICAP_YNATIVERESOLUTION: MSG_RESET succeeded when it should not. 

(9) CAP_FEEDERLOADED: MSG_RESET succeeded when it should not. 

(10) DG_IMAGE, DAT_IMAGELAYOUT, MSG_SET (1.06, 1.94, 2.12, 3.89) failed although it is mandatory.
