I have run an analysis with Spike’s Twister of this device.
— TW_IDENTITY block —
Product Name: HP Scanjet G4050 TWAIN
Product Family: All-in-One
Manufacturer: Hewlett-Packard
Software Version: 1.0 (“December, 2001”)
TWAIN Protocol Version: 1.9Here I noticed beside several other compliance issues a problem:
Section 2. Image Layout
DG_IMAGE, DAT_IMAGELAYOUT, MSG_RESET => OK.
DG_IMAGE, DAT_IMAGELAYOUT, MSG_GETDEFAULT => ( 0, 0, 8.57999, 12.32).
DG_IMAGE, DAT_IMAGELAYOUT, MSG_GET => ( 0, 0, 8.57666, 12.3167).
DG_IMAGE, DAT_IMAGELAYOUT, MSG_SET (1.07, 2.05, 2.14, 4.1) => OK.
Scanning to verify image layout: OK
Returned image is 858 x 1232 pixels, with resolution of 100 x 100 DPI
Requested resolution was: 100 x 100 DPI
Width = 8.58 (versus requested 1.07)
Height = 12.32 (versus requested 2.05)the problem that DAT_IMAGELAYOUT could not be set correct even it
returns ok.QUESTION: Is there any other way to set the area of interest or does it mean that this driver can only scan the full page if no UI is shown?
If there is interest I can upload the full report.
Best regards,
Kaij
