    Dear all,

    I am not able to set ICAP_FRAMES on my Avision AVA6 Plus device. It returns an pTW_ONEVALUE_FRAME on MSG/GET, but setting a scan area doesn’t work.

    Using the devices’ UI, I am able to set a scan area, though.

    What can I do now? Thank you for your help in advance!

    Twister Output:



    ICAP_FRAMES:
    GET………….frame Frame(0, 0, 4.15, 6.85)
    GETCURRENT……ditto
    GETDEFAULT……ditto

    Section 3. Image Layout

    DG_IMAGE, DAT_IMAGELAYOUT, MSG_RESET => OK.
    DG_IMAGE, DAT_IMAGELAYOUT, MSG_GETDEFAULT => ( 0, 0, 8.5, 11).
    DG_IMAGE, DAT_IMAGELAYOUT, MSG_GET => ( 0, 0, 8.5, 11).
    DG_IMAGE, DAT_IMAGELAYOUT, MSG_SET (0.7, 1.22, 7.38, 10.02) => Failed.

    Hi,

    You may try using CAP_SUPPORTEDCAPS to check if the capability ICAP_FRAMES is supported by the driver of your scanner.
