signature widget

[G.W.Gaich]

Mike,

in one of my applications I use this code:

command saveSign
    show grc "UnterschriftRect"  -- lies behind the widget for a white 
background
    show widget "Unterschrift"

    lock screen
    if the pathData of widget "Unterschrift" is empty then exit to top
    thickenSignature "Unterschrift", 8  -- the signature is often too thin
    put 1200 into aMeta["density"]
    export snapshot from widget "Unterschrift" at size 140,70 with 
metadata aMeta["density"] to file "sign.png" as PNG

    hide grc "UnterschriftRect"
    hide widget "Unterschrift"

    unlock sceen
end saveSign

command thickenSignature pSignature,pFactor
    put the pathData of widget pSignature into tPathData
    repeat for each key tKey in tPathData
       multiply tPathData[tKey]["width"] by pFactor
    end repeat
    set the pathData of widget pSignature to tPathData
end thickenSignature

Hope this helps

Best regards
Günter
