UDF _ImageGetParam Improvement

Recommended Posts

wolfbartels

On JPG-files of some cameras there are both EXIF-Parameters "UserComments" and "Comment", causing the UDF _ImageGetParam() to become confused, because it searches only for Comment.

An easy solution is to include the inicial @LF and final "=" at $aParam when searching in $aData.

;===============================================================================
; Get param by name from function result
;===============================================================================
Func _ImageGetParam($sData, $sParam)
    Local $nParamPos = StringInStr(@LF & $sData,@LF & $sParam & "=") ; @LF and "=" added
    If $nParamPos Then
        $sData = StringTrimLeft($sData, $nParamPos + StringLen($sParam))
        Return StringLeft($sData, StringInStr($sData, @LF) - 1)
    Endif
    Return ""
EndFunc

Now the Func will always give a correct Return.

The function _ImageGetParam() is not part of the AutoIt distribution, so a BugTrac is not appropriate. The issue should be addressed in the topic that defines/supports that UDF.

Oh. Sorry I was thinking this was included with AutoIt, but I was mistaken. Kind of pointless not to post it in the thread about the UDF.
