Normaly I'm using this :
$oQP.GetPageText($iExtractOptions)

to get Page Text.

But in some solutions I have PDF's with few ContentStream's / Layers

I know how to enumerate them, I use this functions:

Func _QPDF_GetOptionalContentGroupInformation(ByRef $oQP)
	Local $iContentGorupCount = $oQP.OptionalContentGroupCount()
	Local $aResult[$iContentGorupCount][4]
	For $iGroup_idx = 1 To $iContentGorupCount
		$aResult[$iGroup_idx - 1][0] = $oQP.GetOptionalContentGroupID($iGroup_idx)
		$aResult[$iGroup_idx - 1][1] = $oQP.GetOptionalContentGroupName($aResult[$iGroup_idx - 1][0])
		$aResult[$iGroup_idx - 1][2] = $oQP.GetOptionalContentGroupPrintable($aResult[$iGroup_idx - 1][0])
		$aResult[$iGroup_idx - 1][3] = $oQP.GetOptionalContentGroupVisible($aResult[$iGroup_idx - 1][0])
	Next
	Return SetExtended($iContentGorupCount, $aResult)
EndFunc   ;==>_QPDF_GetOptionalContentGroupInformation

My question is how I can get text only from specyfic Layer/ContentStream ?

Hi :)

perhaps this is the link you're looking for:

http://www.quickpdf.org/forum/how-to-preview-selected-content-stream_topic2305.html

BTW: You can't delete text from a selected contentstream/layer ... but you're able to select and delete a contentstream with the textcontent on it.

If you have a pdf with four layers i would make four copies.

In the copies i'll delete the first layer... in the second copy the second layer and so on.

Then i would start textextraction from the four copies.

Then i would compare the four textcontent.

Cheers and a nice weekend to you :)

Your advice sounds reasonable.

I will follow that path.

Thanks and have a nice weekend, ...... unfortunately, in our country, so far it is raining.

Cheers,
