In our application we need to check if a pdf contains text (vector).
We use the DAOpenFile and we use the function DAExtractText.

If the file is on a network folder, the function DAOpenFile could take 200ms.

Is there another faster way for checking if a pdf is vector or not ?

Hi Raphael!

Try...

// ... if (QP.HasFontResources < 1) Then ...

If the result < 1 then there is no text content.

So give it a try and forget your DA-function ;-)
