Hello,

I use the TImageEnMIO component in an Application for Multipage Scanning.

Is there a way to get the DPI information from the TIEBitmap in the OnAcquireBitmap event while scanning with TWainParams.VisibleDialog=true?

I tried several ways but I could not find a solution. I need the DPI information for following calculations.

Greetings,

Timo Michalska

Hello,
unfortunately no. DPI info (in TImageEnMIO.Params[].DPI) is filled just after the OnAcquireBitmap has been called.
Since next version it will be possible to read DPI inside OnAfterAcquireBitmap event.
