[kamichi]

Hi Loïc , I have any questions about gdpicture .net.

First question:

I run metod TwainShowSetupDialogSource(). After that I see default twain window by my scanner. Everything good, but I see,
that which I have adjusted my profiles in the previous session have got off.

Why they have changed I changed of nothing.
In my profile was:

And In my profile became:

Compression JPEG has changed on NONE. Metod TwainSetCompression() in my code don’t run.

Second question:

If we run scanner setup window by metod TwainShowSetupDialogSource.
Whether there is a possibility to learn that the button ….ок.cancel etc. has been pressed

Hi,

This problem is not related to GdPicture.NET but to your TWAIN driver which does not make your configuration persistent.

A workaround consists to save & reload your modified configuration through the TwainSaveConfiguration & TwantLoadConfiguration method.

Hope this helps !

Hi,

Thank you, Loïc I'd like to clarify why it's the driver's fault. If I set compression via TWAIN driver configuration dialog, save settings, close and open the dialog again, the settings are loaded correctly. Compression is turned on. The problem happens only if config dialog box is open through GdPicture.NET. If displays that configuration has been changed at very beginning without any my action. Could you provide more details why compression is shown changed?
Scanner model is Kodak ScanMate i1120 Scanner.
