Set scanning parameters Twain

Post by gtoledo » Fri Apr 29, 2016 7:58 pm

Hi,

I'm using version 10 of GdPicture and let me know if it is possible to establish by code, the scan parameters, ie: Color or B&W, 300 dpis, paper size: Letter.

best regards
I have a multipage file with several pages of different sizes and another file with a blank letter-size page. Attempt to merge with the multipage letter size page, someone can help me?

Hello

Yes, of course it is. In the GdPictureImaging class you will find methods with the name starting with Twain*.
The methods you are looking for are most probably TwainSetBitDepth, TwainSetResolution and TwainSetPaperSize.
Please refer to the corresponding documentation for more information as well as the other available methods.

Regards

Hi,

I appreciate your kind reply and let me tell you that your recommendation was successful, but only if set to "true" the method "TwainSetHideUI" otherwise does not work.
