Hello,

I use LEAD Document Imaging 13.

When I look into a scanner program, there is an option to set background color.

So, I try to find an option to set backgrount color.

But, I can't find any option in LEAD Twain API Help File.

Please tell me how to set background color.

Thank you!!

Is this a
Twain scanning function, or is it processing for the image after it is scanned?
I don't think the Twain standard defines such a feature, so if it is a scanner feature, it might be a custom feature.


Can you give me more details about how you use it?

Hi, Thank you for your reply.

I attached two images of twain driver scanner option dialog .

When you extract an attached file, you can see "default option" image and "detail option" image.

Default option dialog will be set as using LTWAINPROPERTIES struct.

But I can't find any struct to set background color of scan image like detail option dialog.

When background color is not set to black or white, color scan image is not to no effect about L_AutoTrimBitmap function.

Thank you

Bash,
Try using the ICAP_AUTOMATICBORDERDETECTION capability. Please note that ICAP_UNDEFINEDIMAGESIZE should be enabled to use this feature.
