Good day!
Can I transfer in javascript image obtained by the method GetImage ()?
Is it possible in javascript to know the size of the image? Show it on the page?

Hello!
I am well acquainted with your examples and understand their essence.

Can I get a JS array of bytes which are image?
I do not know the languages of the VB and VBScript, but maybe they can get an image as a variable.
After all, the function GetImage returns VB object Picture.

You can get image as:
- IPicture (Image) using VSTwain.GetImage method
- HBITMAP using VSTwain.GetImageAsHBitmap method
- DIB (byte array) using VSTwain.GetImageAsDIB method
- Handle to DIB using VSTwain.GetImageAsHDIB method
- Three dimensional array of bytes using VSTwain.GetImageAsByteArray method

Best regards, Alexander
