Can't see scanned image on QTWAIN

[debrasmith]

Hello guys,

I used the class Qtwain for scaned image. scans, the image is not shown.

What is this??

QPixmap::fromWinHBITMAP(), failed to get bitmap info ()

Any suggestions to solve this problem?

This is my code:

bool QTwain::save(QString dir)
{
return QPixmap::fromWinHBITMAP(m_hBitmap).toImage().save( dir,"jpg");

Hi, I guess something is wrong with m_hBitmap. How do you get that?

It sounds like you're encountering an issue with the bitmap handle. Can you confirm if m_hBitmap is valid and contains a valid image before you attempt to create the QPixmap?
