TwainIsValidDIB

Checks whether a Device Independent Bitmap (DIB) handle contains valid image data.

Synopsis

flag = TwainIsValidDIB(Dib)

Args

Dib is the DIB returned by TwainCreateDIB.

Returns

A 1 if the DIB handle contains valid image data, or a 0 otherwise.

Notes

TwainIsValidDIB is useful if you need to know whether a DIB handle is safe to pass to other Twain DIB functions that require a DIB handle.

After calling TwainFreeDIB on a particular handle, TwainIsValidDIB will return a 0 for that handle.
