I have the EZtwain Classic package from dosadi installed and scanning to memory 
and then writing from memory to file.  I can control the resolution and the 
pixel type (BW/GrayScale/Color) of the scan but can't control the brightness or 
contrast settings from my program.  The scan happens as requested without an 
error but the image does not change with the brightness and contrast values set 
by my program.  
 
When my code allows the built in user interface to be active, the brightness 
and contrast values set in that interface have the proper effect on the scanned 
image.
 
It would be helpful to know if anyone has been able to make this work.
 
Thanks in advance for any insight or advice,
 
Joe Yoder
