To Acquire images from various sources (such as scanners, digital cameras, and others) first select the source in the Acquire dialog box.
The data source drivers list displays the Twain compatible drivers
available in the system. To select a source, simply click it.
The list is not updated automatically, so if you have installed a new image
acquisition device and it is not displayed in the list, click the Refresh
List button. Be also sure you refresh the list if you have uninstalled a
device driver.
You can also get the data source drivers list and select a source in the Select Source dialog box choosing the File > Select Source menu item.
When more than
one acquiring device is active i.e. you acquire an image (or images) from
another Twain data source having left the previous one open, you are prompted
with an error message about a software conflict. To avoid this, close a
currently opened dialog box or window first. Then close the Twain data source
window. Repeat acquiring again.
To acquire multiple images, check the Acquire multiple images box.
When checked, you can acquire multiple images from the same acquisition device
driver dialog box.
When cleared, the device driver dialog box is closed automatically once you have
acquired the image.
Make sure you close the
dialog box of the acquiring device driver after acquiring multiple images.
Note that some
acquiring devices do not support multiple images acquiring.
You can switch between an acquiring driver and our program. This is useful especially when you acquire multiple images.
