Dynamic Web TWAIN: Why do I only get a part of the image scanned?

Symptom:

When you acquire images, you may have only a part of the image been scanned.

Cause:

  1. The default page size that the source acquires is smaller than the actual page size of the image.
  2. You may use the SetImageLayout method to set which part of the image you are going to scan.

Resolution:

  1. Check the page size of the image. You can use the PageSize property to set the page size. For more information about this property, please click here.Also, you can bring up the User Interface (UI) of the source by setting the value of IfShowUI to true, and then set the page size in the UI before scanning.

  2. If you are using the SetImageLayout method, please check whether the parameters of this method are set properly. For more information about this method, please click here.
