Scanner Helpful Tips

Capturing Images

  1. Tap on the image to focus on an area.
  2. Tap on hold on an scanned image in the tray to drag and re-arrange.
  3. Scanner detects the orientation of the document and rotates it automatically.
  4. Good recognition results do not depend on document edges.
  5. When Auto Capture is turned on, the app will capture an image when the camera sees recognizable text and the device is held steadily for 2 seconds.
  6. If Edge Detection is enabled, ScanTone and Auto Capture both require all 4 edges be completely and clearly visible to activitate. So, if edges are not important to you, turn Edge Detection off.
  7. Only languages based on Latin alphabets are supported. For example, most Asian languages, Arabic, Russian and Greek are not supported.

Previewing Images

  1. On the image, double tap on a block of text to read it.
  2. In the text view, double tap on a word to starting read from there.

Saving and Exporting

  1. Exported PDF documents contain text layers and are accessible.
  2. We recommended using “Save to Files” option to save scanned PDF or text on your device, or in a cloud file system such as iCloud, Dropbox or Google Drive.
  3. After installing Voice Dream Reader 4.8.0 or newer, you will be able to scan documents directly from Reader.
