function RotateImage ).
The image should have the following properties:
Color scheme: Select one of the following
24 bit (True color)
256 Gray shades
Image size: Select one of t he following
3" x 5": This scan the full page of the passport
1" x 5": This scans only the lower portion of the page.
Once the function returns PASS_ERR_NONE , the library properties will be loaded with analyzed text.
Otherwise, the library property fields will be empty.
The raw data is scanned for format detection. If a specific format is detected, the data is parsed further
and load the library properties.
