Closed kwcckw closed 1 year ago

kwcckw commented 1 year ago
  1. Improved the algorithm in PageBorder to create a better rotated page effect in different angles.
  2. Added function to rotate image with any angle in PIL.
  3. Fixed bugs in cache image loading function.

Some examples with the updated PageBorder:

Page border effect with random angle of stacked pages, and pages are loaded from cache (same page border = 0): image

Page border effect with random angle of stacked pages, and pages are loaded from cache (same page border = 1): image When same page border is True, their dimension and coordinates are matched with centroid.

Page border effect with large angle of rotations (-360, 360): image

Page border effect with random and small angle rotation: image

Page border effect with consistent and small angle rotation: image
