  • Stitching and thumbnail processing executed immediately after capture. This creates a delay between capture time and the time it appears on the UI.
  • Stitching should be run parallel and UI updated as stitching is done.(FLUID-3545)
  • Currently stitching assumes a Book Liberator configuration, and rotates left and right images accordingly.
    • This means that if images are captured in a different orientation, then the stitched image will be rotated incorrectly.
    • If left and right pages are out of order, then the rotation may end up wrong resulting in upside down pages.
  • If source images are different sizes, then stitching will top-align the images when stitching. This results in white space around the smaller image.
  • Stitching process will create a greyscale stitched image, but leaving the original files unmodified.
  • Thumbnail generation is based on the greyscale stitched image.
