ManaAI is a free image processing application designed to prepare manga scans for optimum use on a portable eBook reader.

[edit] Features

  • Image processing:
    • Scale width/height (always maintains original aspect ratio)
    • Auto trim white space around a scan
    • Auto chop white rows and columns within a scan
    • Auto rotate scans to desired landscape/portrait orientation
    • Full color, grayscale, or grayscale color table
    • Specify # of colors
    • Change source image format
    • Add border after processing to fill specified width/height
    • Reduce to maximum dpi
  • Supported input sources:
    • Single folder of images
    • Single .zip/.cbz
    • Single .rar/.cbr (Note: Must have compatible unrar program installed on your system. See readme for details)
    • Single .pdf
    • A folder/archive containing any number of the above items, allowing you to process an entire manga series with one command.
  • Supported input image formats:
    • Pretty much anything that ImageMagick supports. It’s safe to assume that all major image formats are supported: .jpg, .bmp, .gif, .png, etc…
  • Supported output formats:
    • Folder of images (any image format supported by ImageMagick should be ok)
    • .zip/.CBZ
    • .rar/.CBR (Note: Must have compatible rar program installed on your system. See readme for details)
    • .PDF (including right-to-left page ordering)
    • .ePub (including right-to-left page ordering)
  • Binding:
    • Binding allows you to combine multiple input sources into a single output
    • Three ways to use binding:
      • Auto bind chapters into volumes based on interpreted volume-chapter info
      • Auto bind groups of a specified size
      • Create a bind file to manually specify which chapters to bind into a single volume
  • Auto split landscape 2-page scans:
    • Can detect whether a landscape scan contains two separate pages and split them accordingly
    • Tries not to split landscape 2-page scans where the two pages form one big image
    • Can also include the unsplit scan along with the two split pages
  • Volume-chapter interpretation (Manga Publication Model compliant):
    • Automatically interpret volume-chapter info for source folders
    • Bind chapters of the same volume (and create a fake volume binding for the latest chapters not yet released in tankobon)
    • Supports a large variety of source organization, including:
      • Nested folders/archives
      • Determine volume from parent hierarchy
      • Determine volume from observed bounds of a volume’s chapters
      • Detect special chapters and a/b chapters
      • Conflict resolution (both automatic and manual) when multiple sources map to the same volume-chapter
  • Volume-chapter-page scan interpretation (Manga Scan Model compliant)
    • Automatically interpret volume-chapter-page info for source scans
    • Sort scans by volume-chapter-page rather than filename string comparison
    • Detect special pages (front cover, insert, credits, etc.), string chapters/pages, lettered * chapters/pages, and more
  • Generate a settings file for a variety of ereader devices:
    • Optimal settings stored for many of the top ereader devices:
    • Can also generate a default settings file if MangAI doesn’t know the optimal settings for your particular ereader device
    • Any setting can be changed by the user to meet his/her needs
  • Multi-threading:
    • Mixed folder/image-level multi-threading, allowing you to process multiple folders and images in parallel
    • Automatically determines the number of threads to use based on detected cpu cores and workload (you can also manually specify the number of threads)
  • Other operations:
    • Organize
    • Organizes manga collection by interpreting volume-chapter info without processing images
    • Analyze manga collection
      • Returns statistics such as # of file types, # scans, file space usage, etc.
    • Analyze manga folder
      • Returns statistics such as width, height, and dpi of each image in the folder
    • Create MangAI batch file (available in the CLI only)
      • Creates a script to process your entire manga collection (i.e. all series) using MangAI
  • Job management (available in the GUI only):
    • Save a job so that you can run it again later (useful if you added new chapters to a series)
