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:
    • Amazon: Kindle DX, Kindle 3, Kindle 2, Kindle 1
    • Apple: iPad
    • B&N: nook
    • Sony: prs-900, prs-700, prs-650, prs-600, prs-505, prs-500, prs-300
    • iRex: iliad, dr800, dr1000
    • Ectaco: jb, jbl
    • Kobo: kobo2, kobo1
  • 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)
