Mangize - a better manga converter
Hello, I've been more of a lurker, but I would have loved to have a good manga manager for the Kindle. Decided I make my own, since Mangle wasn't offering a critical feature I wanted.
First version took me ~20 hours of programming (C++, Boost, CImg). New versions will be improvements, but they will be a little more farther apart since I have the functionality I wanted (and with that gone, so is the main drive behind my motivation ). Please add feedback (feature requests or bug reports/strange behavior). Latest version: v0.31 (26.3.2011) Current features: - Very fast thanks to C++ (converting 5 chapters (total of 130 images) takes ~4 minutes at maximum compression and quality on a single 2Ghz core) - Multi threading support (3 cores @ 3Ghz process 200 images at maximum compression and quality in a little over a minute ) - Low memory footprint (~30MB RAM max, depends on the number of threads) - Support for almost any device! - Removal of blank rows and columns - High quality dithering - High quality resampling - Further compression of images using pngcrush - Only jpg and png support for now, please comment if you want anything else (planing on adding gif and bmp later) - Automatic generation of bookkeeping files (for kindle) - Output settings (landscape/portrait mode, custom resolution) - Automatic conversion of color pictures to grayscale Latest version change log: (26.3.2011) v0.31 (see attachment) - resizing bug fix (didn't scale properly) - fixed program crash involving tightness setting (23.3.2011) v0.3 (see attachment) - added progress bar - updated user interface - exposed more settings to user, should make it compatible with a lot more devices now - added ability to save your settings - fixed landscape rotation bug (caused some images to be falsely rotated, reported by psycholoner) Change logs: Spoiler:
Todo: - gif, bmp support - requests? Program is around ~3MB and requires no external libraries (except for pngcrush, if you want to use it). Results (hope I'm not breaking any copyright with these pics): Example 1: Original Processed Example 2: Original Processed Dithering isn't very noticable in this example, but I have a few more and, at least to me, it looks better then Mangle, but it isn't really noticable on the device itself.

This looks pretty cool.
I just want to mention that a lesser known manga converter called Canti has almost all those features (although I'm not sure about the dithering and resizing method), auto splitting landscape 2-page scans except when the two pages form one giant image, trimming, auto cbz creation, colour quantization should be in the next release and much more. http://www.bitcake.com/?page=project_canti Edit: Just looked closer at the image and saw what you meant by removal of rows and columns, that's pretty awesome, Canti doesn't do that but it trims white space around the image. Edit: Now Canti does http://www.bitcake.com/?entry=entry110322-143300 Last edited by mobad; 03-22-2011 at 03:04 PM. |

Edited OP. Mangas processed by the program can be now cop/ pasted with no fiddling to the kindle.
Updated program (v0.2) is in OP attachments (also added pngcrush.exe to the zip) Edit: Updated attachment. Kindle didn't like a few things pngcrush did to the images. Compression is now down to ~10%. Will look into using gifs. Last edited by Honf; 03-18-2011 at 06:10 PM. |

Any chance of letting user specify output sizes? I know it's a planned feature, but really eager to convert to another resolution, as I read mainly in landscape format, ie 800x?
It's a surprisingly quick and small program. Really impressed with how well it runs even on a netbook. |

I'll have it done in ~24 hours (+ specifying the output folder).
I was reading some manga just now and I found landscape is much better on the eyes. Need sleep now. Last edited by Honf; 03-19-2011 at 07:09 AM. |

New version up (v0.22)
Added a few more settings that are use changeable. Didn't bug test too much, so tell me if program crashes or produces strange output. Edit2: Fixed a bug, added a sanity check for output directory (still same version, won't increment) |

I just ordered a 10in android tablet, mainly for reading digital manga, so I'll definitely be checking out this program.
And I just realized, this is only for Kindle, isn't it? |

I'm working on making it work for any device you want it too. As it is now you can use it just fine, but the images will be dithered to the Kindle 3/DX display, but that shouldn't be noticeable when compared with full gray scale images, due to the screen size.
Just to be sure, I'll put in a toggle to preserve full grayscale images in the next version then. Program should be updated by the time you get your tablet. |

I'm afraid I've given up on it. I tried to convert things and it was too much effort, the order of the images were all over the place (even ones numbered properly), as in totally random order - it takes hours to organise if there are a few hundred images.
Plus the save, open, etc options don't work - so if you want to redo the same project you have to start all over again. I'm using it under Ubuntu, so it may be an incomplete conversion, but no, takes waaay too much time. That said the image quality was quite good. It's a good idea, and if it were working - but as it is, waaaay too time consuming. |

I agree that if it's not ordered it useless. Could you try it out on a windows machine? |

Indeed a definitely better Manga converter Honf. Thanks.
But scans of full size comic books (larger than the typical Manga) are still too small to read comfortably on the Kindle3 screen. Have you considered something like https://launchpad.net/comicstrip to extract each frame of a page and create individual .pngs? Resizing then each frame to the Kindle screen size would much enhance readability. |

I guess I could put it in as an experimental feature in the future. It would work perfectly for "normal" manga panels. It's the occasional exotic arrangement of out-of-panel items that is hard to correct for. Last edited by Honf; 03-19-2011 at 10:44 AM. |

I wasn't running it wine, just running the pwf script. Never used wine - I'd give it a go, but I'm hunting up canti now instead.
