Hello everyone .
I write a software for the image manipulation connected to comics and ebook reader .
My software ( you can find it here , in the download section ) operate in this mode :
1st : Take the image , convert on BW and save it on 1024*768 format ( more than enough for the higher number of ebook reader ) . If the software catch a double page split it on 2 different image ( first the left if manga is not checked ) .
2nd : Crop the image to cut watermark or the classic white around the image .
Here you can take 2 different modus operandi .
You can convert the image in a PDF file ( the software autosplit the folder in this mode : If the image name initiate with VOL for every vol it make a PDF file or if the name star with CH. he make a PDF every 10 chapter ).
Same thing for CBZ .
I use the result everyday to read my manga on my iLiad .
The software is freeware so take it and tell me your opinion
Here a screenshot .
