The Voynich manuscript published by Yale UniversityScan imageBecause it was huge 4 MB per piece, Terence Eden made e-books, image manipulation software ImageMagick's "Mogrify"I tried to downsize it to a size that makes it easy to manage the image using the command" However, there are also images with multiple pages in a row, and it seems that the size of the image was uneven one by one.


If you resize the image as it is, it will be too small, so we checked the size of the image using ImageMagick's "identify" command and found that the vertical length of the image is up to 6000 pixels and 1352 pixels minimum. In order to convert it into an electronic book, it is enough that the long side is about 1280 pixels, so it seems that the vertical width of the image was resized to 1280 pixels at a time. After resizing, the size of the whole image was reduced to 59 MB, but there are images showing extra things such as the edge of the next page, so check the images one by one and trim them manually It was said that.

Also, since many illustrations are drawn in the Voynich manuscript, the file types of e-books are created in ". Pdf" format instead of ".mobi" or ".epub".

When uploading the created PDF file to Amazon's Kindle store, due to the specifications of Amazon, it happens that all the pages are divided into true half.


there,Kindle Comic CreatorWhen I used it, I was told that one page was successfully displayed this time. However, as of 2013, there was a limitation that "the file size that can be uploaded to the Kindle store is limited to 50 MB maximum", so Eden would have to reduce the vertical width of the image to 1000 pixels inevitably and keep it at the maximum limit of 49 MB It seems that he succeeded.


In addition, at the time of article creation, the e-book of the Voynich manuscript created by Eden has been deleted from the Kindle store, but PDF files uploaded to Dropbox can be downloaded for free.
