Please don't downscale or convert my images, ebook-convert !
Hi Mobile Read community !
As mentioned before here on this forum, I'm trying to convert an CBZ file containing a serie of jpg file into an EPUB... and to be Amazon compliant... to distribute my first comic. But... ! Amazon now recommend large HD image files (see p.53) and a 1920x1200 definition is a minimum... for now I have 1020x1447 px images (to be upgraded if needed), and I just what them to be kept as they are. And converting to an epub command line, I can't find a way to stop calibre down-scaling them to 531x754, and converting them to png which result in smaller images and increased kilobytes ! here is the command line I use : Code:
ebook-convert $joinedfilename.cbz $joinedfilename.epub --authors "$creator" --publisher "$creator" --title "$title" --isbn "$ebookIsbn" --pubdate "$pubDate" --no-default-epub-cover --dont-grayscale --dont-normalize --keep-aspect-ratio --comic-image-size "1020x1447" --disable-trim --dont-add-comic-pages-to-toc --wide Code:
Rescaling image from 1020x1447 to 531x754 0_0.png Any idea ? Is there another command line option ? should I use another input format ? Thanks in advance ! |
