Hi.
In my books, I usually use a PNG image as a ebook cover, with transparent background, such as:
But, when I add it in Calibre, it appears with a cracked grey-white-black background in the Book details section:
In the E-Book Reader, it appears perfect, with a white background, as well as in a Sony PRS-600 and Adobe Digital Editions.
Is it a Calibre error? Will it be fixed? Or I'll have to change covers to jpg with white background?
Thanks!
