Set parameters on download metadata to only search for large covers

FacetiousKnave · 12-05-2022, 05:42 PM

When I use the function Edit Metadata > Download Metadata and Covers, Calibre normally finds the right covers, although their size and resolution are quite random. More often than not the quality of the covers is very poor.

I have installed the Goodreads plug-in in order to increase the chances of finding a good size and good quality cover, but the final result differ little.

Is there any way to set some parameters so that Calibre only search for large cover images?

Thanks.

I haven't tried it myself, but I remember there's an option in Barnes & Noble plugin, that allows scanning a wider range of editions, thus potentially increasing the likelihood of getting a large cover image:

Search the Internet Plugin also has a size option for Images

Thank you both. I'm giving both plugins a try.

Ok, just to leave a record that the Search the Internet plugin does the work. I just needed to modify the Google Images URL so it only searches for "large" images:

Kindle (Amazon) High-res Covers plugin is helpful too.

I find the Kobo store metadata plugin also tends to find large covers.

Unfortunately, that's because the images are resized to the maximum cover size in the maximum_cover_size (set it to 1800x2700 and your images will all show up as 1800xYYYY or YYYYx2700, whichever dimension reaches the limit first).

Thanks, I just installed the plugin and it works very well.
