@Doitsu...
"There's a typo in the plugin description and the cover page warning. KindleGen doesn't support Cover html pages, but it does of course support embedded cover images. You might want to change the wording of the message."
I'm not really sure what you mean by "support embedded cover images". The reason I advise removal of the
cover.xhtml file from the epub was because both st_albert and Hitch advised me(further up on this thread) to add that warning. They should know because they are both professional formatters. The Amazon product image will automatically be added to the epub as the cover image file on KDP conversion. Remember also that this plugin only checks epub 2.0 files for upload to KDP. This plugin cannot check epubs formatted as KFX or epub 3.
Pillow supports dpi queries. Here's a snippet:
Code:
imgdata = bk.readfile(cover_id)
img = Image.open(BytesIO(imgdata)).convert('L')
xdpi, ydpi = img.info['dpi']
if (int(xdpi) or int(ydpi)) < 300:
print('dpi is less than 300.')
My thanks for your advice and for the above code. I searched high and low in the python docs and couldn't find anything on Pillow handling image resolution. I'll get that implemented in my next plugin update.
