Re: [Gtkpod-devel] Sparse Artwork Support

[Rod H. <iwa...@go...>]

Just a quick update on my testing. Well, the size of the artwork DB is 
now MUCH better! Coverflow is responsive again, and for a ~50Gb 
collection, I only have ~165Mb of artwork stored. This is great!

I also now have noticed some thumbnails with an extended bottom pixel 
line like you pointed out, Jorg now that I've managed to upload my 
entire collection.

I'm pretty sure that it only happens on those images that have a greater 
horizontal resolution than that of the vertical. The image is placed at 
the top of the square "frame" then a pixel line repeated as necessary 
until it reaches the bottom of the square space to be occupied.

It looks like that the amount of image that is taken up by this repeated 
pixel line is proportional to the percentage of the image that is wider 
than it is high (if that makes sense!).

For instance, I had one bit of artwork that was very narrow compared to 
its height (akin to a 2.35:1 letterboxed movie), and sure enough the 
image started at the top and then a pixel line extended almost from the 
half-way mark right down to the bottom. Unfortunately, I think I've 
replaced any artwork that was affected, so I may not be able to find 
more examples...

However, it doesn't seem to happen on ALL images whose horizontal is 
larger than its vertical - some will look complete and in the correct 
ratio, but have the bottom "space" filled with white instead of a repeat 
of a bottom pixel line. Perhaps it depends to what degree the images' 
dimensions differ?

Filling with white is a good trade-off IMO - it used to be black from 
what I can remember, and that looked very odd against the iPod's white 
Now Playing and Coverflow backgrounds...
