Images with transparency look wrong in the dash

[Alejandro J. Cura]

How to reproduce:
- Go to the store scope
- Select the "Music & Audio" department
- Scroll to the bottom

What happens: the cards with overlays on top of images look wrong if the image has transparent areas. Please see attached screenshot.

Well now, I'd say any image with transparency should just never show up in the dash. Putting transparent images in the shape is something we should kill with fire, when this problem doesn't occur.

Perhaps this should be checked instead when devs are uploading apps. I'm adding the review scripts to this bug then.

But then again, there are apps already in the store with icons with transparency.
And I suspect any scope taking images from a 3rd party webservice will not be checking if said images have transparency or not, so I think the case of transparent images in the dash will be common.

Yeah, I know it's a little late.

I don't think it will be too common, actually. The only images on the
web I can imagine that have transparency are icons and logotypes.
There's few cases where this will happen, will be known beforehand, and
the plan to support this use case is to disable the shape altogether
(currently spec'ed to be a scope-wide customization option, still to be
implemented).

How would one check if images have transparency in a robust manner? Can't the image format be any number of formats (png, jpg, svg, etc)?

[Alejandro J. Cura (alecu)]

The check for transparency can be done with a library like ImageMagick.
Here's a small sample that checks for any transparent pixel in png, jpg, svg and gif: http://bazaar.launchpad.net/~alecu/+junk/detect-transparency/view/head:/check-transp.py

I'm going to mark this as "Won't Fix"-- this is really up to the uploader to make sure it looks correct on the device. That said, if someone wanted to provide an MP, I would review it.
