wrong png format

[SimoneCarnio]

When uploading files in iTunesConnect i receive this error:

Images can’t contain alpha channels or transparencies.

I've "resolved" the issue by introducing (imageAlpha) https://github.com/ramiroaraujo/alfred-image-optim-workflow in my script after calling "snapshot".

If you have a better solution to integrate please let me know

Thanks for reporting.

Yes, it seems like there is a problem with manually uploading the screenshots.

Have you tried uploading your screenshots using Deliver?

It shouldn't be difficult to remove the transparency from a png using imagemagick. The problem is: Snapshot currently does not require imagemagick which makes the install process much simpler.

I'll take a look at it! In the meantime, just use Deliver to upload your screenshots.

I didn't try Deliver yet, it's in my roadmap for the weekend. I totally agree with your consideration, better to keep it simple. Eventually if the problem persist, write a note in the readme for future users ;)

Using imagemagick, it would be really easy. I know, it's a pain to set up for some users. I'll try to find a good solution, which does not require this system dependency.

Another solution could be to just check if it's installed, if yes, it will remove the alpha channel, if not, a note is displayed, that this has to be done.

I just tried, it works perfectly uploading the generated screenshots using deliver. I'll take a look at removing the alpha channel now.

It's fixed: 9cf5e4f

If imagemagick is installed, it will be used. If not, it will only show a warning, that the alpha channel couldn't be removed.
