This was posted to Facebook today by the creators of SwankoLab. The note details an issue where SwankoLab outputs blank prints under certain conditions, and it gives a workaround until an update which addresses the issue is released.

We’ve received a couple of bug reports from users who are getting blank images out of their SwankoLab, and thanks to a few helpful users (thanks Mark and Nick!) we’ve been able to isolate what is causing this bug.

The bug happens when you process an image other than a JPG (specifically we’ve been able to get the bug to happen when processing PNGs). While most apps on the iPhone (including the native camera app) use JPG images, there are some effects apps that will convert your image into a different format, and this is where we think users are running into problems.

Either way, this is a bug on our end and we’re hard at work getting a fix for it into the next SwankoLab update. Note that this will not be fixed in the 1.0.1 version which is currently in review at the App Store (since we submitted that build before we were able to isolate the cause of this bug). It will be fixed in our next update, though.

In the meantime, the workaround for this is to either process your prints in High Quality mode (which you can enable in the Settings app on your home screen), or to convert your image to a JPG before running it through SwankoLab. Sorry for the inconvenience, and we’ll get a fix out as soon as we can!
