Change colour palette of an iPhone pic to use in a watch face

Former Member over 9 years ago

I'm making a watch face for my wife for our upcoming wedding anniversary, something nice with a picture of our kids as the background along with the data fields she likes to see on her vivoactive.

Everything is fine for the watch face code-wise, except that i can't seem to figure out how to convert the background image to something that looks good (the original looks crap in the simulator, understandably).

Here's the process:

1. Have photo taken with iPhone on my computer (jpeg).
2. Convert it to a vivoactive-friendly colour scheme.
3. Build the watch face, sneak it onto her watch.
4. Happy wife.

Can anyone suggest an easy way to do such a conversion? E.g. application, web service, command line, whatever. I use a Macbook pro but don't have any pic/photo editing software (the closest i have is Preview and iPhoto).

Thanks!

I've only done one watchface with a picture as a background for the vivoactive, and IIRC, all I did was use paintshop to cut the picture to the correct size and save it. I did find that having a very bright picture helped. On the sim, it does look much more grainy than on the actual watch. (it's MUCH better on the watch itself)

Here's how it looks in the sim:

Thanks. Here's an example of one pic i'm considering using ...

As an ordinary pic it looks great. Seems like i have some work to do :(

If you can try it on the actual va, it might look better, or at least point you at what to do to the picture.

Here's a screen shot of the actual .png I use, and info about that image from within paintshop:

and how the bitmap is define:

<bitmap id="id_pic" filename="images/pic.png" />

It looks like you have dithering disabled for that image. For that type of picture I think you will get better results with dithering enabled. As Jim said, the dithered image might look better on the device than it does in the simulator.

That seemed to do the trick! Thanks!
