Picture overlay template

[Exiasets]

Hi @swieprecht , when you start pibooth for the first time, the configuration file is generated with all the default keys. It should be exactly like that: https://pibooth.readthedocs.io/en/latest/sources/config/config.html#default-configuration

Just before the section [CAMERA], there is the key overlays. Whatever your overlay (a .PNG image file) is, just put the path to the file.

The overlay is automatically resized to fit the pictures size keeping same ratio. So your overlay shall have same ratio whatever the size.

If you want 2 different overlay, for 1 and 4 captures, you have to provide a list of quoted path (see documentation)

Following up on an image overlay, are we supposed to scale the back ground overlay with a transparent section for the photo? I also tried adding the pibooth-picture-template, but I can not get the overlay image to work on one of the templates. Also how can we select which template is used?

I am new to using raspberry pi.
