I just realized that this feature leads to a crash of the QtGui when the GIF is shown on Raspberry Pi 4. On my x86-machine this works without problem. I will ammend my pull request if I find a solution, if anybody can test this on a Raspberry Pi 3B, this would be great (I don't have one currently)

in raspi 3B generates the gif and displays it, but the gif occupies almost 40Mb

Thank you very much for checking this. Maybe the crash on my system just comes from the large filesize. It seems to me that Pillow creates a new color palette for every new image. Maybe this leads to the large file size. I will try to see if I can reduce the size.

good night, today I reinstalled and reconfigured the photobooth from 0 and now the images I get are 5 or 6 MB. I have observed that when selecting a style other than the default, the waiting time exceeds 1 second per pass (for example, if I put 10 Sec, it may take 15 seconds to take the photo). I have also noticed that when you start it, a raspi-webgui Wi-Fi network is generated that you didn't have before. When trying to access, he asks me for a username and password but I can't find this data anywhere. It would also be nice to add the option to put another gui button for boomerang.

As far as I see it, the raspi-webgui should not come from these changes as I have only touched the software itself. Typically the username and password are that of your system user.

good afternoon, I have updated the installation for your branch patkan-photobooth and the gifs are again too large and gives the raspberry general error. What is the difference between these 2 versions patkan-photobooth and Feature-boomerang-gif in the gif generation. This includes the overlay option and the sound that I have already implemented in my photo booth, but the boomerang does not work.
I would also like to know if it is possible to assign a gpio to launch the boomerang since right now I can only use it by adding a pointer to click on the option.

Thank you for your work and greetings.

Generally, if you want to see the difference between two branches, you can use a git diff. Github has a feature for this too: patkan/photobooth@feature-boomerang-gif...patkan:patkan-photobooth
patkan-photobooth is just the branch that I use to track the version of the software that I am using on my own photobooth.

That means also that you won't see newer changes on this branch than on the branch that is linked here. Unfortunately I did not have the time to continue my work on this, so it is still in the same state.

For the GPIOs, please check #44. This feature is not implemented yet. You would need to add a handler in the GPIO-module that generates the event on button-press.
