Switch an image or layout if day or night (or by time) #

howing an image based on a condition is pretty simple, to switch between one image and another based on day/night status you can do the following:

Create an OverlapLayer that will contain both images
Add an Image object to the layer just created and pick the night image
Select the “Opacity” property and switch it to “formula” mode using the calculator icon
Click it and enter following code $if(ai(isday), 0, 100)$ this will set opacity to 0 during the day and to 100 in the night
Add another Image object to the layer and pick the day image
Switch Opacity to fomula as above and enter $if(ai(isday), 100, 0)$
Done!

This approach can be used also with text (using the color property) or with entire layers using a formula in the “visibility” property of the layer tab and returning either ALWAYS or NEVER.
