App Behaviour

Scale To Fit

When an item is targeted (centered), the photo size is determined by these variables:

• constraint:

  Maximum constraint applied to each item width and height

• fitRatio:

  Fit ratio applied to a center front item

• scaleToFit:

  Control the item scaling behaviour when it is brought to center front. Possible value: “always”, “none”, “smart”.

Note

All items are firstly constrainted to a maximum width and height specified by constraint variable. The app will then try a best fit scaling applied to the targeted item so its dimension will match the app dimension. fitRatio will then be applied, usually it will scale down the targeted item, revealing other user interface.

scaleToFit will affect the app scaling behaviour: “none” completely disables scaling when item keeps its constraints width/height. “always” applies scaling everytime. “smart” only applies scaling if the item dimension is larger than app dimension.
