[FEAT]: Limit the Viewport Movement

[Finestwork]

Mabuhay, contributors! 🌟

MySchemaFlow needs your assitance. Your task is to create a feature where user can enable a setting to restrict the viewport's movement. You can use this translateExtent property to set a boundary.

Tip:

• Calculate the total width and left position of each node
• Calculate the total height and top position of each node
• This will provide you with an idea of the minimum and maximum values for the translateExtent property.
• You can use Math.min and Math.max.

Happy Coding ~
