Struct ViewportVector

Namespace

FlowGraph.Core.Coordinates

Assembly

FlowGraph.Core.dll

A vector/delta in viewport coordinate space.

Viewport vectors represent movements and distances in screen/control space. They are affected by zoom - the same canvas distance appears as a larger viewport distance at higher zoom levels.
