ImSequencer, How to snap CurvePoint to the Sequencer Frames #189

Open smbss1 opened 3 years ago

Hello! First thank you for ImSequencer and ImGuizmo, they are really useful.

My question is like the title says, I'm working in a sort of Animation Keyframe Editor and I use RampEdit Class Sample to have a keyframe inside Sequence Item. The problem is I want to snap the points(keyframes) to the grid draw by ImSequencer::Sequence.

How I can get the pixel position of the frames ?

Here is the line of code that computes the X coordinate for a particular frame:
