Drawing a Drag Path




What is a drag path?

The Drag path is the most important feature of DRAGRI.

Dragging the mouse along the drag path drawn on an image enables you to move an object as if you are holding it.

Drawing a drag path is very easy.

Specify the starting point (IN Point) and the end point (OUT Point) of the movement of an object, and drag along the movement path with the mouse to draw a line.

STEP 1

Make this frame the starting point (IN Point).

STEP 2

Make the point where a girl's hand is raised to the highest point the end point (OUT Point).

STEP 3

Drag along the line of the movement of the hand to draw a drag path.

These are the basic steps for drawing a drag path.




Setting IN Point and OUT Point

A drag path is created to follow the movement of an object in a video. You need to specify the frames which mark the starting point (IN Point) and the end point (OUT Point) of the drag path, and then draw a drag path along the movement path for the object.

Using the IN Point button and OUT Point button on the Tool bar.

Select the frame you wish to make the IN Point by moving the current frame marker (the double red vertical lines) to the desired position and then clicking the IN button ( ) on the Tool bar.

The IN Point marker (the left-hand semicircular marker at the top of the timeline), moves to the current frame.

In a similar manner, move the current frame marker and, press the OUT Point ().

Moving the IN Point and OUT Point Markers on the timeline.

You can drag the IN Point Marker and OUT Point Marker to where you wish to place them on the timeline.




Drawing a drag path

Next, set a drag path along the line of movement for the object in a video. First, put the IN Point and the Out Point to the proper positions (frames). A drag path is drawn between the two frames. There are four ways to draw a drag path, as follows:

Drawing a free curve


Click the Free Curve tool on the tool bar and draw a free curve with the mouse. The path of the movement of the cursor becomes the drag path.

Rhombus


Click the Rhombus tool and draw a rhomboid path.

Vertical path


Click the Vertical tool and draw an exact vertical path.

Horizontal path


Click the Horizontal tool and draw an exact horizontal path.



The state after a drag path is drawn

Main window display

A drawn drag path is displayed. If you use Play mode () and drag the mouse on the canvas, you can check the movement.

In Edit mode (), you can still confirm the movement in a similar manner by dragging slightly away from the drag path. (Note that dragging the drag path with the mouse changes the shape of the path.) When a drag path is drawn, the image or video objects in the lower layers are automatically locked so that they cannot be moved.

Time line display

- Drag path (blue square and red line)
The inserted drag path is displayed as a red line on a layer.The inserted drag path is displayed as a red line on a layer.
A blue square indicates the frame position for each handle. When you drag this blue square, you can change the frame that corresponds to the handle.
- Layer name
The layer name is displayed. To change the layer name, click the layer name to display the corresponding information palette, and change the name in the information palette.
- Effective section
When a drag path is inserted, the effective section for the drag path is set to the entire content by default.
For details, see "Setting the Effective Section for a Drag Path."

Information palette display

- Path name
This indicates the name of a drag path. If you wish to change the name, click the name and enter a new name from the keyboard.
- Position (x, y)
This indicates the position of a drag path using coordinates.
- Size (w, h)
This indicates the size of a drag path in terms of the number of pixels.
For other details which can be set, see "Setting Details of a Drag Path."



Deleting a drag path

To delete a drag path, click on the drag path in the main window or specify a layer in the timeline window to select the drag path in the Edit mode ().

Select [Edit]-[Delete] from the menu bar or press the [Delete] key.
