Click on any of the Quick Character Library icons to open a Character Grid.  As you move the mouse over a character icon (headshot), the preview window will display a full image of the character. Select a character.

The pre-drawn characters are in different actions (standing, sitting, running, jumping, prone) and various rotations making them ready for immediate use. Once you've decided on the character's action and rotation, click on the image in the grid and the image you chose will appear in the frame.

Vertically: a character is available in five pre-drawn actions.

• Walking
• Sitting
• Running
• Jumping
• Prone

Horizontally: each action is in the following rotations:

• face front
• quarter right
• profile right
• back
• profile left
• quarter left

The selected character zooms closer or pushes farther back when clicking the plus or minus in the toolbar. [Select the character in the frame, and click on "+" or "-" icon.]
Unused portions of the image are masked behind frame's edge (see above) which simulates a camera viewfinder.
No need to crop or erase parts of images to fit into frame's aspect size. If you change the aspect ratio of the entire project, the entire elements is ready to be seen in the new ratio setting.
Duplicate frame frunction copies all elements into a new frame window and since you didn't have to erase parts of images to conform to frame window, the image is still whole and ready to be resized for the next set up
