|---|---|
| Reference Point Color | Sets the color of the reference point (see Rotation and Position for more details) |

Variable
Every component has a unique variable name. This variable name can be used to reference the component in multi-state configurations and other scripts.
On creation, every component is given a default name. This can be overwritten to be more user-friendly. To do so simply overwrite the value in the variable input field.
Arrange / Remove

- Send Backward - move object one layer down
- Bring Forward - move object one layer up
- Send to Back - place object under all layers
- Bring to Front - place object above all layers
To send/bring objects to the front/back use the first four buttons. - Any set of components can be deleted by either using the

By default the reference anchor point is the top left corner. You can also rotate the component by dragging one of the yellow corner points.- You can set the position of the component by setting the
XandYcoordinates relative to theReference Anchor Pointand the top-left corner of the work area. - You can drag any of the anchor points to change the width and height of the component, or you can set it manually by editing the
WidthandHeightboxes. - Set
Lock Aspect Ratioso that while changing width and height, the component width to height ratio stays the same Transformallows you to view the component as a mirror or a reflection of itself

Behavior
- Files are bundled with the display β each upload is read and stored inside the view (as base64), so files travel with the view and need no external hosting. Downloads reconstruct the original file.
- Keep uploads modest β because files are embedded in the view, large files increase the display's size.

- PDF β embed a single uploaded PDF as a rendered document
- IFrame β embed externally hosted content instead of uploading
- Sharing Displays β how displays (and their bundled files) are shared
