Operators
↑ aktive op draw box-rounded on
Syntax: aktive op draw box-rounded on background ?(param value)...? [→ definition]
Returns an image where a box is drawn on the input image.
Beware, the location and size of the box are independent of image location and dimensions. The operator is perfectly fine computing the SDF of a box located completely outside of the image domain.
See also aktive image draw box-rounded and aktive image sdf box-rounded.
The box is axis-aligned, of width 2*ewidth+1, height 2*eheight+1, with rounded corners per the radii, and placed at the specified center.
The radii default to 0, i.e. no rounded corners.
| Input | Description |
|---|---|
| background | The image to draw on, i.e. the background for the drawing. |
| Parameter | Type | Default | Description |
|---|---|---|---|
| antialiased | bool | 1 | Draw with antialiasing for smoother contours (Default) |
| outlined | uint | 0 | Outline thickness. Draw filled if zero (Default). |
| color | str | List of band values, color of the drawn box. Their number has to match the input's depth. | |
| upleftradius | uint | 0 | Radius of element at upper left corner |
| uprightradius | uint | 0 | Radius of element at upper right corner |
| downleftradius | uint | 0 | Radius of element at lower left corner |
