XYXY = 'XYXY'
class-attribute
[x0, y0, x1, y1], with x0,y0 = left,top and x1,y1 = right,bottom.

def log_rect(entity_path, rect, *, rect_format=RectFormat.XYWH, color=None, label=None, class_id=None, ext=None, timeless=False)
Log a 2D rectangle.
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
entity_path |
str
|
Path to the rectangle in the space hierarchy. |
required |
rect |
Optional[npt.ArrayLike]

RectFormat.XYWH
|
color |
Optional[Color]
|
Optional RGB or RGBA in sRGB gamma-space as either 0-1 floats or 0-255 integers, with separate alpha. |
None
|
label |
Optional[str]
|
Optional text to show inside the rectangle. |
None
|
class_id |
Optional[int]
|
Optional class id for the rectangle. The class id provides color and label if not specified explicitly. See rerun.log_annotation_context |
None
|
ext |
Optional[Dict[str, Any]]
|
Optional dictionary of extension components. See rerun.log_extension_components |
None

If true, the rect will be timeless (default: False). |
False

def log_rects(entity_path, rects, *, rect_format=RectFormat.XYWH, identifiers=None, colors=None, labels=None, class_ids=None, ext=None, timeless=False)
Log multiple 2D rectangles.
Logging again to the same entity_path will replace all the previous rectangles.
Colors should either be in 0-255 gamma space or in 0-1 linear space. Colors can be RGB or RGBA. You can supply no colors, one color, or one color per point in a Nx3 or Nx4 numpy array.
Supported dtypes for colors:
- uint8: color components should be in 0-255 sRGB gamma space, except for alpha which should be in 0-255 linear space.
- float32/float64: all color components should be in 0-1 linear space.
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
entity_path |
str
|
Path to the rectangles in the space hierarchy. |
required |
rects |
Optional[npt.ArrayLike]
|
Nx4 numpy array, where each row is [x, y, w, h], or some format you pick with the |
required |
rect_format |

identifiers |
Optional[Sequence[int]]
|

None
|
colors |

|
Optional per-rectangle gamma-space RGB or RGBA as 0-1 floats or 0-255 integers. |
None
|
labels |
Optional[Sequence[str]]
|
Optional per-rectangle text to show inside the rectangle. |

|
Optional dictionary of extension components. See rerun.log_extension_components |
None
|
timeless |
bool
|
If true, the rects will be timeless (default: False). |
