CompressedImage
A compressed image.
Panel support
CompressedImage is used in the 3D and Image panels.
Schema
| Field | Type | Description |
|---|---|---|
timestamp | time | Timestamp of the image. |
frame_id | string | Frame of reference for the image. The origin of the frame is the optical center of the camera. +X points right in the image, +Y points down, +Z points into the plane. |
data | bytes | Compressed image data. |
format | string | Image format. Supported values: jpeg, png, webp, avif. |
Note: A new ROS image format string will be accepted but not parsed or decoded by the viewer. Only the standard formats (
jpeg,png,webp,avif) will be recognized and decoded natively.
Other format strings will rely on JavaScript's Blob MIME type parsing, which does not support the ROS-specific format strings..
Reference implementations

| ROS 2 | foxglove_msgs/msg/CompressedImage |
| JSON | foxglove.CompressedImage |
| Protobuf | foxglove.CompressedImage |
| FlatBuffers | foxglove.CompressedImage |
| OMG IDL | foxglove::CompressedImage |
