The repository, the Python package, the entrypoint and the manifest name all now agree. `plot` was carried over from the upstream opencv-plot node and no longer described anything here, so the module, the class and the environment variables follow the node: dora_plot/ -> dora_image_view/ dora_plot/plot.py -> dora_image_view/view.py Plot -> View PLOT_WIDTH/HEIGHT -> VIEW_WIDTH/HEIGHT --plot-width/-height -> --view-width/-height Breaking for anyone wiring `path: dora-plot` or setting PLOT_WIDTH; nothing is tagged yet.

# Node manifest: the typed contract a consumer wires against.

#
|
|
# No source package is shared between node repositories, so this file and its
|
|
# type URNs are the only contract a consumer has. `dora validate` checks a
|
|
# dataflow against it without running the node, so CI needs neither OpenCV nor
|
|
# a display.

type: std/core/v1/UInt8

required: false

description: >-
|
|
Base image to draw on: a flat UInt8 buffer described by the metadata
|
|
{width, height, encoding}. Supported encodings: bgr8, rgb8,
|
|
jpeg/jpg/jpe/bmp/webp/png (encoded bytes), yuv420, avif. Receiving this
|
|
input triggers a redraw and display.
|
|
bbox:
|
|
required: false
|
|
description: >-
|
|
Bounding boxes to overlay: an Arrow struct with fields {bbox, conf,
|
|
labels} and metadata {format}. Supported formats: xyxy, xywh. Stored and
|
|
drawn on the next image redraw. Deliberately untyped — senders differ in
|
|
whether the numeric fields are 32- or 64-bit, and the node casts either.
|
|
text:
|
|
type: std/core/v1/String
|
|
required: false
|
|
description: >-
|
|
Text string to overlay at the top-left corner. Stored and drawn on the
|
|
next image redraw.

description: Resize the displayed frame to this height (pixels). Defaults to the image input height.
