Input Image File

2 VersionsInput

Decodes images from the bound directory and emits each as a BGR Image at a paced rate, optionally resizing and looping. Use it for offline batches or deterministic image test sets.

How it fits

Typical backends

Object-detection batch over a folder of images, reported as JSON.

OCR batch — read text from each image and emit it as JSON.

Caveats

FallbackThe bound slot is a directory; files that fail to decode are logged and skipped rather than aborting the run.
I/O contractThe emitted Image is in BGR channel order, so consumers that need RGB must convert.
Parameter interactionwidth and height left at the sentinel keep the source dimension on that axis, and setting either triggers a resize that does not preserve aspect ratio on its own.
Hard constraintfps paces emission against a wall clock, so a non-positive rate stalls the component.
State lifetimerepeat loops the directory when on and stops after the last file when off; width, height, repeat, and fps are hot-swappable, and changing the bound slot restarts from the new directory.
