spacr.image_colors

Colour-order boundaries for OpenCV.

spaCR’s in-memory colour contract is RGB (or RGBA). OpenCV is the one major dependency that decodes and encodes three-channel images as BGR, so conversions belong directly beside imread/imwrite rather than in plotting or model code. Grayscale arrays pass through unchanged.

Functions

cv2_to_rgb(→ Optional[numpy.ndarray])	Convert an OpenCV BGR/BGRA array to spaCR's RGB/RGBA contract.
read_image_rgb(→ Optional[numpy.ndarray])	Read with OpenCV and immediately return RGB/RGBA in memory.
rgb_to_cv2(→ numpy.ndarray)	Convert an RGB/RGBA array only for an immediate OpenCV write call.
write_image_rgb(→ bool)	Write an RGB/RGBA array through OpenCV without leaking BGR internally.
