imencode

imencode(img: np.ndarray, imgtyp: str | int | IMGTYP = IMGTYP.JPEG, **kwargs: object) -> bytes | None

• Description: Encodes a numpy image into bytes with the requested format.

• Parameters

  • img (np.ndarray): Image array.
  • imgtyp (str | int | IMGTYP): Image type. Supports IMGTYP.JPEG / IMGTYP.PNG. Default is IMGTYP.JPEG.

• Returns

  • bytes | None: Encoded bytes; returns None on failure.

• Notes

  • For backward compatibility, IMGTYP=... is also accepted (providing both imgtyp and IMGTYP raises TypeError).

• Example

  from capybara.vision.improc import IMGTYP, imencode, imread
  
  img = imread('lena.png')
  encoded_bytes = imencode(img, imgtyp=IMGTYP.PNG)
