logging HeifFile.data shows input file type bytes rather than heic converted bytes

[Barnards]

heif_file = pillow_heif.from_bytes(mode='RGBA', size=(595,842), data=jpeg_bytes)
print(heif_file.data)

log seems to show jpeg bytes rather than heic bytes, have I missed something?

Can you please elaborate a bit?
content heif_file.data will be equal to jpeg_bytes, as you code just created HeifFile class from provided raw image data(jpeg_bytes)

If you want to get encoded HEIC or AVIF file from jpeg_bytes you need to call heif_file.save("output.heic")

Or you can directly call pillow_heif.encode(mode='RGBA', size=(595,842), data=jpeg_bytes, "output.heic")

Thanks for the quick response, I'm new to all things image code related. I had initially gotten a bug when I had attempted .encode() before I approached you, turns out there was a mismatch in jpeg size and format vs the size and format I was attempting to encode. With your advice on going the encode route I've had success with this code:

`def convert_jpeg_bytes_to_heic_bytes(jpeg_bytes):

heic_file_name = 'file_conversion_test.heic'
input_stream = BytesIO(jpeg_bytes)
img = Image.open(input_stream)

if img.mode != 'RGBA':
    img = img.convert('RGBA')

raw_data = img.tobytes()

pillow_heif.encode(
    mode=img.mode, 
    size=img.size, 
    data=raw_data,
    fp=heic_file_name
)

pillow_heif.register_heif_opener()

with open(heic_file_name, "rb") as file:
    heic_bytes = file.read()

input_stream.close()

os.remove(heic_file_name)

return heic_bytes`

Grateful for this library
