Python write_box Examples

Example #1

File: ric_encoder.py Project: dbsima/responsive-image-format

def ric_encode(imgbuf, config):
    img = Image.open(StringIO(imgbuf))
    layers = Coder().encode(img, config)

    output += iso_media.write_box("FTYP", "RIC ")
    output += iso_media.write_box("ILOT", write_layer_offsets(offsetTable))
    output += wrapped_layers
    return output

Example #2

def ric_encode(imgbuf, config):
    img = Image.open(StringIO(imgbuf))

Example #3

File: wrapper.py Project: dbsima/responsive-image-format
