pdft.io.CompressedImage

class pdft.io.CompressedImage(indices, values_real, values_imag, original_size, basis_hash)

Bases: object

Sparse frequency-domain representation of an image.

Mirror of upstream src/compression.jl:27-33. indices are 1-based column-major linear indices into the frequency-domain matrix (Julia convention, chosen for cross-language JSON interop).

Parameters:

• indices (list[int])

• values_real (list[float])

• values_imag (list[float])

• original_size (tuple[int, int])

• basis_hash (str)

__init__(indices, values_real, values_imag, original_size, basis_hash)

Parameters:

• indices (list[int])

• values_real (list[float])

• values_imag (list[float])

• original_size (tuple[int, int])

• basis_hash (str)

Return type:

None
