animator.skia.Data

class animator.skia.Data

Bases: pybind11_builtins.pybind11_object

Data supports Python buffer protocol, meaning that Data can be converted to Python buffer types without copy:

bytes(data)
memoryview(data)
np.array(data)

Note

Remember to keep a reference to Data when converting to Python buffer types.

__init__(self: animator.skia.Data, buf: buffer, copy: bool = False) → None

Create a new Data.

Parameters

• buf (bytes|bytearray|memoryview) – Buffer object

• copy (bool) – Whether to copy data, default False.

Methods

MakeEmpty()
MakeFromFileName(path)
MakeSubset(src, offset, length)
MakeUninitialized(length)
MakeWithCString(cstr)	Create a new dataref by copying the specified string or bytes.
MakeWithCopy(data)	Create a new dataref by copying the specified data.
MakeWithoutCopy(data)
MakeZeroInitialized(length)
__init__(self, buf[, copy])	Create a new Data.
bytes(self)	Like :py:meth:~Data.data, returns a read-only ptr into the data, but in this case it is cast to bytes.
copyRange(self, offset, length, buffer)	Helper to copy a range of the data into a caller-provided buffer.
data(self)	Returns the read-only memoryview to the data.
equals(self, other)
isEmpty(self)
size(self)
writable_data(self)	Returns the read-write memoryview to the data.

static MakeEmpty() → animator.skia.Data

static MakeFromFileName(path: str) → animator.skia.Data

static MakeSubset(src: animator.skia.Data, offset: int, length: int) → animator.skia.Data

static MakeUninitialized(length: int) → animator.skia.Data

static MakeWithCString(cstr: str) → animator.skia.Data

Create a new dataref by copying the specified string or bytes.

static MakeWithCopy(data: buffer) → animator.skia.Data

Create a new dataref by copying the specified data.

static MakeWithoutCopy(data: buffer) → animator.skia.Data

static MakeZeroInitialized(length: int) → animator.skia.Data

bytes(self: animator.skia.Data) → bytes

Like :py:meth:~Data.data, returns a read-only ptr into the data, but in this case it is cast to bytes.

copyRange(self: animator.skia.Data, offset: int, length: int, buffer: Optional[buffer]) → int

Helper to copy a range of the data into a caller-provided buffer.

Returns the actual number of bytes copied, after clamping offset and length to the size of the data. If buffer is NULL, it is ignored, and only the computed number of bytes is returned.

data(self: animator.skia.Data) → memoryview

Returns the read-only memoryview to the data.

equals(self: animator.skia.Data, other: animator.skia.Data) → bool

isEmpty(self: animator.skia.Data) → bool

size(self: animator.skia.Data) → int

writable_data(self: animator.skia.Data) → memoryview

Returns the read-write memoryview to the data.
