pyflink.multimodal.expression.ImageExpressionAccessor.decode

ImageExpressionAccessor.decode(*, on_error: Literal['raise', 'null'] = 'raise', mode: Optional[str] = None, pixel_limit: Optional[int] = None, concurrency: Optional[int] = None) → pyflink.table.expression.Expression

Decode image bytes into image values.

Equivalent to image_decode(). See that function for full parameter details.

Parameters

• on_error – "raise" to propagate decode failures, or "null" to return null for unreadable inputs.

• mode – Optional output image mode, such as "RGB".

• pixel_limit – Optional maximum decoded pixel count.

• concurrency – Optional execution concurrency for this operation. None uses the framework default.

Returns

A DataFrame expression that produces decoded IMAGE values.
