ImageParser

class ImageParser(ParserBase)

源码Source agentscope/rag/_parser/_image.py:17–92

用于图像文件的解析器。位于 agentscope.rag 包，继承自 ParserBase。核心成员包括 supported_extensions、parse。

Wraps the entire file as a single :class:Section holding a :class:DataBlock with the image's base64-encoded bytes. This is the input shape a multimodal embedding model expects; the surrounding pipeline (chunker, vector store) treats the section opaquely.

The IANA media type is sniffed from the bytes' magic number so callers do not need to pass it explicitly.
