# Documentation
- Class name: LLMImageVisionLLMReader
- Category: SALT/Language Toolkit/Readers
- Output node: False

LLMImageVisionLLMReader节点旨在读取和处理图像文件，利用大型语言模型（LLMs）来解释和提取视觉内容中的信息。它的目标是通过LLMs的视角，架起视觉数据与文本分析之间的桥梁，从而实现对图像的更深入理解。

# Input types
## Required
- path
    - 指定要处理的图像文件路径。这是一个至关重要的参数，因为它决定了节点将要分析的视觉数据的来源。
    - Comfy dtype: STRING
    - Python dtype: str

## Optional
- extra_info
    - 以字符串格式提供可选的额外信息，可用于影响图像的处理过程。这可能包括特定任务的设置或参数。
    - Comfy dtype: STRING
    - Python dtype: str

# Output types
- documents
    - 将处理后的数据以文档形式返回，封装了LLM从图像中提取的见解。
    - Comfy dtype: DOCUMENT
    - Python dtype: List[Document]


## Usage tips
- Infra type: `CPU`
- Common nodes: unknown
