# Documentation
- Class name: LLMImageTextReader
- Category: SALT/Language Toolkit/Readers
- Output node: False
- Repo Ref: https://github.com/comfyanonymous/ComfyUI

LLMImageTextReader节点用于读取和处理图像，根据用户定义的参数提取文本和附加信息。它利用底层的图像处理和文本提取技术，促进图像内容的分析和解释。

# 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，因为它决定了用于文本提取和进一步处理的源图像。
    - Comfy dtype: STRING
    - Python dtype: str
## Optional
- parse_text
    - 一个布尔标志，指示是否应从图像中提取文本。这影响节点是否会对图像执行文本解析操作。
    - Comfy dtype: COMBO[BOOLEAN]
    - Python dtype: bool
- extra_info
    - 包含额外信息的JSON格式字符串，可用于提供处理图像的附加上下文或指令。
    - Comfy dtype: STRING
    - Python dtype: str

# Output types
- documents
    - 输出是包含图像处理和文本提取结果的文档，其结构化格式便于进一步分析或显示。
    - Comfy dtype: DOCUMENT
    - Python dtype: tuple


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