stable-diffusion-image-metadata

This tool provides the capability to extract and parse metadata from images. It is inspired by the work of the civitai project and leverages some of their code for image metadata parses

About for the processing of parameters, there are two steps.

• (1) Preprocessing, which extracts special attributes in a 'RegExp'
• (2) Extracting the primary attributes with 'split(': ') and split(', ')'

Installation
