Usage of Inpaint Anything Library

Introduction

The inpalib from the extensions.sd-webui-inpaint-anything package lets you segment images and create masks using sketches from other extensions.

Code Breakdown

Imports and Module Initialization

import importlib

import numpy as np
from PIL import Image, ImageDraw

inpalib = importlib.import_module("extensions.sd-webui-inpaint-anything.inpalib")

Fetch Model IDs

available_sam_ids = inpalib.get_available_sam_ids()

use_sam_id = "sam_hq_vit_l.pth"
# assert use_sam_id in available_sam_ids, f"Invalid SAM ID: {use_sam_id}"

Note: Only the models downloaded via the Inpaint Anything extension are available.

Generate Segments Image

input_image = np.array(Image.open("/path/to/image.png"))

sam_masks = inpalib.generate_sam_masks(input_image, use_sam_id, anime_style_chk=False)
sam_masks = inpalib.sort_masks_by_area(sam_masks)

seg_color_image = inpalib.create_seg_color_image(input_image, sam_masks)

Image.fromarray(seg_color_image).save("/path/to/seg_color_image.png")

Create Mask from Sketch

sketch_image = Image.fromarray(np.zeros_like(input_image))

draw = ImageDraw.Draw(sketch_image)
draw.point((input_image.shape[1] // 2, input_image.shape[0] // 2), fill=(255, 255, 255))

mask_image = inpalib.create_mask_image(np.array(sketch_image), sam_masks, ignore_black_chk=True)

Image.fromarray(mask_image).save("/path/to/mask_image.png")

Note: Ensure you adjust the file paths before executing the code.
