draw image as grid on notebook

simply check below code and example result.

.

def image_grid(imgs, rows, cols):

assert len(imgs) == rows*cols

w, h = imgs[0].size

grid = Image.new('RGB', size=(cols*w, rows*h))

grid_w, grid_h = grid.size

for i, img in enumerate(imgs):

grid.paste(img, box=(i%cols*w, i//cols*h))

return grid

# read image prompt

image = Image.open("assets/images/statue.png")

depth_map = Image.open("assets/structure_controls/depth.png")

image_grid([image.resize((256, 256)), depth_map.resize((256, 256))], 1, 2)

..

Thank you.

crop image with grid, python

Example is to do:

Grid 5x5 and resize 200x200

Each image is numpy type.

import cv2

import numpy as np

img = cv2.imread("./data/example.jpg")

def img_to_grid(img, row, col, resize_row, resize_col):

ww = [[i.min(), i.max()] for i in np.array_split(range(img.shape[0]),row)]

hh = [[i.min(), i.max()] for i in np.array_split(range(img.shape[1]),col)]

grid = [img[j:jj,i:ii,:] for j,jj in ww for i,ii in hh]

re_grid=[]

for img in grid:

resized = cv2.resize(img, (resize_row,resize_col), interpolation = cv2.INTER_AREA)

re_grid.append(resized)

return re_grid, len(ww), len(hh)

#------------------------------------

how_many_row, how_many_col = 5, 5

resize_row, resize_col = 200, 200

grid , r,c = img_to_grid(img, how_many_row, how_many_col, resize_row, resize_col)

print(type(grid), type(grid[0]), len(grid), r, c)
