Today, I created one python tool script with the artificial intelligence to merge sprites images.
I used the artificial intelligence to add unittest to create default images with PIL to test the result.
You can select your folder , select the align of merge features or test with unittest button.
This is the result and works well:
import os
import unittest
from PIL import Image, ImageDraw, ImageFont, ImageQt
import shutil

def create_test_image(path, size, number):
img = Image.new('RGBA', size, (255, 255, 255, 255))
draw = ImageDraw.Draw(img)
# Simplified to just draw the number with a basic color background
draw.rectangle((0, 0, size[0], size[1]), fill=(0, 100 * number % 255, 0, 255))
try:
font = ImageFont.load_default()
except:
font = None
draw.text((size[0]//2-5, size[1]//2-5), str(number), fill=(255, 255, 255, 255), font=font)
img.save(path, 'PNG')
def merge_sprites(folder_path, output_horizontal, output_vertical):
images = [Image.open(os.path.join(folder_path, f)) for f in os.listdir(folder_path) if f.endswith(('.png', '.jpg', '.jpeg'))]
if not images:
return None, None
width, height = images[0].size
# Horizontal merge
total_width = width * len(images)
horizontal_image = Image.new('RGBA', (total_width, height))
for i, img in enumerate(images):
horizontal_image.paste(img, (i * width, 0))
horizontal_image.save(output_horizontal, 'PNG')
# Vertical merge
total_height = height * len(images)
vertical_image = Image.new('RGBA', (width, total_height))
for i, img in enumerate(images):
vertical_image.paste(img, (0, i * height))
vertical_image.save(output_vertical, 'PNG')
return horizontal_image, vertical_image
