Computer art based on joining transparent images

Primary LanguagePython

Computer Art

There is no must in art because art is free.

Introduction

The following tutorial exaplains how to generate computer art based on a series of predefined digital images. Our script will combinate all the digital images generating an specific image collection

Example Case

We will use the following digital assets:

  • 4 x backgrounds images
  • 12 x bodies images
  • 12 x faces images

Expected Results

Our script will generate 576 new images as a result of combinate 4 x 12 x 12 (backgrounds, bodies, and faces).

Example

Environment

The script was successfully tested with:

  • Python 3.8.5
  • Pip 21.2.4
  • Pillow 8.3.2

Digital Assets

There is an images folder with 3 sub-folders

  • /images/backgrounds
  • /images/bodies
  • /images/faces

Inside each sub-folder there is a few transparent png files named with 2-left pad zero strategy, for example: 01.png, 02.png, ..., 11.png

Script Strategy

1. Import Pillow Module

# importing the Pillow module
from PIL import Image, ImageDraw, ImageFilter

2. Define how many digital assets will combine

# my primary source :D
kBackgrounds = 4
kBodies = 12
kFaces = 12

3. Loop in order

for index_background in range(1, kBackgrounds + 1):
    for index_body in range(1, kBodies + 1):
        for index_face in range(1, kFaces + 1):

4. Load the 3 images that will generate the current new image

            im1 = Image.open(/path/to/index_background.png)
            im2 = Image.open(/path/to/index_body.png)
            im3 = Image.open(/path/to/index_face.png)

5. Paste img2 and img3 into img1 in the right position

Example

The magic happens because all the bodies and all the faces have the same canvas/size!

            # paste body into background
            im1.paste(im2, (540, 1970), mask=im2)
            # paste face into background
            im1.paste(im3, (456, 370), mask=im3)

6. Save & continue the loop with the next combination!

            # save!
            im1.save(/path/to/new-image.png)

            # update status!
            print(/path/to/new-image.png, "was successfully created.")

Bye!
