Cara menggunakan make background transparent python

If we want to convert a picture background into transparent, we can use the Pillow package in Python to do it.

If you want to know more how to use Pillow module, you can refer to here: https://pillow.readthedocs.io/en/3.0.x/handbook/tutorial.html

Convert the background of the picture to transparent

Assume I have a picture as follows:

It is a picture in .jpg format.

As we can see, most of the background color is white color (rgb(255, 255, 255)). So in below, we use the Pillow package to perform conversion processing.

If it is the first time to use Pillow, use the following command to install it:

pip3 install pillow

After the installation is over, let's look at an example:

# -*- coding: utf-8 -*-
from PIL import Image

image = Image.open('input.jpg')
print(image)
print(image.mode)

Output:

<PIL.Image.Image image mode=RGBA size=626x417 at 0x179240973C8>
RGB

We can see that this is a file of PIL.Image.Image data type, and the mode of this file is "RGB".

To make the image background transparent, we need to change "RGB" to "RGBA" first. RGBA stands for Red, Green, Blue and Alpha channel.

Alpha channel stands for transparency. This is why we need to convert to this format.

image = image.convert('RGBA')

print(image.mode)

Output:

RGBA

Then we first take out the pixel value of this picture and determine whether the pixel is white (255, 255, 255):

# Transparency
newImage = []
for item in image.getdata():
    if item[:3] == (255, 255, 255):
        newImage.append((255, 255, 255, 0))
    else:
        newImage.append(item)

image.putdata(newImage)

As you can see, I replaced all dots with pixel values (255, 255, 255) with transparent. Of course, you can set what color you want to convert here.

image.save('output.png')

Finally, remember to save the picture in PNG format. JPG format does not seem to support transparent backgrounds.

The background of this one is already transparent. Of course, if the background is all white, there is no obvious difference, hahaha.

Create a Website from Scratch

A "Layout Draft"

It can be wise to draw a layout draft of the page design before creating a website:

Side Content

Some text some text..

Main Content

Some text some text..

First Step - Basic HTML Page

HTML is the standard markup language for creating websites and CSS is the language that describes the style of an HTML document. We will combine HTML and CSS to create a basic web page.
