abraia 0.7.2

Abraia Python SDK

Abraia API client

Batch resize, crop, convert, and compress images from the command line and get perfectly optimized images for web and mobile apps.

• Automatically resize and crop images to an specific size with smart cropping technology balancing content and aesthetics.
• Convert SVGs to PNG or WebP images preserving the transparent background, or add a color to generate JPEG or WebP images.
• Automatically optimize images with no quality damage based perception-driven technology.

Choose an specific size, select the background color, and convert and optimize images for web (JPEG, PNG, WebP).

Abraia command line

The Abraia CLI tool provides a simple way to bulk resize, convert, and optimize your images and photos for web. Enabling the conversion from different input formats to get images in the right formats to be used in the web - JPEG, WebP, or PNG -. Moreover, it supports a number of transformations that can be applied to image batches. So you can easily convert your images to be directly published on the web.

For instance, you can optimize all the images in a folder with the simple command bellow:

abraia convert images

Installation

The Abraia CLI is a Python tool which can be installed on Windows, Mac, and Linux:

python -m pip install -U abraia

The first time you run Abraia CLI you need to configure your API key, just write the command bellow and paste your key.

abraia configure

Resize images

To compress an image you just need to specify the input and output paths for the image:

abraia convert images/birds.jpg images/birds_o.jpg

To resize and optimize and image maintaining the aspect ratio is enough to specify the width or the height of the new image:

abraia convert --width 500 images/usain-bolt.jpeg images/usaint-bolt_500.jpeg

You can also automatically change the aspect ratio specifying both width and height parameters and setting the resize mode (pad, crop, thumb):

abraia convert --width 333 --height 333 --mode pad images/lion.jpg images/lion_333x333.jpg
abraia convert --width 333 --height 333 images/lion.jpg images/lion_333x333.jpg

So, you can automatically resize all the images in a specific folder preserving the aspect ration of each image just specifying the target width or height:

abraia convert --width 300 [path] [dest]

Or, automatically pad or crop all the images contained in the folder specifying both width and height:

abraia convert --width 300 --height 300 --mode crop [path] [dest]

Convert images

The JPEG image format is still the most common format to publish photos on the web. However, converting images to WebP provides a significant improvement for web publishing.

To convert images to a web format (JPEG, PNG, WebP) or between these formats you just need to change the filename extension for the destination file:

abraia convert garlic.jpg garlic.webp

In addition, you can also convert SVG and PSD files. For instance, converting a SVG to PNG is so simple as to type the command bellow:

abraia convert bat.svg bat.png

The SVG vector image is rendered in a Chrome instance to provide maximum fidelity, and preserving the transparent background.

Moreover, you can easily convert a PSD file (the layered image file used in Adobe Photoshop for saving data) flattening all the visible layers with a command like bellow:

abraia convert strawberry.psd strawberry.jpg
abraia convert strawberry.psd strawberry.png

When the PSD file is converted to JPEG a white background is added automatically, because the JPEG format does not support transparency. Instead, using the PNG or the WebP format you can preserve the transparent background.

Or, convert a batch of Photoshop files with a simple command. Just copy your PSD files to a folder, for instance the photoshop folder, and convert all the files in that folder.

abraia convert photoshop

You can also take web from the command line just specifying and url to get the capture.

abraia convert https://abraia.me screenshot.jpg

Watermark images

Using templates images can be easily edited and consistently branded. You just need to create a template in the web editor to watermark your images.

abraia convert --width 333 --action 'test.atn' lion.jpg lion_brand.jpg

As a result you get a perfectly branded and optimized image ready to be used on your website, ecommerce, marketplace, or social media.

Abraia python API

The Abraia python API provides and easy way to automate image transformations. For instance, to optimize a batch of JPEG images limiting the maximum size to 2000 pixels width:

from glob import glob
from abraia import Abraia

abraia = Abraia()

paths = glob('images/*.jpg')
for path in paths:
    res = abraia.upload(path)
    abraia.transform(res['path'], path+'o', {'width': 2000})

You can directly start from your browser with one of the notebooks available. Just click on notebook link bellow:

• Getting started

Configuration

Installed the package, you have to configure your ABRAIA KEY as environment variable:

export ABRAIA_KEY=api_key

On Windows you need to use set instead of export:

set ABRAIA_KEY=api_key

NOTE: To persist the configuration use your system options to set your ABRAIA_KEY environment variable and avoid to run the previous command every time you start a terminal/console session.

Usage

Abraia provides a direct interface to directly load and save images. You can easily load the image data and the file metadata, or save a new image.

from abraia import Abraia

abraia = Abraia()
f = abraia.load('test.jpg')
meta = abraia.metadata('test.jpg')
abraia.save('test.jpg', f)

You can directly visualize the image using Matplotlib.

from PIL import Image

import numpy as np
import matplotlib.pyplot as plt

img = np.asarray(Image.open(f))

plt.figure()
plt.title('Image')
plt.imshow(img)
plt.axis('off')
plt.show()

List files

Retrieve information about all the files stored in a cloud folder.

folder = ''
files, folders = abraia.list(folder)

Return the list of files and folders on the specified cloud folder.

Upload files

Upload a local (src) or a remote (url) file to the cloud.

src = 'test.png'
path = 'test/test.png'
abraia.upload(src, path)

This creates the resource on the cloud and returns the file data, when the process is finished.

url = 'http://upload.wikimedia.org/wikipedia/commons/1/13/Usain_Bolt_16082009_Berlin.JPG'
abraia.upload(url, 'usain.jpg')

Download files

Retrieve an stored file.

path = 'test/birds.jpg'
dest = 'birds.jpg'
abraia.download(path, dest)

Delete files

Delete a stored resource specified by its path.

abraia.delete(path)

Transform images

Transform and optimize images. The service will automatically choose every compression parameter to provide the best result based on the perceived analysis of the original image.

path = 'test/birds.jpg'
dest = 'birds_o.jpg'
params = {'width': 300, 'height': 300, 'mode': 'pad'}
abraia.transform(path, dest, params)
