Overview
Sep 04, 2013 This is a quick video on how to download PIL in terminal in easy steps. The scirpts used are sudo easyinstall pip and then after that sudo pip install PIL. Nov 01, 2017 I am trying to install PIL (the Python Imaging Library) using the command: sudo pip install pil. See How can I install PIL on mac os x 10.7.2 Lion. If you use homebrew. Click “Python Imaging Library 1.1.7 Source Kit” to download the source; tar xf Imaging-1.1.7.tar.gz; cd Imaging-1.1.7. The Python Imaging Library (PIL) adds image processing capabilities to your Python interpreter. This library supports many file formats, and provides powerful image processing and graphics capabilities. The current free version is PIL 1.1.7. This release supports Python 1.5.2 and newer, including 2.5 and 2.6. A version for 3.X will be released.
In last post I was writing about PIL, also known as Python Imaging Library, this library can be used to manipulate images quite easy. PIL hasn't seen any development since 2009. Therefore, the kind users of this site suggested to take a look at Pillow. Create new photos library mac sierra. This article well tell you how to use Pillow.
What is Pillow?
Pillow is a fork of PIL (Python Image Library), started and maintained by Alex Clark and Contributors. It was based on the PIL code, and then evolved to a better, modern and more friendly version of PIL. It adds support for opening, manipulating, and saving many different image file formats. A lot of things work the same way as the original PIL.
Download and Installing Pillow
Before we start to use the Pillow, we must first download and install it. Pillow is available for Windows, Mac OS X and Linux. The most recent version is '2.2.1' and is supported by python 2.6 and above. To install Pillow on Windows machines you can use easy_install:
To install Pillow on Linux machines simply use:
To install Pillow on Mac OS X I had to first install XCode and then install the the prerequisites is via Homebrew. After Homebrew was installed, I ran:
Please let me know if you know an easier way to do this on Mac.
Verify that Pillow is installed
To verify that Pillow is installed, open up a Terminal and type in the following line:
If the system comes back with a '>>>', the Pillow modules are properly installed.
File formats
Before we start using the Pillow module, let us mention some of the filetypes that is supported. BMP EPS GIF IM JPEG MSP PCX PNG PPM TIFF WebP ICO PSD PDF Some of the file types, you only have the possibility to read, and others you can only write. To see the full list of supported file types, and more information about them, take a look at the handbook for Pillow.How to use Pillow to manipulate an image
Since we are going to work with images, let us first download one. If you already have a picture to use, go ahead and skip this step. In our example we will use a standard test image called 'Lenna' or 'Lena'. That standard test image is used in many image processing experiment. Just go here and download the picture. If you click on the image, it will save it as an 512×512px image.Using Pillow
Let us look at the possible uses for this library. The basic functions are found in the Image module. You can create instances of this class in several ways either by loading images from files, processing other images, or creating images from scratch. Import the Pillow modules you want to use.
You can then access functions as usual, e.g.
Load an Image
To load an image from your computer, you can use use 'open' method to identify the file, and then load the identified file using myfile.load(). Once the image is loaded, you can do a number of things with it. I often use the try/except block when dealing with files. To load our image using try/except:
When we read files from disk using the open() function, we don't have to know the format of the file to. The library automatically determines the format based on the contents of the file. Now when you have an Image object, you can use the available attributes to examine the file. For example, if you want to see the size of the image, you can call the 'format' attribute.
The 'size' attribute is a 2-tuple containing width and height (in pixels). Common 'modes' are 'L' for greyscale images, 'RGB' for true color images, and 'CMYK' for pre-press images. The output of above should give you this:
Blur an Image
This example will load an image from the hard drive and blurs it. [source]
The blurred image should look like this:
To display the image, we used the 'show()' methods. If you don't see anything, you could try installing ImageMagick first and run the example again.

Creating Thumbnails
A very common thing to do is creating thumbnails for images. Thumbnails are reduced-size versions of pictures but still contains all of the most important aspects of an image. Kontakt 5 library crack mac.

Filters in Pillow
The Pillow module provides the following set of predefined image enhancement filters:
In our last example for today, we will show how you can apply the 'contour' filter to your image. The code below will take our image and apply

I enjoyed to try out Pillow, and I will write more posts about it in the future.

Released:
Image manipulation library for media computation education
Project description
cImage - A simple image processing library for Python
Installation
If using Thonny, go to Tools -> Manage Packages, then enter cs20-image. This should install both the image module, and the Pillow module (so you can use any type of image you’d like).
If you are not using Thonny, copy image.py to your site-packages directory, or just keep it in the same folder as the Python scripts that import it.
Usage
This image library is not going to give you fancy high performance operations on images. It allows you to read in an image and manipulate its pixels. Then you can save the new image to a file, or you can display the image in a window. Thats really about it, but its really all you want to do if you are teaching an introductory computer science course.
Image Types Supported
If you have PIL installed on your system (if you are using Thonny, this was installed along with the image module):
- jpeg
- gif
- tiff
- png
- etc.
If you do not have PIL installed then you are stuck with GIF images only.
