Method to implement image capture function based on PyGraphics package in Python

This article describes the method of implementing the image capture function based on the PyGraphics package in Python. Share it with everyone for reference, as follows:

Firstly install the PyGraphics package (python import media module)

There is a piece of code to import media, open the Python built-in IDLE, and input:

>>>import media

It will prompt that there is no media module!

The media module is not a standard system module, and it needs to be installed with third-party software before it can be used. This library is in PyGraphics, but PyGraphics depends on some other libraries. You can install it in this way (refer to here:http://packages.python.org/PyGraphics/install.html）：

Download: Python Imaging Library 117 for Python 27-->Install
Download: pygame-191.win32-py27.msi-->Install
Download: numpy-161-win32-superpack-Python27.exe-->Install
Download: ampy-123.win32.exe-->Install
http://pragprog.com/titles/gwpy/source_code Download gwpy-code.zip After unzipping, extract code-->install-->PyGraphics-2.0.win32.exe-->Install

If you want to use the tests in the PyGraphics package, you must download and install the Nose package as follows:

Firstly, download: setuptool-->Install

Secondly, open cmd-->Enter the command prompt, at this time, keep the computer connected to the Internet, and input C:\Python in the command prompt.27\Scripts\easy_install nose Enter, at this time, it will automatically download things from the Internet, don't worry about it, Nose will automatically complete the installation.

Note: Here C:\Python27It refers to the folder where Python is located, and you can change it if necessary!

Now you can use all the contents of the PyGraphics package~~ For example: the media module, picture module, pixel module, color module, sound module, and so on.

Alright, now try import media in IDLE, and the error will no longer occur!

Reference:

http://packages.python.org/PyGraphics/
http://packages.python.org/PyGraphics/install.html

Open the image

>>>import media
>>>f=media.choose_file()
>>>pic=media.load_picture(f)
>>>media.show(pic)

Get the length and width of the image

>>>pic.get_width()
...
>>>pic.get_height()
...
>>>pic.title
...

Image Cropping

>>>media.crop_picture(pic,150,50,450,300) # top left (150,50) bottom right (450,300)
>>>media.show(pic)
>>>media.save_as(pic,'new_.jpg')
