In this video we will learn, how to create a image to pdf converter using Python. In this tutorial we are going to use python pillow library .
Pillow is the friendly PIL fork by Alex Clark and Contributors. PIL is the Python Imaging Library by Fredrik Lundh and Contributors. As of 2019, Pillow development is supported by Tidelift.
The Python Imaging Library adds image processing capabilities to your Python interpreter.
This library provides extensive file format support, an efficient internal representation, and fairly powerful image processing capabilities.
The core image library is designed for fast access to data stored in a few basic pixel formats. It should provide a solid foundation for a general image processing tool.

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.
Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is
Syntax: x = lambda arguments : expression
Now i will show you some python lambda function examples:
#python #anonymous function python #filter function in python #lambda #lambda python 3 #map python #python filter #python filter lambda #python lambda #python lambda examples #python map
The Portable Document Format (PDF) is not a WYSIWYG (What You See is What You Get) format. It was developed to be platform-agnostic, independent of the underlying operating system and rendering engines.
To achieve this, PDF was constructed to be interacted with via something more like a programming language, and relies on a series of instructions and operations to achieve a result. In fact, PDF is based on a scripting language - PostScript, which was the first device-independent Page Description Language.
In this guide, we’ll be using pText - a Python library dedicated to reading, manipulating and generating PDF documents. It offers both a low-level model (allowing you access to the exact coordinates and layout if you choose to use those) and a high-level model (where you can delegate the precise calculations of margins, positions, etc to a layout manager).
We’ll take a look at how to create a PDF invoice in Python using pText.

For sharing documents both in hardcopy and digitally, the PDF file format is the preferred choice.Because of its high-versatility and compatibility between different operating systems, the PDF format allows users to create, edit, encrypt, and lock important documents for viewing on any browser or with any PDF viewing application such as Adobe Acrobat. Furthermore, its flexibility means that almost any other file type can be converted into PDF format without loss of quality or corruption of formatting. This means that complex file types such as DOCX and XLSX documents can be converted and shared easily in a protected format that will limit the chance of accidental edits or formatting errors.
However, if you are planning to display examples or insert an image of a PDF document in a separate file or web page, converting your PDF files to an image array will be more useful. For example, if you are creating a PowerPoint showing the on-boarding process for your organization and need to include images of different documents or contracts associated with the process, converting your PDF files into JPG will allow you to quickly and effortlessly insert the image and scale or crop it according to the needs of your presentation. When performing a similar process for a web page, having your document available as a PNG image will optimize it for viewing online within your website. It also prevents users from downloading and editing the document as would be possible with a PDF.
In this article, we will review three Conversion APIs that will allow you to convert any PDF document into an image. This includes conversion to a PNG or JPG array with one image created per page in your document. We will also discuss how you can merge and stack your PDF pages for conversion into a single PNG, or “tall” image.
Our goal for this tutorial is to simplify and improve your versatility for document display and sharing. Furthermore, as most documents can be converted to PDF, you can apply these APIs to any file, post-PDF-conversion. This will greatly increase your deliverable scope and production value.
The first API that we will discuss here provides an automated process for converting a PDF document to a PNG array. As an array, one PNG image will be created of each page within the PDF document, meaning you can choose specific pages for use without need for extra input commands.

Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc…
You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like init, call, str etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).
Now there are a number of such special methods, which you might have come across too, in Python. We will just be taking an example of a few of them to understand how they work and how we can use them.
class AnyClass: def __init__(): print("Init called on its own") obj = AnyClass()
The first example is _init, _and as the name suggests, it is used for initializing objects. Init method is called on its own, ie. whenever an object is created for the class, the init method is called on its own.
The output of the above code will be given below. Note how we did not call the init method and it got invoked as we created an object for class AnyClass.
Init called on its own
Let’s move to some other example, add gives us the ability to access the built in syntax feature of the character +. Let’s see how,
class AnyClass: def __init__(self, var): self.some_var = var def __add__(self, other_obj): print("Calling the add method") return self.some_var + other_obj.some_var obj1 = AnyClass(5) obj2 = AnyClass(6) obj1 + obj2
