Aspose.Total for Python via .NET" is a comprehensive package of APIs that can help a Python developer automate the process of converting a PNG to OST format within an application. It contains APIs for dealing with different formats such as Email, Images and Microsoft Word. The conversion process is a two-step process. Firstly, the Word file is loaded and rendered into HTML using the “Aspose.Words for Python via .NET” API. Secondly, the converted HTML is loaded using the “Aspose.Email for Python via .NET” API and saved into the OST format. This API package makes the conversion process easy and efficient for Python developers. The “Aspose.Total for Python via .NET” package is a great tool for Python developers who are looking to add a PNG to OST conversion feature within their applications. It provides a comprehensive set of APIs that can help automate the conversion process. The two-step process of loading the Word file and rendering it into HTML, followed by loading the converted HTML and saving it into the OST format, makes the conversion process easy and efficient. With this package, Python developers can quickly and easily add a PNG to OST conversion feature to their applications.

How to Convert PNG to OST in Python

  • Open the source PNG file using Document class
  • Call the save method while specifying output HTML file path and relevant HTML Save options as parameter. So your PNG file is converted to HTML at the specified path
  • Now Load the saved HTML file using MailMessage.load
  • Call the save method with relevant file path. So finally the PNG is converted

Conversion Requirements

  • For PNG to OST conversion, Python 3.5 or later is required
  • Reference APIs within the project directly from PyPI ( Aspose.Words and Aspose.Email )
  • Or use the following pip command pip install aspose.words and pip install Aspose.Email-for-Python-via-NET
  • Moreover, Microsoft Windows or Linux based OS (see more for Words and Email ) and for Linux check additional requirements for gcc and libpython and follow step by step instructions INSTALL

What is PNG File Format?

PNG (Portable Network Graphics) is a widely used raster graphics file format that was designed as a replacement for the older GIF (Graphics Interchange Format) format. Unlike GIF, which has a limited color palette and supports only indexed colors, PNG supports true color and grayscale images with a rich color depth.

The PNG format utilizes lossless compression, which means that it can reduce file size without sacrificing image quality. This makes it suitable for storing graphics that require high detail and clarity, such as photographs, illustrations, and logos. PNG files are often used on the web for images that need transparency, as PNG supports alpha channel transparency, allowing for smooth blending of images onto different backgrounds.

One of the advantages of PNG is that it supports both interlaced and non-interlaced images. Interlaced PNGs load gradually, displaying a low-resolution version of the image before progressively rendering the higher-resolution details. This feature is especially useful for large images or slow internet connections, as it provides a better user experience by showing a preview while the image loads.

PNG files can be created and edited with various graphics software, such as Adobe Photoshop, GIMP, and Paint.NET. They are widely supported by modern web browsers, image viewers, and editing tools across different operating systems.

What is OST File Format?

OST (Offline Storage Table) is a file format used by Microsoft Outlook to store offline copies of user mailbox data. When working with Microsoft Exchange Server, Outlook allows users to work in cached mode, where a local copy of the mailbox data is stored on the user’s computer. This local copy is saved in the OST file format.

OST files enable users to access their mailbox data even when they are not connected to the Exchange server. Any changes made to the mailbox data while working offline, such as composing or deleting emails, are synchronized with the Exchange server once the user reconnects.

OST files store various types of data, including emails, contacts, calendars, tasks, and other mailbox items. They maintain the folder structure and item hierarchy of the user’s mailbox, allowing for a seamless offline experience.

One of the key benefits of OST files is their ability to facilitate offline access and data synchronization. Users can continue to work with their mailbox data, even without an active internet connection, and all changes are synchronized automatically when connectivity is restored.

It’s important to note that OST files are tied to the specific Outlook profile and Exchange account they were created for. They cannot be opened or accessed independently and require the original Outlook profile to function properly.
