What is a proprietary technology that manipulates vector graphics for animations?

Flash technology is a proprietary multimedia software platform that was widely used for creating animations, interactive content, and games on the web. It allowed developers to manipulate vector graphics efficiently, thereby enabling smooth and scalable animations. The proprietary nature of Flash meant that it was developed and controlled by Adobe, giving it unique functionalities that were not available with open standards.

Flash's capability to handle vector graphics was particularly advantageous for animations, as vector graphics can be resized without loss of quality, making them ideal for a variety of screen sizes and resolutions. This was critical in an era when internet speeds and capabilities varied widely.

In contrast, HTML5, CSS3, and SVG, while important technologies in web development, do not specifically serve as proprietary technologies focused on manipulating vector graphics for animations in the same way Flash did. HTML5 provides the structure and functionality for web pages, CSS3 is primarily for styling, and SVG (Scalable Vector Graphics) is an open standard used for creating vector images but does not include the same level of integrated animation capabilities that Flash provided, particularly in its heyday.
