Raster Graphic

What does Raster Graphic mean?

A raster graphic, also known as a Bitmap graphic, is a digital image composed of a grid of pixels, each pixel representing a single color. Raster graphics are created using a variety of techniques, including drawing, painting, and scanning. They are commonly used in computer graphics, digital photography, and printing.

Raster graphics are different from vector graphics, which are composed of paths and shapes. Vector graphics can be scaled to any size without losing quality, while raster graphics become pixelated when scaled up. However, raster graphics can represent a wider range of colors and shades than vector graphics.

Applications

Raster graphics are used in a wide variety of applications, including:

• Computer graphics: Raster graphics are used in computer graphics to create digital images for websites, games, and other applications.
• Digital photography: Raster graphics are used in digital photography to capture and store images taken with digital cameras.
• Printing: Raster graphics are used in printing to create high-resolution images for brochures, magazines, and other printed materials.
• Web design: Raster graphics are used in web design to create images for websites and social media.

Raster graphics are important in technology today because they are the most common type of digital image. They are used in a wide variety of applications, and they can be easily created and edited using a variety of software programs.

History

The history of raster graphics can be traced back to the early days of Computing. In the 1950s, engineers developed the first raster-based computer displays. These displays used a grid of pixels to represent images, and they were capable of displaying a limited Number of colors.

In the 1960s, raster graphics began to be used in television Broadcasting. The first raster-based television cameras were developed, and they allowed for the transmission of moving images.

In the 1970s, raster graphics began to be used in personal computers. The first personal computers with raster-based displays were released, and they allowed users to create and edit their own digital images.

In the 1980s, raster graphics became the standard for digital photography. The first digital cameras were released, and they used raster-based sensors to capture images.

In the 1990s, raster graphics began to be used in the World Wide Web. The first web browsers were released, and they allowed users to view raster-based images on websites.

Today, raster graphics are used in a wide variety of applications. They are the most common type of digital image, and they are used in everything from computer graphics to digital photography to printing.
