What is raster and vector ?/Raster and Vector/Raster and Vector k ho ?

 Raster and vector graphics are two different types of digital images, and they differ in how they represent and store visual information.

Raster Graphics:

1. Representation: Raster graphics, also known as bitmap graphics, is made up of a grid of pixels (tiny dots of color).

2. Resolution: The quality of a raster image is determined by its resolution, which is the number of pixels per inch (PPI) or dots per inch (DPI). Higher resolution generally means better image quality.

3. Scalability: Raster images can lose quality when resized because increasing their size means stretching the existing pixels, which can result in a loss of clarity and sharpness.

4. File Formats: Common raster graphic formats include JPEG, PNG, GIF, and BMP.

 

Vector Graphics:

1. Representation: Vector graphics use mathematical equations to create shapes such as lines, circles, and polygons. Instead of pixels, they comprise paths defined by points, lines, and curves.

2. Resolution: Vector graphics are resolution-independent, meaning they can be scaled to any size without loss of quality. This makes them ideal for logos and other designs that need to be resized frequently.

3. Scalability: Vector graphics are highly scalable, and they maintain their sharpness and clarity regardless of the size at which they are displayed.

4. File Formats: Common vector graphic formats include SVG (Scalable Vector Graphics), AI (Adobe Illustrator), and EPS (Encapsulated PostScript).

Use Cases:

Raster Graphics: Best suited for photographs, complex images, and detailed graphics where subtle color variations are important.

-Vector Graphics: Ideal for logos, icons, illustrations, and designs that require scalability without loss of quality.

 

In summary, the main difference lies in the way images are constructed and represented. Raster graphics use pixels and are resolution-dependent, while vector graphics use mathematical equations and are resolution-independent, making them more versatile for certain types of design work.
