Understanding Image Resolution
The resolution of an image plays a crucial role in determining its clarity and print quality. To understand image resolution, it’s important to differentiate between pixels per inch (PPI) and dots per inch (DPI). PPI refers to the number of pixels on a computer screen, while DPI refers to the ink dots per inch applied by a printing press. While these terms are often used interchangeably, they have distinct meanings and applications.
Image resolution specifically applies to raster images, which are composed of pixels. On the other hand, vector images use mathematical calculations to define shapes and lines, allowing for scalability without loss of quality. It’s important to work with the appropriate image type for different purposes. Raster images are commonly used for photographs and digital graphics, while vector images are preferred for logos, icons, and illustrations.
The Difference Between Raster and Vector Images
When it comes to understanding image resolution, it’s essential to recognize the differences between raster and vector images. Raster images, as mentioned before, are composed of pixels and have a fixed resolution. This means that when a raster image is enlarged or zoomed in, the pixels become more visible, resulting in a loss of quality and sharpness.
On the other hand, vector images are defined by mathematical equations, allowing them to be scaled up or down without losing quality. This is because vector images are composed of lines, curves, and shapes that can be easily modified and adjusted. As a result, vector graphics are ideal for designs that require flexibility and scalability, such as logos and illustrations.
| Raster Images | Vector Images | |
|---|---|---|
| Definition | Composed of pixels | Composed of mathematical equations |
| Resolution | Has a fixed resolution | Can be scaled up or down without losing quality |
| Scaling | Enlarging the image may result in pixelation | Can be scaled without losing quality |
| Uses | Photographs, digital graphics | Logos, icons, illustrations |
