Raster
Definition:
Raster is a grid-based pattern or structure used in weaving, where threads are organized in a parallel and perpendicular arrangement to create a design. The raster pattern is commonly used in textile weaving to produce intricate designs and motifs on fabrics.
The Concept of Raster
Raster graphics, also known as bitmaps, are digital images composed of a grid of pixels. Each pixel contains specific color information, and when combined, these pixels create a complex image. Raster images are resolution-dependent, meaning that resizing them can lead to a loss of quality since the software has to interpolate pixels to fit the new size.
Advantages of Raster Graphics:
Realism: Raster images are well-suited for photographs and complex images as they can capture intricate details and gradients effectively.
Editing Flexibility: Software like Photoshop allows for extensive editing capabilities on raster images, including color correction, retouching, and adding effects.
Disadvantages of Raster Graphics:
Pixelation: Enlarging a raster image too much can lead to visible pixelation and a loss of clarity.
File Size: Raster images can have larger file sizes compared to vector graphics due to storing color information for each individual pixel.
These characteristics make raster graphics a suitable choice for web graphics, digital art, and photography where precise details and realistic appearance are key factors to consider.
