Rasterize is a fundamental process in digital graphics and design that involves converting a vector-based image, which is defined by mathematical equations and geometric primitives, into a raster or bitmap image composed of a grid of pixels. This transformation is essential when preparing vector graphics for display on digital screens or for printing, as most output devices, such as monitors and printers, operate on a pixel-by-pixel basis. The rasterization process determines the color and intensity of each pixel in the output image by sampling the vector graphic at discrete points and applying various rendering techniques, such as anti-aliasing, to minimize visual artifacts and maintain the appearance of smooth lines and curves. The resulting raster image has a fixed resolution and cannot be scaled up without loss of quality, unlike vector graphics which retain their sharpness and detail at any size. Rasterization is a key concept in digital imaging software, where designers often work with a combination of vector and raster elements to create complex compositions. The choice between vector and raster formats depends on the intended use of the graphic, with vectors being preferred for logos, illustrations, and scalable designs, while rasters are ideal for photographs, detailed textures, and final output. Interestingly, the term rasterize originated from the Latin word rastrum, which refers to a rake-like tool used for scratching or engraving, drawing parallels to the process of rendering an image line by line.

Rasterize is the process of converting a vector graphic, which is composed of paths, curves, and shapes, into a raster image made up of pixels. This transformation is essential in digital graphics, as it enables vector-based artwork to be displayed on pixel-based screens and output devices. The rasterization process involves sampling the vector graphic at a specific resolution and generating a grid of pixels that approximates the original image. The resulting raster image has a fixed dimensions and resolution, and each pixel is assigned a color value. While rasterization allows for the display and printing of vector graphics, it also introduces some limitations. Raster images cannot be scaled up without losing quality, as the pixels become more apparent when the image is enlarged. Additionally, raster images have larger file sizes compared to vector graphics, as they store color information for each individual pixel. Despite these limitations, rasterization remains a crucial process in digital imaging, enabling the integration of vector artwork into pixel-based environments such as web graphics, digital photography, and computer displays.
