A vector image refers to a series of points connected by lines. It is an image represented in computer graphics using geometric primitives based on mathematical equations such as points, lines, or polygons. A vector can be a point or a line. Vector graphics can only be generated by software. The file takes up less internal space because this type of image file contains independent separated images that can be freely recombined without restrictions.
Bitmaps are composed of individual points of picture elements. The dots can be arranged and colored differently to create patterns. When you zoom in on a bitmap, you can see the numerous individual squares that make up the entire image. The effect of increasing the size of a bitmap is to enlarge individual pixels, making lines and shapes appear jagged. The characteristic of bitmap is that it can express color changes and subtle transitions of colors, producing realistic effects.
Extended information:
When processing bitmaps, the quality of the output image depends on the resolution set at the beginning of the processing process. When working with bitmaps, resolution affects both the quality of the final output and the file size. The resolution chosen for an image when working with bitmaps usually accompanies the file throughout the process.
Whether a bitmap file is printed on a 300dpi printer or a 2570dpi phototypesetting device, the file is always printed at the resolution set when the image was created, unless the printer's resolution is lower than the image's resolution. Rate. If you want your final output to look the same as what's displayed on the screen, you need to understand the relationship between the resolution of your image and the resolution of different devices before you start working.
