Introduction to bitmaps:

Bitmap images (bitmaps), also known as bitmap images or raster images, are composed of individual points called pixels (picture elements). The dots can be arranged and colored differently to create patterns. When you zoom in on a bitmap, you can see the countless individual squares that make up the entire image.

The effect of expanding the size of a bitmap is to increase the size of individual pixels, making lines and shapes appear jagged. However, if you view it from a slightly greater distance, the color and shape of the bitmap image appear continuous.

Photos taken with a digital camera, pictures scanned by a scanner, and computer screenshots are all bitmaps. The characteristic of bitmap is that it can express color changes and subtle transitions of colors, producing realistic effects. The disadvantage is that it needs to record the position and color value of each pixel when saving, which takes up a large storage space.

Commonly used bitmap processing software includes Photoshop (which also includes vector functions), Painter, and the drawing tools that come with Windows systems. Adobe Illustrator is vector graphics software.
