What are bitmap images created from?

Bitmap images are created from a grid of small squares called pixels. Each pixel represents a small portion of the overall image and carries color information. When these pixels are combined in a grid formation, they collectively form a complete image. This structure allows for detailed and intricate designs, but it does mean that bitmap images can lose quality if scaled up, as they are resolution-dependent.

Other options touch upon elements used in graphic design but do not accurately describe the fundamental nature of bitmap images. For instance, mathematically defined shapes and curves pertain to vector graphics, which are composed of paths rather than pixels. Meanwhile, vectors and paths specifically refer to vector graphics that utilize mathematical equations to create images, allowing them to be resized without loss of quality. A blend of raster and vector graphics might refer to certain hybrid designs or compositing techniques but does not define what bitmap images inherently are.
