Line art refers to images composed entirely of white pixels and a single colour, typically represented in Photoshop or other graphics software as a bitmap. These images do not contain gradients, shades, or colour blends, relying solely on lines and solid areas to convey form and detail.
Understanding line art is useful for photographers, graphic designers, and illustrators working with digital images, logos, or technical drawings. Line art is ideal for high-contrast reproduction, vector tracing, and situations where clarity and simplicity are essential, such as printing, engraving, or graphic overlays.
