imagem

Imagem is the Portuguese word for a visual representation, including photographs, drawings, icons, or any graphical depiction. The term derives from Latin imago, meaning likeness.

In computing, an image is a digital or stored representation of a visual scene. Digital images can be raster, made of pixels, or vector, defined by mathematical shapes; both are used in media, web, and software.

Common raster formats include JPEG, PNG, GIF, BMP, and TIFF. Vector formats include SVG and EPS. Formats differ in compression, color support, transparency, and scalability.

Image metadata records properties such as resolution, color space, and camera settings (EXIF). Accessibility practices recommend alt text to describe images for screen readers.

Image processing covers editing and transforming images, including resizing, filtering, compression, and color correction. It supports tasks in photography, design, computer vision, and digital publishing.

Copyright and licensing govern image use. Many images are protected by copyright, but open licenses and permissive formats enable reuse with attribution.
