BBC – GCSE Bitesize: Graphics editing software

Bitmap graphics consist of many tiny dots called pixels. It is possible to edit each individual pixel using bitmap graphics software like Adobe Photoshop or GIMP. The amount of detail you can draw depends on the number of pixels per square inch (PSI). Since the computer has to store information about every single pixel in the image, the file size of a bitmap graphic is often quite large. When you resize a bitmap graphic, it tends to lose quality.

Vector paths can be used to make shape objects. It is possible to edit each shape object separately, for example, to change the shape, outline type (stroke), fill, size or position. When a vector graphic is resized, it doesn't lose quality. This is because the software works out the new relationships between control points and redraws the image at the new size. Vector graphics do not store information about each pixel so file size does not depend on image size. Instead it depends on how much detail is in the image.
