There are two main types of 2D graphics - bitmaps and vectors. Bitmaps are made up of pixels and can become pixilated when stretched, while vectors are defined by mathematical equations and maintain high quality when resized. Resolution refers to the number of pixels in an image, with higher resolution resulting in clearer images. When editing images, tools like cropping, handles, bounding boxes, standoff, text wrap, proportion, and skewing can be used. Standard page sizes for documents include letter, legal, and tabloid, but custom sizes can also be used. Graphics should not crowd the page and it's best to have one dominant graphic while varying graphic sizes and shapes.
