The document discusses different types of digital graphics, including raster graphics, vector graphics, and various file formats.
Raster graphics are made up of pixels arranged in a grid, with a fixed resolution. They can lose quality when resized. Vector graphics use paths defined by points, lines, and curves that can be resized without losing quality.
JPEG is best for photographs and websites due to its small file size but loses quality with multiple edits. TIFF maintains quality but has large file sizes. PSD saves layers and transparency but only works in Photoshop. AI is for logos and scalable images while 3DS is an industry standard format for 3D modeling.
The document also includes evaluations of different image manipulation tasks
