Theory:

Raster graphics:
The picture or image that raster graphics creates is entered 'as file and data'.
The Pictures are of two types;
  • Vector
  • Raster
Raster Graphics are created on the basis of PIXELS.
 
The photos taken by the camera and the photos scanned by a scanner are of the raster type. When we enlarge this type of photo, we could see the pictures as rectangular layers or grids.
Raster File Types:
  • .png (Portable Network Graphics)
  • .jpg or .jpeg (Joint Photo graphics Experts Group)
  • .gif (Graphics interchange Format)
  • .tiff (Tagged Image File Format)
  • .psd (Photoshop Document)

The Software which edits the Raster Graphics:
  • Adobe Photoshop
  • Vector Graphics
As the Vector Pictures are created based of Mathematics, even when we enlarge the picture, its accuracy will not change.
Types of Vector Graphics Files
  • .eps (Encapsulated Post Script)
  • .ai (Adobe Illustrator Artwork)
  • .pdf (Portable Document Format)
  • .svg (Scalable Vector Graphics)
  • .sketch
The Software which we use to edit the Vector Graphic Images are
  • Adobe Illustrator
  • Sketch
  • Inkscape
