Introduction

Earlier chapters of the Draw Guide have dealt only with vector graphics, that is, images created by mathematical formulas that specify the relationships between the elements of the image. However, Draw also contains several functions for handling raster graphics (also called bitmaps), photographs, and scanned pictures, as well as imports, exports, and conversions from one format to another.

Draw can read all common graphics file formats. It has some of the same capabilities as specialized programs like Adobe Photoshop or Gimp.
