Drawing Programs vs. Painting Programs
Mayura Draw is a vector-based drawing program.
Unlike painting programs, which are bitmap-based, a drawing program
stores your picture as lines, circles, polygons, text and other
geometric shapes.
This lets you modify your illustration by changing the radius
of a circle, for example, or by deleting a node from a polygon.
Painting programs on the other hand store your picture as an array of
pixels. This lets you modify individual pixels of your picture, but you
cannot, for example, modify the radius of a circle once it is drawn.
Drawing programs can let you resize your picture with no loss in
resolution. Also, when the picture is printed on a high-resolution
printer no 'staircasing' effect is visible.
Painting programs cannot print at the full resolution of the printer,
so staircasing will be visible.
