This document defines key concepts in CorelDRAW including that it is a vector-based drawing program used to create professional graphics. Vector images store graphical elements as mathematical points and lines, allowing objects to be scaled and manipulated independently without quality loss. Bitmap images store pixels in a grid, so enlarging reduces resolution. The document contrasts vector and bitmap images, and defines resolution and pixels. It then describes the CorelDRAW interface including tools, properties bar, drawing page, and other panels.

By the end of the lesson, student will be
able to:
Define Corel Draw
Explain a software
Differentiate between a vectorimage &
a bitmap image
Define resolution

4. Meaning of corel draw
Corel Draw is a vector-based drawing
program(software) that makes it
easy to create professional artwork
from simple logos to intricate
technical illustrations.
It provides tools and effects that
make it possible to workefficiently
to produce high-quality graphics.

5. Drawings in Corel Draw are vector
based because objects drawn are
defined mathematically as a series of
points(dots) joined by lines. Graphical
elements in a vectorfile called
objects. Each object is a self
contained entity, with properties such
as colour, shape, outline, size and
position on the screen included in its
definition.

6. Because each object is a self-contained
entity, it is also possible to move and
change its properties freely while
maintaining its original clarity and
crispness without affecting otherobjects
in the drawing.
These characteristics make vector-based
applications ideal forillustrations and
they are resolution independent. As a
result, the image quality of a drawing is
a high quality resolution

7. RESOLUTION
The degree of sharpness of a computer
generated image as measured by the
numberof dots perlinearinch in a
hard copy printout orthe numberof
pixels across and down on a display
screen.

8. BITMAP IMAGE
In computergraphics, a bitmap or
pixmap is a file format used to store
digital images. The termbitmap
comes fromthe computer
programming terminology, meaning
just a map of bits, a spatially mapped
array of bits(pixels)

9. PIXELS
In digital imaging, a pixel orpel is the
smallest addressable element in a
display device(screen)
LCDpixels are manufactured in a two
dimensional grid and are often
represented using dots orsquares
A megapixel = o ne m illio n pixe ls
A camera with 2.0 megapixels = two
million pixels

10. An example showing an image with a portion
greatly enlarged, in which the individual pixels
are rendered as little squares and can easily be
seen
