Introduction of Corel Draw 12
Corel
draw is graphics application that is used to design advertisement, logo, cads,
broachers, newsletters, banners, images, and so on, for print or for web.
An
artwork developed in CorelDraw is referred as a drawing. Each component created
in a drawing such as line, text, curve, symbols or image is referred as an
object. Each object in a drawing stores its own attributes, such as shape,
size, position, and color. The drawings can be modified without affecting
drawing quality.
Types of Digital Images:
Computer
graphics comes in two main types
Raster Images (Photo Realistic):
Raster
images also known as Bit-mapped images are made up of a mosaic of picture
elements, called Pixels. A pixel is the smallest unit of composition in an image.
When raster images stored, the information contained in each pixel is stored
separately, which increases the file size?
When
raster images enlarged, their edges appear rough and jagged.
Raster
images are realistic and manipulate-able (each pixel can be edited on an
individual basis)
Vector
Images:
The images consist of lines
and curves that are defined mathematical objects are called vector images.
Vector images can alter to large size without making their edges rough or
jagged. Vector images are ideal for web pages because they are small in size,
and so they download faster than raster images.
Vector based images commonly
used in Computer Aided Drawings (CAD), and digital drawing software.
Corel Draw an Overview:
Corel DRAW is a vector graphics editor developed and marketed by Corel Corporation of Ottawa, Canada. It is also the
name of Corel's Graphics Suite
In 1997, Corel hired software engineers Michel
Bouillon and Pat Beirne to develop a vector-based illustration program to
bundle with their desktop publishing systems. That program, CorelDRAW, was
initially released in 1999. CorelDRAW 1.x and 2.x runs under Windows 2.x and
3.0. CorelDRAW 3.0 came into its own with Microsoft's release of Windows 3.1.

Grid:
The
grid is a series of intersecting dashed lines or dots that you can use to
precisely align and position objects in the drawing window.
The
distance between the grid lines or dots can be set by specifying the frequency
or spacing.
Frequency:
Frequency
refers to the number of lines or dots that display between each horizontal and
vertical unit. Spacing refers to the exact distance between each line or dot.
High frequency values or low spacing values can help you align and position
objects more precisely.
To
set the distance between the grid lines
- Click View à Grid and ruler
setup.
- Enable one of the following options:
- Frequency — specifies grid spacing as the number of lines per unit of measure
- Spacing — specifies grid spacing as the distance between each grid line
- Type values in the following boxes:
Snap to Grid:
To force an object that is being drawn or moved to
align automatically to a point on the grid, a guideline, or another object.
