CorelDRAW 10 is a very powerful graphic design package. With that power, comes a fairly complex design environment and an almost infinite combination of tools and effects. In this book you will learn to work with most these tools and effects. Computer graphics programs are classified in two categories. The first type graphic programs are bitmapped programs like Adobe Photoshop, etc. where in the images are created in the form of bitmap. The other set of graphic programs use vector graphics where the graphics are composed of mathematical curves. CorelDRAW belong to the category of vector graphic program. In addition, CorelDRAW 10 comes packaged with CorelDRAW PAINT, a powerful program for creating and editing bitmap images. Before you start creating your own graphic images, you need to understand a few basic concepts about what CorelDRAW does both on your screen and behind the scenes. A basic understanding of the unique way CorelDRAW creates images will help you design images and transform those images to print copy or web page output more effectively. CorelDRAW is a vector-based PROGRAM, which means that it creates and handles images as mathematically defined vectors. Vectors are objects with both (angles, curvature, and so on). The files that store CorelDRAW images consist of lists of lines, with information on their location, direction, length, color, and curves. Defining images as a series of vectors is a more efficient way to work with them than defining images as bit map or a huge number of individual pixels. This is because even a simple object might have thousands of pixels, each individually defined, whereas the same image might be defined more rationally as a small number of curve segments. CorelDRAW 10 vector image files are often smaller than comparable bitmapped image files. A bit map file of 2724 KB will be just of 112 KB in CorelDRAW. In addition to creating more compact files, CorelDRAW’s vector-based images have other important advantages. You can easily resize a CorelDRAW image to a thumbnail sketch or icon or a billboard-sized graphic. When you change the size of a bitmap image, you lose quality because the number of dots, or pixels, remain the same even as the illustration is enlarged. That is not the case with CorelDRAW’s curve-based illustration. However, graphic designers have to work with bitmaps, especially while working with images that appear in, or as Web pages. Popular Web browsers cannot interpret images in CorelDRAW’s native format. The relatively low resolution of computer monitors (generally 72 dots per inch) tends to negate the advantages of creating vector-based images. The relatively small, low-resolution images seen on Web tend to make curves jagged and grainy regardless of how smooth and high-resolution the original image. CorelDRAW give you the capability of creating almost any graphic image file you will ever need. Most of the images are still destined for hard copy, and CorelDRAW’S vector-based images are best for printed output. Corel’s vector based tools provide the most powerful range of features for designing images. CorelDRAW can then easily translate those images into bitmap formats. In fact, CorelDRAW has a powerful capacity to transform objects into both of the Web-compatible bitmap file format: i.e. GIF and JPEG. Source.
