It's almost impossible to discuss graphics software without first establishing an understanding of the differences between the two major 2D graphic types: bitmap and vector images. This is an important lesson and often a tough one to grasp. If you work with graphics at all, it's bound to come up, so it's an important concept to understand. Let's start by talking about the more common type: bitmap images. Facts About Bitmap Images Bitmap images (also known as raster images) are made up of pixels in a grid.
Pixels are picture elements; tiny dots of individual color that make up what you see on your screen. All these tiny dots of color come together to form the images you see. To illustrate this, let's take a look at a typical desktop icon such as the one shown in the image here. Bitmap images are resolution dependent. Bitmap images are displayed on your computer screen at screen resolution: approximately 100 ppi. Bitmap images in general do not inherently support transparency. Vector Images - Two Types of Graphics - Vector and Bitmap. Continued from Page 1: About Bitmap Images Although not as commonly used as bitmap graphics, vector graphics have a lot of virtues. Let's explore them now.
Facts About Vector Images Vector images are made up of many individual, scalable objects. These objects are defined by mathematical equations rather than pixels, so they always render at the highest quality. Changing the attributes of a vector object does not effect the object itself. Because they're scalable, vector-based images are resolution independent. Another advantage of vector images is that they're not restricted to a rectangular shape like bitmaps. Vector images have many advantages, but the primary disadvantage is that they're unsuitable for producing photo-realistic imagery. Vector images primarily originate from software. The most common reason for wanting to convert a vector to a bitmap would be for use on the Web. Popular vector drawing programs are:• Adobe Illustrator• CorelDRAW• Xara Xtreme• Serif DrawPlus• Inkscape.
