TWO MAIN TYPES OF GRAPHICS

1. Bitmap

2. Vector

VECTOR IMAGES

• Vector images are made up of many individual, scalable objects.

• These objects are defined by mathematical equations rather than painted pixels.

• Objects cab be lines, shapes, and\ or text with properties the designer can alter such as color, outline, effects. Etc.

VECTOR FACTS

• Vector-based images are resolution (size) independent.

• You can increase and decrease the size of vector images to any degree and your lines will remain crisp and sharp, both on screen and in print.

• They do not pixelate or get blurry when you change the size!

VECTORS - RESOLUTION INDEPENDENT

VECTOR FACTS

Common vector file formats include:

• AI (Adobe Illustrator)

• CDR (CorelDraw)

Popular vector drawing programs include:

• Adobe Illustrator

• CorelDraw

• AutoCAD

BITMAP IMAGES

• Bitmap images (also known as raster images) are made up of pixels in a grid. Pixels are tiny dots of individual color that make up what you see on your screen.

• Bitmaps are painted pixels!

• All these tiny dots of color come

together to form the images you see.

BITMAP FACTS

• Bitmap images are resolution (size) dependent.

• Resolution refers to the number of pixels in an image and is usually stated as dpi (dots per

inch) or ppi (pixels per inch).

• Because bitmaps are resolution dependent, it's difficult to increase or decrease their size without sacrificing a degree of image quality.

• They pixelate or get blurry when you attempt to change the size!

BITMAPS - RESOLUTION DEPENDENT

BITMAP FACTSCommon bitmap file formats include: •BMP•GIF•JPEG\ JPG•PNG•TIFF

Popular bitmap editing programs include: •Microsoft Paint•Adobe Photoshop•Corel Photo-Paint
