Raster Image vs. Vector Image

Raster Image also known as bitmap image is 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. When you enlarge the raster image you can clearly see each individual square dot of color.

Bitmap images are resolution dependent which means that it's difficult to increase or decrease their size without sacrificing a degree of image quality. Resolution refers to the number of pixels in an image and is usually stated as dpi (dots per inch).

Common bitmap formats include:
• PICT (Macintosh)
• PSD (Adobe Photoshop)

Vector Image is made up of many individual, scalable objects. These objects are defined by mathematical equations so they always render at the highest quality. Objects may consist of lines, curves, and shapes with editable attributes such as color, fill, and outline. Changing the attributes of a vector object does not effect the object itself.

Vector images are resolution independent. You can increase and decrease the size of vector images to any degree you want and your lines will remain crisp and sharp.

Common vector formats include:
• AI (Adobe Illustrator)
• CDR (CorelDRAW)
• EPS (encapsulated postscript)
• CMX (Corel Exchange)
• CGM Computer Graphics Metafile
• WMF Windows Metafile
