What are the advantages and disadvantages of object-based graphics versus pixel-based graphics?

There are a couple of distinct advantages and disadvantages for using either type of images. For object-based ones (also called vector graphics), the pros include scalability (or the resizing of an image) without having to worry about jagged edges due to pixel enlargement/shrinking, its relatively smaller file size than its counterpart format and its ability to remain at its best graphical quality without any tweaking or file converting. Some of the disadvantages are the time-consuming nature of creating the image(s) (personally, I can relate to this), the more expenses needed to produce the image and the inability to edit or take a photo as a vector image.

For pixel-based graphics (also called raster), the format is useful for editing the quality (i.e. color) and changing the property (i.e. size) of photos, being precise and detailed as images are made up of an infinitesimal amount of squares (allowing for color changes and variations in any given area, small or big in the photo) and lastly, the ability to work well and load in almost any program. Some of the drawbacks of the graphics are the large sizes (where larger files slow down edibility), grain and distortion caused by missing pixels that are filled out automatically (when manipulating a photo’s boundaries) and the RGB color scheme that gets lost upon print (one would have to covert to CMYK in this case).
