Creating Images and Graphics

This is the original PNG image. When zoomed in, you can clearly see that the image is blocky and individual pixels are more visible.

This is the zoomed in Vector file of the same image. The image is much more crisp, and the detail of the drawing has barely been modified; little to no pixels are visible and the image is not blocky. However the outlines and colours are a little messy and misplaced.

This is the original PNG image. The image is not as heavily pixelated/blocky as the first one, however the outlines are fuzzy and blurry.

This is the zoomed in Vector file of the same image. The lines are almost perfect, and they are smooth and crisp with almost no visible pixels. 


This blog post shows the differences between PNG/JPEG images and Vector graphics when zoomed in, and how Vector graphics improve image quality. Overall, I learned that vector graphics are better than the default PNG/JPEG image files for quality, and are very useful for logos, illustrations, etc.
Although, PNG files are useful because they offer transparency support and much less quality is lost. JPEG files are also useful because they can be compressed to very small sizes, although quality is often lost.
