Ok so here’s the thing: yes, pixel is a unit of measure. Problem is, a lot of people tend to use “pixel” interchangeably with “point,” or worse, they disregard the pixel size of a “rasterized” image altogether.
What’s “rasterized,” you ask? Rasterized simply means an image “made out of pixels.” This pretty much always means an image, as opposed to type (words and sentences), or “vector” images. Yes a rasterized image can have type in it, but it won’t be type you can independently alter just by changing font size or adding or deleting a word. In a rasterized file, the type has basically become a picture of the word or words. Vector art is created using mathematics to describe its appearance, which your computer then interprets and displays, as opposed to raster images. As a result, vector art can be displayed or printed at any size without changing its quality or characteristics at all, as opposed to rasterized images. And herein lies the subject of this missive.
