![]() If you try to enlarge a raster image beyond the original resolution it was made at, the computer has to basically guess what colors the new pixels should be, giving the edges a jagged, muddy “pixelated” look.Ī good example of a raster is a photograph. Nothing is truly smooth or solid, we just interact with them at a comfortable distance, or resolution, to make them appear connected. Lines and fills are rendered by plotting a finite number, the dots-per-inch, of individual points in space. Raster images are more like atoms - not truly solid. No matter how big or small you make a vector image, because the strokes and fills of are made of infinitely connected points they will always look the same at any size or viewing distance.Ī good example of a vector is a type font. For example, (x 2 + y 2 – 1) 3 = x 2 y 3 describes the outline of a heart. Vector images are smooth because the geometry of shapes are described by mathematical equations. ![]() Here’s my best attempt, and I’m posting it with a request to please pick it apart to help me improve it. I would consider making your own quick fact sheet you can attach to emails that contains information similar to this: ![]() If the PDF looks "right" they're going to call it a day. I pixel peep my exports and look at separations, that's why I noticed it. I mention this, because little things like this can cause rasterization effects on export whether the designer knows it or not. Once I eliminated the stroke everything exported as a vector. After doing that and reading another post on the Affinity forums, I found the issue was a vector mask I was using had a stroke applied to it that wasn't visible. I figured one element had to be causing it, so I started digging through my layers to try to find the culprit. Affinity states that if any vectors get rasterized on export, its because of a limitation with the Adobe PDF standard. I was creating a logo the other day and could not figure out why part of it was rasterizing on export, regardless of what vector format I output to. I use Adobe at work and the Affinity suite at home (Designer, Photo, Publisher). So, just giving you a heads-up with an issue I just ran into.
