1 00:00:00,760 --> 00:00:03,360 [Deep Dive] 2 00:00:03,360 --> 00:00:05,990 [Introduction to Illustrator: Vecto vs. Raster Graphics with Mat Helme] 3 00:00:06,430 --> 00:00:09,830 As I've mentioned earlier, Illustrator is vector base application 4 00:00:09,830 --> 00:00:12,970 whereas Photoshop is a raster base application. 5 00:00:12,970 --> 00:00:16,020 But what exactly is a vector-based application 6 00:00:16,020 --> 00:00:18,950 and how is it different than a raster-based application? 7 00:00:18,950 --> 00:00:20,040 Let's take a look. 8 00:00:23,380 --> 00:00:27,130 Raster graphics are constructed of individual pixels. 9 00:00:27,960 --> 00:00:32,659 As we viewed the image at a 100%, we're unable to detect these pixels. 10 00:00:32,659 --> 00:00:35,460 The colors seem to blend very nicely together. 11 00:00:35,880 --> 00:00:38,230 However, when we zoom in on our image, 12 00:00:38,230 --> 00:00:42,850 you'll notice the individual pixels or squares with solid colors. 13 00:00:43,470 --> 00:00:45,780 This is why we need to worry about resolution 14 00:00:45,780 --> 00:00:47,640 when dealing with raster images. 15 00:00:48,330 --> 00:00:52,800 We can never increase the resolution of an image without losing visual quality. 16 00:00:53,860 --> 00:00:57,440 We can only decrease the resolution and maintain quality. 17 00:00:57,980 --> 00:01:00,090 Vector graphics are quite different. 18 00:01:01,170 --> 00:01:03,790 Vector graphics are shapes or objects 19 00:01:03,790 --> 00:01:06,290 comprised of anchor points and paths. 20 00:01:07,230 --> 00:01:12,000 Whether we're viewing an image at 100% or 2000%, 21 00:01:12,000 --> 00:01:14,040 we never lose clarity. 22 00:01:14,040 --> 00:01:18,120 Since they are based on points and paths or mathematical equations, 23 00:01:18,120 --> 00:01:21,210 they are consistently rendered depending on our view. 24 00:01:22,250 --> 00:01:24,190 This allows us to never deal with resolution. 25 00:01:24,190 --> 00:01:26,190 Let me show you how. 26 00:01:29,330 --> 00:01:31,290 As technology advances, 27 00:01:31,290 --> 00:01:34,410 we are presented with more and more devices to design for. 28 00:01:34,930 --> 00:01:39,350 Until recently, the newer devices have different graphical resolutions 29 00:01:39,350 --> 00:01:43,780 varying from 72 PPI to 300 PPI. 30 00:01:43,830 --> 00:01:46,720 PPI stands for pixels per inch. 31 00:01:47,200 --> 00:01:50,190 This is causing us to support multiple image sets 32 00:01:50,190 --> 00:01:52,390 when dealing with raster images. 33 00:01:52,930 --> 00:01:54,960 However, if we use vector graphics, 34 00:01:54,960 --> 00:01:59,120 we only need to supply one image as its scalable 35 00:01:59,120 --> 00:02:03,280 and never loses clarity no matter what the screen resolution is. 36 00:02:04,200 --> 00:02:06,360 Symbol fonts are a great example. 37 00:02:06,860 --> 00:02:09,949 When we increase the size of symbol fonts, 38 00:02:09,949 --> 00:02:15,140 they consistently re-render, always displaying a solid crisp graphic.
