In Illustrator CC (2015 release), there have been many improvements and enhancements to Creative Cloud Libraries, Graphics are now linked so that when they’re changed, you and your team members have the option of updating them across any Illustrator CC, Photoshop® CC, or InDesign® CC projects where they’re used. Adobe® Illustrator® CC is the industry-standard illustration application for print, multimedia, and online graphics. Whether you are a designer or a technical illustrator producing artwork for print publishing, an artist producing multimedia graphics, or a creator of web pages or online content, Adobe Illustrator offers you the tools you need to get professional-quality results.
In Illustrator, you primarily create and work with vector graphics (sometimes called vector shapes or vector objects). Vector graphics are made up of lines and curves defined by mathematical objects called vectors. You can freely move or modify vector graphics without losing detail or clarity because they are resolutionindependent. In other words, vector graphics maintain crisp edges when resized, printed to a PostScript printer, saved in a PDF file, or imported into a vector-based graphics application. As a result, vector graphics are the best choice for artwork, such as logos, that will be used at various sizes and in various output media.
Illustrator also allows you to incorporate bitmap images—technically called raster images—that use a rectangular grid of picture elements (pixels) to represent the visual. Each pixel is assigned a specific location and color value. Raster images can be created in a program like Adobe Photoshop®.
The Graphics Processing Unit (GPU), found on video cards and as part of display systems, is a specialized processor that can rapidly execute commands for manipulating and displaying images. GPU-accelerated computing offers faster performance across a broad range of design, animation, and video applications. The GPU Performance in Illustrator feature has a preview mode called GPU Preview, which enables rendering of Illustrator artwork on the graphics processor. This feature is available on Windows computers that have an NVIDIA GPU installed and compatible Mac OS computers. This feature is turned on by default for RGB and CMYK documents, and options can be accessed in Preferences by clicking the GPU Performance icon in the Application bar.

An Introduction to Illustrator's Color Tools
Saving content for the web Using Illustrator CC,
you can save your artwork for the web using a variety of methods and formats. If you need web images for use in a website or an onscreen presentation, you can use the File > Save For Web command. Images can be saved in several file formats, such as GIF, JPEG, and PNG. These three formats are optimized for use on the web and are compatible with most browsers, yet each has different capabilities.
If you are building a website or want to hand off content to a developer, you can transform the visual designs in Illustrator to CSS styles using the CSS Properties panel (Window > CSS Properties) or File > Export command. Illustrator allows you to easily export CSS or copy and paste CSS from Illustrator into your HTML editor. You can also export Scalable Vector Graphics (SVG) using a variety of methods.
Before you save content for the web, it’s important to understand the pixel grid in Illustrator. It’s critical that raster images look sharp, especially standard web graphics at 72 pixels per inch (PPI) resolution. To enable web designers to create pixel-accurate designs, you can align artwork to the pixel grid. The pixel grid is a grid of 72 squares per inch, vertically and horizontally, that is viewable when you zoom to 600% or higher with Pixel Preview mode enabled (View > Pixel Preview).
When the pixel-aligned property is enabled for an object, all the horizontal and vertical segments in the object get aligned to the pixel grid, which makes strokes appear especially crisp. When you create a new document, you can set the Align New Objects To Pixel Grid option at the document level. This makes all artwork that can be aligned to the pixel grid (this does not include Live Shapes such as rectangles) align to it automatically.
Saving artwork as SVG
SVG (Scalable Vector Graphics) are used to define vector-based graphics for the web that won’t lose quality if they are zoomed or resized, such as a logo. They are a vector format that describes images as shapes, paths, text, and filter effects. The resulting files are compact and provide high-quality graphics on the web, in print, and even on resource-constrained, handheld devices. Most major modern web browsers—such as Mozilla Firefox, Internet Explorer 9+, Google Chrome, Opera, and Safari—have at least some support for viewing SVG. Illustrator allows you to select vector artwork, choose Edit > Copy, and then simply paste the SVG code that it generates into HTML in an HTML editor, or you can export or save as an SVG (.svg) file. In this section, you’ll export as SVG (.svg) and explore the SVG export options using the File > Export command.
