In other words, we respect the pixel grid to make sure our symbols do not appear 'fuzzy' on standard-resolution displays.Īll our symbols are developed as resolution-independent scalable vector graphics (SVGs). We create our artwork to be as 'pixel-perfect' as possible. When optimizing artwork at 14 and 22px, every pixel counts. Two sizes have been designed for each symbol for greater cartographic flexibility: 14 and 22px.Supporting black and white versions of each assures we can render them clearly on top of a wide range of base maps and placemarkers.As a result, we've eliminated the bounding box for our symbols. Web map symbols need a slim profile to reduce bulk at multiple zoom levels, render well within placemarkers, and not interfere with other classes of information.You may also need to ungroup the symbol (often a few times) to be able to access all elements in the symbol.We considered the following factors when adapting print map symbols for use on our web maps: Illustrator: Right click > Break Link to Symbol.When opening a symbol from the SVG or AI palette versions, or via the image library import in the online diagrammer, you need to break the link to the symbol before it can be edited. NOTE: If you open the illustrator files directly, they will appear blank. The symbols are accessed via Window > Symbol Libraries > IAN Symbols. Simply open each file directly in your graphics software. The symbols in this version are raster which is great for quick use in documents, but they are not easily editable or scalable. The zip package can be unzipped anywhere. * can be imported into MS PowerPoint and Word, or edited with Adobe Photoshop etc * requires vector software such as Inkscape (free), Adobe Illustrator or CorelDraw If you are not familiar with Illustrator symbol palettes, see the 'Accessing the Libraries' section below.You may need to restart Illustrator for it to load the libraries.If you try to open these files directly, they will appear blank.Prior to CS4, there was no language folder inside the Presets folder.* requires Adobe Illustrator CS2 or betterĬ:/Program Files/Adobe/Illustrator X/Presets//SymbolsĪpplications/Adobe Illustrator X/Presets//Symbols
