In contrast to pixel-base raster images, vector images are composed of lines, fill colors and instruction on how the graphic should be displayed. Even after vector graphics have been rendered and packed into a file, you can go back and edit the file's lines and colors. If you're working with vector graphics in Illustrator, you'll need to export your project in a vector image format if you think you might have to make adjustments to the graphic later on.
Launch Adobe Illustrator. Select the "Open" option at Illustrator's welcome screen to load the project you wish to export into a vector graphics format.
Click on the "File" heading in Illustrator's main menu. Click on the "Export" option in the menu that appears below the "File" heading.
Click on the "Save As Type" menu box when the "Export" menu appears. Click on the menu box's "Flash (SWF)" option if you intend to use the vector image in a flash project. Otherwise, select the "Enhanced Metafile (EMF)" option from the menu box.
Browse through the "Export" menu's folder tree to select an output folder for your vector image. Type a name for the image into the "Export" menu's "File name" field.
Click on the "Export" menu's "Save" button to turn your Illustrator project into a vector image file.
