They are commonly used for distributing documents on the web, and the format is now an official ISO standard for document interchange. PDF files are designed to be consistently viewable and printable across different platforms. ![]() JPEGs can be generated with an accompanying world file for use as georeferenced raster data. Thus, PNG is usually a superior format for map images. However, the JPEG compression algorithm is lossy and is not recommended for many map images, as line drawings and text or iconic graphics become blurred by compression artifacts. They support 24-bit color and have been a popular choice for use on the web because JPEG file size is often substantially smaller than many other image formats. GIFs can be generated with an accompanying world file for use as georeferenced raster data. Like PNG, GIF files also have the ability to define a transparent color. GIF files cannot contain more than 256 colors (8 bits per pixel), which, along with optional lossless RLE or LZW compression, makes them smaller than other file formats. GIF is a legacy raster format for use on the web. EPS files support font embedding and can define colors in CMYK or RGB values. EPS files can be edited in many drawing applications or placed as a graphic in most page layout applications. PostScript is the publishing industry standard for high-end graphics files, cartography, and printing. However, since EMF does not support font embedding and is exclusively a Windows format, it is not commonly used as an interchange format between users.ĮPS files use the PostScript page description language to describe vector and raster objects. BMP images are typically much larger than formats such as JPEG or PNG.ĮMF files are useful for embedding in Windows documents because the vector portions of the EMF can be resized without loss of quality. ![]() BMPs can store pixel data at several bit depths and can be compressed using the lossless RLE method. Once opened in Illustrator, the file can be used for high-end graphic design or map finishing workflows and migrated across the other Adobe Creative Cloud applications.īMP files are native Windows raster images. With the extension, vector and raster map content is converted into editable, layered artwork for an improved editing experience in Adobe Illustrator. ![]() AIX files are used with the ArcGIS Maps for Adobe Creative Cloud extension.
