MAPublisher has the ability to export the entire working artboard or document as an image that can include georeferencing. This is particularly useful when working with spatial vector data and a suitable georeferenced image of it is required. MAPublisher can export selected images as TIFF, PNG or JPEG with a choice of reference file formats, including GeoTIFF.
Using Export Document To Image
In the Export Document To Image dialogue box, choose a source to export as the image. The source can either be a specific artboard or all art in the document.
In the Destination section, choose an image format, colour mode and filename. The Image format drop-down lists several types: TIFF, BigTIFF, PNG, and JPEG. By default, the JPEG image quality setting is 75, the PNG compression level setting is 6, and TIFF uses LZW compression. The Colour mode drop-down list offers RGB, Grayscale and CMYK. The PNG format does not allow for CMYK colour mode because it is primarily used for on-screen display purposes. TIFF and PNG images allow for transparency.
In the Options section, choose an appropriate level of resolution and option to include georeferencing. The Resolution setting includes 36, 72, 150, 300, 600 ppi, or a custom value. A high resolution of 300 ppi is more suitable for print (larger file size), while a low resolution of 72 ppi is appropriate for on-screen display (smaller file size). Anti-aliasing improves image quality; choose between Art Optimized and Type Optimized. Enable the Include georeferencing option and choose a MAP View and reference format: World, Blue Marble Reference, MapInfo Table, ER Mapper ERS, or GeoTIFF. For reference formats that do not store coordinate system information, enable the Export coordinate system option to include a WKT or PRJ reference file. The GeoTIFF reference format is only available when the image format is set to TIFF. Reference files are saved to the same location as the image file.
Spot colour in the working document will not be maintained in the exported image.
BigTIFF extends the original TIFF file format specification to support 64-bit (for images larger than 4 GB). It is the result of work by a variety of parties including Adobe Systems. BigTIFF is expected to be useful for people and vendors that are confronted with unusually large images and still seek to use an open, simple, and extendable format. BigTIFF is not yet an official standard and is still awaiting final approval.
ICC Profiles will be embedded when Exporting Documents as TIFF files. If an Adobe Illustrator document is in CMYK colour space, its colour profile will be embedded in the TIFF if the exported TIFF’s colour mode is also set to CMYK.
