Adobe Acrobat .PDF Raster Export Options Dialog

Adobe Acrobat Portable Document Format .PDF is a file format used for document exchange. PDF is used for representing two-dimensional documents. PDF was created by Adobe Systems.

Use a raster .PDF to export the entire Surfer project as an image in .PDF format. Use the Export Options dialog to specify the Image size in pixels, Dots per inch, Color format, and to Maintain aspect ratio. The higher resolution image you select, the larger the .PDF file will be. All images, lines, text, maps, etc. will be exported into the single image object in the raster .PDF file. Raster objects lose quality at low resolutions or when you zoom in. The raster .PDF output will look exactly like your original project.

GeoPDF

When a map with a defined coordinate system is exported to a Raster PDF file format, the georeference options for the GeoPDF are changed on the Scaling and Spatial References pages in the Export Options dialog. The Internal file format option must be checked on the Spatial References page to create the GeoPDF.

An add-on, such as TerraGo toolbar, may be needed to view the GeoPDF options in Adobe's Acrobat or PDF Reader programs. The map layer and map must have an assigned coordinate system in Surfer prior to the export.

Export Options Dialog (for Raster PDF)

When using the File | Export command to export to a PDF (Raster) file, the Export Options dialog allows you to specify the Size and Color options and Spatial Reference options. In addition, the Raster PDF Options page is available to compress the image in the .PDF file.

Specify PDF specific export options on the Raster PDF Options page.

Compress Images

Check the box next to Compress images to apply .PDF compression to the images in the .PDF file. This produces smaller raster .PDF files with no loss in quality. When this option is unchecked, .PDF files will be larger.

Page Options

The Page Options section controls the page size in the exported .PDF file. Select the Use application page size (if available) to use the paper size defined in the Page Setup dialog. If Fit page around exported objects is selected, the page size in the .PDF file will be only as large as the objects being exported.

When the Use application page size (if available) is selected and objects extend beyond the page defined in the Page Setup dialog, the objects are clipped and not displayed in the PDF file.
