Specify Vector PDF options in the 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. The vector .PDF export supports solid pattern, windows stock, and image patterns.
Use a vector .PDF to export the vector objects in the project (lines and text) as vector objects in the PDF. This makes the objects clear and sharp. Vector objects do not loose quality when you zoom in. It doesn't matter how much you zoom in, the line and text will always look crisp. The images in your project will also export as images in the vector .PDF. Vector .PDF files are smaller than Raster .PDF files and are usually higher quality.
Vector .PDF export exports all layers to the .PDF file.
Objects that are transparent or partially transparent in Didger are exported with the transparency enabled in the .PDF. The only exception is objects filled with a stock fill pattern. In this case, the object's Foreground opacity and Background opacity are averaged and the object is exported with a single average opacity.
When a map with a defined coordinate system is exported to a vector PDF file format, a GeoPDF file is created automatically.
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 Didger prior to the export.
When using the File | Export command to export to a vector .PDF file, the Export Options dialog allows you to specify the PDF options.

Options dialog.
The Resize embedded images to less than option specifies the size in megabites that an embedding image is resized to during export. Enter a value in the MB box. If an exported image exceeds this size, its resolution will be reduced so it doesn’t exceed the designated maximum size. Increase this value to get better looking images at the expense of larger export files. The default value of Resize embedded images to less than option is 10 MB.
As long as there is no shear, perspective, or clipping, PDF text entities will be exported as text. This means that the PDF text entities will be sized and oriented similar to the text objects in the application document. When shear, perspective, or clipping occur, the text is exported as solid polygons. Shear occurs when the character glyphs are not perpendicular to the text baseline. Perspective occurs when the height of glyphs in the text string are not all the same, as in a 3-D view where the glyphs are smaller the farther they are from the observer. Clipping occurs when part of the text object is partially inside and partially outside the map limits.
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 Print 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 Print Setup dialog, the objects are clipped and not displayed in the PDF file.
The Compression options section contains options that can make the PDF file size smaller.
Check the box next to Compress images to apply .PDF compression to the images in the .PDF file. This produces smaller vector .PDF files with no loss in quality. When this option is unchecked, .PDF files will be larger.
Check the box next to Compress pages to apply .PDF compression to the entire page stream. This produces significantly smaller vector .PDF files with no loss in quality. When this option is unchecked, .PDF files will be larger.
Check the box next to Embed fonts (when available) to store the fonts inside the .PDF file. This produces a larger vector .PDF file, but the font in the .PDF file will exactly match the font in the Didger file. When this option is unchecked, the .PDF file will be smaller, but the text may not appear the same in the .PDF file as it does in the Didger file. Some fonts cannot be embedded. A different font is substituted when this is the case.
Click the Defaults button to return the options to the default values.
