When you save a document PDF Nomad saves a new version of the PDF file you opened, incorporating the changes you made. There are options, however, to export other variations of the document:
You can explode PDF documents into smaller documents consisting of individual pages from the original, or into multiple documents each containing smaller groups of pages from the original. The following options are available when exploding:
This option will split create two PDF files, one with all even pages of the original document, and the other with all odd pages of the original document. A filter can be applied to both documents as they are created.
This option splits the document’s pages into bitmapped graphics files. One file per page. Pages can be exported to TIFF, BMP, GIF, JPEG, PNG or JPEG2000, optionally with a transparent background (instead of the page color, which is usually white), at the specified pixel resolution, which defaults to 72. (Pages that have a painted (white) background cannot be made transparent.)
Choose the output resolution depending on the intended use of the images. If the images are going to be shown on-screen only you probably want to keep them at 72 dpi. (Or, for high resolution screens like the iPhone 4 Retina display, 144 dpi). If the images will be printed, you may want to specify at least 300 dpi. (This will dramatically increase the file size of the resulting image files.)
A filter can be applied when the bitmap files are created. For instance, you could create sepia tinted monochrome versions of each page.
This option exports the textual contents of the document as an RTF document. Note that only the text on the pages will be exported. Annotation text of any kind will not be included.
This option exports selected text (or all document text if no text is selected) to an AIFF audio file.
Where the options listed above operate on the complete set of pages contained in a PDF document, this option will export only the pages that are selected in the page list at the time the export selection command is issued. This offers a convenient way to export a subset of pages from the entire document, as a single PDF document. A filter can be applied during the export.
