if selected, will take you to a full-page view of Page 2. However, Page 2’s "Link to
page 1," if selected, will zoom in on its Page 1 target note to fill the entire screen.

Finally, the third page demonstrates two methods of visually cueing the reader to
embedded hyperlinks: boxing the hyperlink area with an outline rule, or generating
text of a different color. In either case, clicking on the links should trigger a jump to
the Datalogics website at http://www.datalogics.com.
memFiles
This sample demonstrates use of the Datalogics Files-in-Memory file system. Using
this filesystem, a DLI user can create ASFile objects from a memory buffer ,
enabling creation of images from memory such as database blobs (Binary Large
OBjects). The filesystem also allows the user to write PDF files to memory buffers,
which can then be retrieved, written to other files or manipulated in various ways.
Temporary files are also written to the Files-in-Memory filesystem, if it is active at the
time the temporary file is opened. This usually occurs when a document is created.
MultiDoc
This sample controls the generation of multiple documents from a single run of the
application. It has two required arguments:
• Argument 1 must be the number of documents to produce.
• Argument 2 must be the number of pages per document to produce.
Several additional, optional arguments may also be used to vary the output as desired,
such as PSTOUT or PDFOUT keywords to generate PostScript or PDF output
respectively. (This sample is mainly intended to demonstrate program operation, not
text output.) Other command-line arguments can also be given in order to test output
variations or application performance. Run the sample with no command-line
arguments for a short usage message; see the source code file MultiDoc.c for more
details.
