Most of the code samples in APDFL are designed to demonstrate how an API works by completing a simple programming task.
We assume a basic level of technical understanding of the PDF file format, individual sample category directory markdown files go into more details.
Many of these sample programs automatically generate an output file or set of files. These output files, generally PDF or graphics files (JPG or BMP), are stored in the directory where the application has been run. If you run a sample program a second or third time, it will overwrite any output files that were created and stored earlier. However, if you run a sample program, generate a PDF output file, and then open that PDF file and try to run that sample program again, you will see an error message. The program will not be able to overwrite an existing output file if that file is currently open in another program.
(Note: that the Forms Extension product and samples are available by talking to Datalogics Sales.)
