Getting Started with PDFix SDK

PDFix SDK is a cross-platform PDF processing tool that offers multiple integration options. The Command-Line Interface (PDFix CLI) provides a quick and easy way to add PDF processing functionality to various workflows without writing code.

Developers can leverage the SDK with different programming languages for full control over PDF documents.

Before getting started, check the system requirements to ensure compatibility with your system.

PDFix offers straightforward, rapid, and automated PDF processing via the command-line interface:

$ ./pdfix_app make-accessible -i test.pdf -o output.pdf

For additional CLI options, refer to the PDFix SDK Command-Line Interface documentation. The CLI application is included in the downloadable package available on the PDFix website.

Multi-Threaded Environments

PDFix SDK operates in a single-threaded manner, allowing only one API method to run at a time within a single process. Any additional method calls from other threads will be queued until the current operation finishes.

For parallel processing, use separate processes rather than threads.
