The RTPDF-32 library is a subset of the Amyuni PDF libraries that can run under the RTOS-32 operating system. RTPDF-32 is provided as a single 32-bit library file named RTPDF-32.lib and 2 header files.

RTPDF-32.lib is compatible with Visual Studio 2015 and higher. The header file can be included into C or C++ source files.

In order to reduce the memory footprint and increase performance, PDF instructions are generated on the fly whenever library calls are made. RTPDF-32 does not provide any methods for storing the PDF data to memory, disk or sending the data through a communication channel. The calling application implements callback functions to receive the data from the library and store or send the PDF data.
