The following environment variable must specify a path to the PDF component resource files:

• LD_LIBRARY_PATH environment variable. For example:

  	Copy Code
  IMAGE_GEAR_PDF_RESOURCE_PATH=$HOME/Accusoft/ImageGear18/Resource/PDF/ IMAGE_GEAR_PS_RESOURCE_PATH=$HOME/Accusoft/ImageGear18/Resource/PS/ IMAGE_GEAR_HOST_FONT_PATH=$HOME/Accusoft/ImageGear18/Resource/PS/Fonts/

See the PDF Component API Function Reference for more ImageGear PDF initialization details.

The PostScript Normalizer library of the ImageGear Professional Linux 32-bit PDF component does use text relocations, which is restricted under SELinux (RHEL, CentOS, and some other distributions), and may result in failure to load the PDF component. This can be countered by permitting text relocations specifically to Normalizer, without disabling SELinux in general:     # /usr/sbin/semanage fcontext -a -t textrel_shlib_t '/home/user/Accusoft/ImageGear18/bin/libDL100nserver.so'     # /sbin/restorecon -v /home/user/Accusoft/ImageGear18/bin/libDL100nserver.so where /home/user/Accusoft/ImageGear18 is the actual path to your ImageGear Professional installation.
