Example

This example will reset the current JPEG2000 options to their default values.

L_INT LFileSettings__GetDefaultJ2KOptionsExample() 
{
   L_INT nRet;
   FILEJ2KOPTIONS J2KOptions;
   // get the default values.
   nRet = LFileSettings::GetDefaultJ2KOptions(&J2KOptions, sizeof(FILEJ2KOPTIONS));
   if(nRet != SUCCESS)
      return nRet;
   // make the default values the current values.
   // The next time a JPEG2000 file is saved, it will be saved using the default options 
   nRet = LFileSettings::SetJ2KOptions(&J2KOptions);
