For any User Exit work, you must have ScanTools software and you must use a C/C++ compiler that can create Windows Dynamic Link Libraries (DLLs). Scantron has developed and tested user exits using the following development platforms:
Any User Exits that use Group 3 Compression must be modified when working with ScanTools Plus.
Change to Group 4 Compression
We recommend that you change from G3 to G4 compression by modifying any calls that read:
SetClipCompressionMethod( SLK_COMP_GROUP3 );
to:
SetClipCompressionMethod( SLK_COMP_GROUP4 );
Use Group 3 Compression
If you must use G3 Compression, the following lines in ClipHelper.cpp file’s WriteTiffFileFromClip function must be changed.
From:
case cpmGroup3:
ClipDesc.wCompression = COMPRESSION_CCITTFAX3;
if (GetCfig()->features.comint == OP10XX || ((iRowCount * iColCount) < 320000)) )
{
ClipDesc.dwCompressionOptions = 0;
}
else
{
ClipDesc.dwCompressionOptions = GROUP3OPT_2DENCODING;
}
break;
To:
case cpmGroup3:
ClipDesc.wCompression = COMPRESSION_CCITTFAX3;
ClipDesc.dwCompressionOptions = GROUP3OPT_2DENCODING;
break;
NOTE: If you use Group 3, compression option 2D encoding is required.
