Custom function to optimize PDF in FileMaker via DynaPDF


This little function can be called anywhere to optimize a PDF. Of course you should initialize DynaPDF in startup script of your solution. But than you can call OptimizePDF function everywhere and pass in a PDF container value. The PDF is optimized and returned.

If you like add further parameters to decide what optimization to do. The example be low uses a good default setting to reduce PDFs for email delivery.

 

# Custom Function OptimizePDF(InputPDF)

#

# Optimizes PDF and returns either new one or old one in case of error.

 

Let ([ 

PDF = MBS("DynaPDF.New");

OpenResult = MBS("DynaPDF.OpenPDFFromContainer"; PDF; InputPDF);

OpenError = MBS("IsError");

ImportResult = MBS("DynaPDF.ImportPDFFile"; PDF);

ImportError = MBS("IsError");

Options = "FlattenLayers DeleteInvPaths ScaleImages NewLinkNames DeletePrivateData IgnoreZeroLineWidth DeleteAlternateImages DeleteThumbnails";

OptimizeResult = MBS("DynaPDF.Optimize"; PDF; Options; 50; 50; 50; 150; 150; 150; "JPEG"; "JPEG"; "JPEG");

OptimizeError = MBS("IsError");

OutputPDF = MBS("DynaPDF.Save"; PDF; GetAsText(InputPDF));

SaveError = MBS("IsError");

ReleaseError = MBS("DynaPDF.Release"; PDF);

 

Result = If( 

  // all okay?

  OpenError = 0 and ImportError = 0 and OptimizeError = 0 and SaveError = 0 and MBS( "Container.GetSize"; OutputPDF; "PDF " ) > 0

  // than return new PDF

  OutputPDF;

  // return old PDF

  InputPDF)

 

];

 

result )
