ExportPages vs ExportPdf Resulting file size differences

SDK Version 9 Search and Retrieval
Updated March 13, 2015
asked on March 11, 2015

When exporting a tif image to pdf using:

DE.ExportPdf(DI, DI.AllPages, PdfExportOptions.None, path);

the resulting file size is typically around 300% larger than when just exporting the tif:

DE.ExportPages(DI, DI.AllPages, path);

Is it normal to see this kind of size increase when exporting to pdf? 

fyi: I'm using the sdk in a web service that allows our clients to download images.  It is important for the service to minimizes download times.

Since the introduction of LF8, I have noticed that the export to PDF has resulted in a bloated PDF.  I am not sure what is happening or why, but yes, unfortunately the built in PDF conversion will create a much larger file.

We switched to a different library to create PDFs in Laserfiche 8. We'll see if there's something that can be done to reduce the size.

Hello,

in laserfiche client go to tools>options menu

Export image:

  • Select Include all other annotations on exported images to retain annotations on pages when they are exported. (This setting does not have any effect on redactions.) If you do not want to include annotations, clear this option.
  • Select Convert annotations into PDF annotations if you want to convert Laserfiche annotations on pages into PDF annotations when you export a document as a PDF. If you want to export the PDF without annotations, clear this option.

 

Check and modify these options to maintain the PDF document size after export:

  • Select When generating PDFs from pages, create as PDF/A to generate PDFs in PDF/A format rather than standard PDF format. PDF/A files are intended for long-term archiving of documents, but may be larger than standard PDF documents. The PDF/A file type does not support some annotation types, which will not be included in the exported file. To export PDFs in standard PDF format, clear this option.
  • In the Quality level option, specify the quality of the exported document as a percentage. Higher quality will result in a larger file size.
