Thanks: 5 times

i'm trying to save this file "C:\Users\Public\Documents\LEADTOOLS Images\leadtools.pdf" with LT20 winforms .net c# that is loaded as LeadDocument but the size is increased from 89KB to 123MB without changing anything because "LeadDocument.SaveToFile" save it as rasterimage using default settings

Is there an easy way to auto save the file keeping the same input file format for all pages that haven't been changed?


input file has only vector pages but on DocumentViewer only 1st page is rasterized but the rest is unchanged.
the output should be an mixed file with 1st as raster and the rest as vector.


input file has only vector pages but on DocumentViewer we have added annotations.
the output should be an file with only vector pages and annotations saved inside the file (if file is pdf or tiff)

From your inquiries, it appears that you may want to utilize the DocumentConverter class to export the LEADDocument you are using in the Document Viewer.

The DocumentConverter will allow you to save the mixed PDF (raster & vector) to document format, which should retain the original mix of raster and vector pages.
You are currently using the SaveToFile() method which only allows you to save the file as a complete raster PDF. The DocumentConverter will also allow you to indicate how you want the drawn annotations to be saved in the AnnotationsMode property.
For your use-case you will want to use DocumentConverterAnnotationsMode.Embed, to embed the annotations into the TIFF or PDF file. We do have a tutorial on how to use the DocumentConverter class located here:

If you have any further questions regarding the process above please feel free to reach back out to us.
