Noli Turbare - Govert's Tools

PDF Tools

PDF has become the standard for distribution of graphical information.

 

Most of the PDF tools that I have made are based on iTextSharp, the .NET version of iText, made by Bruno Lowagie and Paulo Soares.

PDF Cropper

Automatically remove white space around PDF's

PDF Cropper

 

Some large size PDF documents like CAD drawings or posters have excessive white space around the actual image, or around the intended drawing border. This occurs when the PDF's were created on a page size that was larger than the actual document. Printing of these PDF files is often problematic; when the output must be enlarged, the white space is enlarged as well. Besides it is often difficult to position the image on paper, or it simply costs more paper and means extra work afterwards for manual trimming and folding. This tool is based on iTextSharp and uses GhostScript to find the extents of the imaged area.

 

PDF Cropper offers these features:

  • Automatically crop multiple single- and multipage PDF's
  • Optionally crop all pages of multipage documents to the minimum common imaged size
  • Optionally keep some white space around the image
  • Optionally crop to a standard page size (currently DIN-sizes)
  • Note that it does not crop the white space from raster images
  • Crop on the trimbox (if defined in the PDF)
  • Drag and drop

Update June 21st, 2010: problem of "invisible" program solved. The program became invisible (positioned far outside the screen) when it was ended abnormally while it was minimized, and then started again.

 

GhostScript and .NET 2.0 must be available (if this is not the case, install these first). Then unzip the .EXE file from the downloaded ZIP-archive; place it in a folder and create a shortcut to the executable. Click "Configure" to tell where the GhostScript binaries are (typically C:\Program Files\GS\GS8.7x\bin). Download
