kk,

There is no simple solution as it depends on your PDF file.

One option would be to call QP.RenderPageToFile with a low DPI value to a Bitmap and then use code to read the pixels line by line searching for the 1st non white pixel.  You would need to search from 4 different directions to detect the top, left, right and bottom margins.  You then convert this pixel position back to points.  If you render at 72dpi then pixels = points.

Andrew,

Thanks for the response.  I need to determine this programmatically.  How would I do that?

kk,

You could always adjust the CropBox and make it smaller.  Technically it doesn't remove any content from the PDF file but it adjusts the visiblee rectangle that is used for displaying the PDF in Acrobat and other viewers.

This would assume you know how big the borders are in the first place.  Depending on the PDF there could be ways to determine this programmatically.

  QP.LoadFromFile ....
  QP.SetPageBox(2, left, top, width, height);  // 2 = CropBox.
  QP.SaveToFile ..

Andrew.

Is it possible to remove the white spaces (along the borders) of the PDF document using the QuickPDF library?
