http://www.amyuni.com/en/developer/pdfcreator/features.html” rel=“nofollow noreferer”>Amyuni PDF Publishing .Net。 您可使用以下方法:rel=“nofollow noreferer” IacDocument.GetObjectsIn Rectangle,用于检索你感兴趣的所有“图表物体”:
IacDocument.GetObjectsIn Rectangle 方法
The GetObjectsInRectangle method gets all the objects that are in the
specified rectangle.
之后,你可以翻开页上的所有物体,删除你不感兴趣的物体:
//open a pdf document
document.Open (testfile,"");
IacPage page1 = document.GetPage (1);
Amyuni.PDFCreator.IacAttribute attribute = page1.AttributeByName ("Objects");
// listobj is an array list of graphic objects
System.Collections.ArrayList listobj = (System.Collections.ArrayList) attribute.Value;
foreach ( object pdfObj in listobj )
{
// if pdfObj is not in the collection of interest
// then call pdfObj.Delete();
}
Update:
Amyuni PDF Creator .Net version 5.0 adds a new method IacDocument.Redact which might also be helpful in this kind of scenario:
The Redact method retrieves all the objects of the specified type in
the specified rectangle, deletes them, and draws a solid color
rectangle at their place.
