Get document information Leave feedback
GroupDocs.Signature allows to get document information which includes:
- getFileType
- getSize
- getPageCount
- Pages dimensions - getHeight and getWidth for each page in a document Pages collection.
The following code snippet demonstrates how to obtain information about document stored on local disk.
Signature signature = new Signature("sample.pdf");
// Document description
IDocumentInfo docInfo = signature.getDocumentInfo();
System.out.print("Document contains " + docInfo.getPageCount() + " pages");
System.out.print("File type is " + docInfo.getFileType().getFileFormat());
System.out.print("Width for Max Height " + docInfo.getWidthForMaxHeight());
System.out.print("Max Page Height" + docInfo.getMaxPageHeight());
System.out.print("File size in bytes is " + docInfo.getSize());
System.out.print("Width of first page is " + docInfo.getPages().get(0).getWidth());
for(PageInfo page : docInfo.getPages()){
System.out.print("- page-"+ page.getPageNumber()+ " Height " + page.getHeight() + " Width " + page.getWidth());
}
The following code snippet demonstrates how to obtain information about document provided as a stream.
FileInputStream stream = new FileInputStream("sample.pdf")
Signature signature = new Signature(stream );
// Document description
IDocumentInfo docInfo = signature.getDocumentInfo();
System.out.print("Document contains " + docInfo.getPageCount() + " pages");
System.out.print("File type is " + docInfo.getFileType().getFileFormat());
System.out.print("Width for Max Height " + docInfo.getWidthForMaxHeight());
System.out.print("Max Page Height" + docInfo.getMaxPageHeight());
System.out.print("File size in bytes is " + docInfo.getSize());
System.out.print("Width of first page is " + docInfo.getPages().get(0).getWidth());
for(PageInfo page : docInfo.getPages()){
System.out.print("- page-"+ page.getPageNumber()+ " Height " + page.getHeight() + " Width " + page.getWidth());
}
