Get Page Information

PDF Xpress™ recovers PDF per-page characteristics that describe how that page should be presented on display or printer devices.

Applications that report page size should recover PageInfo instances with either the GetInfo(Int32) method or the GetInfo(Int32,PdfCoordinateSystem) method using RotatedCroppedUserSpace.
Applications that handle coordinate system conversions should recover PageInfo instances with the GetInfo(Int32,PdfCoordinateSystem) method using DefaultUserSpace.

Refer to topic PDF Coordinate Systems for additional information.

Get Physical Page Dimensions

The following example shows how to recover the physical dimensions of a PDF page, expressed in inches:

C# Example	Copy Code
public String GetPageSizeInInches( Document doc, Int32 pageIndex ) { PageInfo pageInfo = doc.GetInfo(pageIndex); return String.Format( "Page {0} dimensions are {1}\"x{2}\"", new object[] { pageIndex, pageInfo.ClipWidth / 72.0, PageInfo.ClipHeight / 72.0 }); }

C# Example

Copy Code

public String GetPageSizeInInches( Document doc, Int32 pageIndex )
{
    PageInfo pageInfo = doc.GetInfo(pageIndex);
    return String.Format( "Page {0} dimensions are {1}\"x{2}\"",
        new object[] { pageIndex, pageInfo.ClipWidth / 72.0,
                PageInfo.ClipHeight / 72.0 });
}

Get Page CropBox

The following example shows how to recover the PDF page CropBox, expressed in default user space units:

C# Example	Copy Code
public String GetCropBox( Document doc, Int32 pageIndex ) { PageInfo pageInfo = doc.GetInfo(pageIndex, PdfCoordinateSystem.RotatedCroppedUserSpace); return String.Format( "Page {0} CropBox is [ left={1:f4} bottom={2:f4} right={3:f4} top={4:f4} ]", new object[] { pageIndex, pageInfo.ClipX, pageInfo.ClipY, pageInfo.ClipX + pageInfo.ClipWidth, pageInfo.ClipY + pageInfo.ClipHeight }); }

C# Example

Copy Code

public String GetCropBox( Document doc, Int32 pageIndex )
{
    PageInfo pageInfo = doc.GetInfo(pageIndex,
        PdfCoordinateSystem.RotatedCroppedUserSpace);
   
    return String.Format(
        "Page {0} CropBox is [ left={1:f4} bottom={2:f4} right={3:f4} top={4:f4} ]",
        new object[] { pageIndex,
            pageInfo.ClipX, pageInfo.ClipY,
            pageInfo.ClipX + pageInfo.ClipWidth,
            pageInfo.ClipY + pageInfo.ClipHeight });
}

Get Page MediaBox

The following example shows how to recover the PDF page MediaBox, expressed in default user space units:

C# Example	Copy Code
public String GetMediaBox( Document doc, Int32 pageIndex ) { PageInfo pageInfo = doc.GetInfo(pageIndex, PdfCoordinateSystem.RotatedCroppedUserSpace); return String.Format( "Page {0} CropBox is [ left={1:f4} bottom={2:f4} right={3:f4} top={4:f4} ]", new object[] { pageIndex, pageInfo.MediaX, pageInfo.MediaY, pageInfo.MediaX + pageInfo.MediaWidth, pageInfo.MediaY + pageInfo.MediaHeight }); }

C# Example

Copy Code

public String GetMediaBox( Document doc, Int32 pageIndex )
{
    PageInfo pageInfo = doc.GetInfo(pageIndex,
        PdfCoordinateSystem.RotatedCroppedUserSpace);
   
    return String.Format(
        "Page {0} CropBox is [ left={1:f4} bottom={2:f4} right={3:f4} top={4:f4} ]",
        new object[] { pageIndex,
            pageInfo.MediaX, pageInfo.MediaY,
            pageInfo.MediaX + pageInfo.MediaWidth,
            pageInfo.MediaY + pageInfo.MediaHeight });
}
