Detailed Description

The PageResizer class provides functionality to resize PDF pages to a specified target page size using various resizing methods.

The PageResizer class provides functionality to resize PDF pages to a specified target page size using various resizing methods. It adjusts page dimensions, content, annotations, and resources accordingly, also supports configuration options for maintaining the aspect ratio during the resize operation.

Member Enumeration Documentation

HorizontalAnchorPoint

enum iText.Kernel.Pdf.PageResizer.HorizontalAnchorPoint

strong

Enum representing the horizontal anchor point used in the resizing and alignment of a page or content.

Enum representing the horizontal anchor point used in the resizing and alignment of a page or content.

The horizontal anchor point specifies the horizontal alignment, determining the reference point for positioning during resizing operations. Possible values include:

• LEFT

ResizeType

enum iText.Kernel.Pdf.PageResizer.ResizeType

strong

Enum representing the available types of resizing strategies when modifying the dimensions of a PDF page.

Enum representing the available types of resizing strategies when modifying the dimensions of a PDF page. These strategies determine how the content is scaled relative to the new size.

VerticalAnchorPoint

enum iText.Kernel.Pdf.PageResizer.VerticalAnchorPoint

strong

Represents the vertical alignment points used for resizing or aligning elements, particularly in the context of page rescaling.

Represents the vertical alignment points used for resizing or aligning elements, particularly in the context of page rescaling.

The available anchor points are:

• TOP: The top edge of the element serves as the reference point for alignment.
• CENTER: The center of the element is used as the alignment reference.
• BOTTOM: The bottom edge of the element serves as the reference point for alignment.

This enumeration is employed by the PageResizer class to determine the vertical alignment of content during resizing operations.

Constructor & Destructor Documentation

PageResizer()

iText.Kernel.Pdf.PageResizer.PageResizer ( PageSize  size, PageResizer.ResizeType  type  )

inline

Constructs a new PageResizer instance with the specified page size and resize type.

Parameters

Member Function Documentation

GetHorizontalAnchorPoint()

virtual PageResizer.HorizontalAnchorPoint iText.Kernel.Pdf.PageResizer.GetHorizontalAnchorPoint ( )

inlinevirtual

Retrieves the horizontal anchor point of the PageResizer.

Returns

the horizontal anchor point, which determines the horizontal alignment (e.g., LEFT, CENTER, RIGHT).

GetVerticalAnchorPoint()

virtual PageResizer.VerticalAnchorPoint iText.Kernel.Pdf.PageResizer.GetVerticalAnchorPoint ( )

inlinevirtual

Retrieves the vertical anchor point of the PageResizer.

Returns

the vertical anchor point, which determines the vertical alignment (e.g., TOP, CENTER, BOTTOM).

Resize()

virtual void iText.Kernel.Pdf.PageResizer.Resize ( PdfPage  page )

inlinevirtual

Resizes a given PDF page based on the specified dimensions and resize type.

Resizes a given PDF page based on the specified dimensions and resize type. Depending on the resize type, the aspect ratio may be maintained during scaling. Updates the page's content, annotations, and resources to reflect the new size.

Parameters

page	the PDF page to be resized

SetHorizontalAnchorPoint()

virtual void iText.Kernel.Pdf.PageResizer.SetHorizontalAnchorPoint ( PageResizer.HorizontalAnchorPoint  anchorPoint )

inlinevirtual

Sets the horizontal anchor point, which determines how the horizontal alignment is handled (e.g., LEFT, CENTER, RIGHT).

Parameters

anchorPoint

the horizontal anchor point to set; it specifies the horizontal alignment type for resizing operations

SetVerticalAnchorPoint()

virtual void iText.Kernel.Pdf.PageResizer.SetVerticalAnchorPoint ( PageResizer.VerticalAnchorPoint  anchorPoint )

inlinevirtual

Sets the vertical anchor point, which determines how the vertical alignment is handled (e.g., TOP, CENTER, BOTTOM).

Parameters

anchorPoint

the vertical anchor point to set; it specifies the vertical alignment type for resizing operations
