Class Markup

The meaning of an annotation's Contents entry varies by annotation type. Typically, it is the text that shall be displayed for the annotation or, if the annotation does not display text, an alternate description of the annotation's contents in human-readable form. In either case, the Contents entry is useful when extracting the document's contents in support of accessibility to users with disabilities or for other purposes. Many annotation types are defined as markup annotations because they are used primarily to mark up PDF documents. These annotations have text that appears as part of the annotation and may be displayed in other ways by a conforming reader, such as in a Comments pane. Markup annotations may be divided into the following groups:

Free text annotations display text directly on the page. The annotation's Contents entry specifies the displayed text.
Most other markup annotations have an associated pop-up window that may contain text. The annotation's Contents entry specifies the text that shall be displayed when the pop-up window is opened. These include text, line, square, circle, polygon, polyline, highlight,underline, squiggly-underline, strikeout, rubber stamp, caret, ink, and file attachment annotations.
Sound annotations do not have a pop-up window but may also have associated text specified by the Contents entry. When separating text into paragraphs, a CARRIAGE RETURN (0Dh) shall be used and not, for example, a LINE FEED character (0Ah). A subset of markup annotations is called text markup annotations.

The remaining annotation types are not considered markup annotations:

The pop-up annotation type shall not appear by itself; it shall be associated with a markup annotation that uses it to display text. If an annotation has no parent, the Contents entry shall represent the text of the annotation, otherwise it shall be ignored by a conforming reader.
For all other annotation types (Link, Movie, Widget, PrinterMark, and TrapNet), the Contents entry shall provide an alternate representation of the annotation's contents in human-readable form, which is useful when extracting the document's contents in support of accessibility to users with disabilities or for other purposes.

Markup(Annot)

Creates a Markup annotation and initialize it using given annotation object.

Declaration

public Markup(Annot ann)

Parameters

Type	Name	Description
Annot	ann	the annot

Remarks

The constructor does not copy any data, but is instead the logical equivalent of a type cast.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

Markup(Obj)

Creates a Markup annotation and initialize it using given SDF::Obj object.

Declaration

public Markup(Obj d)

Parameters

Type	Name	Description
Obj	d	existing Markup object

Remarks

The constructor does not copy any data, but is instead the logical equivalent of a type cast.

Methods

Dispose(bool)

Declaration

[HandleProcessCorruptedStateExceptions]
protected override void Dispose(bool A_0)

Parameters

Type	Name	Description
bool	A_0

Overrides

Annot.Dispose(bool)

GetBorderEffect()

Gets the Border Effect of the Markup Annotation.

Declaration

public Markup.BorderEffect GetBorderEffect()

Type	Description
Markup.BorderEffect	An entry from the enum "BorderEffect" that represents the border effect.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

GetBorderEffectIntensity()

Gets the Border Effect Intensity of the Markup Annotation.

Declaration

public double GetBorderEffectIntensity()

Returns

Type	Description
double	A number representing the border effect.

Remarks

The BorderEffectIntensity value is a number describing the intensity of the effect, in the range 0 to 2. Default value: 0.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

GetContentRect()

Gets the inner bounding rectangle of the Square. (Optional; PDF 1.5)

Declaration

public Rect GetContentRect()

Returns

Type	Description
Rect	A difference between the inner bounding rectangle and a positon rectangle may occur in situations where a border effect (described by BE) causes the size of the Rect to increase beyond that of the square or Square

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

GetCreationDates()

Gets the creation date of the Markup Annotation

Declaration

public Date GetCreationDates()

Returns

Type	Description
Date	A Date object indicating the date the Markup Annotation is created

Remarks

The Date object not only includes date, it actually includes both date and time when the annotation was created. This corresponds to the 'CreationDate' field of the markup annotation's dictionary.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

GetInteriorColor()

Gets the interior color of the Square. (Optional; PDF'1.4 )

Declaration

public ColorPt GetInteriorColor()

Returns

Type	Description
ColorPt	interior color

Remarks

it is necessary to make sure the consistancy between the ColorPt type and the ColorSpace::Type value. e_device_gray corresponds to an array of two numbers; e_device_rgb corresponds to an array of 3 numbers, e_device_cmyk corresponds to an array of 4 numnbers, while e_null correspons to an arry of 0 number. Entries out of the specified color space array length will be desgarded. However, missing entries for a specified color space will throw exception either when setting the color or when later retrieving color(colorspace) information.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

GetInteriorColorCompNum()

Gets the number indicating interior color space of the Square.

Declaration

public int GetInteriorColorCompNum()

Returns

Type	Description
int	An integer indicating a color space value from the ColorSpace::Type enum. That is, 1 corresponding to "e_device_gray", 3 corresponding to "e_device_rgb", and 4 corresponding to "e_device_cmyk" if color space is applicable, orelse 0 corresponding to "e_null" if the color is transparent.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

GetOpacity()

Gets the contant opacity value corresponding to the annotation.

Declaration

public double GetOpacity()

Returns

Type	Description
double	A number indicating the opacity value corresponding to the annotation.

Remarks

The constant opacity value shall be used in painting the annotation. This value shall apply to all visible elements of the annotation in its closed state (including its background and border) but not to the pop-up window that appears when the annotation is opened. The specified value shall not used if the annotation has an appearance stream in that case, the appearance stream shall specify any transparency. (However, if the compliant viewer regenerates the annotation's appearance stream, it may incorporate the CA value into the stream's content.) The implicit blend mode is Normal. Default value: 1.0. If no explicit appearance stream is defined for the annotation, it may bepainted by implementation-dependent means that do not necessarily conform to the PDF imaging model; in this case, the effect of this entry is implementation-dependent as well.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

GetPadding()

Gets the rectangle difference of the Square. (Optional; PDF 1.5)

Declaration

public Rect GetPadding()

Returns

Type	Description
Rect	A set of four numbers(represented as a Rect object) specifying the difference on the four different directions.

Remarks

rectangle difference is A set of four numbers that shall describe the numerical differences between two rectangles: the Rect entry of the annotation and the actual boundaries of the underlying square or Square. Such a difference may occur in situations where a border effect (described by BE) causes the size of the Rect to increase beyond that of the square or Square. The four numbers shall correspond to the differences in default user space between the left, top, right, and bottom coordinates of Rect and those of the square or Square, respectively. Each value shall be greater than or equal to 0. The sum of the top and bottom differences shall be less than the height of Rect, and the sum of the left and right differences shall be less than the width of Rect.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

GetPopup()

Gets the Popup object associated with this Markup annotation.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception

GetSubject()

Gets subject of the Markup Annotation.

Declaration

public string GetSubject()
