Page 353 of 821

Return values:

If the function succeeds the return value is 1 and the parameter Annot is filled with values. If the

function fails the return value is 0 and the parameter Annot is left unchanged.

GetAnnotBBox

Syntax:

SI32 pdfGetAnnotBBox(

const PPDF* IPDF)

// Instance pointer

UI32 Handle,

// Annotation handle

struct TPDFRect ADDR BBox) // see below

struct TPDFRect

{

double Left;

// Lower x-coordinate

double Bottom; // Lower y-coordinate

double Right;

// Upper x-coordinate

double Top;

// Upper y-coordinate

};

This function retrieves the bounding box of an annotation measured in bottom-up coordinates. A

bounding box is defined as rectangle giving the coordinates of a pair of diagonally opposite corners.

Remarks:

It is possible to change the bounding box of an annotation with the function ChangeAnnotPos().

Return values:

If the function succeeds the return value is 1 and the parameter BBox is filled with values. If the

function fails the return value is 0 and the parameter BBox is left unchanged.

GetAnnotCount

Syntax:

SI32 pdfGetAnnotCount(

const PPDF* IPDF) // Instance pointer

The function returns the number of annotations currently used in the document. Note: This value

includes also annotations which were deleted by DeleteAnnotation() because annotations are not

physically deleted at runtime. This value can be used to loop over all annotations. Annotation

handles are simple array indexes.
