The PDF file must be opened with OpenImportFile() or OpenImportBuffer() before this function can

be called.

Return values:

If the function succeeds it returns 0 or 1 depending on whether the file contains an XFA form. If the

function fails the return value is a negative error code.

GetInkList

Syntax:

LBOOL pdfGetInkList(

const ILST* List, // List pointer returned by GetAnnotEx()

float** Points,

// Address of a float* variable

UI32* Count)

// Address of a UI32 variable

The function returns a path or ink list of an Ink annotation. The array contains x/y coordinate pairs

(measured in bottom up coordinate system). The array length should be even but odd values can

occur if the annotation was imported from a malformed document.

The points of an ink list are usually drawn with bezier curves to achieve a smooth transition

between points.

Example (C++):

float* points = NULL;

TPDFAnnotationEx annot;

UI32 i, j, numAnnots, count = 0;

pdfEditPage(pdf, 1);

numAnnots = pdfGetPageAnnotCount(pdf);

for (i = 0; i < numAnnots; i++)

{

if (pdfGetPageAnnotEx(pdf, i, annot))

{

if (annot.Type == atInk)

{

for (j = 0; j < annot.InkListCount; j++)

{

if (pdfGetInkList(annot.InkList[j], &points, &count))

{

// Do something with the path

}

pdfEndPage(pdf);

Return values:

If the function succeeds the return value is 1. If the function fails the return value is 0.
