const PPDF* IPDF) // Instance pointer
The function deletes a maybe existing XFA form (XML based form) if any. This can be useful if the
PDF file contains a hybrid form because DynaPDF does not allow editing form fields as long as an
XFA form is present.
const PPDF* IPDF,
// Instance pointer
// X-Coordinate of the midpoint of the arc
// Y-Coordinate of the midpoint of the arc
double StartAngle, // Start angle
// End angle
This function draws an arc by using a start and end angle. A full circle is drawn if the start and end
angles coincide. The path is not closed, stroked or filled so that it will be invisible as long it is not
stroked, filled or both (see ClosePath() or StokePath() for further information).
The current point is connected with the start point and then updated to the end point of the arc (see
The draw direction can be changed with the function SetDrawDirection(). The start and end angles
are always measured counter clockwise independent of the drawing direction.
If the function succeeds the return value is 1. If the function fails the return value is 0.
