Static Public Attributes | |
static final int | e_TypeBezierTo = 4 |
Indicates that this point is a control point or ending point for a Bezier spline. | |
static final int | e_TypeBezierToCloseFigure = 5 |
Indicates that this point is the ending point for a Bezier spline, and this point will also be connected to the nearest com.foxit.sdk.common.Path.e_TypeMoveTo point before this point, in order to close current figure. | |
static final int | e_TypeLineTo = 2 |
Indicates that a line is drawn from the previous point to this point. | |
static final int | e_TypeLineToCloseFigure = 3 |
Indicates that a line is drawn from the previous point to this point, and this point will also be connected to the nearest com.foxit.sdk.common.Path.e_TypeMoveTo point before this point, in order to close current figure. | |
static final int | e_TypeMoveTo = 1 |
Indicates that the point is the first point of a figure. | |
This class represents a path which contains one or more figures.
com.foxit.sdk.common.Path.Path | ( | Path | other | ) |
Constructor, with another path object.
[in] | other | Another path object. |
boolean com.foxit.sdk.common.Path.appendEllipse | ( | RectF | rect | ) | throws com.foxit.sdk.PDFException |
Add an ellipse figure to the end of current path.
[in] | rect | The enclosing rectangle of an ellipse figure. |
boolean com.foxit.sdk.common.Path.appendRect | ( | RectF | rect | ) | throws com.foxit.sdk.PDFException |
Add a rectangle figure to the end of current path.
[in] | rect | A rectangle which specifies a rectangle figure. |
void com.foxit.sdk.common.Path.clear | ( | ) | throws com.foxit.sdk.PDFException |
Clear all points.
boolean com.foxit.sdk.common.Path.closeFigure | ( | ) | throws com.foxit.sdk.PDFException |
Close current figure (which is also the last figure in current path).
When closing current figure, the last point's type may be changed:
boolean com.foxit.sdk.common.Path.cubicBezierTo | ( | PointF | point1, |
PointF | point2, | ||
PointF | point3 | ||
) | throws com.foxit.sdk.PDFException |
Add a cubic bezier spline to the end of current figure, by three points: two control points and one target point.
If this function succeeds, parameter point3 will become the new "current point".
[in] | point1 | New point as the first control point for cubic bezier, in [PDF coordinate system] (com.foxit.sdk.pdf.PDFPage). |
[in] | point2 | New point as the second control point for cubic bezier, in [PDF coordinate system] (com.foxit.sdk.pdf.PDFPage). |
[in] | point3 | New point as target point for cubic bezier, in PDF coordinate system. |
PointF com.foxit.sdk.common.Path.getPoint | ( | int | index | ) | throws com.foxit.sdk.PDFException |
Get a point specified by index.
[in] | index | The index of the point. Valid range: 0 to (count-1). count is returned by function Path.getPointCount . |
int com.foxit.sdk.common.Path.getPointCount | ( | ) | throws com.foxit.sdk.PDFException |
Get the count of points.
int com.foxit.sdk.common.Path.getPointType | ( | int | index | ) | throws com.foxit.sdk.PDFException |
Get the type of a point specified by index.
[in] | index | The index of the point. Valid range: 0 to (count-1). count is returned by function Path.getPointCount . |
void com.foxit.sdk.common.Path.increasePointCount | ( | int | count | ) | throws com.foxit.sdk.PDFException |
Increase the point count and prepare adequate memory for these new points.
This function will allocate more memory for given point count and initialize these new points with point (0, 0) and type com.foxit.sdk.common.Path.e_TypeMoveTo by default. After calling this function successfully, user can use function Path.setPoint to set these new points.
[in] | count | The new point count. It should not be negative. |
boolean com.foxit.sdk.common.Path.isEmpty | ( | ) |
Check whether current object is empty or not.
When the current object is empty, that means current object is useless.
boolean com.foxit.sdk.common.Path.lineTo | ( | PointF | point | ) | throws com.foxit.sdk.PDFException |
Add a point to the end of current figure, and a line is to be drawn from current point to the new point.
If this function succeeds, the new point will become the new "current point".
[in] | point | New point, in PDF coordinate system. |
boolean com.foxit.sdk.common.Path.moveTo | ( | PointF | point | ) | throws com.foxit.sdk.PDFException |
Add a point to the end of current path, to start a new figure.
If this function succeeds, the new point will become the new "current point", and the new figure will become the new "current figure".
[in] | point | New point, in PDF coordinate system. |
boolean com.foxit.sdk.common.Path.removePoint | ( | int | index | ) | throws com.foxit.sdk.PDFException |
Remove a point specified by index.
[in] | index | The index of the point to be removed. Valid range: 0 to (count-1). count is returned by function Path.getPointCount . |
boolean com.foxit.sdk.common.Path.setPoint | ( | int | index, |
PointF | point, | ||
int | type | ||
) | throws com.foxit.sdk.PDFException |
Change the value and type of a point specified by index.
[in] | index | The index of the point. Valid range: 0 to (count-1). count is returned by function Path.getPointCount . |
[in] | point | The new point to set, in PDF coordinate system. |
[in] | type | The type used to set to the new point. Please refer to values starting from com.foxit.sdk.common.Path.e_TypeMoveTo and this should be one of these values. |
void com.foxit.sdk.common.Path.transform | ( | Matrix2D | matrix | ) | throws com.foxit.sdk.PDFException |
Transform all points in current path with a given matrix.
[in] | matrix | A matrix used for transforming. |
