本文介绍如何使用Spire.Presentation for Java在PPT幻灯片中设置自定义动画路径。
import com.spire.presentation.*;
import com.spire.presentation.collections.CommonBehaviorCollection;
import com.spire.presentation.drawing.FillFormatType;
import com.spire.presentation.drawing.animation.*;
import java.awt.*;
import java.awt.geom.Point2D;
public class CustomAnimationPath {
public static void main(String[] args) throws Exception {
//创建一个空白PPT文档
Presentation ppt = new Presentation();
//获取第一张幻灯片(新建的幻灯片文档默认已包含一张幻灯片)
ISlide slide = ppt.getSlides().get(0);
//添加形状到幻灯片
IAutoShape shape = slide.getShapes().appendShape(ShapeType.FIVE_POINTED_STAR,new Rectangle(180, 100, 170, 170));
shape.getFill().setFillType(FillFormatType.GRADIENT);
shape.getFill().getGradient().getGradientStops().append(0, KnownColors.LIGHT_PINK);
shape.getFill().getGradient().getGradientStops().append(1, KnownColors.PURPLE);
shape.getShapeStyle().getLineColor().setColor(Color.white);
//添加动画效果,并设置动画效果类型为PATH_USER(自定义类型)
AnimationEffect effect = slide.getTimeline().getMainSequence().addEffect(shape, AnimationEffectType.PATH_USER);
//获取自定动画的CommonBehavior集合
CommonBehaviorCollection commonBehaviorCollection = effect.getCommonBehaviorCollection();
//设置动画动作运动起点及路径模式
AnimationMotion motion = (AnimationMotion)commonBehaviorCollection.get(0);
motion.setOrigin(AnimationMotionOrigin.LAYOUT);
motion.setPathEditMode(AnimationMotionPathEditMode.RELATIVE);
//设置动作路径
MotionPath motionPath = new MotionPath();
motionPath.addPathPoints(MotionCommandPathType.MOVE_TO,new Point2D.Float[]{new Point2D.Float(0,0)},MotionPathPointsType.CURVE_AUTO,true);
motionPath.addPathPoints(MotionCommandPathType.LINE_TO,new Point2D.Float[]{new Point2D.Float(0.1f,0.1f)},MotionPathPointsType.CURVE_AUTO,true);
motionPath.addPathPoints(MotionCommandPathType.LINE_TO,new Point2D.Float[]{new Point2D.Float(-0.1f,0.2f)},MotionPathPointsType.CURVE_AUTO,true);
motionPath.addPathPoints(MotionCommandPathType.END,new Point2D.Float[]{},MotionPathPointsType.CURVE_AUTO,true);
//设置动作路径到动画
motion.setPath(motionPath);
//保存文档
ppt.saveToFile("result.pptx", FileFormat.PPTX_2013);
ppt.dispose();
}
}
设置结果:
