java - Save jzy3d Chart in PDF using DynamicReports -


i'm using dynamicreports api create pdf report displaying results of java application (tables , charts). 1 of chart have display 3d surface plot build using jzy3d 0.9.0.

here code:

            }         };          // define range , precision function plot         range range = new range(-150, 150);         int steps = 50;          // create surface drawing function         org.jzy3d.plot3d.primitives.shape surface = builder.buildorthonormal(new orthonormalgrid(range, steps, range, steps), mapper);         surface.setcolormapper(new colormapper(new colormaprainbow(), surface.getbounds().getzmin(), surface.getbounds().getzmax(), new org.jzy3d.colors.color(1, 1, 1, .5f)));         surface.setfacedisplayed(true);         surface.setwireframedisplayed(false);         surface.setwireframecolor(org.jzy3d.colors.color.black);          // create chart , add surface         org.jzy3d.chart.chart chart = new org.jzy3d.chart.chart(quality.advanced);         chart.getscene().getgraph().add(surface);          return chart;     }  }

this code works if call method chartlauncher.openchart(chart) (consequently opening frame chart displayed in) createheatmap() before returning chart, otherwise createheatmap().screenshot() returns null. if need create , export pdf of chart without displaying chart in java application?

note: if possible, i'd prefer use jzy3d 0.9.0 , not jzy3d 0.9.1 because otherwise should modify lot of code written , tested.

able capture screenshot in way:

chart c = awtchartcomponentfactory.chart(quality.nicest,org.jzy3d.chart.factories.ichartcomponentfactory.toolkit.offscreen); c.screenshot(); bufferedimage = ((offscreencanvas)c.getcanvas()).getrenderer()).getlastscreenshotimage();

java - Warning equals/hashCode on @Data annotation lombok with inheritance -

i have entity inherits other. on other hand, i'm using lombok project reduce boilerplate code, put @data annotation. annotation @data inheritance produces next warning: generating equals/hashcode implementation without call superclass, though class not extend java.lang.object. if intentional, add '@equalsandhashcode(callsuper=false)' type. is advisable add annotation @equalsandhashcode (callsuper = true) or @equalsandhashcode (callsuper = false) ? if not added, 1 callsuper=false or callsuper=true ? the default value false . 1 if don't specify , ignore warning. yes, recommended add @equalsandhashcode annotation on @data annotated classes extend else object. cannot tell if need true or false , depends on class hierarchy, , need examined on case-by-case basis. however, project or package, can configure in lombok.config call super methods if not direct subclass of object. lombok.equalsandhashcode.callsuper = call for configuration system ...
