Class PixOutliner
java.lang.Object
uk.ac.starlink.ttools.plot2.layer.PixOutliner
- All Implemented Interfaces:
Outliner
- Direct Known Subclasses:
PolygonOutliner
,SizeForm.SizeOutliner
,SizeXyForm.SizeXyOutliner
Partial Outliner implementation which calculates its bin plan
simply by using the
create2DPainter
method.
If no clever shortcut presents itself, this is a reasonable way to do it.- Since:

calculateBinPlan
public Object calculateBinPlan(Surface surface, DataGeom geom, Map<AuxScale, Span> auxRanges, DataStore dataStore, DataSpec dataSpec, Object[] knownPlans) Description copied from interface:Outliner
Calculates an opaque object which contains the drawing of this outliner represented as an array of bins, one per pixel. To make sense of the returned object, use theOutliner.getBinCounts(java.lang.Object)
andOutliner.getPointCount(java.lang.Object)
methods.If one of the supplied knowPlans fits the bill, it will be returned without further calculation.
- Specified by:
calculateBinPlan
in interfaceOutliner
- Parameters:
surface
- plot surfacegeom
- coordinate geometryauxRanges
- map of scale information required for plotdataStore
- data storagedataSpec
- coordinate specificationknownPlans
- list of existing plans- Returns:
- bin plan, either newly calculated or taken from
knownPlans
-
getBinCounts
Description copied from interface:Outliner
Returns the bin contents for a given bin plan produced by this object.- Specified by:
getBinCounts
in interfaceOutliner
- Parameters:
binPlan
- bin plan returned fromcalculateBinPlan
- Returns:
- array of counts, one element per bin
-
getPointCount
Description copied from interface:Outliner
Returns the number of data positions which contributed to a BinPlan generated by this object. This may or may not be the same as the sum of the pixel counts in the binCounts array; if each data position might contribute multiple pixel hits, the numbers will not be the same.- Specified by:
getPointCount
in interfaceOutliner
- Parameters:
binPlan
- bin plan returned fromcalculateBinPlan
- Returns:
- number of data positions in plan
-
getReport
Description copied from interface:Outliner
Obtains information associated with the plot.
