| 4 Generate iso line classes according gnv-issues/issue108: | |
| 5 | |
| 6 - If there are more than nine colors used in the chart | |
| 7 only the borders of the regions are traced. | |
| 8 - If there are less than ten colors each color region | |
| 9 is devided into two sub regions. | |
| 10 - If there are less than five colors each color region | |
| 11 is devided into five sub regions. | |
| 12 | |
| 13 Generate attribute per iso line class with the parameter value | |
| 14 of the iso line. | |
| 15 | |
| 16 * src/main/java/de/intevation/gnv/raster/IsoPolygonSeriesProducer.java: | |
| 17 Renamed inner interface from LabelGenerator to AttributeGenerator to | |
| 18 reflect the fact that the concrete label generation is a matter | |
| 19 of i18n too. The concrete label generation should be done when | |
| 20 the final chart is going to be created. TODO: Add | |
| 21 a JFreeChart style label generator to PolygonRenderer | |
| 22 | |
| 23 * src/main/java/de/intevation/gnv/raster/IsoAttributeGenerator.java: | |
| 24 New. Implements the AttributeGenerator interface. It takes | |
| 25 the indices of the neighboring regions, uses these values | |
| 26 to look into the iso palette and averages the parameter values | |
| 27 at the touching borders. This should help in cases where | |
| 28 two regions are neighbored in the chart which are not neighbored | |
| 29 in the palette which may happen by quantification artifacts. | |
| 30 | |
| 31 * src/main/java/de/intevation/gnv/raster/Palette.java: Added | |
| 32 getters to 'from' and 'to' fields. | |
| 33 | |
| 34 * src/main/java/de/intevation/gnv/math/XYColumn.java: Fixed | |
| 35 another silly bug with adding values at surface and ground. | |
| 36 | |
| 37 * ChangeLog: Typo fixes | |
