| 3 * src/main/java/de/intevation/gnv/state/profile/verticalcrosssection/VerticalCrossSectionOutputState.java: | |
| 4 Generate iso lines by dividing palette ranges in two | |
| 5 parts each and traces them. This shows that the ideas described | |
| 6 by K. Jancke in gnv-issues/issue108 are possible not the | |
| 7 right way to go. Applying this strategy there would be | |
| 8 locally to many isolines if there is a steep gradient. | |
| 9 On the other side large areas are splitted in too less sections | |
| 10 by too less iso lines. A better way may be a splitting with | |
| 11 a look at the areas and shapes of regions. Large, round areas need | |
| 12 more splits. Long, thin areas need less splits. | |
| 13 | |
| 14 * src/main/java/de/intevation/gnv/raster/IsoPolygonSeriesProducer.java: | |
| 15 Stabilized iso line hashing a bit. Added line width to | |
| 16 give iso lines a more appealing presentation in the chart. | |
| 17 The according value is stored in "line.width". | |
| 18 | |
| 19 * src/main/java/de/intevation/gnv/raster/Vectorizer.java: Fixed silly | |
| 20 bug when simplifying lines. This prevented iso line | |
| 21 | |
| 22 * src/main/java/de/intevation/gnv/raster/Palette.java: Fixed index issue | |
| 23 when generating a divided palette. | |
| 24 | |
| 25 * src/main/java/de/intevation/gnv/jfreechart/PolygonSeries.java: | |
| 26 Do not crash with NPE any more when not having any series. | |
| 27 | |
| 28 * src/main/java/de/intevation/gnv/jfreechart/PolygonDataset.java: | |
| 29 Added method to add a whole collection of series. Useful to add | |
| 30 iso lines to dataset. | |
| 31 | |
| 32 * src/main/java/de/intevation/gnv/jfreechart/PolygonRenderer.java: | |
| 33 Set the "line.width" attribute when rendering lines. | |
