33a9cb5b2d bugfix: straight lines in pie and chord were not drawn as curve in DrawMode=DrawAsMathematicalCurve 2020-09-03 23:28:48 +02:00

279ef7880a - improved: geometric objects now use an adaptive drawing algorithm to represent curves (before e.g. ellipses were always separated into a fixed number of line-segments)
- improved: constructors and access functions for several geometric objects (e.g. more constructors, additional functions to retrieve parameters in diferent forms, iterators for polygons, ...)
- new: all geometric objects can either be drawn as graphic element (i.e. lines are straight line, even on non-linear axes), or as mathematical curve (i.e. on non-linear axes, lines become the appropriate curve representing the linear function, connecting the given start/end-points). The only exceptions are ellipses (and the derived arcs,pies,chords), which are always drawn as mathematical curves

7e9bad29b4 fix for issue #45:
- for Qt 5.15: added missing #include statements that became necessary since Qt 5.15
- for Qt 5.15: fixed use of several deprecated functions
- for Qt 5.15/6: removed usage of QMatrix

686fb1eeb1 using mix-in class JKQTPColorPaletteWithModifierStyleAndToolsMixin now also in JKQTPMathImage ... 2019-07-31 22:10:26 +02:00

4347d27c04 * reworked color-palette-system:
1. added several new (JKQTPMathImageBone, JKQTPMathImageCool, JKQTPMathImageCopper, JKQTPMathImageAutumn, JKQTPMathImageSeismic, JKQTPMathImageTerrain, JKQTPMathImageViridis, JKQTPMathImageMagma, JKQTPMathImageInferno, JKQTPMathImagePlasma)
  2. reworked LUT-types (now a QVector, instead of a C-array, suing malloc)
  3. reworked available functions to build LUTs (cleanup, more options, clearer names)
  4. added functions to load palettes from files
  5. Improved documentation
* added example for user-controlled color palettes

77d799a742 - removed many compiler warnings
- enabled compiler-warnings in CMake-build
- several bugfixes (also to appveyor.yml)
- removed some function from JKQTBasePlotter, which were (messy) shortcuts to adding graphs
