This program is a further development of QLumedit.
Current version is Eulumdat3D 2.1.4
2017-07-04 correction in drawing frames around pictures in batch mode
2017-07-04 switch between round cone values math correct or round up to next full digit (0.4 to 1.0)
2016-12-17 correction in batch export of polar diagram, scale factor ot set correctly
2016-12-12 the possibility to show C45-C225 and C135-C315 in polar and linear diagram is back
2016-10-08 a new feature is integrated and the name is changed. you can compare now two ldt files on one screen or show them in one drawing
2016-05-14 add possibility to set own suffixes for polar, linear and cone picture export in the settings dialog
2016-02-25 fixes for the background of ais labels for 360° polar drawing, fix for drawing just lower polar distribution for files with upper ldt part
2016-02-12 background for axis label now transparent
2015-12-02 adapt font size in the batch export dialog to the same ratio as on the screen
2015-12-01 fix an error in legend routine which draws a not needed line across the diagram
2015-11-29 failure by choosing the right color in the polar diagram fixed. Additional planes did not use the color from settings dialog, now fixed.
(to fix just this, load the exe file)
2015-11-25 in the settings dialog you can now choose different font size for diagram axis labels and diagram legend, also possible is now selection of line type for grid, border width for curves, draw record date and fixture name
2015-10-05 choose between two different layouts for the datasheet. Additional you can choose which of the diagrams you want to have included, polar or linear or cone.
2015-09-05 change to Qt 5.5 and the QOpenGLWidget - classes, single read of ini file in different widgets is replaced by singelton approach
2013-11-13 adding handling of absolute values in photometric values for LED fixtures without separate lamp light flux -> LOR = 100% 2013-10-16 the positioning of some labels within the pictures is corrected and placed at the same position between cone, linear and polar
2013-07-26 A scaling problem in the datasheet exoprt ist corrected 2013-07-26 cone distance is stored in the indivdiual luminaire file *.ldtx and used also in the datasheet.
It adds features to batch convert ldt files to different picture formats.
It also adds the posibilitiy to show the light distribution in a 3D view and to create a basic data sheet for a luminaire.
Hope you have fun, Dietmar.
