Cosmetics, code clean up.
AIS_ColorScale now draw labels using Graphic3d_VTA_CENTER
vertical alignment flag, instead of incorrect own alignment logic.
The color bar now adds margin on the top simmetrical to the bottom.
AIS_ColorScale::SetSmoothTransition() - added new property
for displaying colorscale with smooth transition between color intervals.
AIS_ColorScale::SetHueRange() - added new property defining the hue angles
corresponding to minimal and maximum values on the color scale.
AIS_ColorScale::SetLabels() now allows setting the sequence of free labels,
which number does not match the number of intervals.
In this case the labels will be displayed at positions of virtual
intervals corresponding to the number of labels.
Interface of AIS_ColorScale is revised to make it more consistent:
- Methods SetBgColor()/GetBGColor(), and corresponding field, are removed. It was used to select white or black color for the color bar frame (by contrast). That color can now be set explicitly by inherited method SetColor().
- Own methods Get/SetColor() are renamed to Get/SetIntervalColor(), to avoid confusion with inherited method SetColor()
- Methods Get/SetWidth() are renamed to Get/SetBreadth(), to avoid confusion with inherited method SetWidth()
- Method Get/Set for labels and colors, and DRAW command vcolorscale, now all accept index starting at 1
- Comments added to explain indexation rules
Color scale is implemented on AIS. Draw command vcolorscale now works with AIS_ColorScale.
In a qt sample VoxelDemo there was added a field AIS_ColorScale myColorsScale to control a color scale. Method displayColorScale and other methods were changed in order to work with this field.
Update documentat if the class.
SetColor() and SetLabel() now work with 0-based index.
SetColor() now checks length of myColors.
Remove methods GetCurrentColor() and GetCurrentLabel().
Methods GetColor() and GetLabel() now can be used to get user-specified and default colors / labels.
Round down IntervNumber in FindColor().
DrawScale() - show labels even for one interval.
Redesign Draw Harness command vcolorscale, provide new options.
Update test cases which use vcolorscale command.
