Giles Atkinson 9773495e63 Fix Bug #624 - "Destroy All Fails with an Open Plot Window" for X11. 
Move XftDrawDestroy() call to a point where the window still exists.
 2023-02-25 15:42:41 +01:00
Holger Vogt 4f82a24df2 Add parameter 'isgrid' to plotting of arcs. 
Smithgrid and polar plots could not discern between xgridwidth and
xbrushwidth. This is now available, similar to straight line plotting.
Tested also for PS and SVG.
 2022-02-01 12:23:29 +01:00
Giles Atkinson 6494befb2f Request backing store for X11 plot windows. When supported by the X server 
windows are redrawn vey quickly without replotting.

Holger Vogt 1607b3a21f X11: Add a button for writing an SVG file to the plot window. 
Update button texts.
Add a function hardcopySVG to write the SVG file, called by
clicking the SVG button.

Holger Vogt 1919cf5c94 replace variable 'gridwidth' by 'xgridwidth' 2020-03-15 08:51:13 +01:00
Holger Vogt 93a408598a switch to colorarray in graph to string all color data, 
one set per each graph.
If we are zooming or selecting a cutout, copy the
source graph's colors to the new graph. Transfer the
old graphs id to the new graph via graph->graphid.
 2020-03-15 08:51:12 +01:00
Vogt 728ddae41e Set the color tables and linewidths personal for each graph, 
added to strucht graph
Use only these data for plotting.
If zooming a plot windows, set as an extra parameter the graph id
of the 'mother graph'. Copy its color and line data to the new graph.
This is done by an extra parameter sgraphid to the internal plot
command that is issued in fcn PlotWindowProc().
Thus zooming will keep the background, text/line and graph colors.
Function setcolor() will always look into the colorarray of the
current graph.
 2020-03-15 08:51:12 +01:00
Holger Vogt a7aaac854f enable color and font selection for X11: 
Add graphics context gridgc for plotting the grids.
Enable rgbd:, input of color by RGB 0 ... 255
If no color1 (text/grid) is given,
    select black or white according to backgrund color.
Error message, but no crash if font cannot be selected.
Enable separate linewidth selection for grid and graph.

Holger Vogt 38bb89663d replace old_x11 by HAVE_LIBXFT defined in configure 2020-03-15 08:51:09 +01:00
Holger Vogt bef9c70e71 Prepare font selection and rotation only once per graph 
in func X11_DefineXft().
Only 0 and 90 degree are supported.
