Hi,
Recently,I find that in the example spectrogram,it use QwtLinearColorMap and use the function
QwtLinearColorMap::addColorStop,but if I want to init the colormap from my file f.e *.map, how can I achieve such effect?
In *.map,data like this:
0 0 255
3 1 252
5 1 250
8 2 247
10 3 245
13 3 242
15 4 240
18 4 237
20 5 235
23 6 232
26 6 230
28 7 227
31 8 224
33 8 222
36 9 219
38 10 217
41 10 214
43 11 212
46 11 209
48 12 207
51 13 204
54 13 201
56 14 199
59 15 196
61 15 194
64 16 191
66 17 189
69 17 186
71 18 184
74 18 181
77 19 179
79 20 176
...
maybe 100 lines in total.
Thank you.
