我有一个色彩图，它被优化用于从另一个程序（ncview）以准轮廓方式显示细节，我想在python图中使用它（使用matplotlib）
色彩映射文件是.h（colormaps_manga.h），它包含在：
static int cmap_manga[] = { 47, 55,159, 43, 52,160, 33, 43,162, 21, 32,163,

有没有办法导入这个？

以下是工作代码：
cmap_manga[...]
cmap_manga = np.array(cmap_manga)/255.0
ctmp = []
i = 0
while i < len(cmap_manga):
ctmp.append([cmap_manga[i], cmap_manga[i+1], cmap_manga[i+2]])
i += 3
mangacm = ListedColormap.ListedColormap(ctmp, name='manga', N=None)
感谢您的帮助frits =）

可能有几种方法，但这可能有用。 重新组织您的数组并使其成为色彩映射：
cmap_manga[...]
ctmp = []
for i in range(int(len(cmap_manga)/3)):
ctmp.append([cmap_manga[i],cmap_manga[i+1],cmap_manga[i+2]])
# Create a new colourmap from the ctmp array
mangacm = ListedColormap(ctmp,name='manga',N=None)
（我没试过......）
