我有一个我运行的自动剪辑脚本，作为它的一部分，我想拥有并选择将配色方案重新缩放为范围内的可见数据 - 布尔值。

我clipDisplay.SetScalarBarVisibility(renderView1, True)在Paraview 用户指南（第 10.1.2 章）中找到了此命令，并将其放置在剪辑的 paraview 跟踪脚本中的颜色转移函数的末尾。

运行脚本不会给出任何错误，但与在 GUI 中完成的相同操作相比，它不会重新调整配色方案。

我想普遍使用代码，所以手动选择具有数字定义的范围内的数据是不可能的......

使用跟踪你会得到：

#
# To ensure correct image size when batch processing, please search 
# for and uncomment the line `# renderView*.ViewSize = [*,*]`

#### import the simple module from the paraview
from paraview.simple import *
#### disable automatic camera reset on 'Show'
paraview.simple._DisableFirstRenderCameraReset()

# Rescale transfer function
pPWF.RescaleTransferFunction(-413.7960510253906, 192.35369873046875)

请问有什么想法吗？干杯

clip1Display.RescaleTransferFunctionToDataRange(False, True)是你想要的线。有关信息，在查找接口操作的 Python 版本时，您可以使用Trace( Tools/Start Trace)。它记录界面中的每个操作，当您停止 ( Tools/Stop Trace) 时，它会打印这些操作的 python 版本。

您无法轻松地在 python 中重新缩放到可见范围。

一种解决方法是提取可见数据以获取可见范围，最后将其应用于原始数据传输函数。这个宏可以解决问题


from paraview.simple import *
v=GetActiveView()
source=GetActiveSource()
SelectSurfacePoints(Rectangle=[0, 0, v.ViewSize[0], v.ViewSize[1]])# Or SelectPointsThrough 
extractSelection1=ExtractSelection()
# s=Show()
arrayInfo = e.PointData['X'] # replace 'X' by the array you want
r=arrayInfo.GetRange(0)
Delete(extractSelection1)
del extractSelection1
SetActiveSource(source)
ClearSelection()

pLUT = GetColorTransferFunction('X')
pLUT.RescaleTransferFunction(r[0], r[1])
