Apply contrast settings to updated image data

[Nikolai Mikuszeit]

Hi,

I am using the example for ContrastAdjustments to analyze/manipulate some
data.
To apply the changes upon manipulation I use the set_data() method. I want
to apply the same contrast levels adjusted for the previous image.
Without docu and after hours of scanning the API I found a solution
presented below (in red). I am, however, not really satisfied with this. Is
there a better way to put the present contrast adjustments to an image
after image.set_data()?

for toolklass in (VCursorTool, HCursorTool,

self.win.add_tool(toolklass)

self.contrastPanel = self.win.get_contrast_panel()

self.contrast_min,self.contrast_max=self.contrastPanel.histogram.range.get_range()

self.image.set_data(data)

self.plot.replot()
self.contrastPanel.set_range(self.contrast_min,self.contrast_max)
