Re: Script BOY IntensityGraph to show areaDetector output of variable size

[Bruno Martins <brunoseivam@gmail.com>]

Hi Phil,

You can create two rules, for the data_width and data_height properties, that look at the $(P)ArraySize0_RBV and $(P)ArraySize1_RBV PV's

HTH,

Bruno

Thanks Gabriela,

- but I guess my question was ambiguous.  If I understand correctly, your script adjusts the height of the IntensityGraph widget so that its aspect ratio matches the image.

But the IntensityGraph will not display anything at all unless I set its Data Height and Data Width properties to match the attached array.  Do you have something to accomplish this?

Also: I have no idea how to actually attach the code or make it run at an appropriate time.  Can you point me at documentation that describes this?

Thanks

Phil

this is the very simple python script that I use:

from org.csstudio.opibuilder.scriptUtil import PVUtil

imageWidget        = display.getWidget('Image')
imageXSizeWidget   = display.getWidget('X-Size')
imageYSizeWidget   = display.getWidget('Y-Size')

try :
    imageXSizePV   = imageXSizeWidget.getPV()
    imageYSizePV   = imageYSizeWidget.getPV()

    nImageRows    = PVUtil.getLong(imageYSizePV)
    nImageColumns = PVUtil.getLong(imageXSizePV)

    imageWidget.setPropertyValue('graph_area_width', 512)
    imageWidget.setPropertyValue('graph_area_height', (512.0/nImageColumns)*nImageRows)

except :
    pass

Hi,

I'm using BOY IntensityGraph to show a (stdArray) output image from an areaDetector driver/plugin.
The size of my array changes quite a bit.
Can someone tell me (in laborious detail if necessary, please) how to set up scripts or "embedded rules" on the IntensityGraph to cope with a variable-sized image?

Thanks!

Phil
