saving color map from intesity graph to jpg

[eruvi]

Hi to all..

I have 2D array ( of numbers) and I use intensity graph to convert the numbers to a color map.

But I want to save this color map to jpg file (as image.. )

How do I do that?

Thanks

A very similar question was asked and answered here just a few days ago:

Gotta love that "Search" feature,

But I need Intesity graph ( for every x,y position I have a value ). not XY graph..

Thanks

In the afore-mentioned post, I described two methods of getting a JPG image of an XY Graph...one method was specific only to Waveform Graphs and XY Graphs (the "Export Image" method), while the other method I described ("Get Image" method and Graphics Formats VIs) will work for any control type.  So again I say, use the "Get Image" method to get a flattened image of the Intensity Graph, then use the Graphics Formats VIs to save that flattened image to a JPG file.

Good luck,

First,thank you very much.

But the problem is that I don't want to save the background of the graph ( e.g.  legend , graph frame)

I want to write to the jpg file only the image within the intensity graph.

In that case, I would make a copy of the Intensity Graph, and deselect every option under the "Visible Items" right-click menu.  At that point, all that should be left would be the gray frame of the Intensity Graph.  At this point, you can use the Paintbrush Tool, right-click on the gray border, and choose the 'T' in the color picker to make it transparent.  At this point, your Intensity Graph should only show the colored graph region and nothing else.  Then you can use the method I described to export the image to disk.  I have attached a screenshot of a front panel of a VI with an Intensity Graph with all parts other than the graph region made non-visible.

Hope this helps,

hi.. mr Darren

 i do not think the way you have told will work..

i think it can be done by flattening the image and then write to jpg image method..

can you please post the vi indicating what you actually want to say or do?
