Control picture

[aSquared]

Hi , (I use LV 8.2.1)

I want to create a picture as an object on the Block Diagram, So I can control her.

(of course, I want to see her on the Front Panel. But if I drag her or import her to the Front Panel there is no corresponding object of the picture on the Block Diagram)

I have seen the way it works in the example : 'Picture Control - Zoom Attribute.vi'

(Using the 'Draw Flatten Pixmap.vi' with adding an empty picture and describing the image data as an input cluster to get the desired outputted picture)

but I don't understand how to create the Image Cluster information, specifically the arrays (of image mask and colors),

regarding a different picture that I have.

I think I can use some Matlab function such as IMREAD and write the data to a text file and then read it through LabVIEW,

but there must be an easier way...

Or maybe there is a different common way to achieve a controllable picture object ?

Sincerely Yours,

Amitai Abramson.

The picture control VIs do this and there are probably some example in the example finder (Help>>Find Examples).

You can also find some more advanced uses of the picture control here.

Now, time for some ceremonies...

Yesterday Morning I had a ceremony at Work. 

Yesterday evening I had a ceremony at Kfar Edumim.

Today I had a ceremony at Hertzel Mount. in Jerusalem.

Enough with the ceremonies...

Now it is time to celebrate.

I haven't found the Vi's (that do what I asked) earlier, I will look for them now

Thanks. 

Amitai.

Hi again,

I am sorry, but I couldn't find how to create a picture as an object on the Block Diagram.

All the functions on the Picture Function Palette are assuming that the picture (a jpg/png) file is an object at the Block Diagram,

(they have an input 'picture')

Please show me, if You can, how do you create a picture object on the Block Diagram, from a given picture file,

For example the 'clouds.png' file that is attached.

If I understand you correctly, all you need are Read PNG and Draw Flattened Pixmap functions.

Hi,

From tst's answer, I got the idea that it is simple.

But still, from some reason, I haven't found  the Graphics Formats Palette, So I can read a picture file.

Sorry tst and Dennis, my bad.

Hi Amitai,

This is where it is located in LV 8.6.

Yours should be about the same place.

You can also use the 'Search' function.

I guess that I am not so good at expressing myself...

What I meant to say in my last message was that I found the Palette,

and I have apologized to tst and Dennis for asking a trivial question.

When I asked - "how to read a picture file" when there is a unique palette for that matter.

Thank you all for your help.

Many non-native English poster here will post their Q is both languages.

Fell free to do so. It will help you get you Q answered and some of us will get a kick out of trying to learn anothe language ourselves.
