View Aquired Image in a Tab control

In order to conserve space I would like to view a live image, aquired from a 1409 board,in a page of a tab control. Also to decrease cpu usage I have set up a Low Level ring. I have tried sending the image to a picture control, but the image is choppy (even if I slow down the loop). My image is perfect in a Vision Window, but this cannot be used as a control on a page. Any suggestions?

Terry,
Bruce has the right idea, try making a child panel and use WindShow to hide or show the display....Attached is an example I wrote using multiple boards and displaying two images on the pages of a tab control...I hope this helps.

Export image EMF from tab control, help!!

Hello,
I am trying to get a good resolution report. I got use export image to EMF file so the graphs look very good resolution. When I appended the image control like png it looked poor quality. Now is ok, now I export image of graphs to emf and then use 'append image to report' using the path of file emf.
But I have a problem in this case. I am trying to get EMF file from Tab control. I have 8 graphs inside of each page of tab control. I would like to get each page exporting to EMF file and later append the image to report from path of file. The problem is I cant export to emf. I tried the solution in this treads.
http://forums.ni.com/t5/LabVIEW/send-control-image-programmatically-to-clipboard/td-p/180921/page/2
But it uses get image and it is bmp, so no good solution.
I attached pdf file. IT shows the tab control with append control to report (it is like capture in png file) and one graph append control to report png and emf file of another graph and use the path to input in word report. You can see the diference.
I would like to know if i could export the tab control to emf or any onther vectorial image and later use the path. SInce it will take several pages and i will need sometimes 300-400 graphs...
Any idea would be great.
Best Regards.

Hi Mike,
Thanks for your reply!.
Well, it was only one example. Check the attached file. It works ok. I split in dataset of 8sec and save the emf files.
The problem is the report. If I enable it doestnt works fine, since you will be the both parts working in the same time.
That's why the sequence structure would be ok, one time all the graphs are saved then I could append to report.
I have another question. I used transparent graph and it works ok. I remove all the scales Y values or labels and customized the graph adding one horinzontal line for X scale (like capture), but in the file emf saved didnt appear. Do you know why?.
Best Regards, Fred.

Background image tab control

i use labview 8.20
is it possible to add a background image to a tab control ?
i only see, that i can change the color. or change the background image from the complete background.
but i dont't want to make my tab control transparent, because then i can't see the registers (tabs with the text) of the tab control.
is there a solution ?

I do not believe that you can do it directly. You could add a picture control to each tab and place it behind the controls and indactors to achieve the same effect.

Programatically Change Tab Control Image

Is it possible to change the tab image of a
tab control using program calls? I can add an image to a tab by
right clicking the tab, then selecting Advanced --> Tab Layout
--> Import Image From Clipboard. This works well when editing
the VI, but I would like to change the image while the VI is
running. Any help?
I have found no resources online, or by looking at the property node or invoke node for the tab control.

Not possible. The image can only be set while in edit mode.

Thanks Gita_A.
I have attached the relevant part of my program. It's not to do with the size but position of the image - I would like the image to be right in the centre of the tab control.

How do I view multiple images in one window?

How do I view multiple images in one window? I want to compare images side by side, not in tabs.

Thank you, Barbara. I found that I had to close the program after I turned on "allow floating documents" and restart, before I was able to go to "float all in windows".

Can you print all the tab control's contents and include the tabs?

We are trying to generate a report that includes the contents of a tab control (graphs, text). Using the Append Control Image to Report.vi, we are only able to print out the active tab and the tab is cut off of the image. How can we generate reports that include all the tab pages and their contents and include the labeling tabs?
Thanks in advance.
Jim

I do have a workaround for makinging the prints but it looks like some sort of cropped screensave that cuts off the tabs. In my sample I was printing out 3 of the tab controls and you can see there are three by the cut off tabs. Is there a setting to allow for more of the graph and its surroundings to be "captured"?

Horizontal tabs when they are on the left side of tab control

I have a tab control for a touch screen where I was going to use buttons along the left side to change tabs, and hide the tabs. However, I realized I can put the tabs on the left side of the tab control and remove my buttons all together. Only issue is, I would like them (along with their font) to be horizontal, not vertical as they are shown in my screenshot. Is there a way to change this?

It's a really poor design aspect of tab controls that the text is sideways when the tabs are on the left or right side.
I've looked into it and found no way to re-orient the text.
However you can put images on the tabs instead of text, and the images can be of text (correctly oriented of course).
The attached code can be used to generate such a tab control.

Cannot view certain images

I cannot view certain images, and I have already checked my settings a few times over. This only occurs occasionally with deviantart. Previously I came across a way to correct this, but it's been so long now that I've needed to adjust it that I've forgotten. So my question: Is there a way to adjust things so that the differently sized images appear regardless of pixel amount? It tends to be either only the preview or fullsize image on DA. Also, though I've Adblock Plus now, this happened even before.
== URL of affected sites ==
http://deviantart.com

It is possible that you accidentally clicked the 'Block Images' item in the right click context menu while trying to save an image.
Check the image exceptions: Tools > Options > Content: Load Images: Exceptions - See [[Options window - Content panel]]
A way to see which images are blocked is to click the favicon (''Site Identification'' icon) on the left side of the location bar and click the "More Information" button.
This will open the Security tab of the ''Page Info'' window (also accessible via Tools > Page Info).
Go to the ''Media'' tab of that Page Info window.
Select the first image and scroll down though the list with the Down arrow.
If an image is grayed and there is a check-mark in the box ''Block Images from...'' then remove that mark to unblock the images from that domain.

Hi ViswAmmu,
>>Please help me out to get transparency for path in canvas to view background image in canvas.
If I'm not misunderstanding, I think you just need to loop through all Canvas.Children and set Opacity property for them:
private void Image_MouseLeftButtonDown_1(object sender, RoutedEventArgs e)
//Loop through all children items
foreach(UIElement v in CanvasPanel.Children)
v.Opacity = 0;
op.Title = "Select a picture";
op.Filter = "All supported graphics|*.jpg;*.jpeg;*.png|" +
"JPEG (*.jpg;*.jpeg)|*.jpg;*.jpeg|" +
"Portable Network Graphic (*.png)|*.png";
if (op.ShowDialog() == true)
ib.ImageSource = new BitmapImage(new Uri(op.FileName));
imgBackground.Source = new BitmapImage(new Uri(op.FileName));
CanvasPanel.Background = ib;

Tab control with 2 pages

I want to create a Tab control with 2 pages, in each page there are 2 buttons - "OK" and "Cancel".
If on Page1, "OK" is clicked, Page2 will be disable and greyed, until "Cancel" is clicked. And vice-versa for Page2 buttons.
How to do this?
Thanks in advance...

Hi Splee,
Please view the attached vi, I believe it's doing what you've asked. You can invoke properties using property node in order to change the value of variables.
Hi Simply_me check your Vi will it really works. To make this VI in working condition you have to do some more coding in your code.
Check your page selection technique.
Hi Splee,
First you have to find out on which Tab Page user clicking the buttons, the all operations you have to do on other page.
Once your page is disable you can't access the controls of that page. As Geeta says make a code using event structure with Tab Control property and invoke nodes.
You have to do some coding to achieve your requirements.

How do you change a background image in an HBox control via actionscript?

Hi All,
I would like to change the background image of a HBox control
when the user clicks on a tab (tabnavigator control). I call a
function on the 'activate' method of a VBox control, within the
TabNavigator. So for each of the tabs when a tab is selected an
appropreate image is displayed in another part of the screen.
Thanks for any insights/help
regards
Davej

Binding a string variable and using the show() event instead
of the activate event will work. See Below
<mx:Script>
<![CDATA[
[Bindable]
private var mystring:String = new String();
private function dispAssocIMG(f3rd:String):void {
mystring = f3rd;
]]>
</mx:Script>
<mx:HBox backgroundImage="{mystring}" id="first3rd"
width="567" height="336" y="209"></mx:HBox>
<mx:HBox id="mid3rd" width="457" height="336" y="209"
x="567" backgroundColor="#956944">

<mx:TabNavigator height="336" width="457" >
<mx:VBox label="about me"
show="dispAssocIMG('image1.jpg')"></VBox>
<mx:VBox label="test2"
show="dispAssocIMG('image2.jpg')"></mx:VBox>
</mx:TabNavigator>
</mx:HBox>
</mx:Application>

How to view an image @ 100% ?

When I do some editing in iPhoto, especially sharpening, I'd like to see it @100%.
There is no indication at what % I'm viewing the image.
Is there any way to know that ?
When clicking "edit" on the bottom, at what size the image opens?
Thanks!

ok, I found an Apple article from 2007 which explains how to do that. I'm posting it here for others:
===================================
iPhoto: Sharpness adjustment may not be apparent when viewing at less than 100 percent
Last Modified on: July 13, 2007
Article: 301425
When you view an image at less than full size, iPhoto smooths it (a technique known as anti-aliasing) to get rid of artifacts that result from scaling down the photo. The relationship between anti-aliasing and sharpening is a trade-off; although anti-aliasing does not modify the actual image file, it does counter the effect of sharpening when viewing the image at less than full size.
Because of this, if you sharpen a photo, close it, then reopen it again at a less than 100-percent view, you may get the impression that your sharpness changes were not saved. In reality they were, but since the image has been re-aliased to fit your screen, the image's true sharpness may not be apparent.
To evaluate whether an image is sharp or needs sharpening, you should view the photo at 100 percent/full size while editing in a separate window. To open the photo in a separate window, you can either Control-click the image and choose "Edit in a separate window" from the shortcut menu, or change your iPhoto preferences:
From the iPhoto menu, choose Preferences.
In the General pane, locate the preference for "Double-click photo."
Set the radio button to "Opens photo in edit window."
Close the preferences window.
Now photos will open in a separate window when you double-click them. Once in the separate window, choose 100% from the Size pop-up menu. If you don't see the Size menu, widen the window until it appears.
Tip: If you are editing the photo from one of the other view options, you can press the 1 key to quickly jump to 100 percent view.
Other applications, such as Adobe Photoshop, handle anti-aliasing differently, so the degree of apparent sharpness can vary from one application to the next when viewing an image at a scaled-down size. You should see consistency when comparing the image at 100 percent across other applications.

Hi,
Aaa.. the blue box is an Enumeration Constant. Because I've used something like this you cannot change the name of the Tabs. To fix it:
Simply replace these two Constants with Numerical Integer Constants 0 - for the first Tab and 1 - for the Second Tab. It took me a while to understand what you wanted to say . This way you can change the name without getting an error.
I've rewritten the entire VI in order to be clean (I was ashamed of the previous one). You can still use the first one.
Just an advice: Even if it looks at the beginning more complicated try to use Event Structure all the time when you have buttons. The use of loops with buttons and if structure (like in your vi) creates a lot of problems and it's hard to debug.
