Image Control and URL

I defined an image control with an Action of URL specified.
When I specify a URL that points to a location with spaces in it, the URL is encoded, but VC replaces the spaces with + instead of %20. I tried many variations to get it to not encode and/or encode differently, but to no avail.
How can I specify a URL that includes spaces in it for an image control?

Hi,
Could you try with images that don't contain spaces?
If it works, you could change the specific image name as to not contain spaces.
Best regards,

How to use an Event Structure responding to an image control that belongs to a parent VI.

Hi
I am loading a subpanel vi by pressing a button located in the user interface of the main vi which also contains an image display. Subpanel vi opens up on the side and doesn't hide the image display of the main vi. Subpanel vi contains an event structure that needs to respond to user clicking on the image display of main vi.
Since the bug that occured while creating an image reference control isn't fixed, I am passing the main vi pane reference onto the subpanel vi. From that point I've tried to edit event structure and have it respond to the image control/pane that belongs to main vi but I don't know how.
Any help would be appreciated.
Thanks

Post a screenshot of your subVI code where you register the events.

Open a disk image file and crop it to an Image control

Hi Folks,
I am trying to allow my users (in a browser) to select/open a disk file (image type) so that they can see it and then save it to the server. I can use the FileReference object just fine, and load its 'result' directly into a MX:Image control. However, before I do that I would like to crop the selected imaged to a square shape. I'd also like to resize the image down, but that will come later, once I get the cropping working.
I am essentially taking the FileReference result bytearray and converting that to a BitmapData object. Then, I 'extract' a square of data from that BitmapData object into a new BitmapData object. Then I need to get *that* BitmapData object into the mx:image control. I tried using a Bitmap to do so, however the resulting mx:image, while 'sized' correctly, displays as a blank white region. All along, the variables seem to be 'full' of data and seem to have properly set attributes. I've looked up quite a few sites that demonstrate cropping, and copying images, but they always start out with 'pre-loaded' images. I have modeled my code after theirs, where appropriate.
Here is my code:
          //this gets called when the user clicks a button to 'look for a disk file'
            private function setPhoto():void
                //create the FileReference instance
                _fileRef = new FileReference();
                _fileRef.addEventListener(Event.SELECT, onFileSelected);
                //listen for the file has been opened
                _fileRef.addEventListener(Event.COMPLETE, onFileLoaded);
                var arr:Array = [];
                arr.push(new FileFilter("Images", ".gif;*.jpeg;*.jpg;*.png"));
                _fileRef.browse(arr); //then let go and let the event handlers deal with the result...
            private function onFileSelected(evt:Event):void
                _fileRef.load(); //the result of the 'load' will be handled by the 'complete' handler
            private function onFileLoaded(evt:Event):void
                var tempLoader:Loader = new Loader();
                tempLoader.loadBytes(_fileRef.data);
                tempLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaderComplete);
                //imgPhoto.source = _fileRef.data; //this would work just fine, though, it wouldn't be cropped
            private function onLoaderComplete(event:Event):void
                var loaderInfo:LoaderInfo = LoaderInfo(event.target);
                var loadBD:BitmapData = new BitmapData(loaderInfo.width,loaderInfo.height);
                //ok, now that we have the 'original' file in the bitmap data, we can crop it and then later resize it
                //so, we need a 'square' of image cropped out of the original
                //so...first we get a square of the 'full size' image
                //if the image is taller than wide, we will take a square as wide as the image, and as tall as it is wide, starting 5% down from the top
                //if the image is wider than tall, we will take a square as tall as the image, and as wide as it is tall, from the horizontal middle
                var curW:int = loadBD.width;
                var curH:int = loadBD.height;
                var cropX:int = 0;
                var cropY:int = 0;
                var cropW:int = curW;
                var cropH:int = curH;
                var needCrop:Boolean = true; //default is to crop
                var croppedBD:BitmapData;
                if (curH > curW)
                    cropY = Math.round(curH * .05); //start at 5% down
                    cropH = cropW;
                else if (curW > curH)
                    cropX = Math.round(curW/2) - Math.round(curH/2); //start at the middle, go 'back' by half the height
                    cropW = cropH;
                else
                    needCrop = false; //it's already a square! nothing to do (aside from the resize)
                if (needCrop)
                    croppedBD = new BitmapData(cropW, cropH); //at this point it is 'empty', so fill it up
                    var fillPoint:Point = new Point(0,0); //since we're gonna fill into the top, left pixel on down and over
                    var fillRect:Rectangle = new Rectangle(cropX,cropY,cropW,cropH);
                    croppedBD.copyPixels(loadBD,fillRect,fillPoint);
                else
                    croppedBD = loadBD;
                imgPhoto.source = new Bitmap(croppedBD); //this produces a properly sized, but blank-white image
And here is the mxml for the image:
<mx:Image id="imgPhoto" x="40" y="126" maxWidth="200" maxHeight="200" />
Thanks!

Hi,
You were close to the solution.
In "onLoaderComplete(event:Event):void", at the begining you create a BitmapData called "loadBD", you just forgot to fill it with the content from the loaderInfo.
private function onLoaderComplete(event:Event):void {
     var loaderInfo:LoaderInfo = LoaderInfo(event.target);
     var loadBD:BitmapData = new BitmapData(loaderInfo.width,loaderInfo.height);
     loadBD.draw(loaderInfo.content);
Kind regards,
Mich

"Type mismatch" error in IE7/8 when using custom Actions Menu Image

Hi all,
in APEX 4.2: when using a custom image in the "Actions Menu Image" attribute in an interactive report, I get a "Type mismatch" error in IE7/8 when refreshing the report through PPR (filtering, sorting, paginating etc.). When I leave the "Actions Menu Image" field empty, everything works fine. The error doesn't seem to happen in IE9 (unless using compatibility mode), or in any non-IE browser.
I've been able to reproduce the issue in an application on apex.oracle.com:
http://apex.oracle.com/pls/apex/f?p=69347:1
Some debugging seems to indicate that the following line in widget.interactiveReport.js is the culprit:
lTemp.parentNode.replaceChild($x('apexir_WORKSHEET'), lTemp);Does anybody know if this is a known issue, or if there is some workaround?
Thanks,
Tobias

Hi,
Great solution Paul! It cost me a while before I found out the Action Menu Image was causing my interactive reports to stop refreshing in IE10 and not other browsers. Your solution works great, I've implemented it with a few minor adjustments:
- Put the css in report template (for some reason it didn't work in our own application stylesheet)
- replace 'url("/c/action_dropdown.gif")' with 'url("&APP_IMAGE_PREFIX./<path_to_image>")'
- place one dynamic action on page 0: after refresh of '#apexir_DATA_PANEL' , set event scope to "Dynamic".
- Let the Dynamic action also fire on page load.
- To make sure the dynamic action only works for pages with an interactive report add condition of type 'Exists' with expression:
select 1
from   dual
where :APP_PAGE_ID in (select page_id
                                        from   apex_application_page_ir
                                        where application_id = :APP_ID

Thank You Mathan MP,
i tried these steps, but whenever i selected the source property of image UI control, it opens a context window, but this context window does't contain any thing for selection.
so how to solve this problem ?

Image not displayed correctly in image control at small zoom level

I am displaying an image in an image control with a zoom factor of ~0.015 and it appears as shown in image 1.jpg. When I zoom in a little more to ~0.016 the image is displayed correctly as shown in image 2.jpg. Both images are attached.
Why is the image displayed as a "grey strip" in the first image? What do I need to do to have the image displayed correctly at any zoom factor? I am using LV 2011 with the associated vision development module on Windows 7.
Thanks,
Jonathan-LV

Hi Jonathan,
Did you try resizing your image dimensions, as I suggested in my previous post? Anti-aliasing is an expected behavior; as you zoom out, the image has to be resampled in order to be displayed properly. At some point, LabVIEW assumes that the image has been resampled to the point where it no longer resembles the initial image, and so it greys the image out. In the case of your image, that is not the case. As I said, I believe an acceptable workaround would be to use IMAQ resample to half or quarter the pixel dimensions of your image, at which point it should be able to be displayed at a higher zoom factor.

Some images not loaded in flex Image Control.

Hi,
Can anybody help me. I am loading friends album image in flex Image control. Its strange that some image do not load even the path is fine and I can open in browser. I think there is time out issue.
Thanks in advance.

Hi premkant81,
Try to register the following event Listeners and try to trace out the problem...
I hope you are using either Loader or URLLoader to load the images...Try to register the below eventListeners for the Loader..and check
HTTPStatusEvent.HTTP_STATUS
SecurityErrorEvent.SECURITY_ERROR
IOErrorEvent.IO_ERROR
What is the size of the Image files you are loading...???
Thanks,

Labview 2012 image control freezes in executable

Hi there,
I've put some Image controls on the front panel. On the development system, the background is grey and the ROI tools responsive.
The executable howeve, has black backgrounds and the image control is not responsive any more.
LV 2012, Windows 7, 64 Bit. It does not matter if the file is compiled on a server or locally.
Sometimes the compiler fails because of "file permission errors". If not, the problem still persists.
What do I do wrong ?
Best regards,

Hi there,
I forgot to tell that it's not possible to load any images into the control.

Vision Builder 7.0(IMAQ) : Using fxs in subVIs with references to image control

When using IMAQ fxs (such as 'Write File') in subVIs, if one wanted to use references to an image control, what property or method would be used to feed into the image terminal in the imaq fx on the subVI? Is this possible?
What did work: I was able to directly use the image control on the main feeding an image control on the subvi panel (which is then fed directly to imaq fx)
What did not work: From a refnum control for the image on the main, I used (within the subVI) the value property fed to a 'Variant to Data' with type as image control, then feeding the output of this into imaq fx.

Typically you would update an Image Display control from a subVI using the Value property nodes. However, this method does not currently work with LabVIEW 7 and Vision 7, but the issue will be resolved in the next release of LabVIEW and Vision.
In the meantime, in addition to the solution you found you could also use a global variable to pass images from one VI to another. Using a global variable works, but not in the same way as a reference or property node would. With a reference or property node, you can pass a reference of the control to a subVI and have the subVI update the control's image. Using global variables, the subVI will update the global variable with the new images, but you need a loop monitoring the global variable in your top level VI.
I hope this
helps! Best wishes.

Flash movies in image-control

When I load different flash movies in the same image-control
(e.g. via a button-click), the browser-cursor starts switching from
a busy-cursor (the little round clock-cursor) to an arrow (or
hand)-cursor intermittingly, without stopping.
When I load the same movie over the existing one in the
image-control this does not happen.
Seems like I have to unload the old movie first? I don't know
how to do that.
Any suggestions are welcome.
Thanx in advance.

Image control source attribute

I would like to protect my source files such as images from being downloaded or directly referenced by a URL by somebody other than my program. I thought may be an easy way to do that would be if I set the source to outside my webfolders. But my understanding is that in an Image control, the value of the property source has to be under my web root folder. Is there a way I can set the source to outside of my web folder and still have my flex app render the image od does some one have a different way of achieving the same objective. Thanks, Ramesh

Hi there
You can embed your image on the application.
On FlexBuilder project, add a new source directory with your images... and in your source code some like this:
<mx:Script>
<![CDATA[
[Embed(source="image/yourImage.png")]
[Bindable]
public var myImage : Class;
]]>
</mx:Script>
<mx:Image source="{myImage}"/>

Image control runtime creation issue

I am having problems getting the Image control to actually
display the image I specify in the source property. The Image
control is created in actionscript at runtime based on XML returned
by an HTTPService request. I have a canvas that I want to populate
with Label, Text, Image, LinkButton, etc. controls based on the
contents of the XML file that is read in, so I have to create all
the components on the fly and use something like this:
var newImage:Image = new Image();
newImage.setStyle("source", "images/myImageFile.jpg");
myCanvas.addChild(newImage);
After I get all the newly created components added as
children to the canvas I go back through and do positioning
(something like this):
for each (var child:DisplayObject in myCanvas.getChildren())
//set the y property of each component to the y of the
previous child plus
//the height of the previous child plus 10 px margin
Wherever there is an image in my XML it inserts the 10px
margin for that component, so I know it's creating it and that it
gets added as a child, but for some reason the image is not
displaying and so the height of the component is 0. I even tried
hardcoding the height of each Image control in case the image was
there but it just wasn't sizing right, but it puts in the space
without displaying the image.
What I'm wondering is if there is some method that will force
the Image controls to either load the image or render it. When I
add an Image in mxml and use the exact same source data it displays
just fine, so the file path is correct. I also have the same images
being read in from XML off the HTTPService that are showing up just
fine in a TileList where my itemRenderer component has an image
with the source set to the same path as I'm trying to use in the
runtime-generated Image controls.
Also, as a side question, does anyone know why a lot of the
properties/methods available from mxml specified comonents aren't
available when you create variables of the same type in
actionscript? For example, if I have
<mx:Image id"img"/>
I can go back in actionscript and reference img.source just
fine. On the other hand, if I declare an Image in actionscript,
thus:
private var asImg:Image = new Image();
and then try to refer to the source property like so:
asImg.source
it doesn't show up in the code hinting and it also throws an
error on compile (reference to a possibly undefined property source
for bla bla bla)
Actually, I've noticed that a lot of the properties and
methods of various components aren't available when they are
actionscript rather than mxml. I didn't see much in the
documentation on the difference or what could be done to work
around it.
Thanks much anyone who has input.

Ok, got it.
I figured that since the <mx:Image> renders just fine
and that the ActionScript Image object doesn't that I'd just create
a custom mxml component with Image as the base element and with
nothing else in it. Then I add an instance of my custom image
component in AS whenever the XML specifies one. The layout was a
bit of an issue, but I just added the image dimensions as
attributes in my XML and size the CustomImage component based on
those.
Must be some subtle difference between the mxml and AS Image
classes that isn't documented very well.
