Dynamic Image Display

I'm trying to display an image in a report region based on external table information and I'm unable to figure out how to make the image render. I've looked at previous threads and I'm still confused!
Situation:
I am display a report about an object selected by the viewer; I've successfully displayed the various textual entries about the object. Now I'm trying to add an image to the report. I have a table containing the textual entries and two columns about the image: a BFILE column and a FILE_NAME column. The file is a jpeg image of the object described by the report. I've examined the sample code in the HTMLDB sample application which deals with "direct images"; I've tried to adapt the code to work for a BFILE entry. However, I don't understand how to "translate" a BFILE & FILE NAME combination into a "src=" entry for display.
A couple of threads indicated it was a simple matter to adapt to a BFILE entry, but evidently I'm out to lunch! Would appreciate some basic help.

Hi George,
Sounds like an interesting one....
You could certainly use a BFILE, the thing to remember (as Vikas mentioned) is that the filename used for the file is not necesarily the same as the URL that should be used for accessing the file over the internet.
What I mean by this, is you will store the files on the filesystem somewhere (say for example '/work/images') you will need to make sure that this directory is accesible by the webserver (so, for example 'http://myserver/workimages'), then using the filename for the file you will append that to the base URL used for accessing the images (e.g. 'http://myserver/workimages/myfile.jpg')
So in your SRC parameter you would use the URL (and not the actual filesystem path), you could use either a full URL (e.g. 'http://myserver/workimages/myfile.jpg') or a relative path (e.g. '/myimages/myfile.jpg').
The key is to make sure that the directory your images are stored in is accessible by the webserver, once you manage to do that then the rest is (relatively) easy.
Also since you mention versioning and archives of the images, I'd be tempted to investigate storing the images in the database (therefore you can easily maintain the 'history' for the image) and you could also write an upload/download routine so that the image can be downloaded for editting with Photoshop etc, then uploaded once the user is happy with the results. This would also have the benefit that it would be relatively easy for the image to be 'checked out' by a user ensuring that no two people were working on editting the same image at the same time (if that was a business rule).
Hope this helps,
John

Dynamic image displays depending on yes / no value

Dynamic image displays depending on yes / no value
I´d like to have a image showing, depending on a specific value (y/n)
..sorry need some help.
I can´t get it workin.....
<img <?php $status="n";
if ($status == "y") {
echo 'src="stecker_on.png" alt="yes"';
} else {
echo 'src="stecker_off.png" alt="no"';
} ?> height="71" width="101" />
The image ist not showing... ideas ?
All I get ist some text showing:
height="71" width="101" />
MANY THANKS !!!!

Presumably you mean this -
http://mediaconsults.de/1test/steckertest.php
And it's not clear what that is going to show me. Looking at the code on the page -
<html>
<head>
<title>Unbenanntes Dokument</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="JavaScript" type="text/JavaScript">

<body background="test%20png.png">

</body>
</html>
I would advise you the following:
1. Put a valid and complete doctype on that page!
2. Get rid of the resize if NN4 javascript - it hasn't been needed for nearly a decade.
3. Fix your image code (note the missing space after "no"!
4. 1290px is way too wide unless you want lots of people scrolling right to see things.

Dynamic Image Displays Blank When Using In Visual Studio Project

I am trying to simply display a dynamic image in a report. I am using Crystal Reports XI Release 2.
I have two different environments: Local via Progress where reports are called using Crystal Viewer ActiveX, and over the web where reports are called from Open Laszlo and Visual Studio project.
The image is set to a blank image as default, and Graphic Location Forumla loads the image from the database (site.logo_location + site.logo_filename) which results in an image http:
www.vetinfo3.com\a.jpg.
When I run the reports locally using the ActiveX control, it works just fine and displays the image.
When I run over the web using OpenLaszlo, it displays a blank.
Troubleshooting
We are using Visual Studio 2005, which is bundled with an older version of Crystal that doesn't support dynamic images.
To address this, I loaded Crystal XI Release 2, which updated the version in Visual Studio and enabled the Graphic Location formula field on the dev machine.
I verified the Graphic Location field was set correctly.
This caused a Version error, so we loaded cr_net_2005_mm_mlb_x86.zip on server and specified the Version in web.Config.
No errors now, but when I build and publish the code, the image still displays as blank.
            From Fiddler
               GET http://www.vetinfo3.com/mdsol1/CrystalImageHandler.aspx?dynamicimage=cr_tmp_image_c5d6a923-293b-4f1e-8739-4e698f83b087.png
               Creates C:\Documents and Settings\Curtis\Local Settings\Temporary Internet Files\Content.IE5\PWRUX2XW\CrystalImageHandler[1].png
               Blank Image
According to issues within Visual Studio, they say the fix to this is to add the <httpHandler> in web.Config, but it is already there; added when we add the viewer to the project:
In web.Config I have some questions about this line:
    <httpHandlers>
      <add verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=11.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
    </httpHandlers>
There are more service packs for Crystal XI Release 2:
crXIr2sp2_net_server_install.zip
crXIr2sp3_net_server_install.zip
crXIr2sp4_net_server_install.zip
I have not loaded these yet, but the readme files do not indicate they fix any dynamic image issues.
I am out of ideas on this; does anyone have any ideas?

What about if you take OpenLaszlo out of the picture? E.g.; use one of our samples from here;
https://wiki.sdn.sap.com/wiki/display/BOBJ/CrystalReportsfor.NETSDK+Samples
I'd recommend vbnet_web_simplepreviewreport
Also, see [this|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a0437ea8-97d2-2b10-2795-c202a76a5e80] article.

When you use @Embed the image is...embedded. That means it is
compiled into
the file, when it's not running. The compiler has _no_ idea
what the value
of your variable is expected to be at runtime.
Try
<mx:Image height="35" width="35"
source="{r.currentItem.mood}"/>

Dynamic image display (based on variable attribute) in Web application?

Hi experts,
I am using a Web Template (from the Web application designer) based on a BEx Query.
This web template displays a logo (jpg image) and the report.
Is there a way to add another image to my web app and having the right logo displayed depending on a characteristic (sales organization for example) chosen in the variable screen (before the first rendering)?
Thanks for your help.
Points will be given to useful answers.
Cheers,
Olivier

Thanks for your helpful answers guys.
Andrey's tutorial helped me to catch the sales org variable value in a variable named salesorg (Script Item in the web template as well as Data Provider Info Item).
Now could you explain how/where to use this variable to swith images? Is this still in the same Script_item where i should be able to "hide" / "show" the following XHTML tag?:
<img etc ....... img<
Thanks for your help, I'm a bit confused on this last point (and not so comfortable with Java Script).

Dynamic Image Display - How?

I have an application which retrieves rows from a database, and also images.
The images are retrieved as JPG files to a specific directory on the WebAS machine, and I have the full path to the file.
I cannot find any way in Web Dynpro to display these images. Is there a way to do it?
Walter

Hello Walter,
i just had that Problem and it was solved in the followuing way:
- Create an HTTP Alias for the directory containing your images
- Set the image-source to http://<host>:<port>/<HTTP-Alias>/<filename>
IWDImage image11 = (IWDImage) view.createElement(IWDImage.class, "Test" + i);
image11.setWidth("80");
image11.setBorder(1);
image11.setAlt("http://netweaver:50000/ZPROT/" + otherImage.substring(offsetfilename));
image11.setSource("http://netweaver:50000/ZPROT/" + aktuellesImage.substring(offsetfilename));
Group2.addChild(image11);
To set an HTTPalias, search the 'Weblogs'

Dynamic image is not being displayed in Adobe Reader 8.1

Hi,
In interactive form, we have followed below required steps to show a dynamic image.
For the left image, drag and drop an Image Field element from the standard Library tab to the Body Pages pane. Select this image field and edit the following properties:
Click on the Layout tab and choose None for the Caption position.
Click on the Object, then the Binding tab and choose None for Default Binding.
Click on the Field tab, enter $record.SapOnlineShopUrl for the URL entry, and select Use Image Size for the Sizing field.
Click on the script editor and enter the following FormCalc script statement, which enables the dynamic integration of the image. Show: initialize Script: this.value.image.href = xfa.resolveNode(this.value.image.href).value;
Language: FormCalc Run At: Client
Image is displayed properly in Adobe reader 7.1 but it's not being displayed in Adobe reader 8.1.
I was going through some forums and understand that Adobe 8.1 blocks href URL. If this is indeed true, what's the alternative way to show a dynamic image?

PlayJpg A = new PlayJpg();
F.add(A);
A.start(); // Web browser calls start() automatically

I only get the first frame picture for ever by my html.But the jpg file is dynamic.
Why?
Can you help me?
Thanks.

Hi,
Add this line inside your run() method, right before your call to repaint():
if (image != null) {image.flush();}Hope this helps,

Not able to display a dynamic image

I'm not able to display a dynamic image on Adobe print form.
Here is what I did.
Please let me know what I need to do to get this working...
1. Created a Graphics node in the Context of the Adobe form.
2. In the URL tab of the graphics node defined the following two lines:
     <URL pointing to the MIME repository folder>
     IM_FILENAME_1
     Where IM_FILENAME_1 is being passed to the Adobeform function module.
3. In the Layout mode, dragged and dropped the Graphics node from the
    contenxt tab to the form layout. On doing so it appears as a image field in the form layout.
4. Activated the form.
BUT, when I run the form , the image is not showing up.
The idea is to pass the image file name to the form so that it will show up a dynamic image at run time.
PLEASE HELP.

Hi Atul,
Try this, that should work.
In the interface , define a parameter type string where you will store the URL of the image .
In the initialization part of the interface , check if the URL is defined, in case it's empty define a default URL . You should put the compelte URL of the image like "http://www.company.org:8080/logo.logo.jpg" .
Then link this parameter to the Grpahic Node in the URL parameters .
Let me know if that works

Any way for one VI to dynamically update images shown in another VI's Image Display control?

I've just discovered (in LV v7.0) that, while I can wire to it, I cannot write image data to a "value" input terminal of a property node associated with an Image Display. When the VI runs I get this error:
"IMAQ Vision: (Hex 0xBFF6051A) The Image Display control does not support writing this property node."
(I must admit that I have to wonder why we are allowed to wire to it, if all it does is generate this error)
Is there any way for one VI to dynamically update images shown in another VI's Image Display control?
I am not interested in using IMAQWindDraw windows.

OK, I have found one way to simultaneously access one VI's image data within another VI without the use of globals. I don't know if it makes use of a known feature of image data that will be with us forever or if it is a bug that will disappear sometime in the future...
It seems that if I create an image data stream in one VI using IMAQ CREATE and name the data stream "ABC" and then create an image data stream in another VI using IMAQ CREATE and also name that data stream "ABC" then in fact they are both the same data streams and they can be read or written by either VI.
Using this feature I can write the common data stream in one VI and using a shared occurrence or semaphore let the other VI know when it is OK to display the data from the common stream.
This method requires that the displaying VI needs to have a while loop around the image display which is not nearly as simple as a display that is updated automagically by another VI writing to a VALUE input that is referenced back to the Image Display. I'd still like to know if there is some way to make that work.
One corollary to this is that if you have several image data streams in use in a system (they can be in totally separate VI's, running independently) and you don't want them tromping on each other's image data then you need to make sure that they (the image data streams) get created with different names. An example of a place where this might bite you (and where I discovered this "feature") is to have multiple copies of the same VI with different names to do image acquisition and display from multiple cameras. Being copies of the same VI, they all had the same image data stream names, defined as constants, within them. When they were run simultaneously, the image data from all of the multiple cameras randomly appeared in all of the image displays. I don't know if this feature would hold up if the separate VI's were turned into separate executables and then run. Do any of you know if this sharing of image data streams with common names works across executables running on the same machine?

Dynamic image in the template builder plug-in does not work

Hi all,
The documentation says:
Direct Insertion
Insert the jpg, gif, or png image directly in your template.
+...This works obviously+
URL Reference
1. Insert a dummy image in your template.
2. In Microsoft Word's Format Picture dialog box select the Web tab. Enter the following syntax in the Alternative text region to reference the image URL:
url:{'http://image location'}
For example, enter: url:{'http://www.oracle.com/images/ora_log.gif'}
+...This works too when I hardcode an url as url:{'http://www.google.com.tr/images/firefox/mobiledownload.png'}+
Element Reference from XML File
1. Insert a dummy image in your template.
2. In Microsoft Word's Format Picture dialog box select the Web tab. Enter the following syntax in the Alternative text region to reference the image URL:
url:{IMAGE_LOCATION}
where IMAGE_LOCATION is an element from your XML file that holds the full URL to the image.
+...This, however, does not work.+
I use Apex' report query tool and My query is like
select 'http://www.google.com.tr/images/firefox/mobiledownload.png' IMAGE_LOCATION from ... (a single result set for my template)
the xml data is generated with an IMAGE_LOCATION tag. I load it to word template plug-in. The Url successfully displays in the report if I make it a plain-simple field.
But when it's in the image format->web->alt text as url:{IMAGE_LOCATION} no image displayed.
I need to keep this design procedure simple so a simple word user could design a report via using just template builder plug-in. I don't wish to explore the xsl-fo area...yet.
Could you tell me why I can't get this url:{IMAGE_LOCATION} to work?
Regards

Dynamic Images in Crystal 8.5

I'm trying to get images displayed dynamically in a Crystal 8.5 report. I have the image data loaded into a recordset and am passing it into the report via a blob field. It is working correctly for a .bmp image file, but when I try to use a .jpg or .png file, the image doesn't show in the report. Is .bmp the only file type supported for Crystal 8.5 or is there something else I need to do to specify to the report what type of image it is?

Hello Jennie,
Iam not remembering about 8.5. I But, Iam sure that itis possible to display image in 8.5 I have done itm, once.
Keep all the image in one folder with unique names which should be the key in database field.
eg:
employee id
I wanto to show the employee image in crystal report.
I will create a formula which will hold the image name.
d:\images\RAB0001.jpg
will be
d:\images\"tempid".jpg
Go to Insert->OLE Object
or
use BLOB object itself
Is this answers your question?

Dynamic Images in Crystal Reports

I have a report with Dynamic Images. I am able to run the report but once I try to export it or try to browse through the pages I get the following error:
Application popup: Crystal Reports - [Inventory Graphics Report.rpt]: crw32.exe - Application Error : The exception Integer division by zero.
(0xc0000094) occurred in the application at location 0x2c03a410.

Hi Don,
I have read your response 10 times, but I don't really understand it.
"Your only option is to use the Insert OLE Object or picture into the report" - fine, but how is this achieved from a dataset?
"CR will not display BLOB fields as pictures" - fine, but maybe I used the word BLOB badly. The dataset column datatype is "byte[]". Will CR display byte[] columns as pictures?
"You can use a database field to point to which picture file to use, then you won't be using up valuable memory space importing the images into your data set. And the Logo's now dynamic...." - this seems to suggest that the database field is a string storing the file location on disk. Yes? I don't care about memory space in this case and I'm happy to load a binary file into a byte[] column if there is a way of displaying it.
So, if I understand correctly, you're suggesting the dataset contain a table.row.column which stores the filelocation. How do I convert that to display as a picture (dynamically)?

Why does moving the mouse over an IMAQ image display slow the GUI down so much?

I have a large application with several vi's running simultaneously under labview 8.6.1. When I mouse over an image display control in one of the vi's, everything slows down a shocking amount in all the other vi's. The windows task manager does not show a large increase in CPU use. My pc is has a quad cpu with 4GB of RAM, and the CPU and memory loads do not appear to be terribly taxing to the system. However, many of my vi's apparently come almost to a standstill if I just move the mouse in a circle around my image control.
This looks like it is largely a GUI display issue. If I make a new vi and put a while loop in it that only displays the iteration loop number to an indicator, I can see the iterating occurring, then stopping totally when I mouse inside the image display control. When I stop moving the mouse inside the control, or when I move it outside the control, the interation loop number jumps up, as if it had been incrementing behind the scenes the whole time. So only display of the interating was halted.
This problem occurs even if the vi with the image control is not executing. If the vi with the image control is open but not running, and I mouse over the image on it, the other guis all come to a screeching halt.
Does mousing in the image display control really utterly crush all other guis in all other labview windows? Is this an issue inherent to the image display control? If so, is there anything I can do about this?
Also, this issue is not entirely limited to display. I started looking at it in greater detail because this issue also exposed what I think is a race condition in my code. I have a vi that acquires an image from a ccd and puts it into an IMAQ image.ctl. This image then gets passed up to a vi up the call chain, and is put on a queue and sent over to be de-queued by a vi that has the image display control. Here's the kicker: when I mouse over the image display control, the image successfully gets acquired inside the subvi, and if I probe the wire leading to the output IMAQ image display.ctl, I see the image. If I simultaneously probe the wire coming out of the subvi one level up the call chain, the image gets lost about half the time. This only happens if I am mousing in the image display control IN A TOTALLY DIFFERENT AND SEPARATE VI. If I bump up the priority of the ccd image acquisition vi to 'highest priority', the problem only happens about 1% of the time, and I really have to mouse around to make it happen. Still, it's disturbing that mousing in the GUI in one window results in a failure of a separate subvi to simply pass an image up the call chain. I understand that IMAQ images are referenced rather than passed by value, but I don't see why there should be a failure to pass the image up the call chain. I've looked for a race condition, but can't find one.

I have finally been able to replicate the behavior that you are seeing on another computer once the image was large enough. Here are a few notes about this behavior:
First. The UI only slows down when the images are large, 16 bit images. The reason why this is unique to 16 bit images is that they can only be displayed on the front panel as 8 bit images. The workaround that Weiyuan suggested to change the 16 bit display mapping hints towards the root of the problem...that any time a mouse runs over the indicator, Windows asks the entire image to re-draw (having a separate indicator overlapping the image will create the same behavior). With a 16 bit image, not only does the image have to re-draw on the screen but the 16 bit pixels need to be mapped to 8 bits. When setting the 16 bit display mapping to Full Dynamic, this requires mor computation/pixel than 90% dynamic or one of the other mapping schemes.
This is expected behavior if your program is running and you're trying to display a large 16 bit image. To fix this behavior there are a couple options:
Change the 16 bit display mapping to something other than full dynamic. You can choose which 8 bits to display or if you want to map the bits.
Resize the image just for viewing purposes on your front panel (since you aren't going to view every single pixel of you image on the screen). You can use the IMAQ Resample.vi to do this. This will allow you to take your 1500x1500 pixel image and only display a 500x500 pixel version.
If you are interested in viewing small details of the large image, consider just displaying a smaller region of interest at a time.
Let me know if any of these solutions work for you. Good luck on your application.
