Fastest way to load an image into memory

hi, ive posted before but i was kinda vague and didnt get much of a response so im going into detail this time. im making a java program that is going to contol 2 robots in a soccer competition. ive decided that i want to go all out and use a webcam instead of the usual array of sensors so the first step is to load an image into the memory. (ill work on the webcam once ive got something substanical, lol) since these robots have to be rather small (21cm in diameter) i can only use some pretty crappy processors. the robots are going to be both running gentoo linux on a 600 mhz processor, therefore it is absoleutely vital i have a fast method of loading and analyzing images. i need to be able to both load the image quickly, and more importainly analyze it quickly. ive looked at pixelgrabber which looks good, but ive read several things about javas image handling beging crap. these articles are a few years old, and im therefore wonding if there anything from the JAI that will do this for me. thx in advance.

well i found out why i was having so much trouble
installing JAI. im now back on windows and i cant
stand it, so hopefully the bug will be fixed soon. oIt's not so bad. I mean, that's why we love Java! Once your linux problem is fixed you can just transfer your code there as is.
well. i like the looks of JAI.create() but im not so
sure how to use it. at this stage im tying to load an
image from a file. i no to do this with pixelgrabber
you use getcodebase(), but i dont know how to do it
with JAI.create. any advice is appreciated. thx.Here are some example statements for handling a JAI image. There are other ways, I'm sure, but I've no idea which are faster, sorry. But this is quite fast on my machine.
PlanarImage pi = JAI.create("fileload", imgFilename);
WritableRaster wr = Raster.createWritableRaster(pi.getSampleModel(), null);
int width = pi.getWidth(); // in case you need to loop through the image
int height = pi.getHeight();
wr = pi.copyData(); // copy data from the planar image to the writable one
wr.getPixel(w,h,pixel); // pixel is an int array with three elements.
int red = pixel[0]; // to find out what's the red component
int[] otherPixel = {0,0,0}
wr.setPixel(w,h,otherPixel); // make pixel at location (w,h) black. And here's a link with sample code using JAI. I've tried several of the programs there and they work.

How can I load pattern matching images into memory?

I discovered this problem by accident when our network went down. I could not run my VI because the .png file used for pattern matching was on a network drive. My concern it the amount of time that is required to read a network file. Is there a way to load the file into memory when the VI is opened?

Brian,
Thank you for contacting National Instruments. For most pattern matching programs, the pattern file should only be read from file once and is then copy to a buffer on the local machine. If you examine your code, or an example program for pattern matching, you should see at least two IMAQ Create VI called somewhere near the front of your code. This VI basically creates a memory location and most likely will be called once for your pattern image and once for the image you are searching.
Unless you are specifically calling a File Dialog VI where you are given a dialog box to open a file or have hard coded the file path so that it is read each iteration of your code, then your pattern file should only need to be called at the beginning of your application, th
us causing only one file read over the network for that image. Therefore your program most likely already loads the image in memory once it is read and should not be accessing the network constantly.
Again, I would recommend taking a look at your code to make sure you are not causing a file access every time and then you should be ready to go. Just in case you do have the network go down, I would recommend keeping a copy of the image locally and, if you are feeling ambitious, you can programmatically have your program read the file locally if the network file returns an error.
Good luck with your application and let us know if we can be of any further assistance.

Loading images into memory

I have an applet that I need to load images into memory. For instance, lets say I am in the first section of the applet. While that section is being showed, I want to load the background image of the second section into memory.
To load the initial image into momory, I am just using a Mediatracker. No problem there. But I don't want to load all 20 backgrounds into memory at the same time as they take a lot of time. My understanding is that if I create a new MediaTracker while the first chapter is running, it will potentially cause some chaos, as that will stop my thread from running while I have an image loading.
Somebody told me perhaps I could create a new thread and have that thread load the backgroudn into momory? Perhaps something like this?
public class TestClass extends JApplet {
     private TestClass thisClass;
     public void init() {
          thisClass = this;
          Runnable r = new Runnable() {
               public void run() {
                    MediaTracker tracker = new MediaTracker(thisClass);
                    Image nextImage = getImage( getDocumentBase(), getImagePath() +"img1.jpg");
                    tracker.addImage(nextImage,0);
                    try {
                         tracker.waitForID(0);
                    } catch (InterruptedException ie) {
                         System.out.println(ie.toString());
          Thread t = new Thread(r);
          t.setDaemon(false);
          t.start();
          while(t.isAlive()) {
               int i = 1;
          t.stop();
          t.destroy();
}No idea if I am on the right track or not? Another friend told me something about swing helpers but couldn't tell me much more?
Thanks in advance!

I use media tracker when I need information about how percent the image is loaded. you can use JLabel to load the images since it has own image observer in it.
hope you just want to deal with it. easiest way I can offer :)

I cannot seem to load raw images into LR 2.5. I've been using this for years. I always load from memory card, but it gives me an unknown error message. I tried to load from camera, hard drive, & external drive and still will not work. I checked import menu and nothing has changed. I loaded the photos onto my tablet and images are fine, so do not feel it is the memory card. Any thoughts?

The error message probably said "unsupported or damaged"
The T3 requires Lightroom 3.4.1 or later. You can either upgrade to a more current version of Lightroom (version 5.6 is the most recent) or you can use the free Adobe DNG Converter to convert the RAWs to DNG, which should import into Lightroom properly.

Can I load a vi into memory programmatically

Here's the situation (I'm programming in LV7.1)...
I've got a program that runs, which uses the DSC. I'm wanting to programmatically shut down and quit the Tag Engine when the program ends. My problem is that when I use "Engine Shutdown.vi", all vi's that use the tag engine have to shutdown before the Tag Engine will completely shut down. If I call this an wait (monitoring engine status for shutdown), then I get a deadlock error. If I call this and end the program, then I get a pop up asking if I want to "Stop and close Tag Engine" (and for some reason an error afterwards as well, doesn't describe error, just that a log is being created.) My goal is to have to pop up or dialog boxes appear that the user has to interact with when shutting down.
So the solution that I believe would be appropriate for this would be to close the main program and have a separate vi (that is independant of the main program structure) call the "Engine Shutdown.vi", then quit itself, closing LV. So I've been messing around with this...
"Open VI Reference" with the vi path connected as an input (just a simple vi I made to kill the Tag Engine, wait until it falls, then kills Labview). This is connected to an "Invoke Node" with the 'Run VI' method selected, property 'Wait until done' set to False, and 'Auto Dispose Ref' set to True.
This works all fine on my developement machine, but I imagine I'm going to have issues when compiling this and installing it onto it's target machine. How would I compile this? If I add this vi to the build as a Dynamic VI will it automatically be loaded into memory when the program runs (on the target computer)? If not, is there any way I can programmatically load this vi into memory in such a way where it is not a subvi to my program (else it will have same issues shutting down Tag Engine)?
As always I appreciate everybody's help,
Sean

Mike, thx for your response. Let me run this by you...
So if I put Main.vi and Kill Engine.vi in the same folder on my developement machine, have the attached snippet of code execute when Main.vi is ready to shut down (very last thing to run, after all loops conclude) build the app (with Kill Engine.vi as a Dynamic VI), and install the app on the target machine, does it sound by you that this will work? (Kill Engine.vi is the simple vi I made to shutdown and quit the Tag Engine, wait for this to conclude, then exit Labview).
Thanks,
Sean

Loading an image into an Applet from a JAR file

Hello everyone, hopefully a simple question for someone to help me with!
Im trying to load some images into an applet, currently it uses the JApplet.getImage(url) method just before registering with a media tracker, which works but for the sake of efficiency I would prefer the images all to be contained in the jar file as oppossed to being loaded individually from the server.
Say I have a class in a package eg, 'com.mydomain.myapplet.class.bin' and an images contained in the file structure 'com.mydomain.myapplet.images.img.gif' how do I load it (and waiting for it to be loaded before preceeding?
I've seen lots of info of the web for this but much of it is very old (pre 2000) and im sure things have changed a little since then.
Thanks for any help!

I don't touch applets, so I can't help you there, but here's some Friday Fun: tracking image loading.

Remote Panel: how to load a vi into memory without showing it on the screen

Hi,
I'm using the remote panel facility of LabView 6.1 to allow any user
to control my instruments from within a web browser. However, in order
for this to work, labview has to be running and the vi opened on the
server, which i want to avoid.
Is there a possibilily to enable the labview web server and load a vi
into memory in the background, whithout showing it on the screen?
thanks

> Is there a possibilily to enable the labview web server and load a vi

Not at the moment. The VI truly is running on the server and simply
displaying on the remote machine(s). At the moment it also needs to
have a display on the server. You probably could write a small VI to
periodically look for open LV windows that have connections to them and
minimize them. Then run that VI on the server.

Should I load product info into memory or keep in db?

Hi,
I am going to develop a b2c shopping website with jboss-tomcat bundle. Now I must make a decision on whether I should load product info into memory or just keep it in table. If load into memory, the performance of customer browsing and searching will be good; but I am afraid of the memory capacity and issues like, when I want to update the product price or description, I need to refresh the memory objects. This shop has about 500 products and we will develop this application into Dell server with 1GB memory. Can anyone who has ever developed such e-commerce website give me some suggestions?
Thanks.

I usally use XSLT enabled servlets using Apache Xalan http://xml.apache.org
Its as easy as caching the result of a transformation for a particular URL request in a generic servlet against the string url and putting htem in a HashMap.
Usual architecture is EJN stateless session beans sending xml to a servlet which styles it and caches the result according to configuration.
Work out cache expiry etc later once you get things going.
To answer your question completely, it would be on the servlet side that I would do the caching.
You may be able to do it using servlet chaining or filters, although I have not tried this but have seen some tutorials about this sort of stuff.
The main concept of page caching is storing the whole html page in memory in the servlet (or in a Java class structure contained in the servlet) and whenever a page request matches a cached entry, just send the cached html straight at the browser, instead of expensively creating a new dynamic page.
Consider implementing gzip encoding as well and storing zipped pages in memory, much faster. Avoid implemrnting stuff that a proxy server would give you out of the box.
I usually try to configure what urls are cached and what are not.
If you are using JSP, I am sure someone has implemented caching of jsp content, a preoduct called Tiles perhaps?

How to load an image into blob in a custom form

Hi all!
is there some docs or how to, load am image into a database blob in a custom apps form.
The general idea is that the user has to browse the local machine find the image, and load the image in a database blob and also in the custom form and then finally saving the image as blob.
Thanks in advance

Unable to load TIF images into Photoshop.

CS4 (11.0.2) and Windows 7 Home Edition.
Have developed a problem trying to load some TIF images into Photoshop. I have a large number of images archived over a decade or more. At this point it may some of the older files that exhibit the problem. Now all these files were edited and stored using the Photoshop versions during the complete time period. The files are always saved with no compression. Have tried to load from Photoshop and clicking on the file in a file list. Photoshop just hangs and I get the message Program not responding. I can take these same files and load them into the ROXIO photo editor with no problem. Stranger yet is if I simply load the file into the ROXIO editor then "save as" back into the same folder (overwrite) the file can then be brought into Photoshop with no problem! Any ideas?

Noel,
Will try to keep short.
I reinstalled Photoshop CS4 from the cd CS set. Did not uninstall first. Restarted PC and Photoshop. Still failed the same way with a 3001 image.
Did the following, changing one item in the Edit->Preference->GPU Setting. After each change, closed Photoshop, reopened, brought in 3001 image, restored original setting. 3001 failed each time.
* Unchecked Enable OpenGL Drawing
* Advanced setup: Unchecked Advanced Drawing.
* Advanced setup: Unchecked Color Matching
Next went to the Edit->Color Profile.
Scanned thru options and saw in the Convert Options: Engine. It was set to Adobe (ACE). ACE was the module name in the error detail!
Only other option for this is Microsoft ICM. Changed to that, close/open Photoshop and 3001 came in no problem. So did the Nikon 3000, srgb IEC 61922 2.1 and Untagged. However, when briging in an Adobe RGB(1998) image Photoshop notes Profile Mismatch. It allows me to decide what to do (use embedded profile instead of workspace; convert color to work space color; discard embedded profile. and I choose use the convert color and it loads ok. At least it loads the image! Will use this approach for now. I need to get educated on color profiles!!

How to dynamically load an Image into a TableView when its row/cell becomes visible?

Hi,
I am building an application that shows tables with large amounts of data containing columns that should display a thumbnail. However, this thumbnail is supposed to be loaded in the background lazily, when a row becomes visible because it is computationally too expensive to to this when the model data is loaded and typically not necessary to retrieve the thumbnail for all data that is in the table.
I have done the exact same thing in the past in a Swing application by doing this:
Whenever the model has changed or the vertical scrollbar has moved:
- Render a placeholder image in the custom cell renderer for this JTable if no image is available in the model object representing the corresponding row
- Compute the visible rows by using getVisibleRect and rowAtPoint methods in JTable
- Start a background thread that retrieves the image for the given rows and sets the resulting BufferedImage in a custom Model Object that was used in the TableModel (if not already there because of an earlier run)
- Fire a corresponding model change event in the EDT whenever an image has been retrieved in the background thread so the row is rendered again
Btw. the field in the model class holding the BufferedImage was a weak reference in this case so the memory can be reclaimed as needed by the application.
What is the best way to achieve this behaviour using a JFX TableView? I have so far failed to find anything in the API to retrieve the visible items/rows. Is there a completely different approach available/required that uses the Cell API? I fail to see it so far.
Thanks in advance for any hints here.

Here’s what I have tried so far:
I have defined a property in my model object that contains a weak reference to the image that is expensive to load. I have modeled that reference as an inner class to the object so I have a reference to its enclosing object. That is necessary because my cell factory otherwise has no access to the enclosing model object, which it needs to trigger loading the image in the background.
The remaining problems I have is, that I don’t have sufficient control over the loading process, i.e. I need to delay the loading process until scrolling has stopped and abort it as soon as the user starts scrolling again and the visible content changes. Imagine that loading an image for a table row (e.g. a thumbnail for a video) takes 200ms to load and a user quickly scrolls through a few hundred records and then stops. With my current set-up, the user has to wait for all loading processes that were triggered in the cell factories to finish until the thumbnails of the records they are looking at will appear (imagine an application like finder to be implemented like that, it would simply suck UX-wise). In my swing application a background thread that loads images for the visible records is triggered with a delay and stopped as soon as the visible content changes. This works well enough for a good user experience. I don’t see how I can do this based on the cell API. It is nice to have all this abstracted away but in this case I do not see how I can achieve the same user experience as in my swing application.
I also tried registering a change listener to the TreeCell’s visible property to make that control the image loading but I don’t seem to get any change events at all when I do that.
I must be missing something.

Is there a way to drop an image into indesign and then have that file name captioned underneath?

Hello! I'm looking to help a colleague into streamlining a process. We have to display images full page in an Indesign Document and every time we drop and image onto a page, we then need to edit the caption underneath with the file name. Just wondering if there is a way to automate this process? Any scripts available?

When you place an image you can turn on the capture function. There are normal and live versions. The normal labeling creates a text as text is, the live version creates a variable which would change if the image or the text in the meta information changes, but it behaves like a single character which causes problems how the text will run in the text frame.
What is drawn out of the Meta must be set up before in the caption set up option.
When you drag and drop an image from the finder or from Bridge you can't activate this option.
BTW I use it a different way which seems to me faster. I assign a shortcut to the labeling command and when I have imported the image, I click this shortcut and in a second step I apply an Object style which will format the text frame including Paragraph style which might be different on a dark or bright photo or upon a graphic.
Normally I edit all meta information in Adobe Bridge, which is the fastest way to handle it.

Is there any way to load idml file into InDesign server Programmatically

Making a loaded external image into a button in Actionscript

My name is Steve Oatman I am a student at
AIO for a Web Design Diploma
class: Interactive Telecommunications IMD412 XA
Professors to bussy!
I have a flash web site that I am putting together. I am using AS to load some images from an external source. These images are being loaded into a movieclip. These images need to become buttons once they are loaded. The images will link to the particular menu category pages beef, chicken, etc.
The images are loading fine they just are not responding like a button or link.
I am getting two error referencing the buttonMode and usehandCursor. Below is just one image that I am working on till I get it to work.
I am getting these two Compiler error code:
1119: Access of possibly undefined property buttonMode through a reference with static type flash.display:Loader.
1119: Access of possibly undefined property useHandCursor through a reference with static type flash.display:Loader.
This is what I have.
var myLoader01:Loader = new Loader();
myLoader01.load(new URLRequest("entrees_images/beef/beef01.gif"));
addChild(myLoader01);
myLoader01.x = -269;
myLoader01.y = -164;
myLoader01.buttonMode = true;
myLoader01.useHandCursor = true;
myLoader01.addEventListener(MouseEvent.CLICK, beefClick);
function beefClick(event:MouseEvent):void{
gotoAndStop("beef");
From me searching online I thought the
name.buttonMode = true;
turned the element into a button!
I have included the fla file. This is in the menuItems_mc which is located in the pageContent_mc frame 40 layer page Image or of course the library.
I know this is a little in depth sorry and any help would be greatly appreciated.

function addIt(evt:Event):void{

   aBtn.x = -269;
   aBtn.y = -164;
   aBtn.buttonMode = true;
   addChild(aBtn);
   aBtn.addChild(myLoader01);
   aBtn.addEventListener(MouseEvent.CLICK, beefClick);
myLoader01.contentLoaderInfo.addEventListener(Event.COMPLETE, addIt);
myLoader01.load(new URLRequest("entrees_images/beef/beef01.gif"));
