Gallery of images using Javafx

I have a folder that is full of pictures. I am trying to build a desktop application that can perform the following tasks.

1. Select the folder and view images as thumbnails, as we see in the picasa/all image viewer.

2. the image should be clickable and can be opened in full screen using the application.

3. several image choices must be possible.

Now, I'm stuck at the first requirment, where I'm not able to identify how to show the files that I've analyzed the file as thumbnails and stack together to show part of my application.

I know that I don't have any piece of code, I just wanted a logic whereby I can develop it. One idea is welcome.

Kind regards

Aerts

I use ImageViews instead of a button and register the listeners of the mouse to manage the selection.

You want to make decisions about how you handle issues of memory, as Jorn said. You can load to the top of the resized images miniature versions and then reload the version full image to view it in full screen, or you can load the full versions of all the images and just resize the views of these miniatures. The first method preserves the overall memory and might display a little faster (not sure about this) thumbnails, but there would be a little late to see the full version of the images. The second method uses more memory overall, but show the full version would be very fast. The second method would also provide mechanisms for the user to resize the image, if it was something you want.

I would use a FlowPane or a TilePane to display the collection of miniatures. See , working with presentations in JavaFX: available built-in shutters | JavaFX tutorials and documents 2 for a description of these.

Then you can do

// ...

Pane imageContainer ; // initialize to TilePane or FlowPane as desired
List imageFiles = ... // get the list of image files
for (File file : imageFiles) {
     ImageView imageView = createImageView(file);
     imageContainer.getChildren().add(imageView);
}

The first method (resizing of images loading):

private ImageView createImageView(final File imageFile) {
     // DEFAULT_THUMBNAIL_WIDTH is a constant you need to define
     // The last two arguments are: preserveRatio, and use smooth (slower) resizing
     final Image image = new Image(new FileInputStream(imageFile), DEFAULT_THUMBNAIL_WIDTH, 0, true, true) ;
     final ImageView imageView = new ImageView(image);
     return imageView ;
}

To load the full image and resize only the view, use this version:

private ImageView createImageView(final File imageFile) {
     final Image image = new Image(new FileInputStream(imageFile)) ;
     final ImageView imageView = new ImageView(image);
     imageView.setFitWidth(DEFAULT_THUMBNAIL_WIDTH);
     imageView.setPreserveRatio(true);
     imageView.setSmooth(true);
     return imageView ;
}

For the selection, I would create an ObservableSet of selected images. Depending on how you view the full version, you may need to store file objects in this set, or it may be sufficient to store the Image objects in there. So, something like:

Final ObservableSetselectedImages = FXCollections.observableSet ();

In your createImageView method (or a method that you call from there), you can save the mouse with the ImageView listeners; When the mouse is clicked simple, either replace everything in the game with the current image, or (for example, if the shortcut key is pressed) add the current image to the set. It could also save a manager of mouse double click here to view the full image.

Always in the createImageView method, I would register a setChangeListener with all images selected, which ensures that the display of the image has a style of "selected" class when it is overall and has not this category if it's not in the game. Then use one stylesheet external (say) draw a border around the image display when selected.

It is easy to do this for the pictures shown in the page view IR. It would be much more complicated to do this for all of the images returned by the IR motion, including those not visible on the current page.

1 create a column of thumbnail image in the IR using the support integrated BLOB. If necessary and style thumbnails by using a style sheet in the header HTML page:
2. create a dynamic Action to bind calls Fancybox for thumbnail when IR is updated.

When

Event: After refresh
Selection type: Region
Region: IR Gallery / / whatever your area

Real Actions

Action: Run the JavaScript Code
Fire on Page load: Yes
```
/*
  Wrap each thumbnail image in the link element required by Fancybox.

  The rel attribute enables the Fancybox gallery feature.

  (jQuery is used for this because it appears APEX does not provide a good way of making the BLOB
  into a link that references its source.)
*/
$('#employees td[headers="PHOTO"] img').wrap(function() {
  return '';
});
/*
  Bind the required Fancybox call to the thumbnail links.
*/
$('#employees td[headers="PHOTO"] a').fancybox({
  'type'          : 'image',
  'transitionIn'  : 'elastic',
  'transitionOut' : 'elastic',
  'speedIn'       : 300,
  'speedOut'      : 300
});
```
3. change the Fancybox options used for the required appearance and behavior.

Cannot find the Gallery of images for screen saver in Windows Xp

Original title: Gallery photograpique for screen savers

I can't find the Gallery of images used in my screensaver in old computer to copy to the new computer. Windows XP Home Edition is my op system.

Hello

Start/Search/*.jpg should be able to locate the folder, though it may take a little. Or, check the settings for the screen saver on the old machine to see which directory is used.

====================================
Sometimes the only resizing is not the answer because the
the original size is different from the print size.

You may need to crop photos to the size you want
print to ensure that no clipping will occur. Cropping
to a different aspect ratio will lose some parts of the picture but
at least you have control over it.

Windows Live Photo Gallery is a cropping tool.

CORRUPT IMAGES USING VISTA HOME PREMIUM

Why is corruption of J ankles always a problem in windows 7? and the custom of whay Microsoft recognize that there is a problem?
I've read about it all over the internet and had it happen to me. If you want to reproduce the problem, use a pc using windows vista (and I don't think it matters which version you are using) an AMD processor and an invidia video card.

Hi fitter562,

Please provide the following information, in order to better understand the issue:

(a) what exactly happens when you view photos? How do you know that the pictures are corrupt?

(b) what software or applications do you use to see all the photos?

Try to display the same image using Microsoft Paint and Microsoft Windows Picture and Fax Viewer, you encounter the same problem?

Note: Microsoft Paint and Microsoft Windows Picture and Fax Viewer do not color profiles to manage the parameters of color for the images.

When you view an image in the photo gallery Windows on a Windows Vista-based computer, the image and the background of the image are yellow.

This problem can occur because an incorrect color profile is used for the monitor in the color management device. When the Windows Photo Gallery uses the incorrect color profile to manage the parameters of color for the images, you experience the problem this question.

When you view an image in the photo gallery Windows on a Windows Vista-based computer, the image is yellow

Hi Buckyball1982,

What version of Android phone do you use?

You have a built-in file Explorer or any Explorer third-party file installed on your phone?

If not, then I recommend you to install an Explorer of files on your phone and you would be able to browse the files in the Acrobat DC application on your Android phone.

Kind regards

Gallery of images with scrolling thumbnails?

Hi all
I am trying to build an image gallery containing 1 Overview as well as a strip of thumbnails Horizental allowing hollows of scrolling thumbnails
can someone explain or highlight a good tutorial for that?
Thank you
ADI

Hello Adi,

Ah I see! Please take a look at the source code of this Web site. You will find that this gallery is created using "javascripts/hislide. According to the author, this "Highslide JS is a viewer of image and Media Gallery written in JavaScript". You can get more information about this software here: http://highslide.com/.

Apart from that, I think, there is no significant difference - especially with my last two.

Gallery of images with CSS menu
I have a gallery of images (slideshow) created with Flash and XML. My site uses a drop down css/javasript for navigation. The drop-down menu behind the slide show little matter what I set the z-index for. Y at - it something in flash that allows me to set its z-index? I could drop the menu on the page and give a link back, but it is a workaround and I would rather stay consistent with my site. Any assistance that could be given would be appreciated.

Mark V.
Just to inform anyone interested, I found the answer on another forum. Here is what has been given to me:
If you paste your swf nto normal web with HTML, add the following setting

and also the attribute wmode to the embed tag

Otherwise, if you use the SWFOBJECT method to add this line after the "var so ="line ".
so.addParam ("wmode", "opaque");

I added the settings listed above and then added the attribute wmode = opaque in the embed command and it works fine.

Vectorize an image using Labview

Hello world!

So, I work with a 3D cutting machine (Roland MDX - 15) and I'm supposed to design a program that can load images and burn them on a piece of wood using Roland MDX - 15.

What I've done, is to create a program where you can draw a picture using the tools of sketch of Labview and the machine will sculpt.

The machine is capable of carving the image using vectors (she follows lines point by point).

Now, I have to do the same thing, but an image that I have load in Labview. Therefore, I need to vectorize the image so that the machine gets a set of lines to draw. A program that is already it is Dr.Engrave (see youtube if you need to understand what I need).

So, anybody know a 'simple' way to transform an image into a set of vectors?

Thanks in advance!

Hello VGans,

I assumed that when you talk of tracing any edge detection method would be allowed to help you get started.

If it is a false assumption, then let me know.

Keeping this in mind:

Already taken a peek at the "IMAQ CannyEdgeDetection' VI?

This could be a good starting point for tracing purposes.

Can you let me know if that's what you're looking for?

some computers cannot acquire images using the PCI-1410

I have a big problem in the acquisition of the images using the PCI-1410.

It was a standard camera (SONY XC-ES). The test of the device is OK with my computer.

I can not get a correct image via MAX. Also, I try to use the file of the camera for that camera.

But it did not work properly.

I consulted it toward the Korea of NEITHER and they discover THAT PCI-1410 worked properly with different computers.

So, I try to change PC. Most of my computers cannot acquire the image even if the unit is OK of MAX.

However, only a few computer works properly. (Work computers are from SAMSUNG. The other

computers that did not work propely, were assembled in the lab.) (I have tested almost 6 computers for this purpose.)

The problem is that there are at least 3-4 PCI ports for our applications. The work computer (SAMSUN) only has 2 ports PCI.

What should I do to select the right computers? I can't buy dozens of computers to test the PCI-1410.

Why is this kind of problem occurs?

Thanks in advance for your advice. (Email: [email protected])

Hello

We also had a lot of problems in the past with different PCs and the problem came from the motherboard. Since that time, we only use motherboards with intel because we know that labview works very well with them.

It was 2 or 3 years ago, and I thought that the problem has been resolved since then... you know the type of motherboards you use?

The question is more how you want that they be indexed like that?

1 > 2 > 3 >... > 15 > 16 > 1 > 2...

5>6>......

or

1 > 2 > 3 > 4 > 5

Continuous imaging using vision builder

Hello, I use NI 1744 and want to know how to get and record continuous images using Vision Builder. I am in a position to acquire and maintain a single image but cannot acquire continuous images.
Looking forward for your help.

Bürki,

You try to save the images continuously as a movie? This is not supported in VBAI, however if you want to align continuous images individually you can try to change your pattern of State inspection to repeat your current inspection and the transition to the stage stop only after that your current inspection was conducted a defined number of times.

Which is faster a bit manipulation to the table or image using the vision

I have to perform an operation on an image. It involves the calculation of the new locations for the pixels for each pixel of the image. Which is the fastest way to do it. Manipulate the pixels as elements of the array for loops, or manipulate the pixels of an image using vision tools?

Thank you.

Hello

If you can use vision tools to make the manipulation of pixels, it is much faster.
