• How to adapt to the size to display the entire image in the display of the image?

  HI, I use a range of control to display my video images using image display. However, the size is always out of proportion. How can I view the entire image in the size of the screen of box. Essentially, in order to adjust the size for the images?

  You have this option in the indicator of the Image itself. Right-click on the indicator, you will get an option something like "Image Fit with indicator" (sorry I forgot the actual name)

• 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

• use of display and IMAQ image memory

  Hello

  I wonder how much memory is used when updating from imaq image display.

  I need to display images (512 x 512 size) acquired by a camera in real time. But I don't necessarily need show each of them so that can save me some memory. The camera runs at 50 fps and I can live with display rate 5 frames per second.

  Right now my image display is updated from the buffer (updated at 50 fps) continuous (Snapshot mode off). I guess I have 3 options:

  1 use the lifestyle snapshot and say explicitly on the screen to update. Whenever the display is refreshed, a copy of the image is created. But I guess that the previous copy is destroyed at the next update. If this method costs an extra copy of the image in memory.

  2. create an extra copy of the image that is updated only at 5 fps and connect it to the display of the image (Snapshot mode off). I think this is equivalent to method 1, with respect to the use of the memory.

  3. in the State. No additional copies of the image is stored. But the display is updated at 50 fps.

  Which is more expensive, update the display 10 times faster or holding an extra image even copy of the memory size?

  Thank you!

  It is not really a memory problem: you have an indicator to display images. Display an image requires additional resources, but there is no continuous memory allocation! Once the resources are allocated, the use of the memory of your application will remain stable. (Otherwise, something goes wrong and need to be identified and fixed.)

• How can I use a function toolwindow or imaqBCGTransform on the image displayed by the image or the canvas area?

  Hello

  I use LabwindowsCVI8.5 & NI Vision. Recently, I met a problem when I tried to apply a toolwindow on diaplayed of the image by image or canvas block, the toolwindow successfully showed, but could not work. I knew that I can use imaqCreateImage & imaqDisplayImage functions to create the image on a new separate window, then, the two work well toolwindow & imaqBCGTransform, but I just want to know is possible to use the functions of Image processing with image display as part of the UIR or as a subgroup of experts? Coz I think it will be well conventional to see the image processed in this way.

  Thank you very much!

  I've always wondered why there is no control to an IUR for display of an image of Vision of OR...

  Anyway, there is a hack to incorporate a display image of NI Vision window in a Panel. It has already been discussed on this forum but I can't find the link more.

  It goes something like this:

  HWND window_handle, parent_handle;

  int image_window;
  int left, top, width, height;

  initialize the CVIRTE, etc.

  create the parent panel

  Panel = LoadPanel (...);

  get a new handle to display (optional, see the imaqGetWindowHandle documentation)

  imaqGetWindowHandle (& image_window);

  integrate into a parent group

  WINDOW_HANDLE = (HWND) imaqGetSystemWindowHandle (image_window);
  GetPanelAttribute (Panel, ATTR_SYSTEM_WINDOW_HANDLE, (int *) & parent_handle);
  SetWindowLong (window_handle, GWL_STYLE, WS_CHILDWINDOW);
  SetParent (window_handle, parent_handle);
  SetWindowLong (window_handle, GWL_STYLE, WS_CLIPSIBLINGS);

  Position the display where it should be displayed and resize
  imaqSetWindowSize (image_window, width, height);
  imaqMoveWindow (image_window, MakePoint (left, top));

  I hope this helps...

• What software shoud I use to capture an image using my built in webcam in windows 7 ultimate

  * Original title: webcam

  can what software I use to capture an image using my built in webcam in windows 7

  Hi Elizabeth,.

  Normally there will be a software provided by the manufacturer of the laptop computer or the manufacturer of the webcam to take pictures on the computer.

  You can see the laptop manual to check if the computer manufacturer has provided a software for visualization of the webcam on your computer and check if you have the option in the software to capture the image of the webcam on your laptop.

  Also contact the manufacturer of the laptop to learn more on how to take pictures of the webcam.

  For more information, see the links.

  I'm having a problem using the slideshow module in LR 6.3. The slideshow contains the background image as one of the images to display. Earlier, I have created a slideshow of practice and the background image was not displayed as an image in itself. How to make it behave?

  Another approach, perhaps a little more elegant (?). Create a collection that includes images for the slideshow. Include the background image in the collection. Drag the background image in the Panel to designate. Then, remove this image from the collection and create the slide show. I just tried and it works, too.

• I noticed that some jpeg (RGB) images are not display in Internet Explorer 11, but they present very well in other browsers. In addition, the images used to display properly in Internet Explorer. No idea what is happening?

  I noticed that some jpeg images are not display in Internet Explorer 11, but they display well in other browsers. I checked they are RGB images, because apparently some people accidentally use the CMYK format. IE is configured to display the images - I checked that also. The images used to display properly in Internet Explorer, and the images have not been changed on the server. The content was created using Dreamweaver CS6 and Photoshop CS6.

  I tried to view the page on other computers running IE, and they also have this problem.

  Any idea of what could be causing this to happen?

  Thanks for looking in this people!

  I discovered that prevented a few images to display in IE 11, while other images show. The culprit was Adblock Plus for Internet Explorer. Once, I disabled the software Adblock Plus missing images showed once again. Interestingly, I discovered that I could cause the same effect in other browsers using Adblock software. There is either a bug in the software of Adblock, or fluid network of Adobe system, which caused some legitimate images should be blocked. Whatever it is, they do not play well together right now. All images are stored on the same domain, and none of them related off site, so it's pretty weird that they have been blocked...

  Anyway, the mystery is solved! I know people like to see a conclusion to these things as much as possible, so I'll mark this as resolved issue.

• I have Dell ispron B130 running windows xp, how do I print what is displayed on the screen using the PRNT SCRN key?

  I have Dell ispron B130 running windows xp, how do I print what is displayed on the screen using the PRNT SCRN key?

  The 'Print screen' button is misnamed.  In fact, what happens when you press it, it is that an image of the screen is copied to the Clipboard.  You must then open an application that can work with images (paint works) and paste in the opened window (or right-click > paste or edit > paste).  Then you can use the regular print of this application (for example, the file > print).

  You can also download free IrfanView.  It is a very handy utility.  It allows you to open and view a wide variety of image file formats and also has the capability of the bulk renaming of files and - for your current number - capture screen images and prints them out.

• Display of the Image of the attachment?

  Using the sample file (AttachmentTest2_version8_launch_attachment_new.pdf) found here, http://209.46.39.53/thread/341433?decorator=print & displayFullThread = true, I use this to a form which also has an image field when the user clicks to add images to the form and it works fine, but I would like to merge/combine with the functionality of the field where the user selects a photo and image he displayed on the form.  The image field did not have the option to recover the photo when it was submitted, so I'm hoping to find a solution that, once the user adds an image using the image field, this file may be automatically added to the attachment list by the sample file.  In other words, in the sample, the user clicks on 'Add file' select / Add to the list of attached files.  Is - it possible to capture the file and add as an attachment from the field of the image and then still be able to add additional if necessary attachments.  The idea is to be able to display the image of any pic they have.  If there is a better way to accomplish, that would be great and hope that I have explained to ok.  Thank you.

  Extension with Acrobat does not give you this feature... laugh why I said you need LiveCycle Reader Extensions Server to achieve this.

• Acquisition of images using PCI-1426 and Camera Link Camera

  Hello

  I am writing a program to capture images of a Camera Link camera via the PCI 1426 acquisition card in LabVIEW. The problem that I am facing is that I am unable to find the correct controls in the functions palette to start the image capture. Could someone tell me please how much control I'm supposed to use?

  I've worked on similar request sometimes back, I used IEEE 1394 camera, so once I found the correct block diagram controls I should be able to go from there.

  Thanks in advance,

  Sandeep

  Hello Kristen,

  Thanks for the suggestion. I was able to solve this problem. I think that was what was causing the problem I have LabVIEW 8.6 installed on my system and he had the Vision Acquisition System (VAS) 8.5.1. But, once I installed VAS 8.6 I saw the IMAQ in the functions palette.

  I'm guessing that LabVIEW 8.6 does not recognize the toolboxes of previous versions.

• Calculation of frame rates of acquisition image using the 7 Format

  So I finally got my Basler firewire (IEE1394b) camera to capture images at his rate max (120 fps).

  But to do this, I need to use the '7' Format.... which is a bit confusing to me.  When I use the '7' Format, I can't specify the frame (frames per second) rate.  Apparently, you only specify the parameters (length, width, color / mono) of the image and the size of the packets and a few other things.

  So, how can I calculate speed?  I need to know exactly how much time elapses between each image.  And it must be constant.  I can't have a different frame rate.

  NEITHER told I can calculate the frame rate using this equation:

  

  That comes from this article.

  But I am skeptical because the article also says:

  Please note that the time to transfer an image is slightly faster than the time it takes to acquire an image.
  

  People out there can clarify this for me?  Is the frame rate constant?  And then I actually calculate when using size 7?

  The rate will be constant.  It won't change from image to image.  The difficult part is to find what it is.

  Basler camera manual will tell you how to calculate the frame rate.  There are three different calculations, and gives you the slower pace is one you use.  These calculations are accurate enough, I think.

  Another possibility is to measure the frame rate, but that requires several seconds (or minutes) for a measurement precise.  The simplest method is to start a life-long and save a frame in time at the beginning, wait several seconds (or minutes) and save the time of another framework.  Subtract the chassis numbers, subtract the time and divide to get the frame rate.  With a wait of several minutes, it's extremely accurate.  To get the acquisition time, read an image whose value "Next Image", then save the chassis number and read the msec timer immediately after reading.  Using a flat sequence structure is probably the best to ensure that everything happens in the desired order.  If you loop playback, you will see real cadence cadence converge slowly.  Stop it when it is pretty accurate.

  In a program I wrote, I controlled the pace by setting the shutter exposure time.  I used the derived formula of the Basler manual for cadence and reversed to calculate the shutter speed.  This only works if you have another way to adjust the brightness levels (opening, lighting, etc.).

• display of the image of the network

  Hello

  How to load and display an image when it is read from a socket connection? I can only find examples for the loading of the file system.

  I can get the bytes, but I can't find a starting point to display these bytes as a jpeg image using the library of the screen.

  Thank you.

  Try something like:

  char complete_data[image_size];
  bzero(complete_data, image_size);
  int totalBytes = 0;
  while (totalBytes < image_size)
  {
  
      received = read(imagesock, &complete_data[totalBytes], sizeof(complete_data)-totalBytes);
      if(received > 0)
      {
          printf("reading %i \n ", received);
          fflush(stdout);
          totalBytes += received;
      }
  }
