• sequential reading of the image and plot greyscale

  Hi all

  I have attached a VI wrote in LV version 8.2. All I am trying to make bed image sequence from a specified location in the PC and get the value in pixels for those of all of the images and want to save it in a file. When I run the vi it says error - 1074395995 IMAQ read file not found.

  Any help would be appreciated.

  Hi Theresa,

  As Andrey says put the extension on the end and it works. for example, change:

  'C:\Documents and Settings\Administrator\Desktop\Modulation speckle depth for Malinowski to low frequency\2Hz2.8Vpk-pkRHOE\2Hz20001' to

  "C:\Documents and Settings\Administrator\Desktop\Modulation depth of speckle to Malinowski to low frequency\2Hz2.8Vpk-pkRHOE\2Hz20001.jpg.

  or any file format are your photos.

  Thank you

• How read/view the image from SD card on the device

  Can someone please pass on a link that has a tutorial for the playback picture from sd card on the BB device. Thank you.

  Read the file into a byte array (let's call it data) using FileConnection (is there an example in the docs, enough to get you started), then call EncodedImage.createEncodedImage (data, 0, data.length) to create an EncodedImage.

  From there, you can do with this image you want - BitmapField.setImage (), graphics.drawImage (), etc.

• I'm retouching of images taken on my iPhone 6 more with Photoshop CS6. I'm doing my color correction and add effects and all that. Before you export the image I review and be sure to what I has no more sharpness and the lines are smooth and it looks good

  I'm retouching of images taken on my iPhone 6 more with Photoshop CS6. I'm doing my color correction and add effects and all that. Before you export the image I review and be sure to what I has no more sharpness and the lines are smooth and it looks good overall. I export it to JPEG, max quality with the establishment of reference standards. I then open the image and it seems fine, as it did in photoshop. My problems begin to occur when I try to download on Twitter as my profile picture. I tried downloading from my office directly on the site via google chrome. When I download the image then begins to have jagged edges and overlooks the tablets. So I thought it was some performance settings, then I tweaked them and restarted a couple of times and still the same result. He would go on my desk but when uploaded to twitter as my profile picture is horrible. So I tried emailing the image of myself and the download through my phone. I opened the image on my iphone and it seemed fine as he did on my desktop but when I downloaded the image it makes then look blurry. I had this problem when downloading photos Twitter via my iphone, so it doesn't surprise me. I have read different forums saying: you must download it from the office, so I thought it would work like this. This could be a problem of twitter than compresses uploaded photos? Other people can do very much the same way, but it does not work for me. Please someone help me before I put my computer in an oven microwave.

  This could be a problem of twitter than compresses uploaded photos?

  Yes. The rest, we can answer. You wrote a lot, but very little discussion. Instead of accurate information you lose yourself in the vague descriptions. Screw color management to the wrong dimensions that trigger resizing server-side it could be any number of things here.

• What is the most effective way to bring up the 1 of 4 images at any time?

  Thanks for reading this.  I have the same exact image need to attend different places in my program.  Right now, I created a movieclip with the image and I pasted in my step 4 different times and given to each instance a different instance name.  I would make a more effective program if I changed the location in the script of the video and has said the Stop program on a different image for each image, I need?

  What I'm trying to do, is to have a user to select from 4 different options and if they choose option 1, for example, the image of LED for option 1 light up and the other 3 lights will be off.  So, right now, if they choose option 1 I put ownership .visible to false for the other 3 images.  Is there a better way?

  The visible property control is very good.  If there is no need to show three of four, and they are identical in all cases, it may be better to simply have an and control its position.

• The most effective way to log data and read simultaneously (DAQmx, PDM) high data rates

  Hello
   
  I want to acquire the data of several Modules cDAQ using several chassis to
  high data rates (100 k samples per second if possible). Let's say the measurement time is 10 minutes and we got a large number of channels (40 for example). The measured data is written to a PDM file. I guess, the memory or the HARD disk speed is the limits. For the user, there must be a possibility to view the selection of channels in a graph during the measurement.

  My question: what is the best and most effective way to save and read data at the same time?

  First of all, I use an architecture of producer-consumer and I don't want to write and display the data in the same loop. I expect two possibilities:

  [1] to use the 'DAQmx configure logging.vi' with the operation 'journal and read' to write the data to a PDM file. To display the data in a second loop, I would create a DVR samples documented and 'sent' the DVR for the second loop, where the data will be displayed in a graph (data value reference). This method has the disadvantage that the data of all channels is copied into memory. Correct me if I'm wrong.

  [2] use 'DAQmx configure logging.vi', but only with the "journal" operation to write the data to a PDM file. To view the selected data, I had read a number of samples of the TDMS file in the second loop (I'm currently writing the TDMS file). In this case, I have only one copy data from the selected channels (not), but there will be more HARD drive accesses necessary.

  What is the most effective and efficient solution in this case?

  Are there ways to connect and read data with high frequencies of sampling?

  Thank you for your help.

  You say that the measurement time is 10 minutes. If you have 40 channels and you enjoy all CHs at 100 kHz, it is quite a number of values.

  In this case, I always try to approach under the conditions of use. If a measure is only 10 minutes, I just connect all PDM data and create a graphic module that could be in the same loop of consumers where connect you the data. You can always work on the raw data files big offline afterwards, the extraction of all the information you need (have a look at the product called NI DIAdem: http://www.ni.com/diadem/)

  The main issue is that the user needs to see in the graph (or perhaps a chart can be useful too). Lets say that the graph is 1024 pixels wide. It makes no sense to show multiple data to 1024 points, Yes? Every second will produce you 100 data points k per channel. What is the useful information, which should see your username? It depends on the application. In similar cases, I usually use some kind of data reduction method: I use a moving average (Point by point Mean.VI for example) with a size of the interval of 100. This way you get 100 data points of 1000 per channel every second. If you feed your graph every second with these average values, it will be able to data points in 1024 of the store (as a default) by channel (curve), which is a little more than 10 minutes, so that the user will see the entire measurement.

  So it depends on the frequency at which you send data to the consumer. For example, collect you values 1024 by iteration of the producer and send it to the consumer. Here you can make a normal means calc or a bearing (according to your needs) and he draw a graphic. This way your chart will display only the values of the last 10 seconds...

  Once I programmed some kind of module where I use a chart and not a graph, and the user can specify the interval of the absolute timestamp that is traced. If the data size is larger than the size of the chart in pixels, the module performs an average calculation in order to reduce the number of data points. Of course, if you need to see the raw data, you can specify an interval that is small. It all depends on how you program zoom functions, etc... In my case I hade a rate of 1 Hz, so I just kept all data in RAM limiting the berries to keep 24 hours of data, so that technicians could monitor the system. In your case, given the enormous amount of data, only a file read/write approach can work, if you really need access to all of the RAW data on the fly. But I hope that the values of working capital means will be enough?

• On the EOS 7 d Mark II is the supposed main dial to enlarge the image of reading?

  I want to check the sharpness that I pull on my EOS 7 d Mark ii. I know how to read the image. I can't click on the index/reduce/enlarge button to zoom. But I've also read where the main dial to zoom in even closer. Am I wrong? If so, my camera won't do. When I turn the main dial in play mode, it only contributes to the following image. Help please!

  On the 7Dd2, you press on the magnifying glass to zoom in, and then use the wheel near the shutter button to zoom more.

• How to make text does not interfere with the rollover effects in the image below

  I have images that zoom slightly when the mouse passes over them, but I need a title text on them. When the mouse is over the text, it prevents the zoom effect doesn't happen. Is there anyway to make the "invisible" to the cursor text and does not interfere with the effects of overview below? I know that I can make the text in the images, but I don't want the text to expand it, just the image.

  You can use a button on the State.

  

• Replace the image in a model created in After Effects

  I created a model intro to After Effects that has little text and the animation of a masked image. If I import this model ASP in Premiere Pro, I can easily replace the text, but I can't find a way to replace the image too.

  Is this possible? How?

  If I understand what you're asking, yes it is possible. I place the image in a sequence, use the corners effect to adjust the shape of the frame, remove in the middle of the image, place the image behind and used the corners on the photo to match the frame.

• Lose the layer effects when I flatten image Photoshop CC

  How can I keep my layer effects when I flatten an image or the merger of the layers?  I tried a few ways to merge: for example merge down to an empty layer, visible merger, stamping the image, the rasterization of the layers, saving in jpg format, but still lose the effect.  I can also send it to a lab to be printed with all layers intact, as it is more than 1 GB in size. I searched the net for an answer, but all suggested does not work.  Help, please.  I really need to solve this problem.  Thank you

  It seems to me that you apply tonal corrections of black and white line art, or an image with the frame of halftone (points) (or something similar).

  That won't do anything because all you have is still pure black white and pure - but it will look as it does If you look at what it is other than 100%.

  
  

  The reason why the adjustment seems to take, is that you look at a preview resampled, cached, and resampling softens the edges and introduced middle gray values.

  When you group, the adjustment is calculated on the original size. Then he "disappears", because it is actually nothing to resolve.

  I could be wrong and it's something else - but is a very common question and a good bet.

  CC have reinstalled due to the failure of the system.  When opened in the image space RAW goes yellow spot, with blue background.  I reinstalled without effect.  At the opening, in RAW, the image is restored for future treatment.  Error occurs with both dng and arw.  Ideas.

  Try the following:

  In the Camera Raw window, press Ctrl + K (Cmd + K on a Mac) to bring up the preferences.

  Uncheck the box processor graphics use.

  If that suits him, update your graphics driver may allow you to work with the checked graphics processor.

• Urgent! Help, please. I want to create an effect of deformation that changes little by little through the image

  Hello. I have a model that consists of a large number of small irregular dots in a diagonal pattern that I have repeated it. I need to make some sort of Warp effect so that the points at the top of the image are crushed together making them more "dense" and low points are tight and more spaced making it "less dense". This effect must be gradually from top to bottom. Essentially points to the environment will be like in the original, in the upper part that they will be crushed and down spread.

  I'm new to Illustrator and have tried envelope distort, but can't seem to find an effect that will give me the progressive change. Can someone help me please?

  5.1 Lightroom ceased to import JPEGs of iPhone. The iphone and the images will be displayed, but import said that they cannot be read. This has just begun. Even the phone, IOS and the OS.

  The message 'could not be read' indicates you do not have WRITE permission on the destination folder. So, here's what you need to do

  1. The Lightroom Import dialog box, go to the Destination section to the right and make a note of the specified folder.
  2. Change the folder to something else; OR in your operating system, change the permissions on this specific file WRITE permission.

• Is there a way to apply the shadow to a masked image effect?

  Is there a way to apply the shadow to a masked image effect? (Hidden through the default effect video opacity). When I try to do, the shadow effect applies to any image not only the hidden portion.

  I have not messed with the masks very well, but you're right. The shadow does not work on a masked image.

  I got it to work if by nesting the masked image.
