• Draw freehand on the container to Image Vision - are part of the Image

  Hello people.

  You want to do a random draw on the fly on a 8-bit grayscale image into a container of Vision.  I then want to merge this draw with the actual image.  I suppose that the draw is an overlay.  Vision has a superposition of merge command that requires RGB destination.  I then used the IMAQ extracted SingleColorPlane to extract the plan of the intensity of the RGB image so that I can return to the plan format unique (U8) use IMAQ ImagetoArray fx to get to a table.  I tried to extract a number of different types of aircraft, but do not see my line on the resulting table (which I display in a graph of intensity).  I don't see the original image.

  Any thoughts on the best way to accomplish a merger of the draw and the original image?

  Thank you

  I write an example showing my current best effort quick a solution non-Vision, not covered with this problem. This approach was mentioned in my previous post.  I will cross-post this in the forum LabVIEW also since it is a solution of pure-LabVIEW.  It is difficult for me to believe that we can not directly to these "overlay" information using NI Vision NI LabVIEW.

  After the line drawn for all positions of the cursor (cursor) feather flying over the interpolation is required. I used the factor 10 and spline interpolation.

  Drawing of the points on the graph of the intensity, rather than lines, did not work well, because with my code, I'm clearing missing events related to seize all slider positions.

  Feel free to let me know if you can do better.

  Sincerely,

• How to reduce the memory usage when loading bitmaps from the library?

  When I use BitmapData.loadBitmap () to load an image in the library, then attachBitmap() to add it to a MovieClip it takes a lot more memory instead of just to have the same image inside a MovieClip statically in a frame in the timeline.

  The dispose() function not only deletes the BitmapData object but also destroys the bitmap previously attached inside the MovieClip, so it cannot be used to free the memory.

  Is - this how it is supposed to be or there at - it another way to dynamically attach bitmaps with comparable rightly memory use have them on stage?

  You can do the same thing with movieclips: create a bitmapdata instance and use the draw() method to overlay as needed.

• playback of youtube videos using video Overlay option in indesign

  Hi, (I'm starting a new thread on this video issue since its different from the issue of audio playback)

  My original question was; video links youtube work with the video Overlay option in Indesign? I tried a handful of ways and I only see a video player when I export the .article and the view on the ipad. I've attached screenshots. The last of them agrees ipad.

  Thank you!

  For streaming of YouTube videos, the best approach is to create an overlay of Web, not a video overlay.

  1. choose the command object > insert HTML code and paste the embed code you copied from YouTube. When you click OK, a decorative frame of web is created in the right dimensions. It usually has a horrible black frame with a Flash warning. Which ignores for now.

  2 Select the web object and select Auto Play in the overlays Panel. This car plays the web object, not the video itself.

  3. Add a static image poster with a button "play" on the web overlay.

  Let us know if you have any questions.

• Play HTML5 video with JavaScript does not hide the overlay dimming video

  I googled this problem and found nothing useful and also checked the area of support here and still nothing. I'm creating a webpage with HTML5 video. I made a layer with the video object that is hidden with CSS, until the user clicks on a link. When the user clicks on the link, I use a JavaScript function to display and play the HTML5 video object. Works fine except that Firefox keeps the overlay in place play button while playing my video! If I click on the overlay, the video stops. Then if I click again, the overlay disappears and the video resumes playback.

  I realize there are solutions that can be pirated. But it is certainly a bug that the rest overlay in place after the start of the video via a JavaScript command. I hope that this problem finds its way to the right people at Mozilla for resolution.

  Thank you

  Can you please update to Firefox 18.0.1 and see if the problem exists in a new profile? (13 is no longer supported)

  Use the Profile Manager to create and delete profiles Firefox

• Satellite L305-S5921 - video playback is fuzzy, not clear

  I hope this isn't a double wire - I have done several searches, but couldn't find it, so forgive me if I missed it.

  In any case, I bought the L305-S5921 a couple of months. It's a great phone for the price. My only complaint is video playback - it is not at all crispy and is rather blurry. When I watch DVDs and watch videos of resolution "superiors" on Hulu, it's blurry (Note: 'High resolution' Hulu is 480 p).

  I tried to adjust the resolution of the laptop before video playback, but it doesn't seem to help.

  I read a review of this laptop on the review of a store page, and he said he had to change video playback. Someone has any idea how to "fix" it? I couldn't email this person, as it was anonymous.

  Or, do you know if any programs (like ffdshow) will help? I think this can help with the DVD, but does anyone know if it would help with streaming from Hulu?

  If you can help, please be as explicit as possible - I have some technical knowledge, but this problem seems to be beyond my comprehension!

  PS - everything on this laptop looks great - photos, games I play (not too demanding of salvation graphics, etc...). It's weird because I've had this laptop to replace your old desktop (7 or 8 years old) that I had (with a CRT monitor). But, this monitor seemed better on video than this laptop brand new with a resolution of more than world!

  Thanks in advance!

  Hello

  Especially videos that are broadcast from different pages are saved or transformed in low resolution.
  Why?
  Due to the transfer of data high.
  Movie files high resolution are too large to download common or upload.

  So if you scale movies in full screen, then it might be possible that the resolution of the film would not be perfect.

  But this isn't a number of laptop but it s files of movies that are broadcast from different pages like youtube or hulu

• Highlight the option IMAQ Oval overlay

  Hello fellow programmers.

  I was wondering if someone could explain the following: why are there no draw option 'flagship' in IMAQ oval overlay, even if the overlay IMAQ rectangle has this option?

  No simple alternative workaround solution? I am move 3D and tries to display the color gradient based on these movements on a picture 2D for clarity. I could I think using a rectangle, but the shape of the ellipse suits me better...

  Thank you and best regards,

• Anyway to adjust the weight of a Coverstitch IMAQ and IMAQ Overlay line?

  Is it possible to adjust the weight of a Point of recovery IMAQ?  I find it odd that this is not an option.

  If you mean you want a greater 'dot' or more online, as it takes a bit of work, because this option is not built on the.

  Instead of using the overlay point, use the the oval, then you can set the RADIUS want. or you can draw two lines (one vertical and one horizontal) crossing the coordinates of your point.

  I know... It's a bit tedious, but that's all I have in stock.

• Text on 16-bit image overlay

  I'm trying to text on a 16-bit image overlay.

  The overlay is successful (using overlay IMAQ Text.vi), but I would like to save this file with the overlay.

  I have been using IMAQ Write queue 2. VI to write the image as a .png and writes the image successfully, but not overlapping.

  I read this comment about overlays:

  Using overlay with a third-party Viewer features:
  When you use the functions IMAQ Overlay, a third-party Viewer will not display this information. You must use playback Image Vision of information with application software to display the overlay. To display a picture in a third-party Viewer, you can use the IMAQ merge Overlay.vi, who is a destructive function, which means that it replaces the underlying pixels by pixels bunk.

  So basically I would like to see the images later on a viewer of third parties, but when I use IMAQ merge Overlay.vi, the result is no longer the 16-bit image, I need.  It now becomes an RGB image.  Any suggestions on how to get a 16-bit image with superimposed text I can see outside LabVIEW?  Thank you.

  Hi jmeyer,.

  I think that's what you hear.  Take a look at the screenshot.  When you create a constant, or a control on the entry called Pixel color value it will create a dialog box that lets you choose a color you want to use when you click the command/consatant.  If you want to enter the actual value of the U32, you can replace this with a digital constant/control and enter the direct number you need.

  

• Draw the new lines on the graph of the intensity

  I'm trying to attract the XY axes by an arbitrary point on a graph of intensity. I can draw two lines across the image (suite of messages like this link below), but they don't really seem FDNE to the top one the coordinates I spesify. I know that I have to correct the fact that the vertical scale increases from top to bottom, but how do I draw lines to the (x 0, y0) position I spesify? It seems that the lines are superimposed on the image, but not related to the axes of the actual intensity chart.

• IMAQ text overlay, then Writfile in the right size

  Hello

  I use IMAQ to display an image, and then I want to draw lines by using the KING and text overlay, before exporting it as a jpg or bitmap.

  Please take a look at the façade attached jpg.  It shows a part of my image of front panel and I drew a KING of the line next to the line, I added text.  It looks great.  But when I use IMAQ write file 2 or IMAQ Write queue, then the KING and the cache are not correct.  Please look at the OverlayLV - you can see the line type (only now it is green), and the text is really tiny.

  Thanks for any help!

  Steve

  Hi all

  I thought about it.  Before adding the KING and overlays, I had to re - sample the image to the size of my IMAQ indicator.

• How to draw two points simultaneously on the image?

  I want to draw two points at the same time on an image. I tried to use IMAQ point overlay and IMAQ meter for point. But when I try to plot two points using one of these two screws, I can't find a single point is plotted. How to solve this problem?

If your image is zoomed out, the size can be to small to allow a good drawing of the point. Otherwise, IMAQ ecaple point works perfectly...
