• Get the string invalid Base64 of image of toDataURL() for the first time in 10 of blackberry webworks

  Hello

  I need to get the Contact image converted to string Base64 using BB 10 Webworks (blackberry.pim.contacts) I get only the contact.photos [0] .smallFilePath which returns the path to the phonebook file.

  Now, I want to get the image of this path and convert it to a Base64 string.

  Here's the javascript code :

  var img = document.createElement ('Image');
  var canvas = document.createElement ('Canvas');

  function getBase64Image (p) {}
  img.setAttribute ("src", p);

  Img.width = Canvas.Width;

  Canvas.height = img.height;

  CTX var = canvas.getContext ("2d");
  ctx.drawImage (img, 0, 0);
  Return canvas.toDataURL("image/jpg");

  }

  This means bad Base64 string of image for the first time. When I convert this string to the image it displays white screen. But returns a string in the Mithraeum and after conversion, display a correct image.

  I use Blackberry Z10 (OS 10) for the test.

  I think that the canvas is not drawing image properly for the first time.

  I have searched and tried many things, but not got success. What will be the solution.

  Thanks in advance.

  My guess is that the image did not load the source completely still. Setting the src / image loading is an asynchronous event, which means that your code will continue to the next line regardless of whether the image has loaded yet or not.

  After calling setAttribute instead of execute the code of the Web, you will probably need define an event on img for the load event listener. Once the image is loaded, you can then use the img with canvas variable to retrieve its data.

  Note that getBase64 will return immediately, so you may need to develop some sort of mechanism to wait before returning, or the asynchronous approach and integrate reminders for the success trigger the next piece of code.

• 46YL863: change TV channels - delay before the new image appears

  Hope someone can advise me please on an "issue" that's appeared recently with my 46YL863 TV.
  I say 'problem' rather than problem in case it's something to do with my settings, which is the cause.

  When I change channels I notice that there is a delay of several seconds of the current image to the new. I narrowed down it to this happens only when you switch from a HD channel to a one SD card, or from a SD card on a HD.

  In these circumstances the screen will first black, then blue and after a couple more seconds the new image of the string will appear.
  Switch between HD or SD channels and the new image appears almost immediately.

  This happened before the last two days, so either a fault has developed or I changed a setting in some way.

  I tried other plugs of HDMI input and the situation is the same.
  Any suggestions please?

  Thank you.

  > I tried other plugs of HDMI input and the situation is the same.
  This means that you are using an external decoder which receives signals from TV?

• Length of the string

  Hi all

  I intend to measure the length of the string and the length of the Arc in a gray-scale image. Please advise.

  You need to find to the first circle or outer circle?

  Part of Mathematics:

  The length of the rope of calculation, to find the RADIUS and the angle under which is seen in the center of the rope or perpendicular to the distance between the string and the center of the circle: once you have these settings, you can calculate the length of the rope using formulas:

  Source: http://www.mathopenref.com/chord.html

  Similarly, you can get for the length of the Arc: http://www.mathopenref.com/arclength.html

  Part of image processing:

  -I think that you can get the radius of the internal or external circle based on your requirement, using IMAQ detect forms.

• IMAQ Unflatten string image

  Hello

  I use the IMAQ flatten image for the vi string to flatten an acquired image and write it to the binary file. Later, when I read the binary file and try with it chain unflatten, I get an error message:

  74 error to Unflatten channel into frames get & Process.vi

  Possible reasons:

  LabVIEW: Memory data structure or corrupted.

  What I am doing wrong? I've attached screenshots to flatten and unflatten operations.

  Thank you

  Soheyl

  I actually found the problem. For future reference: I added a flatten the IMAQ Image to a string on the diagram to unflatten and wired his output to the terminal 'data type' binary file reading. May not be a more elegant solution, but it works.

• How the string output to a common indicator?

  Hello

  I have a sequence of battery with 10 picture sets, there is a wait to delay of 2 seconds between each image. I have a common indicator of channel set and I want to output a string to this indicator in the first framework before the codes between frame 2 frame 9 execution... and I would like another string to the same indicator on the latest image to indicate all the completed exit code. But I find that there is no way to share the flag by two constant string of different chassis. Any idea? Thank you.

  Use the variable value or local property of the node of this common indicator in all sequences

  My understanding is that a Bitmap is a full image, uncompressed, and the Blackberry uses 2 bytes per pixel to represent the color, then the image of 2048 * 1024 means about 4 MB of storage.  It's not bad, especially since I suspect that you have more than one of them.  And of course the follow-up to this question is how you view this image size on the device?  Seems to me that this file size is a bit of an overdose.  But even if you don't need it, have you considered using the scale parameter of

  Bitmap.createBitmapFromBytes

  scaling of the image according to a more reasonable size before you create the Bitmap image?

• Keep the text perpendicular to the base line when you use the string.

  Is there a way to keep the text perpendicular to the base line when using the warp function?  I'm trying to reproduce a decal with curved text.  When I use the string to get the text that is curved like the original, the letters are slightly tilted.

  You could try to make each letter on a separate text layer, then use Image > transform > free transform to adapt the letters in place.

  A lot more control over the placement of the letter and size that warp text offers.

  

• source code in the string form

  Hello, I would like to ask, if it is possible to set the entire source code as a string variable.

  I need to do a complex search and replace and search dw and replace funcions with regexp does not,

  I want to work with the entire source code as variable and use javascript to change something

  no idea how to do this?

  conrectly I need to convert this:

  "< img src="/blabla/blabla/image.jpg?blablablabla "alt ="alttext"class ="image"width ="100"height ="100"/ >

  TO:

  < component format = "url" name = "component/image.jpg" start ="& lt; img src = & #39; "end ="& #39; ALT = & #34; alttext & #34; class = & #34; image & #34; width = & #39; 100 & #39; height = & #39; 100 & #39;  / & gt; "/ >

  I don't think it is possible to find and replace and regexp, mainly because the image attributes can have different order. but the use of some functions in javascript is simple.

  do you know how to get a source to the string, and then again on the document?

  Thank you

  Hello st3n,.

  Not sure I understand exactly what you're trying to do, but in the Dreamweaver API, dom.source.getText () will be the source of the entire document as a string. You can then manipulate it with the JavaScript code with Regex functions.

  Then dom.source.insert () allows you to insert some source code that you want in the document.

  You can find more information in the section Help Center, API of Dreamweaver, Code, Code display works.

• Help make the second image in the slideshow load a button.

  Hello world.

  Can someone help me with the actionscript code to one of my images in a slideshow (whose images are linked externally through actionscript)

  load a button which is accessible only when this specific image is displayed.

  for example-image 1 - No button but image 2 has the button, button 3-no image, image 4, no button... and so more.

  Here is my script for the slideshow and prev buttons and following

  var totalSlides:Number = 6;
  var currentImage:Number = 0;
  var imagePath:String = "images/ad";
  var imageName:String = "announcement";
  var imageExt:String = ".jpg";

  var adImages:MovieClipLoader = new MovieClipLoader();

  function loadSlide() {}
  adImages.loadClip (imagePath + currentImage + imageExt, "adImages_mc");
  }

  loadSlide();

  this.prevSlide_btn.enabled = true;
  this.prevSlide_btn._alpha = 100;

  this.nextSlide_btn.onRelease = function() {}
  _root.prevSlide_btn.enabled = true;
  _root.prevSlide_btn._alpha = 100;

  
  If (currentImage < (totalSlides - 1)) {}
  currentImage ++;
  loadSlide();
  }

  If (currentImage == (totalSlides - 1)) {}
  _root.nextSlide_btn. Enabled = false;
  _root.nextSlide_btn._alpha = 50
  }
  }

  this.prevSlide_btn.onRelease = function() {}
  _root.nextSlide_btn.enabled = true;
  _root.nextSlide_btn._alpha = 100;

  If (currentImage > 0) {}
  -currentImage;
  loadSlide();
  }

  If (currentImage == 0) {}
  _root.prevSlide_btn. Enabled = false;
  _root.prevSlide_btn._alpha = 50;
  }
  }

  
  Im a beginner but know some actionscript.

  I really appreciate the help.

  Thanx

  I guess that the button that you want to display is not indicated for anywhere in the code that show you.  What you can do, is make the button visible/invisible in the function loadSlide.  This assumes that currentImage = 1 is the second image, change only if it is actually 2.

  function loadSlide() {}
  adImages.loadClip (imagePath + currentImage + imageExt, "adImages_mc");

  if(currentImage == 1) {}

  certainButton._visible = true;

  } else {}

  certainButton._visible = false;

  }
  }

  is there a better way to load the thumbs so that I can get better references to every inch, as for example loading them in order, then adding the click event listener to the thumb itself rather than the thumbContainer that holds all thumbs?

  Thanks in advance!

  Please define path before each URLRequest. You must have at least 4 tracks in the code in methods:

  URLRequest

  loadFirstImage

  loadFirstImage

  loadThumbs

  myImages [e.target.name] .url

  e.Target points at thumbContainer

  e.Target.Name is the name of the instance of the thumbContainer

• Is it possible to know the file name of the loaded images?

  Hello:

  I have a folder containing images named 01_image_name.jpg, 02_image_name.jpg, 03_image_name.jpg,... names that I read with a PHP script. Then I wrap each image loading and wait for all are responsible to view

  1. the PHP script reads the names file and returns a string with names separated by a "|" char, then I use the split to store in imagesNames table method and sorting
  2. I loop table of imagesNames hollow loading images
  3. anytime a new image arrives I push imagesContainer table and check if all the images are loaded to show them

  The problem is that there is no guarantee that they arrive in the same order they opposed. So, how I sorts the array imagesContainer of file name, i.e. in the same order that they are imagesNames table?

  Thanks in advance

  function imgLoaded(par:Event):void {}

  trace ("the loaded image comes from this url:" + par.target.url);

• How can I display the first image of a built-in clip?

  I prepare a presentation for my 10.11.16 retina, with Keynote 6.6.1 MacPro OSX. I want that it contains clips integrated to my films. I chose the simplest theme - plain black.  I drag and drop these Quicktime movies or .mov of iTunes to a new black slide in Keynnote.

  When I'm in mode Navigator or Light Table etc, what I see is a series of black images - although if I click with the mouse the video will play. How can I see the first frame of the movie, and don't forget that it will start when I move to the slide, so that I can see the order of presentation, or know what's coming?

  You see black because it is what is contained in the poster frame, which is the first frame of the video by default.

  To change the original image: click the video on the slide to select it, then go to: Inspector > Format > film

  either drag the corrector, or enter a number in the box, here I'v entered 4 seconds for the poster so frame the frame of departure:
