• Drawing a pixel logo?

  Hi, I'm fairly new to Illustrator. I have a company logo with a single format, which is the PNG format. Unfortunately, the designer who created our logo could not get back to us with a logo nice and crispy, so that's where I have to jump in. I want to know how to find the logo and do exactly like the original. The logo looks very simple to do but his question just of tracing. Can anyone help? The logo is below for those who ask

  

  Looks like you're fishing for a 'gift '.

  I don't blame you, but I think that you can do. Just make it work with the pen tool.

• How to draw pixel data in a layer of generator

  Hello

  How can you draw arbitrary RGBA data in a layer?

  Is there an API that do this directly? So I'm guessing not, could go in the target box, by selecting each pixel and then by a fill with the color needed operation - or maybe draw each pixel with the pencil tool, etc. Is there a standard way to do such things? I guess people must have had to do, but I couldn't find any discussion or the code examples.

  If the use case is not clear, I call generator.getPixmap on a layer, then I change the data and want to draw the results in another layer. It is through generator, generator of code or JSX would work (although the API generator would be much easier to work with).

  Thank you!

  Hi, it's weird, it worked, maybe it's because the progress bar, I know that sometimes it crashes Photoshop when you have a palette window... I tested the script with the latest version of the CC on Windows and it worked fine... In any case, you can do this effect desired directly in Photoshop and interactivity as well. I created a screen on how I did it:

  

  This way when you edit the smart object it will automatically update the margins of threshold. All you have to be careful is not having a black with the glow of the 0 in your color. You can have it with a value of 1 instead.

• How to segment joints cracks between them using the wizard of vision?

  I built an application that processes the images taken from a camera high resolution with IR lighting. I noticed some cracks in the pavement could unite or are having joints that are cut into the concrete or ashalt. I need to distinguish between the cracks and joints so that I can classify and record their location on the image for a worksheet. I saw where someone has used the segmentation of the circular basin of separation is opposed, but it works for cracks (lines) so? If not is there ideas for 'disconnect the cracks in the joints. I have attached my script assistant of vision and an image of the sample. Thanks in advance for your advice.

  I tried the features of the morphology and the problem is it joining a crack for joints, if it was them that intersect and then counts as a single object/shape. I ended up finding a solution really good. I used the detection of edge advanced prior to dilation image, then use those points to detected lines to extract the joints and obtain the necessary information (width, length, position), then use the positions draw black pixels on the joints on the binary. This allowed me to get the information that I needed for the joints and also remove them from the binary image so that I can treat the cracks by flying over in he picture. Now, I just need to find a way to get some of the other object that the threshold is removed so that I find myself with just the cracks. Thanks for the help. Its always good to get some ideas from someone looking to another direction.

• Transparency and color precision

  Hello

  I created a PNG with only 1 color: white, but with varying degrees of transparency.

  My idea is to cover this png on top of any solid color and create a brilliant UI, regardless of which is the background color.

  However, when I applied, I don't see that on 5 different shades of white, so theoretically it should be 255 different shades.  Needless to say, it looks terrible.

  Do you have suggestions on how to make this work better?  Could I manually draw the pixels using Graphics.drawARGB for best effect, or is this a limitation of the device Simulator or blackberry?

  If you have any suggestions on how to create the desired effect, I would greatly appreciate them.

  I'm sure that transparency is 8-bit (0-255), but the transparent color is mixed with the underlying color, and the result is 16-bit color. I'd do a few tests to determine the best combination of what you want. So do images of 32-bit normal and then save them as 16 bit images to see how to work the colors on the scale.

• Brush in a straight line with the decrease in pressure

  Just past the CC on Mac 10.11 CS6. I used to draw highlights on products using my mouse and the Brush tool. C.; I think I picked a px brush 9 with 50% hardness, clicked then moved the cursor all holding the SHIFT key and click New. I could then draw a straight line, and I think I've adjusted the flow to get the color to start at 100% and cone of 0%.

  I'm now trying to figure out how to accomplish the same thing in CC, but I'm having a hard time to understand.

  Again, it is with a mouse, not a tablet.

  Did had perhaps put opacity to flow to Fade?

  

• WYSIWYG lines in photoshop CS6?

  In CS6, is there a way to draw a line where you see that you draw in reality and not an outline of the line?  I try to draw single pixel non-anti-aliased lines at 800% zoom and I just a glimpse of a line instead of pixels.

  Hi Daveperson,

  The shape tools have 3 different drawing modes:

  1. Shape layers
  2. Paths
  3. Pixels

  
  

  The first 2 Create vector shapes, while the last created raster forms. If you select Pixels you can uncheck Anti-alias , who will then do what you want.

  

  Then select the line tool and change the pixel mode.

  Thank you

• Component FLVPlayback + HTML5

  For a HTML5 Canvas project, I am in need to use imported FLV videos (screen Green w / alpha channel), in order to publish highly compatible on the web. Because the FLVPlayback component is not supported in the HTML5 draft, is it a possible workaround to achieve what I want with the Adobe software? If not, could I get informed how this could be done with other programs/techniques?

  While there has been "solutions" in the past, the answer is ultimately the codecs that support this are limited and unreliable. You will need to use something to really pull this off is to separate your alpha channel in the video, then using an invisible Web to deal with video-based alpha channels (reading pixel by pixel to determine what percentage of opacity to draw single pixel). Some people use a specific color in the video as the channel (for instance if you just need red text, and then use a different background color as the alpha). You draw then that a visible canvas after calculation. It's very unideal but there is no "best way" to do this now, external Flash.

  A Quick Search will show you the techniques that I talk, but none of them are drag and drop the approaches to the problem. They require JavaScript, good video types and a bunch of treatment.

• Performance of the canvas

  I've been testing the performance of canvas on a very fast machine (quad core Xeon) by recent NVidia graphics cards, but I am unable to make the video full screen 1920 x 1080 with this configuration using the Web.
  
  It's simply too much hope for or am I missing some obvious performance enhancements?
  
  Here's the code I used:
  

  import java.nio.ByteBuffer;
  
  import javafx.application.Application;
  import javafx.scene.Scene;
  import javafx.scene.canvas.Canvas;
  import javafx.scene.image.PixelFormat;
  import javafx.scene.image.PixelWriter;
  import javafx.scene.image.WritablePixelFormat;
  import javafx.scene.layout.BorderPane;
  import javafx.stage.Stage;
  import uk.co.caprica.vlcj.component.DirectMediaPlayerComponent;
  
  import com.sun.jna.Memory;
  import com.sun.jna.NativeLibrary;
  
  public class VLCDirectTest extends Application {
  
    public static void main(final String[] args) {
      Application.launch(args);
    }
  
    private DirectMediaPlayerComponent mp;
  
    @Override
    public void start(Stage primaryStage) throws Exception {
      NativeLibrary.addSearchPath("libvlc", "c:/program files (x86)/videolan/vlc");
  
      BorderPane borderPane = new BorderPane();
      final Canvas canvas = new Canvas(1920, 1080);
      borderPane.setCenter(canvas);
      System.out.println(">>> " + canvas.getGraphicsContext2D().getPixelWriter().getPixelFormat());
      Scene scene = new Scene(borderPane);
      final PixelWriter pixelWriter = canvas.getGraphicsContext2D().getPixelWriter();
      final WritablePixelFormat<ByteBuffer> byteBgraInstance = PixelFormat.getByteBgraInstance();
  
      mp = new DirectMediaPlayerComponent("RV32", 1920, 1080, 1920*4) {
        @Override
        public void display(Memory nativeBuffer) {
          ByteBuffer byteBuffer = nativeBuffer.getByteBuffer(0, nativeBuffer.size());
          pixelWriter.setPixels(0, 0, 1920, 1080, byteBgraInstance, byteBuffer, 1920*4);
        }
      };
  
      mp.getMediaPlayer().playMedia("L:\\test-movies\\2012.mkv");
  
      primaryStage.setScene(scene);
      primaryStage.show();
    }
  }

  It works, but it hickups and distorts a lot when it hickups. Lower the resolution of 1600 x 900 to say, it is almost smooth. Lowering still gets the expected 24 frames per second.

  Try to use IntBuffer, it's get-buffer possible bytes converted per pixel. I think if the pixel format and the width of the scan line corresponds,
  System.arraycopy (...) is used instead of a loop / conversion on each pixel. It should be enough to download full HD of 25 frames per second.

  There is also no need to use the node of the Web, you can use WritableImage.getImageWriter () .setPixels () with IntBuffer.
  It is possible that the canvas node distributes all the draw lots / pixel in the render thread events and copy the array / buffer again.
  I'd be curious what performance you get.

  And well, I didn't know you could so easily integrate VLC =)

  -----

  PS:
  Oh too bad for me that the WritableImage has a 'ByteBgraPre' (premultiplied) PixelFormat. Then
  imgWriter.setPixels (0, 0, w, h, PixelFormat.getByteBgraPreInstance (), pixels.asByteBuffer (), w * 4);
  was a little better than:
  imgWriter.setPixels (0, 0, w, h, PixelFormat.getByteBgraInstance (), pixels.asByteBuffer (), w * 4);
  For opaque, premultiplied images is not serious anyway. I managed to get 45 fps with upload of 1920 x 1200 pixels.

• drawGraphicsData animation...

  Hi all

  So, it's out of my comfort zone, but I'm trying to come up with a proof of concept for the bottom. [traceImage] literally does what it says, however, I am trying to achieve a function which should facilitate tracing: that is to say: I want to animate this line: curves.graphics.drawGraphicsData (gd); or find a way to make the line look like, it animates around the bitmap tracing.

  I really have no idea where to start, but I'll be scouring the interwebz all day for a preview, so if someone has knowledge on how to create the illusion that the curves. is animation, I would be extremely grateful.

  THX in advance,

  ~ Chipleh

  {

  While (imageContainer.numChildren > 0) {}

  imageContainer.removeChildAt (0);

  }

  BM.visible = showBitmap;

  imageContainer.addChild (WB);

  curved var: Sprite = new Sprite();

  imageContainer.addChild (curves);

  var gd:Vector. < IGraphicsData > = new Vector. < IGraphicsData > ();

  var strokeFill:GraphicsSolidFill = new GraphicsSolidFill (0 x 008800, 1);

  GD.push (new GraphicsStroke (1, false, LineScaleMode.NONE, CapsStyle.ROUND, JointStyle.ROUND, 3, strokeFill));

• IMAQ draw pixel color?

  Hello

  I wonder what are the valid values for the 'pixel color"entry for the Draw.vi IMAQ. I use RGB32 (U32).

  I could not find information on this in the service of assistance of the VI or on the web. You can enter the values in the s 10,000, which clearly has an effect on the color.

  I expected separate R, G and B inputs and do not know how they combine.

  Thank you!

  The color value is six-digit hexadecimal representation of RGB values.

  -As the first two digits representing the hexadecimal value of R, and two digits to G and the last two for blue.

• Microsoft PAINT - how can I amplify a drawing are in paint, enlarge the concentration of pixels?

  Microsoft PAINT - how can I amplify a drawing are in paint, to increase the concentration of pixels?

  Hi Uuj112,

  Concentration of the pixel depends on the quality of the image. If the image quality is very good, then you might be able to enlarge the picture with good quality.

  You can try to resize the pixels in Microsoft paint. Try the following steps.

  1. open Microsoft paint.

  2. click on the Home tab > resize

  3. click on Pixels and trying to adjust the horizontal size of the image.

• Stylus compatibility Adonit Pixel with Photoshop &amp; Illustrator sketches draw?

  I contacted Adobe support on this issue and that told you to come here for the fourms for help. I hope that Adobe can provide some information. I've already sent Adonit all this directly, but they said it's application developers to answer me.

  I recently bought the Adonit Pixel pen and tried with many applications. Because I have a subscription to creative cloud, I was really hoping to use the pen with sketch and draw, but unfortunately it is not compatible with the application at this time. This http://www.adonit.net/jot-ready-apps/ page lists current compatible applications. I'm working on an iPad Air be said by the way.

  You will add compatibility soon for the Pixel with sketch and draw lots? I'm trying to decide if it is worth keeping the stylus if I won't be able to use it how I intended also. It is also a great pen.

  Hi Rachel,

  I talked to the product manager for applications of design, and he said he thinks the next updates for drawing applications (they should be available in a few weeks) should solve Pixel problem does not.

  I know you are trying to decide whether to keep the pen... I hope this helps.

• Draw with Adonit Pixel?

  Adonit Pixel appears to fit with the draw on my Ipad Mini but works very badly. The pointer is 5 mm or more away from the tip of the stylus, but even taking into account that brands are inaccurate in the placement and pressure variations are causing or not at all.

  I downloaded and installed Procreate.and find it works perfectly, which proves that the problem is with Adobe applications.

  I am doubly disappointed because I am an Android user, frustrated that Adobe drawing and sketches are still available on my platform (my Creative Cloud subscription costs the same but without the same level of service). I just bought the Adonit stylus for use with an iPad, so I could access the Adobe applications - find now that it does not work properly is ridiculous.

  Rachel,

  I just checked with one of our engineers, who gave me a a preliminary version of the stylus and it works on my iPad 2 Air in sketch and draw lots. (He wondered if maybe something has changed since then, he was officially presented, but don't think that this should be the case.)

  Looks like maybe he didn't 'connect', so I just wanted to check that you see in the menu of the pen after you connect (in an open canvas, tap the gear icon then the stylus, you should see it listed in the context menu).

  Let me know.

  Sue.

• Pixel drawing does not work correctly.

  It's incredibly hard to explain but I'll try.

  For the most part, zoom in the Web and the design with a single pixel works very well.

  However, occasionally and just often enough to bother, in equal amount the pixel is either placed a square on the side (in all directions) or not set at all. As if I had never clicked.

  I can't find any text explaining this online, because it's so hard to look for the problem in one line unless it is interpreted as something else.

  I draw pixel by pixel very often I see sprites of retro games.

  It is a deal breaker for me if it cannot be fixed.

  I have no idea where to start.

  Just to answer a few simple questions.

  I'm clicking very close to the center of a square of Pixel with the reticle entirely in the area. I appreciate the temptation of putting this on my poor judgment by I can assure you it isn't.

  by dragging the pencil tool in the pixel problem works, so this isn't a question of layer, or stray white pixels on a top layer or something like...

  With perseverance, that I get drawn pixel (zoom, shaking the camera position), but really, I don't we should not have to keep faffing like that every 20th point I draw!

  Any suggestions?

  Hello Chuck!

  It seems that the reason was the grid.

  I had him to give me a guide where a sprite ends and the next begins.

  After moving to a much larger size of sprite grid caused this weird missteps where I could click the pencil tool.

  Once I turned off grid the problem disappeared completely.

  Thanks much for the reply

  Forum behaved a little oddly when I wrote the question and I do not think it through. I would have mentioned that I had found the solution, if I knew he did it here.
