  I don't have a clue how to start drawing. No doubt its so simple I'm looking top...

  Any explanation would be appreciated!

  Sovereign salvation and Jacob!

  I associated some images to help you follow the excellent instructions of Jacob. Here you go:

  1. create a circle with a stroke and no fill. This eventually becomes thick circle on your phaser array, then give him a thick line and rounded tips.

  

  2. find the scissors tool and click twice on the way to circles indicating where you want to remove a part of the circle.

  

  

  Click along the line between the two points and delete the part.

  

  

  3 choose object > path > outline STROKE. What Jacob meant by 'give the desired time and filling', is that AFTER having chosen the line of contour, you now can fill this object with a color and give it a new trait. I chose to fill red mine and give her a 2pt to illustrate the difference.

  

  

  4 now, choose object > path > offset path. Be sure to check "Preview" to see the changes that you make. Must you really just change the offset value. I chose 5 px.

  

  

  Now, you have options.

  

  Since it's two objects, I selected the external object and removed the filling. On the inside, I removed the black line. This is the result.

  

  I hope this helps to illustrate the points of Jacob!

  See you soon,.

• How to draw a box under a trace of waveform?

  Hi all

  I have a graph of waveform of 3000 point showing a series of peaks.  For one of these peaks, for which I know the beginning and end clues, I would draw a box under the waveform on the graph, to highlight its position programmatically.  I don't know if there is a way to do it.

  I figured out how to draw cursors at the beginning and at the end, but finally I do for multiple peaks, and forest of cursors quickly becomes confused.  A simple shaded box works much better.

  Any ideas?

  Many thanks in advance,

  RipRock99

  A great thank you GerdW!

  The code LV was very close to what I wanted to do and is easy to use to determine how to make my code produces the result I wanted.  Basically, I added another form of wave to my chart, using my known indices x to set the values of Y for the areas I wanted to be gray as + infinity and leaving the rest to =-infinity.  I then plotted this second graph on top of the original waveform and the property node to set the fill indicator for - infinite.

  That does not answer the general question of how to draw a filled rectangle with the coordinates on a graph, but this does not fix what I wanted to achieve.

  Bravo and thanks,

  RipRock99

  PS: I'm including a preview of the result and a snapshot of the code used to define the property node programmatically.  I do not understand my code just as it is complicated, and I would also need to add a large set of data.  I hope that the pictures are enough to help someone else referencing this Council!

• I installed a trial of Illustrator from Adobe on my macbook pro. I want to draw a picture using the custom trace button but can not. Does anyone have any ideas how I could track custom?

  I installed a trial of Illustrator from Adobe on my macbook pro. This is the release of 2014 of the adobe Illustrator. I want to draw a picture using the custom trace button.

  I start a new document. Then I place my scanned pencil/color pencil, drawing, in the document. I tried to scan and then placing it as jpeg, bitmap and a tiff file. I tried scanning and place then, in color and in black and white. The scan mode that I use is flat. Adobe Illustrator allows me to select the default button and one of the eleven preset buttons (e.g. photo high fidelity), but cannot me click on the record button custom. The custom trace button is gray while all other buttons are white.

  Does anyone have any ideas how I could track custom?

  Just it trace, and then change the options later. The follow-up is 'live', you can press the buttons and see what happens.

So someone knows how to draw the smooth line that is low in some places and large in others? How to add this effect? IM using Illustrator CS5.

  He number of ways yu area can make a brush with a thick and thin profile, or create a profile for a stroke, or you can draw paths with even simple traits and then survive strokes and adjust the width then

  or you can draw paths with even stroke and the use of the width tool to adjust the widths.

  It is with the paths with the same shots

  Hello

  I found the code on the net, it works very well on j2me that even can be used also in blackberry below.

  public static Image createShadow(Image image) {
  
          int newX = image.getWidth();
          int newY = image.getHeight()/2;
           int out[] = new int[newX*newY];
           int row[] = new int[newX];
  
          for (int iy = 0; iy < newY; iy++)
          {
            image.getRGB(row,0,newX,0,iy+newY,newX,1);
            for (int i = 0; i < row.length; i++) {
                out[((newY-1)*newX-iy*newX)+i] = row[i] & ( (127*iy/newY)<< 24 | 0xffffff);
            }
          }
  
          return Image.createRGBImage(out,newX,newY,true);
      }
  

  Hope this will solve you problem.

  Please let me know if it solves your problem or not.

  The option is always there. You should press and hold on the image a little longer and then when the backup or copy of the window opens, save the Image is on the bottom row, but you may have to slide to the left to reveal. Once you find it, you can reorder the options by dragging the 3 lines to the right upwards or downwards as see fit you.

  Hello

  Normally, when I take pictures, they are 3264 × 2448 pixels = 4:3.

  How can I take pictures in 16:9?

  I know that I can crop a 4:3 picture later, but I'd like to see the correct size before taking pictures.

  Is it possible, or do I need an additional application for that?

• How to avoid the pictures to open automatically?

  Whenever I insert a SD card to download images Photos 1.2 app automatically opens.

  Quite annoying especially because I use this app at all.

  How can I avoid pictures opens automatically?

  Thank you!

  Photos doesn't have an option to disable the launch of all devices.

  When the Import Photos Panel opens, you should see a check mark in the toolbar 'Open pictures for the device'.   Clear this check box and Photos should not open again for this device (until you reformat the card).

  The automatic launch can be disabled for each camera separately.

  You can try this fix: this Terminal command allows to disable auto-start for any photo application, not just Photos.

  • Photos of quit smoking and unplug any camera.
  • Open a Terminal and paste this command and press return:

  defaults write currentHost - com.apple.ImageCapture disableHotPlug - bool YES

  • Restart the Mac. It is not necessary, but it worked for me after the reboot.

  I found this fix in a post of JadedEye ( leonie)
