• 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...

• How to draw a simple point?

  I studied the manual script and a lot of scripts but cannot find how to draw something simple (with pixel size 1 brush) to the point of coordinates X / Y and with a specific RGB color. Please help me with the corresponding VBA codelines.

  Rather than write the document in memory by filling in each pixel, it would be faster to create the image in a file, and then open the image. The code below performs a simple gray ramp

  // to keep demo simple vars are used for RGB
  // but could use array of solidColors or array of RGB values
  var r=0;
  var g=0;
  var b=0;
  var numberOfPixels = 65536;
  var imageFile = new File('~/Desktop/myImage.ppm');
  imageFile.open('w');
  imageFile.writeln('P3');
  imageFile.writeln('256 256');
  imageFile.writeln('255');
  var str = new String();
  for( p = 0; p < numberOfPixels; p++ ){
       str += r+' '+g+' '+b+' ';
       r++;
       g++;
       b++;
       if( str.length > 57 ){// lines can't be over 70 chars
            imageFile.writeln(str);
            str = "";
       }
       // the test is needed here to keep image 8 bit greyascale
       // would not be need with array of valid 8 bit colors
       if( r > 255 ){
            r=0;
            g=0;
            b=0;
       }
  }
  if( str.length < 0 ) imageFile.writeln(str);// last line
  imageFile.close();
  app.open( imageFile );
  

• 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!

• How to draw the 3D dice?

  Anyone know of a tutorial or an example to learn how to draw the 3D dice in Adobe Illustrator?

  I actually found a link to a tutorial on how to do it, but don't know if the announcement of such a link is allowed in the forum. (I'm new here.) He quite far up to a certain time and then it becomes unclear how one of the steps, or I don't know enough yet about using Illustrator to understand what he says to do. In any case, I get so far and then I can not look polished. I understand the basics for creating a drawing in 3 dimensions, so don't looking for this.

  OK, I got quite a breakthrough!

  I went ahead and have materialized to where I got the same result as above, where only the side '6' watch points, while the other two are blue.

  But then I was playing with the outline, making visible/invisible parts. That's when I noticed, there was the '4' and '5', but they were BEHIND the blue. Not before blue as I expected.

  It's simple. Only, I selected the two blue faces and used object/rearrange/send backward to position behind the faces dotted.

  After that, I was also able to select the blue edges and put a radiant on them. It is not yet exactly as this step in the tutorial, not until I find how the gradient tool. But I'm certainly happen.

  At this point, it looks like:

  

  And that is a SIGNIFICANT improvement on what I had before, if I say so myself. At this point, I'm probably on my way to following through with the tutorial, I started from.

• How to draw a trace of round clip exactly where you want

  I need to put some text bent in this white space where the circle but thin is just at the top.  I know how to draw a circle with the tool path ellipse and then insert the top text tool and enter the text.  What I am having a period very difficult is how to draw this way and re - its size so that fits it exactly where I want to go?  what I do now is that I put the cursor anywhere on the canvas, select the ellipse tool, hold down the SHIFT key for a perfect circle but when I call he's not where I want it. then when I choose the paths, I can not actually move the path to where I want to.

  If I go back and move my cursor down on the Board for re - draw the path, I still can't get it wherei like it.

  can anyone help at home.

  

  It isn't really round.  It is slightly flattened vertically.

  In any case...

  I have an Action which places the guides at 50% (50pc) vertically and horizontally to give me exactly in the middle of a file image, or you place them manually with view > new Guide.

  After doing that I would put the circular select this center point using the keys SHIFT and Alt (Opt) and get it more or less where I wanted.  Then change the selection in a work path.

  You can use a manual for remodel transformation and position who work the path by selecting it in the Trace Panel.

  Then place your text and if you need tweaking, use free transform again, but on the text layer.

  

  You can also use free transform to reshape the BG graphic to make around it.

• How to draw marker and ellipses in perspective?

  How to draw two ellipses in perspective and in addition the marker on the Center? What are the tools will I need? A tutorial would be very useful. I am beginner in Illustrator.

  My desired effect:

  

  You could do this with the one-point-point of view in a perspective grid.

  Just draw all flat objects and then drag them into the perspective grid.

  In order to draw objects, you can dive into the manual.

  See the parts on the shape tools and how to handle the anchor points with the tool pen.

• How to draw lines on a map with CS4

  I have CS4 and would like to know how to draw lines on a map image. I'm a beginner, so what do I do?

  It's about CS6, but CS4 would be a similar process:

  Here's a way to draw a line:

  

  Select the pen tool.

  

  Make a new layer which will be placed on top of the existing layer in the map.

  

  Draw a line with the pen tool, you can see the points that I made to create curves.

  Here is more information on the pen tool: http://psd.tutsplus.com/tutorials/tools-tips/photoshops-pen-tool-the-comprehensive-guide/

  http://www.Tutorial9.NET/tutorials/Photoshop-tutorials/pen-tool-basics-in-Photoshop/

  

  In Photoshop, you have to go back to the options bar and select "shape". This allows you to place a 'coup' on the path (line) that you just created. Otherwise, it will not be displayed.

  

  You can see the settings in the Option bar above, I did. I made that Fill was placed on 'none', and I chose a color for my race, but also a point of size for the thickness of the line until its visible on my card.

  

  It comes to the final.

  Good luck!

• How to draw a circle? duh

  How to draw a circle in photoshop elements 8 on a photograph highlighting one feature on the photo that I would like to point out to someone?

  I opened the photo, and it is the only layer.

  I can create as many layers as I want. So I create a.

  When the "edit" tab is active, there is no ellipse tool.

  When I click on the "create" tab, then the ellipse tool is present, but the layers box disappeared.

  When I click on the ellipse tool and draw my circle, he draws a circle solid obscuring what I would like to highlight. "Selection of stroke [Preview]" in the menu editing is greyed out.

  what Miss me?

  Yes, exactly the same thing to post-secondary studies. If you want a perfect circle, hold down SHIFT, and drag with the elliptical marquee, then edit > stroke (outline) selection.
