How to draw simple shapes in PF_EFFECTWORLD / PF_LAYERDEF

Hi, AE community!

My question is perhaps a little strange, but I'll try

Is there (SDK) a methods to create Visual as forms a circle or oval, line, perhaps something like a point of color and pen?

What I want to get:

Read data (color, position) of composition/layer source and create small shapes with the same brightness and the same position in the new world, then mix it with the output.

Available solutions I see:

1. with the help of suites, as a

Suites.FillMatteSuite2()->fill()



with a form of circle in the arguments. Fill() receive a PF_Rect, I know not, but might a similar solution undeclared in SDK_Guide ?

2. with the help of the DrawBot with bows or similar courses with filling.

I found different examples 'ColorGrid' and 'CCU' practices, but with the help of DrawBot confuses me, because in my PF_OutFlag_NON_PARAM_VARY project used Pavilion and I should call Render function to calculate the particles of the post each time and move them. With DrawBot (I understand the Guide), I have to use DrawBot in the Draw event. Or maybe it's all wrong way and DrawBot are not created for tasks like my.

3. using an iteration suites.

In the examples of projects, I found complex loops with iterate world of entry and draw pixels in a special for the area of the circle (if I understood). In other words, I can create array with (special for my task) pixel coordinate system, creating points for particles in this table, then loop through that array and move at the same in the world of the output. OK, if this way right, then I need to use mathematics to calculate ovals or circles, and then calculate the feathers or aliasing for this form. The problem requires clear that computing power

Maybe all these solutions won't and I can use another way to solve my task? There may be some functions to draw different shapes and I missed them in the SDK Guide? I'm afraid to reinvent the wheel, because so far got only square

Anyway, thanks for any advice or the way to solve my problem!

Well, I found answers to my questions. If someone needs my help, please, write them in this thread.

  • How can the PSD CC 2015, I remove the ToolTip of information when you draw a shape layer?

    HI -.

    I don't know what his name but on win 10 / Photoshop CC 2015, whenever I have to draw a shape layer, I get a little window indicating the angle/length/width/etc, I draw.  While I don't know that it is a great tip for some people - for me it's annoying and it covers what I'm trying to see that I draw.

    On 10 of win / Photoshop CS5 - I do not have this information box.

    I looked in preferences under Interface and sliders, but couldn't find out how to turn this "feature".  (Probably because I don't know what his name.)

    How do I turn it off?  How can I disable contact information indicator bit appears so when I draw a shape layer?

    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;

  • 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 circle in photoshop using script, do not pathitems

    You don't want to use a shape layer? You can use scriptlistener to record make a circle for it, then put in a variable for values. You can also use scriptlistener to make a round selection and then caress than. You could also do a bunch of small round pieces that you can fill out and then use a little math to place a series of them in a circle.

  • 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!
