Draw colorful triangle

• Drawing a triangle shape through a script, reading a limits of the selection and the pointer of the mouse?

  Hello...

  It's a little more complicated, I guess...

  

  I am looking for a way to automate the work I do for a manga magazine - cartoon or whatever they are called... I have a dialog box in an oval shape that is already formatted with a style of object to look like the oval in the left part of my image. I would like the script to read the position of the mouse pointer - I ran the script after selecting the oval and the place where the oval must point hover with the mouse... (In the picture so you can imagine my cursor somewhere in the lower left of the image, in the second part of the image corresponding to the angle of the triangle) I imagined this operation in at least two steps, the triangle (arrow) of the oval is a separate object (I would join the two forms later). The triangle can be with streight lines or maybe a little bent, for a most desirable look. I have no idea where to start, for now I create ovals and duplicate the triangle an old and position (+ turn) until I'm happy, after that I could join them. I hope the picture can better explain what I'm looking for.

  I know it is hard work - I think it may be useful for others, as it would be a good challenge for the very smart Scripting Guys of this forum...

  Thank you..

  Maybe you can use a single line to indicate the direction and the location where to that you must point.

  I did Speeech.js to illustrate this approach:

• Point cloud: color gradient

  Hello

  I can't find an example where I can create a custom class plot. I have to be able to line the plot of color based on the value of Y and make it look like a smooth gradient. Ideally, I would like to change the size of the line as well. This would allow me to "draw" the 3 variables using a 2D graph. I started (VB.Net):

  Imports NationalInstruments.UI

  Public Class clCustomPlot

  Inherits from point cloud

  Public Sub New()

  MyBase.New)

  End Sub

  Protected / Sub OnBeforeDraw(ByVal sender As Object, ByVal e As NationalInstruments.UI.BeforeDrawXYPlotEventArgs)
  End Sub

  End Class

  But VS tells me that:

  Void of MeasStudioGraphLineColour error 'OnBeforeDraw' cannot be declared 'overrides' because it does not replace a sub in a base class.
  Thanks for your help,

  Nicolas

  I got it to work! For all those who are interested, here's a VB.Net custom dispersion diagram that will show you how/color along the line of control.

• Paint colors

  I can't color to view or print in paint.  Is there a setting somewhere that I have to use?

• HP PSC 1317 AIO - you need a color cartridge to print in black only?

  Hello

  Just a quick question to run me to the store twice save.

  A totally black HP 56 + HP 57, a color with a little ink left would be enough for printing in bulk in black only? I'm not sure how this works because I was told that some printers draw on the color cartridge to compensate for the dark ?

  Thank you!

  Hello

  Almost all printers draw color inks to print in black, it is the rule of normal color mixing. We can stop this using 'grey levels' option on the printer or applications (for example, Word...). BUT the printers need color inks to protect the print head (please don't ask me why) that is why they will stop when no good no color ink cartridges installed.

  Kind regards.

• Impossible to color in the new layer * new user *.

  

  What I wanted to do was draw/color the hands separately so I used the Lasso tool and describes the hands at Base of layer 1. I used "Layer by copying" to separate the hands.

  

  When I tried to color in it, I can only color in the previous layer [layer 1 Base] under him as you can see from the layer panel on the right side.

  So I tried to block the Base of 1 layer and 'Hide' by pressing on the "eye" icon. And when I wanted to color, this popup came.

  Is there a technique I use to separate just the hands or any part of the image?

  It seems to me, on the layer 1, you can paint the area around the copied area. What will happen if you make a selection of the segment on layer 1, then select > Inverse. You did a selection on layer 1. Did you reverse and Cmd + H to hide this selection?

  I suggest you choose the Base Layer, make your selection, then Cmd + J. He will place the segment on a new layer in a transparent skin and automatically place you on this layer, ready for painting.

• Triangle without the base.

  I wanted to draw a triangle without the base as one on the roof of a House. So, I drew a triangle and tried somehow to remove the base, but I have had no results. How can I do?

  Murr,

  Then drag the segment of the path with the selection background direct tool, including this anchor in the middle and press the delete key once.

  If you wish, you can get rid of the intermediate Anchor Points, simply by clicking on it with the tool remove an anchor point.

• Out of the boundaries of drawing

  I have a work at home who want this program:
  
  Demonstrate the use of the exception handling to catch errors even divide by zero and the drawing out of the limits.
  the program allows the user to get the 3 points, that the program uses to draw a triangle. Then, allow the user to enter a value and use it to scale of the plu triangle or less the geographical center of the JFrame. Make sure you handle the case where a zero entered under scale. Make sure you handle the case where the points of the triangle to go outside the JFrame (throwing an exception!).
  
  I can draw the triangle, but I don't have an idea how the triangle is off the edge of the JFrame.
  
  Is there a method or class, or what I can do?

  You can create the triangle with the tool polygon, delivered with the Rectangle tool (click and place the cursor until the other tools fly away), then the effect > esthetics > corners rounded. You can object > decompose the aspect if you have six anchor points.

• the color scheme does not work as follows.

  Question:

  Suddenly occurred the following phenomena, using PSE - 9 on Windows 7.

  After you set a white canvas at at the beginning, all drawing colors cannot be choiced but made with gray colors in different light depending on the lightness of the color.

  However, without the Web, they can be chosen as usual. So that I can't use my PES and he might there have found several flaws on the cross on current usage.

  I tried to have it uninstalled, installed recently by WAA and re-powered disc again, but nothing has not improved.

  I'm stuck in distress.

  I am very appreciated if you don't show how to improve the situation. Thank you.

• Triangle

  Can anyone help as I would like to create a triangle of the eps with curves (instead of points), but don't know how. I have Illustrator version 8. Could someone do that for me for a tenner as I am unemployed and pretty broke at the moment. I will pay by paypal if anyone can help. I need to open in Illustrator version 8

  Val

  Howard

  You can draw a triangle easily by drawing with the polygon tool and press the cursor down some time reduces the amount of sides to 3.

  Illustrator 8 is old enough then to cut corners, you will have to do it manually as I beliueve the rounded conrers filter does nto exist. You can use the other convert too to round the conrers manually.

• How to draw an arrow?

  Is there a quick way to draw an arrow in Flash? I saw 2006 assignments who say there is no, but I was wondering if there is a way in CS4?

  Thank you

  Laura

  Click the polygon tool (click and hold the rectangle/Oval tool if you do not see polystar), select 3 side and draw a triangle.  Adjust the width/height according to your needs and add a line with the line tool or the rectangle.

• Increase time to shoot 10 000 triangles

  It is a test program to measure the time it takes Flash to draw a triangle 10,000 times.

  The app (code below) called runTimeTest() every N seconds that draws the triangle 10,000 times.

  Now for the "interesting" part: each call takes processor more until after he goes on the 6th or 7th call for "Infinity" (see screenshot of the Task Manager)

  Bug weird or explainable?

  c.graphics.lineTo (x 1, y1);

  c.graphics.lineTo (x 2, y2);

  c.graphics.lineTo (x 0, y0);

  c.graphics.endFill ();

  }

  }

  Tested myself, and indeed it takes an increasing amount of time to draw. Definition of cacheAsBitmap did not help... What you can do however is clearly the figure between loops with: c.graphics.clear (); just before your loop for. With that I get useage processor max 20% on successive draws.

  It takes more time every time is not serious because create you 10 000 vector shapes in your 'canvas' every time... just because they are on top of the other - there are still 10 000 forms in this object. Then 20,000 on the next pole, etc. Once you get 30-40 000 forms in the display list you ask just trouble.

• Cut out the portion of the form

  I have minimal experience with Amnesty International and am learning that I will. I have re-trace in Illustrator, a company logo, and I need to know how to do the part of the triangle of the letter has to be transparent? I used the pen tool to trace the outside of the letter A, then used to draw the triangle in the middle... but when I went to create a .png, I noticed that the white triangle is always there. If I don't choose no fill color, so you don't see it at all and the letter A has the hole should be.

  How can I make just the cut in the shape of triangle of the black letter A?

  

  Thank you in advanced for your help!
