Illustrator SDK :: How To Determine If Point Is Inside A Closed Path
Mar 20, 2013
I am developing a plugin for Illustrator CS5, 6. I have a scenario which requires the plugin to place a text frame inside a closed path art. How can I calculate the proper destination coordinates? The path art can be a curve or a rectangle, any shape. I need to place the text frame inside the path such that no part of the text frame overlaps the boundaries of the path art.
I looked at the forum and found the following thread: [URL] .....
Here, its stated that the method AIPathfinderSuite::DoFrontMinusBackEffect of the API did the required task. I tried the same but couldn't get it to work.
My first preference is to use the Illustrator SDK, not any third party libraries.

I have a closed object and a line outside this object. I want to take anypoint on this polyline as a reference and check whether that point is lying inside the closed object or outside.

Do I need to create a closed path first? Don't know how.

I'm using Illustrator CS6.I'm working with closed paths on an illustrated character. I have a leg overlapping a body for example. The leg is essentially a 4 sided shape but I only want a stroke on 3 sides. On the 4th side I don't want a stroke on it so that the leg blends with the body. I first thought about using the shape builder tool to merge the 2 shapes to see what that would look like but they won't merge for some reason.
Then I tried to use the width tool to drop the stroke on the 4th side down to a 0 width for the side I want ... but that didn't work either.how I can change a closed shape so that a section of the shape has a different stroke colour (i.e. none!) from the rest of the shape?

I have a stringy object which is a single closed path. The fill disappears where it overlaps itself. Can I prevent that?

Draw closed paths with the Pencil toolSelect the Pencil tool.Position the tool where you want the path to begin, and start dragging to draw a path.After you’ve begun dragging, hold down Alt (Windows) or Option (Mac OS). The Pencil tool displays a small circle (and, in InDesign, a solid eraser) to indicate that you’re creating a closed path.When the path is the size and shape you want, release the mouse button (but not the Alt or Option key). After the path closes, release the Alt or Option key.You don’t have to position the cursor over the starting point of the path in order to create a closed path; if you release the mouse button in some other location, the Pencil tool will close the shape by creating the shortest possible line back to the original point.it doesn't for me. after i start drawing and i hold the option key, it goes to drawing a straight line. i don't hold the key till after i start drawing lit says.
same thing with the connect two paths. holding the command key doesn't change the behavior of the pencil tool.i'm guessing there is no way of remapping the 'smooth tool' to option again? or was it moved to another hotkey?

I've made a pattern brush that I'm using to simulate a woods line for a boardgame map:
Shown above is the unstroked bounding box as well. To use this brush, I draw an outline of a woods mass with the pencil tool, then apply the brush and Expand Appearance. At that point I'm hoping the brush sections will join into one closed path so that I can fill it with a woodsy green, but instead the fill gets applied to each section of brush independently:
The join points seem fine - it's not like the two ends of the brush don't line up at all: EDIT - Actually, that's not just one point in the middle there - that's the ends of both paths lying almost on top of each other. It's possible to separate the two and then ctrl-J join them. Problem is, I want that single path automatically.
So how to get Illustrator to treat the resulting path as one closed path instead of a compound path?

I'm using Illustrator CC. When I draw an outline with either the pencil tool or the paintbrush tool, I can't fill it in with color, even though the path appears to be closed. The "fill" square has a red diagonal line through it and won't switch to a color.

There is a way inside Illustrator to send back or front the anchor points of a path?
In the image below was createad with Pen Tool starting from left to right but if i want to bring some of these crossing points back and forth from each other, is it possible?
Like in the middle one to send it back from the other behind it?

I'm having trouble making adjustments to my compound path/shape, as I'd like to outline the inside of the shape with a stroke - but this doesn't seem possible as the stroke always surrounds the outside too.
So: I've got a simple rectangle with white fill, with a rectangle-window hole cut out of it using the compound path action so you can see the layers beneath. Now I want to stroke the window hole, but NOT the outside of the entire rectangle. I'd be happy to split the shape up and tried various options like divide, edit in isolation mode, expand (button is greyed out), all the pathfinders - but none of them allow me to do this only to the inside part of the path.
How I can perform this action? I'm working in CS5 and CS6.

I'm trying to add a stroke that's aligned to the outside of my path. It appears to be offsetting the stroke *and* moving anchor points at the same time. It does the same kind of thing when I align the stroke to the inside. It is fine when i align the stroke to center. The one that is offset to the top-left is the align-inside one.

Using transform tool to rotate, often gradients do not rotate. In the example below only the "w" gradient did. Good news is the rotate tool works fine.
Appears this has something to do with compound paths, as this normally does not happen on a new single path. Releasing the compound also rotates the gradient unexpectedly.

I have made a curved path in Illustrator CS6, just a simple stroke (left in picture). Is there an easy way to round the corner of the end of it? Something like the image on the right? (I just tossed a circle over top to give an idea)

Is there any way to find a specific point on a path, that is not necessarily an anchor point?
What I'd like to be able to do is tell Illustrator "Give me the coordinates of the point that's exactly at half of this path's length" or "... exactly 25% ...". And if that's possible, can I somehow add an anchor point to that point, or cut the path at that point?

I'm wondering how it's possible to drag only one handle out of an anchor point. Sometimes I have a path and some anchor points have only one handle dragged out. Now I want to adjust the other handle _without_ changing the already positioned handle. Is this even possible?
The "convert anchor point tool" does allow me to drag out handles, but only both at a time. This always results in changing the already positioned handle's position.

Is it possible to find intersection poit of the anchor point and any point on path?
Like on a picture, there are an anchor poit from a line, which intersects arc path, and I need to find intersection poit on the arc (can be line) path. Thus I can do further processing for arc after intersection - change position, set color etc.
I suppose I need to divide that arc path and that will be the best way, but all I need for this moment extract point before intersection and after and process in our custom preview. Is there way to find this intersection?

I have had this problem since I started using patterns. Basically when I put a pattern on a path I want to then move it along that path so it starts where I want it to start, not neccessarily on the path's starting point.
There is an image of how it looks like
I created a simple pattern to show my issue. For example I want to move this pattern along this circle so it looks like this (triangle points up)
As you can see I rotated the whole circle to get the right outcome I need, but if it was just a regular path I would not be able to fix it this way.
Is there a way to do that? Something like moving text along a path.
I am using Illustrator CC.

So i've got a stroke in a circular path. I use the scissor tool and cut a segment of it out. Now, i want to move one of the end points up and have the anchor points after it follow the movement to keep the smooth line. I think Flash had a tool like this. It allowed you to manipulate one point that would affect the whole path depending on how extreme or what direction you went.

I know I can wrap text around an object with the properties docker, but I don't know how to wrap it inside a closed shape (not a box).
How can I put text inside a circle, for example? In other words, How to put text inside a curved container?

Once a path is closed, how do you break it open? And while I'm at it: I have a vector mask. I want to draw another vector shape and subtract it from this vector mask. How would I do this?

Is it possible to swap which side of a closed path - inside or
outside - masks a fill layer?
Let's say you draw a closed path with pen tool and then add a solid color fill layer which will be masked by the path so that the inside of the
path gets the color - what if you want the color on the outside instead,
how do you do it?

I really enjoy this new draw inside feature in Illustrator. But, I find that it does not always work. It seems to be grayed out sometimes. For example, I have drawn a shape with my Wacom tablet using a blush. I then converted it to a shape instead of keeping it a stroke by expanding it. But it will not allow me to now draw inside of it, even though it is a shape.

Is there any way to make vector text bear the characteristic of "closed path data"? Perhaps prior to, or after, applying the text in PSP? I am trying to import files from Corel PaintShop Photo Pro into MotionStudio 3D.
I am able to bring in vector objects created, but is there a way to make it so that vector text works also, by making vector text "closed"?

I've noticed that sometimes when I use an artistic media brush around a closed path, I can't change the brushstroke color without filling the path with that color; see the attached file for an example. I thought that was just unfortunately the way it was.But today I watched Jeff Harrison's video tutorial [URL]...about making a custom brush. He applies it to a closed path, and then, to my surprise, he changes the color and it just changes the color of the brushstroke.
I followed the tutorial, made the brush, applied it to a rounded rectangle, all fine. However, when I changed the color, the center of the rectangle filled with the color as well as changing the brush color, as it always has for me in the past. So what's wrong? Do I have some setting somewhere set to the wrong thing? (I don't have Fill Open Curves checked.)

I've have code to test if the insertion point is within a closed polygon. But prior to testing the insertion point I use ssget to trim the selection set initially..
(ssget "CW" Pnt_List (list (cons 0 "INSERT")(cons 2 BlockName)))
this requires that the whole Crossing Polygon is visible, so I do a zoom first. This requires time. Is there a way I can do this that does not require the zoom?
