How can I remove "red lines" that become permanent to my map canvas while trying to digitize different shapes. The program just leaves the outline of what I'm trying to draw. It still remains even if I close all of the layers and empty everything. I've encountered this error numerous of times when creating circles, lines etc.

I'm using QGIS 2.18.15 and have somehow ended up with the following on my screen. I've deselected every layer and these green X's and red lines persist. I cannot "undo" to remove them.   What are they &amp; how do I get rid of them?   They may have originally been related to a duplicate node or something like that, but I have no idea what's going on.

How can I draw outlines around 3D models? I'm referring to something like the effects in a recent Pokemon game, which appear to have a single-pixel outline around them:

I have a raster that denotes certain landcover types.    How do I delete all of the pixels except for the ones I want?  I tried going through the symbology tab and while that deletes it for display it doesn't change the raster file itself, so if I were to delete and reload the file it would revert back.

I very recently started learning how to use Adobe Illustrator (CS6), and just now I noticed something strange. When I add a 1pt stroke to my shape, it gets slightly distorted. This distortion does not disappear if I remove the stroke. (But only if I remove the stroke by setting its weight to 0. Using CTRL+Z does return the shape to its former state.)  After adding and removing the stroke a few times, the difference becomes quite noticable:   Am I doing something wrong? Is it a bug? I can't imagine this being the expected behaviour.  EDIT: I think I figured it out. Appearantly, turning 'Align to pixel grid' off doesn't affect previous shapes. If I turn it off and then recreate my shape from scratch, the problem is fixed.   However, I was wondering if their is a way to disable the effect for existing shapes. In other words, can I 'fix' the shapes I created while 'Align to pixel grid' was still on?

I have some map files consisting of 'polylines' (each line is just a list of vertices) representing tunnels, and I want to try and find the tunnel 'center line' (shown, roughly, in red below).    I've had some success in the past using  but I'd like to avoid that method as it does not (in general) allow for easy/frequent modification of my map data.  Any ideas on how I might be able to do this?  I'm working in fairly raw C++.

How do I remove them?    They don't appear when using flat shading.    Nothing in the scene can cause this.

I was just getting back into using Blender a few days ago and I must have hit a couple of buttons. But now I cannot get these dashed lines to go away. Does anybody know how I can make them go away?

Building on the answer  by wrtlprnft, I have the following code     \documentclass[tikz,margin=1cm]{standalone}    \usetikzlibrary{decorations.markings}    \begin{document}    \begin{tikzpicture}         \tikzstyle{arrowed double line}=[             dashed, double distance between line centers=3pt,             postaction=decorate,             decoration={                 markings,                 mark=between positions 10pt and -10pt step 20pt with {                     \arrow[thin,yshift= 1.5pt,xshift=.8pt]{&gt;}                     \arrow[thin,yshift=-1.5pt,xshift=.8pt]{&lt;}                 },             },         ]         \draw[arrowed double line] (0,0) --  (1,2);     \end{tikzpicture} \end{document}   which produces this:    I am unhappy with the faint transverse lines between the dashes. I don't even know why tikz decides to draw them.  Is there a way to get rid of them?  Thanks in advance to all replies.  PS the same thing occurs at the caps of double solid lines

Is this intended behavior (with plain XeTeX):  \input tikz \tikz\draw[dashed] node {$3T\over4$}; \bye   It renders as: !?  The fraction line is dashed, too! Is this intentional? Is there something I can do to change that? I know I can separate the fraction into its own node, but other than that?

I would like to have my object transparent, with a color only on the edges, would someone know how to do this? I am starting with the nodes, if anyone can help with some guidelines I would really appreciate ;-)  EDIT:  I was looking for something like the hand in Kinectimals :    Thanks

I'm an Illustrator beginner, and I have just made pie chart. I removed the borders but I still end up with a 1 pixel wide border between the pieces of the pie whenever I export to PDF or AI. Please see the attached image (zoomed to make it easier to spot it).    The question is: How do I get rid of it?

I want to give these line segments a continuous cylinder shape, like a Spaghetti noodle. My aim is to make this path visible in render mode. At the moment you are not able to see it in render mode because it has zero thickness.  I already converted them into a Bezier curve and played around with the Bezier Circle. The result were a lot of cylinders behind each other with a lot of gaps between them because the whole line has edges as you can see on the picture.  I also tried to solve the problem with a Skin-Modifier, but this didn't give me a good solution either. Maybe I should combine it with another Modifier.  So I was wondering if it's even possible to convert an 3D edged path into a curve path with a cylinder shape.  I would be very glad if someone could tell me how I get a good solution.  Thank you very much!

When I try to draw a line on an image using Preview's annotation tools, it doesn't remain as I drew it but instead the line is drawn linear. How can I set it to be preset as nonlinear?  So looking to the images, I don't want it to be set like this:    Instead I want it to be preset in this way, instead of clicking the actual function everytime to make it nonlinear.

I have some text. I changed it to outline. Drew a rectangle on it. Selected all and then pathfinder->minus front. I got a weird result. How can get my desired effect in this way?

I'm trying to create a transparent Polygon in ArcMap; however, it's never transparent.  Here's the code I have.   // Create polygon IPolygon polygon = new PolygonClass(); // create &amp; add points,......  // Create lineSymbol ISimpleLineSymbol lineSymbol = new SimpleLineSymbolClass(); // set color &amp; style,....  // Create fillSymbol ISimpleFillSymbol fillSymbol = new SimpleFillSymbolClass(); fillSymbol.Outline = lineSymbol; fillSymbol.Color = //set to color red//; fillSymbol.Color.Transparent = 0; fillSymbol.Style = esriSimpleFillStyle.esriSFSSolid;  // Draw Shape myMap.DrawShape(polygon, fillSymbol);   RESULT ==> A solid red polygon is drawn.  The Transparent setting is ignored.  Thoughts?

I would like to show on my map only the reddish pixels of my raster layer.  Said in another way: I would like to transform my white background into transparent background so I can see my other features.  I have the feeling this is possible using the custom transparence tab in the layer property.

I'm trying to delete those ugly lines visible in the cylindrical shape of the lens. What is causing them is the added edge loops I made for the protruding detail with the switch. The problem is that if I delete those edges, it'll look even worse because of the n-gons. Any ideas?
