There's a line in mentioned picture which has a dot at both endpoints.
Referring to the issue https://github.com/Mapsui/Mapsui/issues/956 , it only works for point feature. However if we draw shapes like line, polygons, these dots appear on end points of vertices/lines and are not removed by using Layer.style= null. Source code is used from the following branch
https://github.com/Mapsui/Mapsui/tree/master/Samples/Mapsui.Samples.Wpf.Editing/Editing
The code for this line is "if else" in the method Addvertex present in Editmanager.csClick for view the problem in screenshot
In the editing sample those dots were added on purpose because they can be dragged and added and deleted. I don't know by heart which style layer this is and do not have to code at hand. You should be able to find it if you search for Style or Styles in the Mapsui.Samples.Wpf.Editing project.

so I have a drawing program and I need to implement a "broken line", it is an SVG line with two another lines in the middle of this line, these two line needs to cross perpendicularly to the principal line, maybe this picture can help me to explain the problem:
This line can be drawn in any angle that the user choose
I don't really understand svg's so I'm having a lot of trouble implementing this.
Thank you
So I discovered one way to implement that using polylines and calculating the middle of the source and target coordinates, so when it changes I change the middle point too. After that, I created a marker-mid with the double lines.
I need to translate PSD file into HTML/CSS/JS...
Here is this project:
https://s15.postimg.org/s421pj5mj/PSD.jpg
https://s24.postimg.org/8xq87z3v9/PSD_2.jpg
QUESTION What are those 1.vertical and 2.horizontal sky-blue lines and how are they supposed to help me as for somebody who translates this PSD into HTML/CSS/JS ? Don't they seem a bit chaotic?
Despite being blue in your example, these are called "Redlines". The lines are meant to help you see the alignment, sizing, and spacing of elements.
For example, there is one center line down the very middle. You can use that to see that the "Creative Digital Solutons" text is centered, as is the the "Personal Services" text, "Responsive web" section, and "Latest project" section.
You can also see that at the very bottom of the second image, certain pieces of text in each column should line up with certain pieces in other columns.
Usually you will find a particular element or group of elements like this:
With the red lines I added you can see that the icons should all be the same width, and the left side of the icons should align with the left side of "Latest Posts".
Sometimes these redlines contain specific measurements (font: 14pt, margin: 10px, etc.), but this one doesn't, so you just have to use the lines to help you visualize
Yes it is chaotic, but that's how it goes sometimes
what I want to do is to trim some polylines that are saved as VLA-OBJECTS, there is no problem on converting them into Entities, but what I graphically want is to trim my Image in the following way:
So as you can see I want to trim everything of the blue lines outside the red circles on the corners and I want to it automatically without selecting anything. For this purpose, I have stored the circle as a VLA-OBJECT, The blue polylines as independent VLA-OBJECTS, the centers of the circles, in fact everything on the first image is stored on memory as a VLA-OBJECT. So I was wondering if you can suggest any lisp routine to do it automatically?. I was thinking on using the Break command or the Extend command but I can not find a real solution. Many thanks in advance.
I have no time enought to prepare working sample code, but I may show You the way. I would try to make it in this way:
You can find intersections of circles and lines.
( vlax-invoke-method circle 'IntersectWith BlueLine acExtendNone )
break each blue line by this
(foreach line BlueLines
(command "_break" line pt pt ) ; where pt is point returned by IntersectWith
)
and the last step is to check if all entities created by _break are inside or outside circles.
You don't have easy access to entities created by _break. to get them, You may use (entlast) before command _break. and (entnext) after that .
Has anyone figured out a way to dynamically mutate text on the screen without triggering a render?
A large part of my screen utilizes setNativeProps for moving parts, meaning that the animations become lagged despite using shouldComponentUpdate. I would like to use the Text tag instead of the TextInput tag workaround suggested in this post for stylistic reasons.
Best case scenario is a workaround that involves setNaiveProps as it would follow the pattern of the rest of the screen; however, I currently plan to render all the numbers 0-9 on the screen an move them into place at the moment, so any help would be greatly appreciated!
As it turns out, you can actually format TextInputs the same exact way as Text elements (from what I have tested). For placing text horizontally, you have to set the width (something I had trouble with before). For those still interested in the original question however, you can nest TextInputs inside of a Text Element (one per text element because there is no justification and it automatically places them in a row). Styling applied to the Text Element will apply to the TextInput.
I'm using LaTeX and I would like to have vertical rule along left side of page, topmargin to bottommargin, 0.5in from the left edge of the page. I want this on every page, so I assume that means it must somehow be tied to the header or the footer?
I've made no progress at all, so I need help with (1) making the full-length rule itself and (2) making it happen automatically on every page of the document.
Can someone tell me how to do that?
I got a working answer to my question on the Latex Community forum: http://www.latex-community.org/forum/viewtopic.php?f=5&t=9072&p=34877#p34877
The answer I got uses the 'Background' package and this code:
\documentclass{article}
\usepackage{background}
\usepackage{lipsum}% just to generate filler text for the example
\SetBgScale{1}
\SetBgAngle{0}
\SetBgColor{black}
\SetBgContents{\rule{.4pt}{\paperheight}}
\SetBgHshift{-9cm}
\begin{document}
\lipsum[1-90]
\end{document}
Works great and was easy to adjust to put one vrule in left margin area and one in the right margin area.
There could be a LaTeX package to do this for you, but I'm more of a TeX person, so I tried to come up with a TeX solution (not always the best idea to mix plain TeX with LaTeX but I think I have it working).
Try this. Box 255 is the box register that TeX places the page contents into before the page is output. What I've done is taken the existing output routine, and changed it to insert into box 255: a 0-height, 0-width infinitely shrinkable-but-overflowing set of boxes containing a rule that is the height of the page, 0.4pt thick and with any luck, half an inch away into the left. The existing contents of box 255 is then added after this rule. Then I call the previous output routine which outputs the page (which now includes a rule), and also the headers and footers.
\newtoks\oldoutput
\oldoutput=\expandafter{\the\output}%
\output{%
\setbox255\vbox to 0pt{%
\hbox to 0pt{%
\vsize\ht255%
\vbox to \ht255{%
\vss
\hbox to -0.5in{%
\hss
\vrule height \ht255 width 0.4pt%
}%
}\hss
}\vss
\box255%
}%
\the\oldoutput
}%
Put it before your \begin{document} command. This might not solve your problem completely, but hopefully it should get you started. Here's a great page for learning about TeX primitives and built-in things.
Have a look at the eso-pic package. From memory, what you want would look like this:
\AddToShipoutPicture{%
\setlength\unitlength{1in}%
\AtPageUpperLeft{%
\put(0.5,\topmargin){\vrule width .5pt height \textheight}%
}%
}
It's not clear in your question if you want the line to span the text area or the whole paper height. Depending on the case, you have to replace \topmargin and \textheight by the correct values, either 0pt or whatever your top margin is, or by \paperheight. See the geometry package if you don't already use it for how to control those dimensions.
