QUESTION
I'm currently having a bit of trouble with CGAL's Polyline Simplification.
More specifically, for the following example, PS::simplify(ct, Cost(), Stop(0.2))
results in a self-intersecting polyline. In the image below, the blue polyline is the input polyline into PS::simplify()
while the green polyline is the resulting (output) polyline. The red arrow points to the self-intersection in the resulting polyline.
Further below, I have copied and pasted my code from 2 files simplify_test.cpp
and CMakeLists.txt
. With the required libraries installed, to run this example, you may place them in the same directory, cd
to that directory, and run the following in your terminal:
ANSWER
Answered 2021-Jun-09 at 00:32In the C++ code below, I essentially replaced Polyline
with Polygon_with_holes_2
. For all values of stop
, I now get topologically valid simplified polygons. I edited your output function. You can copy and paste the output from the new function print_coords_for_geogebra()
directly into Geogebra.
Here is the edited version of simplify_test.cpp
. You can compile it with the same CMakeLists.txt
that you included in your original post.

I want to flexibly hide/show the right border of some TDs inside a table, but the border color of the TDs could be different, e.g. red, black, or blue, so I cannot just do something like below:

Is there a possibility to toggleText() for each element of the array separately?
Right now, when clicked, the values are changed for every single element at the same time and I'd like to go over them one by one as they're clicked.

It is not recommended to loop to add eventListeners in JavaScript, jQuery or not.
QUESTION
I want to change the values inside my table based on what is selected in the select box.
The tds
have a data-value
. I want val2
and val3
to either be divided by the data-value
or leave it as is based on what I select.
This is my code:
...ANSWER
Answered 2021-May-26 at 23:31Probably went overboard, but I edited your function to calculate the data-value division (if 'division' was selected), then reverse it if you subsequently seleected 'original'. 'Original' still divides by 1 if you don't select division first, but after 'division' has been selected, if you select 'original' it will revert. To make this part easy, I added a data-orig
attribute to your td
setup. Like i said, overboard...
QUESTION
I'm setting up an input form project for my work, and for certain tables the user needs to be able to insert multiple data rows before moving onto the next form. I have the form set up in a table with input groups in the table cells like this:
...ANSWER
Answered 2021-May-26 at 18:52Here's how I might approach this. First, grab the initial table row on load to use as a clone template (before the user can enter any data). Then just append that to the table's body as needed using a click handler on the button, along with submitting an ajax request.
Note that I've moved your button outside the table. It wasn't valid there.
QUESTION
This is my code I am selecting two columns , and then I am taking the difference of correspoding cells and creating new column, and displaying it in a single table. I want to display it as a pop-up(modal box). Like on selecting two input checkboxes the resultant table should come as a form of popup and after closing it, i can again select any checkboxes and again a table should be formed and display as popup But when I am doing this way its is not coming as a pop and the same table is getting appended. Can anyone please help with this one?
...ANSWER
Answered 2021-May-26 at 02:59You are using the same table
variable for #main-table
and for the results table. However the results table
variable is only available inside buildTable()
, and when you use modalBody.append(table);
outside of that function, you are moving the #main-table
instead. So for your own sake, try avoid recycle variable names.
Also, you don't have to use getElementById
for the element you just created via createElement()
QUESTION
My problem with a website:
Although the data changes regularly, the structure of the data always remains the same. I try to transfer the content (only the last two columns with the headers: Aktenzeichen and Aufgehoben) to excel in 3 columns (ID-Number, Date, Time) by splitting the values of Aufgehoben in date and time.
My problem is that the values in "Bundesland" and "Amtsgericht" columns (even though I don't need those) have a different frequency of occurrence than the rest of the data and mess up all the trs and tds in the html-structure and so I don't understand how to use the selectors! Any ideas? THX.

QUESTION
I have a model named Layer.cs and it has a property named Geometry like:
...ANSWER
Answered 2021-May-12 at 11:28After a bunch of trials and errors, I founded a comprehensive solution to this.
Database and modelswhen we dealing with a GeoJson file, each feature can (or even should!) save in a separate NetTopologySuite.Geometries.Geometry type. (in other words, I changed the structure of my table from one stand-alone table to two tables with a parent child relationship)
SerializationIn fact, we don't need to serialize any things manually when are using NetTopologySuite.IO.GeoJSON4STJ. in our code, we only need to work with NetTopologySuite.Features.FeatureCollection and add NetTopologySuite.IO.Converters.GeoJsonConverterFactory to JSON converters when we add controllers. but there is also a trick here, at the registration time we should use NetTopologySuite.Geometries.GeometryFactoryEx instead of NetTopologySuite.Geometries.GeometryFactory (attention to the Ex word at the end). the reason for this is SQL server Require left-hand-rule (CCW) but GeoJson Required right-hand-rule (REFRENCE) so:

I ran this table in the W3 validator and it fails. I get this message "Error A table row was 6 columns wide and exceeded the column count established by the first row (2)".
...ANSWER
Answered 2021-May-10 at 21:58Each row (tr) has to have the same amount of cells (td). Except if you are using colspan, but then the sum of the spanned cells and the other (single) cells still have to be the same amount.
