polygon | Polygon Connector Project | Dataset library

• your sample data is not really usable for doing what you describe. Have used Northern Ireland geometry, population and COVID cases to demonstrate
• used dissolve() as you describe, have not bothered with fact some of the attributes cannot be summed (long and lat)
• simpler to see through visualisation, so have provided plots as each stage
• updated to use pandas cumsum() functionality to sub-divide regions for each time population exceeds 300K
• this dissolves C into 3 areas and E into 2 areas

So I use another library to solve this problem: OpenCV-python

We got have also the detection of segments( which are not disjoint) but with a hierarchy with the function findContours. The hierarchy is useful since the function detects different polygons. This implies no problems of connections we could have with the other method like explain in the post

My idea is to do following algoritm:

1. Loop all circles from highest sortorder to lowest. This simplifies generation of overlapping, since a polygon cannot be overlapped by one in lower sort order
2. Keep track of all previous polygons by generating a "mega polygon" which is a union of all previous. This simplifies overlapping of "lower" sorted polygons.
3. The current polygon will be a difference of the circle and the "mega polygon", ie, rest of the circle that isn't overlapping.

Now for the code, i firstly create some test data in a #t-table, and then make a recursive cte to generate the polygons. You can also use a while loop or cursor if that's simpler

apparently this was caused by a null pointer. fixed it with an if else statement.

I'm pretty sure the problem is this call:

Yes you can imitate the behavior of a group of RadioButton controls in a container. Just find the controls of the same type in the Parent.Controls collection and uncheck them when the current instance is checked.

Example

Add this method to MyToggleButton class.

The mask simply isn't big enough to cover the shape. You've not set any height/width for it so you'll get the defaults of 120%. That's not enough in this case for the width.

Increasing the viewBox width corrects things as the mask width is a percentage of that viewBox width so you're indirectly increasing the mask width.

You have constructed something like

The problem is - the code is rendering the complete path - start-to-end each time and start is same for all animations.

The idea for loaders is - start point has to change after each animation - something like -

1. Start at angle 0
2. Go up to angle 45 /// or 60 whatever you want this to be
3. Change start angle to next logical step - say 30
4. Then render up to 75 /// or 90 depending on what you chose previously

In this arrangement, you have to keep drawing a certain portion of the shape by changing start point continuously.

In practice, achieving a smooth transition between different start point values may prove out to be difficult than it seems. You can find an example here - https://github.com/SVProgressHUD/SVProgressHUD/blob/master/SVProgressHUD/SVIndefiniteAnimatedView.m#L48-L102

UPDATE

The link I shared above has all the hints in it. This library uses an image as a mask and then rotate that continuously. Mask shape can be anything you like - you already have code for that.

You just need to create an image that's appropriate for your animation. See what their asset looks like

and AFTER masking what their animation looks like -
