library for querying virtual polygon over raster spatial data
in my c++ application, after calculating my polygon
i wish to define it (simple 4 sided polygon with floats or line parameters)
and use this to query a b/w image in memory,
i want to get the pixel counts, full, hopefully partial, perhaps specific to
a side, data to calculate area ect, can someone help point me to a library

im gone for a long weekend so plenty of time for anyone to answer.
if i have 4 points representing a polygon and each point is represented by an x and a y coordinate, is there an easy (or slightly less painfull) way to decide whether or not a point (a,b) lays within that polygon?
please note that this polygon DOES NOT take the shape of a square and has NO right angles and all side lengths are somewhat random.
the application:
say i...

Hi,
Is anyone know that how to get the x and y points inside the polygon using C++ program?
I have the given polygon data to draw the polygon, but i don't know how to get all the points inside the polygon.
Eg. Let's say we have 5 points to draw a polygon.

Hi All,
I m a new member here.I am now writing a program that render Vertex Normals.I m now trying to implement a data structure that will best suit computing vertex normals.For that computation , my data structure should have accessed to the faces adjacent to each vertices.
first i read all vertices ,and faces from .m file into a structure.And stored in vectors.
vector<Vertex> vertices;
vector<Face> faces;
Then i render that model.No...

In several locations in the MSDN Mappoint Web Service SDK it says:
"Creating Polygons
There are several ways you can create and prepare polygon data for upload to
the Customer Service Site:
1. You can convert existing polygon data that you have created in other
applications by using the polygon conversion tool.
2. You can manually create an XML file that contains the polygon data."
But the only resource I can find is the creation of...

I have a function which creates a polygon of blue color. I call this function inside a loop of 128 iterations. For every iteration, i change the value of x and y so that my polygon is rendered on new location. This goes fine and i get 128 new polygons on my image after running the script. But if change the number to 129, the 129th polygon is transparent or what i cannot guess.It just does not display or render at all. Is this a bug or some...

Hello,
I am having a problem using intersects method of a class I made that extends Polygon. Basically, I am trying to write code that allows the user to drag these polygons. I create a 1x1 rectangle on a mouse press and look through an array to see if the rectangle intersects the polygon. If it does, then I call the polygon's move class, passing the x and y coordinates while the user is dragging. Problem is that it works the first time,...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
