I need to parse a tiff image and get the tie points (Lat/Long coords) to place on a map. Does anyone know how to do this using C#.NET?

Hi,
I am trying to use Python to do the following:
- read in an image in geoTIFF format
- extract the tags from the file
- do something interesting with the tags
I've read about the Python Imaging Library (PIL) which seems to do
what I need with TIFF files. I was wondering if anyone knows if this

Hi all--
I've succeeded in using the PIL (Python Imaging Library) to read a
simple GeoTIFF file and to extract data from the file's GeoTIFF key--
but I'd also like to write GeoTIFFs, and there doesn't appear to be a
one-step way of doing that.
I suspect, first, that -writing- a GeoTIFF file with PIL means poking
around in the PIL TIFF plugin file which I'm a little wary of doing.
Also, I don't see any clear description in the PIL...

I have a set of, say, 2000 points in the 8-dimensional simplex
S={(x_1,x_2,...,x_8),x_1+x_2+...+x_8=1, x's>=0}.
To help analyze that 8-dimensional set, I wish to project
the set of points onto each of the 'faces' {x_i+x_j+x_k=1}
for the 56 choices i,j,k, that is, i=1 to 6; j=i+1 to 7; k=j+1 to 8.
Finally, use gnuplot to load and plot each of the 56 files of 3-d points.
I have C code that will, for given i,j,k, find the projection...

Here is an example of the type of data from a file I will have:
Apple,4322,3435,4653,6543,4652
Banana,6934,5423,6753,6531
Carrot,3454,4534,3434,1111,9120,5453
Cheese,4411,5522,6622,6641
The first position is the info (the product) I want to retreive for the
corresponding code. Assuming that the codes are unique for each product
and all code data is on one line.

I am assuming that you know or are capable of looking up the functions I am to describe here and have some remedial understanding of C programming.
FYI
Although I have called this article “How to Parse a File in C++”, we are actually mostly lexing a file which is the breaking down of a stream in to its component parts, disregarding the syntax that stream contains. Parsing is actually including the syntax in order to make...

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...
