I need to create image files (eg bmp or jpeg) of xy scatter graphs
(i.e., graphs in which markers denote individual points; the markers
need to be small polygons of various sizes, shapes, colors, shadings,
etc. and there are thousands on them on each graph). Have been using
MS Excel, but its limitations are unbelievable (only whole number
sizes, no way around a 56 color palette, only low quality jpeg files
so that when I publish the...

Hi all, I've written the following code to retrieve the file format of an
image file:
Dim objImageFormat As ImageFormat
objImageFormat = Me.SourceImage.RawFormat
If objImageFormat.Equals(Imaging.ImageFormat.Bmp) Then
Me.ImageFormat = "BMP"

I find Bitmap.Save works for WMF files but Bitmap.FromFile does not.
If I use FromFile on a WMF file that came with VS I get an exception.
If I use it on a WMF file created with Bitmap.Save I don't get an exception
but it appears the Bitmap is blank.
Can anyone share some knowledge on this?

Hi group, I've got a question about the size of a saved bitmap.
What I need to do is open a bitmap if it needs resizing, resize and save it.
This isn't a problem, but the problem I have is that the original image has
got an 8 bit indexed pixelformat,
but you can't create a graphics object for this pixelformat so my bitmap
uses the default pixelformat:
Format32bppArgb, but this ofcourse result in a much larger file size (420kB
instead of...

I am pleased to announced that GDCM is now supporting yet another
target language: C#.
You can now write code in C# and use the GDCM library (C++), thanks to
the use of SWIG for providing the wrapping layer.
Grassroots DiCoM is a C++ library for DICOM medical files. It is
automatically wrapped to python/C#/Java (using swig). It supports

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...
