Hai,
I gotta decode a barcode from an image ( ppm, bmp, or jpg). I realize the
first milestone would be to recognize a barcode with in the image:
I took a small window (say 80X80 pixels) and if a barcode is present in
this window all pixels horizontally would have the same values. Well as you
can see this is not perfect. I'm right now working with PPM image.
and then to decode the barcode itself (which i've no clue how to do).

I have an asp.net application which loads a Crystal Reports
ReportDocument, passes in parameters for selecting data from the
report's database connection, renders the report for previewing on the
client then allows the user to print the report on a networked printer.
To avoid having to launch an external application on the client I use a
server-side print method. When I call ReportDocument.PrintToPrinter the
report comes out fine but the...

I am working on an online promotional deal for a client where I need to be
able to create a barcode that can be redeemed at checkout of one of their
branch stores. Has anyone worked with this before? It seems pretty
straitforward in terms of genrating the barcode dynamically from the numbers
I'll be given, but doesn't a barcode have to print at a particular size and
resolution in order to work? I was thinking of generating the barcode...

Hey all,
I've written a VB.Net app that creates picture badges complete with
barcodes. The problem is that the barcode quality is not good enough
to be read by scanners. I'm using the DRAWSTRING function to place
the barcode on the image, but no matter what graphics settings
(.InterpolationMode/.CompositingQuality etc.) I manipulate, the barcode
image remains poor quality. For exaple I'm using a solidbrush that
is black, but some of...

Does anyone know of any decent (open source or commercial) python
barcode recognition tools or libraries. I need to read barcodes from
pdfs or images, so it will involve some OCR algorithm. I also only
need to read the code 93 symbology, so it doesn't have to be very
fancy. The most important thing to me is that it outputs in some
python friendly way, or ideally that it is written in python. Any
tips would be great!

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:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
