Hi,
I need to convert a 24-bit RGB TIFF image to an 8-bit RGB TIFF image.
I've tried using PIL and the convert() method - this allowed me to
convert to an 8-bit grayscale image, close but not exactly what I need
:(
From what I've read, it doesn't look like I can do what I need in PIL.
Does anyone know of another method ?

Hello,
I've been programming in ASP for a little while now and quite an
advanced user, but I have come across an unusual problem in which I
need assistance.
I have built my own image upload, I have two versions of the binary to
string conversion one fast, one slow because some servers use
chillisoft and therefore the append function in not accessible for a
disconnected recordset.

Hi all,
got a problem when converting a PNG to a JPG using the Image.Save(stream,
format) method.
When I save the original PNG to a file and open it, it's fine. I then save
it to a database, retrieve it and Save it as a JPG format and most of the
image is fine except a large black band at the bottom of the image.
What can i do?

Hi,
What is the better way to save image into a database ?
Just save the path into a field or save the image itself ?
I have 20 000 images (~ 10/12 Ko per image ) to save.

I get the following error in my code when I set Option Strict to On:
Option Strict On disallows implicit conversions from 'System.Object'

The blue error underline starts at "ResMan" and goes to the end of the

We're authoring a VS 2005 app that includes several EXE's and DLL's and also
uses a COM component (a customer requirement). The COM component provides a
graphic image to be used by the .NET app; the graphic is supplied as a
"StdPicture" (AKA, IPictureDisp).
How can I convert this to a .NET Image? A search of the object browser
shows:
protected static System.Drawing.Image GetPictureFromIPictureDisp(object

Hi all,
I need to convert a tif image, grabbed by a pixelink industrial
camera, to a text file (1024x768 elements) but I really don't know
how.
Surfing the net I found that there are a lot of methods to write a
tiff image but how can I understand which is the one used in mine?
Can you suggest me some example of code I can use to read the image?

Hello,
I'm working on an image processing project using the Python Imaging
Library along with numpy. Right now, I'm trying to build a speedy
script for converting whole images between the RGB and the HSV (a.k.a.
HSB) color spaces. Unfortunately, the code I've made so far runs
dreadfully slow with even moderate-sized images.
I'm under the impression that the crux of the problem is the fact that
PIL's point method operates on only one...

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...

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
