I'm having problems with converting a byte array to an image object~
My byte array is an picture in VB6 StdPicture format. I've used propertybag
to convert the picture into base64Array format in XML, and embedded
the array as some child element in an xml file, i.e.:
<Mask>bHQAAH4AAABCTX4AAAAAAAAAPgAAACgAAAAQAAAAEAAAAAEAAQAAAAAAQAAAAAAAAAAAAA
AA AAAAAAAAAAAAAAAA////AP//AAD//wAA//8AAP//AAD/7wAA//cAALtzAABVeQAAVUAAAFVA...

Hello,
I am trying to convert a jpeg image stored in a PictureBox to a byte array
in order to later save it to a database, but I get this error : "Generic
Error in GDI+".
The source code is the following (when clicking in a button):
MemoryStream ms = new MemoryStream();
pictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); //

Hello,
I am creating an RTF document server side for a report.
However I am having problems converting images into the required RTF
format.
I am converting the image into a string (binary) and including the
image syntax as per the RTF Specification, however the image is not
appearing when I view the document in Word or WordPad.

I need to convert this buffer to a Bitmap of Format32bppArgb and to a Bitmap
of Format24bppRgb.
Can anybody tell how to do it?

I'm trying to convert this simple string into image:

I am interested in converting sets of 4 bytes to floats in C++. I have
a library that reads image data and returns the data as an array of
unsigned chars. The image data is stored as 4-byte floats. How can I
convert the sets of 4 bytes to floats?
Thanks,
Greg Book

Hi
i want to save the read the image file and show it on a image control of
a mobile webform .But the mobile control does not support html images

i have the image available in a datarow which is read from db. As
control only has the imageurl property ,i need to save the read image to
an image image file and then assign it to the control .

Hello all,
I am having a hard time seeing what I am doing wrong with a program I
am having to write that converts pbm monochrome images into a similar
pgm file. The problem I am having is understanding how to properly
convert the bit/pixel in pbm to byte/pixel in pgm. My program is very
straight forward conceptually open files, read header, read binary
data, convert to p5 in loop and then write file out. My for loop is
where I am...

Hello,
I am using a library which returns a byte containing RAW data, ie all
pixels' color values coded in a byte array without header. I would like to
save those data into a JPEG file so I tried to use the MetaFile class.
byte data;
(...) // Creating the RAW image through the DLL call.
MemoryStream memoryStream = new MemoryStream(data);

I need to make the string "myFile" into a byte and then put it in the database as a file/image, where later it needs to be pulled out and back into a string from the byte. I'm really having trouble gettting it back into a string afterwards, but I don't even know if the data is being put in the database with correct values. Any suggestions or pointers would be much appreciated. Thanks!
(I posted the main section I'm having trouble with, but I...

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...

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,...

Dear forum friends,
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.
