Good evening.
I want to read a .jpeg into a BufferedImage with anImageReader.read(0,
param) that I would then like to reduce (make a thumbnail more or less) and
save as another file with anImageWriter.write(aBufferedImage).
My (theoretical) options seem to be to reduce it while I'm reading it,
reduce it from the BufferedImage, or reduce it while I'm writing it.
BufferedImage is of course a subtype of Image and Image has a

I have a fairly simple Python program that uses Image and ImageDraw to
create poll results on the fly.
Because PIL only supports 256 colors for GIF and BMPs are huge (in
comparison)... I have opted to create JPEGs.
I have installed JPEG-6b and have checked to see that all of the libraries
are in the correct, expected places. But, I am still getting the following
error.

Hi all,
I've got a picturebox on a form, and a save button. When I go to save,
the app craps out with the following error:

Hi everyone,
I'm trying to write up a simple image stamper application that stamps the
Exif date information from the jpegs that I've taken from my digital
camera and saves the new file with the date stamped on the lower right
part of the picture. (I'm not an advanced programmer so my code may not
be 100% efficient - sorry, I'm still learning)
Everything works fine until the saving part. I've been able to read the
file into a...

Hello,
I am a .NET programmer and I have a JPEG image file (from digital
camera) of about 109 KB's in size, when I open it and save it
(without making any alterations at all, just going to File --> Save) in
MS Photo Editor, the file is automatically shrunk in size to 81 KB's.
When doing the same thing in MS Paint, the file is shrunk to 54 KB's.
The file has the same number of pixels after both saves (as expected).
My question follows...

I want to get the R, G and B components as integers (0-255). I use this:
Rectangle area = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
BufferedImage bufferedImage = r.createScreenCapture(area);
int pixel = bufferedImage.getRGB(x,y);
But it returns some crazy 1 value of -65536 or something like that. How do I convert it to three individual integers R,G and B?

I'm trying to save a BufferedImage as a .tiff.
The following:
ImageIO.write(bufferedImg, "TIFF", new File("file.tiff"));
is returning false.
Do I need to use JAI?
I'm just trying to use the easiest way to save a .tiff.
Thanks.

I have been using something like:

Hey everyone,
I'm working on a program based on steganography. For this, i need to access the individual pixels and perform my manipulations. FYI, I do not have the JAI library available with me and I have to make do with awt, imageIO and image. I'm having no issues in loading an image but when i thought I would test things and just save the same image without manipulation I was surprised. After copying the pixels from the image into an int...

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,...
