That's what i'm doing with my app as well.
And i have the same issue. As soon as your re-read a JPEG and save it
again (modified or not), you will get loss of quality. There is no
other way around it.
In my app, i don't save over the original image. I do a 'save-as',
more or less. At least the or
My application reads existing images from the mobile, and allows the
user to edit it and save it, if the image is in a jpeg format there is
a loss in quality when the image is edited and saved. Is there any
other way to open a jpeg image edit it and save it back?
Also i have noted one more thing
If you write a JPG, information is written with a loss. Always. Even
with quality=100, some loss will occur. If you do this repeatedly,
losses in image-data will compound.
Why not use the PNG format? Why do you need to write a JPG?

This is what i am doing can u please guide me as to what should be
corrected here,
On opening the file,
mBitmap = BitmapFactory.decodeStream(concontentresolver.openInputStream
(uri));
//to create a mutable bitmap out of it
mBitmap = Bitmap.createScaledBitmap(mBitmap,mBitmap.getwidth
(),mBitmap.g
Bitmap bmToSave = ... // the bitmap you want to save
int height = ... // height of bitmap
int width = ... // width of bitmap
int[] bmData = new int[TMP_BUFFER_SIZE]; // holds the ARGB data for
pixels of bmToSave
int heightChunk = ... // number of pixel-rows of bmToSave that will
fit into the buf
I am trying to write the contents of the bitmap without doing a
compress on it for a format, as I am facing somme problems in quality
while formatting.
I am using thte below code but its not working,
ByteBuffer bf = ByteBuffer.allocate(IMAGE_WIDTH*IMAGE_HEIGHT*4);
mBitmap.copyPixelsToBuffer(bf)
I'm writing an app that needs to save a color-corrected full-sized (6
megapixels == 12MByte) to a file (since it can't be held in memory
next to the original non-color-corrected bitmap):
'Original Bitmap' + 'ColorMatrix' --> 'Color-Corrected Bitmap in a
file'
I use getPixels to get an integer-a

A quick scan of Go
Hi Guys,
Im still not able to figure out the problem.
When i try to use the Bitmaps compress method for PNG formats there
doesnt seems to be any problem.
But for JPEG format there is a sever loss of quality even if i give
the quality as 100.
Any inputs please.
