Hi, Dear Brian Burkhalter:
Thank you so much for you kind reply.
May I ask for a simple code from you to save an ".jpg“ format image.
My code is something like:
BufferedImage bImage = doRender(width, height);
RenderedImage fImage = JAI.create("format", bImage,
DataBuffer.TYPE_BYTE);
JAI.create("filestore", fImage, filename + ".jpg", "jpeg",
null);
However, Eclipse notified that the 2nd line is deprecated and there
is a cross line on "create" in the 2nd line (in red).
What's more, even if the 2nd line is deprecated, I'm still able to
save an image in .jpg format. However, what has been saved can not
be previewed by many software, including "Windows Picture and Fax
Viewer", "Image Magic Display", "Windows Paint", etc. I can only
preview the image by using "QuickTime Picture Viewer". That's not
actually what I expected and I think the saved image should be able
to be previewed by all the popular softwares.
So, can you please help to give me your code when you tried to
save .jpg files? Thanks in advance.
Best Regards
JIA Pei

ImageIO has a quantization level, but if you want to use the other
features of the Sun encoder like horizontal/vertical subsampling, for
example, I think you're out of luck. Sorry.

Hi, Dear All:
I happened to notice there is some differences between SUN JDK and
OpenJDK.
In fact, I'm using "JPEGImageEncoder", which seems to be supported
well by
SUN JDK but not by OpenJDK. Especially, the function
"setJPEGEncodeParam".
So, I'm wondering if JAI+JAI ImageIO can replace the above
JPEGImageEncoder
? My purpose is just for .jpeg image saving.
