JPEG format
Joint Photographic Experts Group (JPEG) format
is commonly used to save photographs and other
continuous-tone images. JPEG format retains all
color information in an image but compresses file
size by selectively discarding data. You can choose
what level of compression you want when you save
a JPEG file. A higher level of compression results in
lower image quality and a smaller file size; a lower
level of compression results in better image quality
and a larger file size. In most cases, the Maximum
quality option produces a result indistinguishable
from the original.
JPEG is one of the standard formats for displaying
images over the World Wide Web and other online
services. You can save an image as a JPEG file. (See
"Optimizing images" on page 230.)
To save a file in JPEG format:
1 Choose File > Save As, and choose JPEG from
the format list.
Specify a filename and location, select saving
2
options (as described in "Saving images" on
page 246), and click Save, which opens the JPEG
Options dialog box.

3 If the image contains transparency, select a
Matte color to simulate the appearance of
background transparency. (See "Making trans-
parent and matted images" on page 233.)
4 Do one of the following to specify the
image quality:
• Choose an option from the Quality menu.
• Drag the Quality pop-up slider.
Enter a value between 1 and 12 in the Quality
•
text box.
Select a format option:
5
Baseline ("Standard") to use a format that is
•
recognizable to most Web browsers.
Baseline Optimized to optimize the color quality
•
of the image and produce a slightly smaller file
size. This option is not supported by all Web
browsers.
Progressive to create an image that displays
•
gradually as it is downloaded to a Web browser—
in a series of scans (you specify how many)
showing increasingly detailed versions of the
entire image. Progressive JPEG images files are
slightly larger in size, require more RAM for
viewing, and are not supported by all applications
and Web browsers.
6 To view the estimated download time of the
image, select a modem speed from the Size pop-up
menu. (The Size preview is only available when
Preview is selected.)
Note: If you find that a Java application cannot read
your JPEG file (in any color mode), try saving the file
without a thumbnail preview.
Click OK.
