to anti-alias the printed appearance of a
low-resolution image.
11 Click OK.
Saving files in GIF format (Photoshop)
You can use the Save As command to save RGB,
indexed-color, grayscale, or Bitmap-mode image
directly in GIF format. When saving an RGB
image, Photoshop automatically displays the
Indexed Color dialog box, letting you choose
indexed-color conversion settings as the image is
saved to GIF.
Note: You can also save an image as one or more GIF
files using the Save for Web command (Photoshop)
or the Save Optimized command (ImageReady).
For more information on optimizing images,
see "Choosing a file format for optimization" on
page 317 and "Optimizing images" on page 320.
To save a file in GIF format:
1 Choose File > Save As, and choose
CompuServe GIF from the format list.
2 Specify a filename and location, select saving
options (as described in "Setting file saving
options (Photoshop)" on page 358), and
click Save.
For RGB images, the Indexed Color dialog box
3
appears. Specify conversion options as described
in "Conversion options for indexed-color images
(Photoshop)" in online Help and click OK.
4 Select a row order for the GIF file and click OK:
Normal to create an image that displays in a
•
browser only when it is fully downloaded.
Interlaced to create an image that displays as
•
low-resolution versions in a browser while the full
image file is downloading. Interlacing can make
downloading time seem shorter and assures
viewers that downloading is in progress. However,
interlacing also increases file size.
Saving files in JPEG format (Photoshop)
You can use the Save As command to save CMYK,
RGB, and grayscale images in JPEG format. Unlike
GIF format, JPEG retains color information in an
RGB image but compresses file size by selectively
discarding data.
Note: You can also save an image as one or more
JPEG files using the Save for Web command
(Photoshop) or the Save Optimized command
(ImageReady). For more information on optimizing
images, see "Choosing a file format for optimization"
on page 317 and "Optimizing images" on page 320.
To save a file in JPEG format:
1 Choose File > Save As, and choose JPEG from
the format list.
2 Specify a filename and location, select saving
options (as described in "Setting file saving
options (Photoshop)" on page 358), and click
Save.
If the image contains transparency, select a
3
Matte color to simulate the appearance of
background transparency. (See "Making trans-
parent and matted images" on page 339.)
