ADOBE PHOTOSHOP 6.0 361 User Guide 10 Select Image Interpolation if you want 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. 3 For RGB images, the Indexed Color dialog box 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. 3 If the image contains transparency, select a Matte color to simulate the appearance of background transparency. (See "Making transparent and matted images" on page 339.)
