Adobe Photoshop Help Using Help | Contents | Index Saving and Exporting Images Back 452 Saving files in TIFF format TIFF is a flexible bitmap image format supported by virtually all paint, image-editing, and page-layout applications. To save a file in TIFF format (Photoshop): 1 Save the artwork, and choose TIFF from the Format menu. (See "Saving files" on page 446.) 2 In the TIFF Options dialog box, select the options you want, and click OK. Image Compression Specifies a method for compressing the composite image data. (See "About file compression" on page 453.) Byte Order Photoshop and most recent applications can read files using either byte order. However, if you don't know what kind of program the file may be opened in, select the platform on which the file will be read. Save Image Pyramid Preserves multiresolution information. Photoshop does not provide options for opening multiresolution files; the image opens at the highest resolution within the file. However, Adobe InDesign and some image servers provide support for opening multiresolution formats. Save Transparency Preserves transparency as an additional alpha channel when the file is opened in another application. (Transparency is always preserved when the file is reopened in Photoshop or ImageReady.) Layer Compression Specifies a method for compressing data for pixels in layers (as opposed to composite data). Many applications cannot read layer data and will skip over it when opening a TIFF file. Photoshop, however, can read layer data in TIFF files. Although files that include layer data are larger than those that don't, saving layer data alleviates the need to save and manage a separate PSD file to hold the layer data. For more information on RLE and ZIP compression, see "About file compression" on page 453. Choose Discard Layers and Save a Copy to flatten the image. Note: To have Photoshop prompt you before saving an image with multiple layers, select Ask Before Saving Layered TIFF Files in the File Handling section of the Preferences dialog box. To save a file in TIFF format (ImageReady): 1 Choose File > Export Original, and choose TIFF from the format list. 2 Specify a filename and location, and click Save. 3 Select a compression method, and click OK. (See "About file compression" on page 453.) Exporting images in ZoomView format (Photoshop) ZoomView is a format for delivering high-resolution images over the Web. With the Viewpoint Media Player, users can zoom into or out of an image and pan the image to see its various parts. When you export an image in ZoomView format, Photoshop creates the following files: • An MTX file that defines the image to be displayed. • An HTML file that loads the Viewpoint Media Player and points to the MTX file.
