Сьюзан отпрянула. О Боже. Значит, она слышала звук выстрела Хейла, а не коммандера. Как в тумане она приблизилась к бездыханному телу. Очевидно, Хейл сумел высвободиться.

Graphics file formats differ in the way they represent image data as pixels or vectors , and support different compression techniques and Photoshop features.
To preserve all Photoshop features layers, effects, masks, and so on , save a copy of your image in Photoshop format PSD. The standard bit depth for images is 8 bits per channel. To achieve greater dynamic range with or bit images, use the following formats:. Many file formats use compression to reduce the file size of bitmap images. Lossless techniques compress the file without removing image detail or color information; lossy techniques remove detail.
The following are commonly used compression techniques:. Most useful for images with large areas of single color. Recommended for continuous-tone images, such as photographs. JPEG uses lossy compression. For the best printed results, choose maximum-quality compression. A family of lossless compression techniques for black-and-white images, supported by the PDF and PostScript language file formats. For more information, see Help for the specific Adobe applications. When saving a PSD, you can set a preference to maximize file compatibility.
This saves a composite version of a layered image in the file so it can be read by other applications, including previous versions of Photoshop. It also maintains the appearance of the document, just in case future versions of Photoshop change the behavior of some features.
Including the composite also makes the image much faster to load and use in applications other than Photoshop, and may sometimes be required to make the image readable in other applications. Mac OS You can use this format to open an image in Photoshop 2.
Saving in Photoshop 2. You can use DCS 2. Encapsulated PostScript EPS language file format can contain both vector and bitmap graphics and is supported by virtually all graphics, illustration, and page-layout programs. EPS format is used to transfer PostScript artwork between applications. When you open an EPS file containing vector graphics, Photoshop rasterizes the image, converting the vector graphics to pixels.
EPS does support clipping paths. You use DCS 2. You can edit and use an opened preview image just as any other low-resolution file. The current version of Photoshop includes rasterization features for opening files that include vector data. The Photoshop Raw format is a flexible file format for transferring images between applications and computer platforms.
Documents saved in the Photoshop Raw format can be of any pixel or file size, but they cannot contain layers. The Photoshop Raw format consists of a stream of bytes describing the color information in the image. Photoshop designates the number of channels needed to describe the image, plus any additional channels in the image. The file creator is also generally a four-character ID. The Header parameter specifies how many bytes of information appear in the file before actual image information begins.
This value determines the number of zeroes inserted at the beginning of the file as placeholders. You can enter a header when you open the file in Raw format. You can also save the file without a header and then use a file-editing program, such as HEdit Windows or Norton Utilities Mac OS , to replace the zeroes with header information.
You can save the image in an interleaved or non-interleaved format. If you choose interleaved, the color values red, green, and blue, for example are stored sequentially. Your choice depends on requirements of the application that will open the file. A Photoshop Raw image is not in the same file format as a camera raw image file from a digital camera. Digital Negative DNG is a file format that contains the raw image data from a digital camera and metadata that defines what the data means. BMP is a standard Windows image format on Windows-compatible computers.
BMP images are normally written bottom to top; however, you can select the Flip Row Order option to write them from top to bottom. You can also select an alternate encoding method by clicking Advanced Modes. Using the Cineon format, you can output back to film with no loss of image quality.
The format is used in the Cineon Digital Film System, which transfers images originated on film to the Cineon format and back to film. DICOM files contain both image data and headers, which store information about the patient and the medical image.
GIF format preserves transparency in indexed-color images; however, it does not support alpha channels. Use raw files from Canon cameras for best results. IFF Interchange File Format is a general-purpose data storage format that can associate and store multiple types of data.
IFF is portable and has extensions that support still-picture, sound, music, video, and textual data. A JPEG image is automatically decompressed when opened. A higher level of compression results in lower image quality, and a lower level of compression results in better image quality. In most cases, the Maximum quality option produces a result indistinguishable from the original. All Photoshop features, such as layers, effects, and filters, are supported.
With documents larger than 30, pixels in width or height, some plug-in filters are unavailable. Most other applications and older versions of Photoshop cannot support documents with file sizes larger than 2 GB.
The film format has high color fidelity and a dynamic range suitable for use in motion picture production. Based on the PostScript imaging model, PDF files accurately display and preserve fonts, page layouts, and both vector and bitmap graphics.
In addition, PDF files can contain electronic document search and navigation features such as electronic links. The Touch Up Object tool is mainly for last-minute revisions to images and objects.
Photoshop PDF files. Photoshop PDF files can contain only a single image. Photoshop PDF format supports all color modes except Multichannel and features that are supported in standard Photoshop format.
Standard PDF files. Standard PDF files can contain multiple pages and images. When you open a standard PDF file, Photoshop rasterizes vector and text content, while preserving pixel content.
PICT format is used in Mac OS graphics and page-layout applications as an intermediary file format for transferring images between applications. However, Photoshop cannot save to this format. The Pixar format is designed specifically for high-end graphics applications, such as those used for rendering three-dimensional images and animation. Pixar format supports RGB and grayscale images with a single alpha channel.
The format can be used for lossless data transfer because many applications support this format. You can even edit or create such files within a simple text editor.
This format was originally developed for the Radiance system, a professional tool for visualizing lighting in virtual environments.
The file format stores the quantity of light per pixel instead of just the colors to be displayed onscreen. Radiance HDR files are often used in 3D modeling.
Contact Creo to obtain utilities for transferring files saved in Scitex CT format to a Scitex system. These files are generated for input using a Scitex scanner.
Images saved in Scitex CT format are printed to film using a Scitex rasterizing unit, which produces separations using a patented Scitex halftoning system. TIFF is a flexible bitmap image format supported by virtually all paint, image-editing, and page-layout applications. Also, virtually all desktop scanners can produce TIFF images. Photoshop can save layers in a TIFF file; however, if you open the file in another application, only the flattened image is visible.
