62 Scanning from HP Precisionscan Pro Image file formats l GIF. GIF is a compressed file format suitable for an image that will be used on the Web or on multiple platforms. Cannot be used with True Color output type. l JPEG. JPEG is a compressed file format for images. Its strengths are small file sizes and speed. The trade-off for these advantages, though, is reduced image quality. Because each time an image is compressed with JPEG it loses a little of the image data, avoid compressing a file with JPEG more than once. JPEG is an appropriate file format for an image that will be used on the Web or on multiple platforms. You can save your JPEG file as a progressive JPEG. When used on a Web page, a progressive JPEG is initially sent as just every other line, with the remaining lines sent immediately after. This allows a (somewhat blurry) image to display sooner. Most people prefer this. JPEG can be used only with True Color and Grayscale output types. l PNG. A compressed image file format that might replace GIF. Like GIF, PNG uses non-lossy compression, which means all the visual data is saved and restored when the file is decompressed. Unlike GIF, PNG can be used with True Color and Grayscale output types. l PICT. Apple's proprietary image file format that is used by the Macintosh operating system. Designed for the screen, this format is best used for color images that will not be printed. Images saved as PICT files are smaller in size than images saved as a TIFF files. l PDF. PDF is a format useful for text, photos, and drawings. Use Adobe Acrobat Reader to view PDF files. If no changes need to be made to the file, this file type is useful for sharing (as through e-mail) and filing because of its generally small file size. When using the Macintosh version of the scanning software, you can only create image-only PDF files; you cannot copy text from these files. Back to TOC l TIFF. Usually created by scanners, TIFF files are widely accepted by programs that work with photographs and other images. A TIFF file is a bitmapped graphic (also called a raster graphic) and can be any resolution. TIFF image files can be used on multiple platforms. l TIFF compressed. TIFF compressed files for images are smaller than standard TIFF files. Text or text-and-image file formats l HTML. HTML is useful for text and graphics that will be viewed on the World Wide Web. When this format is selected for a scanned image containing both text and images, the text is converted to editable text and is saved as HTML, and the graphics are saved as GIF or JPEG files. l Rich Text. The RTF format can be used with a page that contains text or text and pictures. The formatting of text in an RTF file can usually be retained and then interpreted by other programs. l Text. Use text file format for saving only the text in the selection area. Text will be editable, unformatted, ASCII text.
