Setting TIFF File Compression Options
When TIFF file (*.tif) is selected for the file type in Save Page As dialog box, the compression format
specified here is applied.
1 Click TIFF File in the Options menu.
The TIFF File Settings dialog box appears.
2 Select the image type (Black and White, or Grayscale or Color).
3
Select the compression format from the list box.
CCITT Group 4 can be selected when the image type is black and white, and OLD JPEG(6) or JPEG(7)
can be selected when the image type is grayscale or color. If compression is set to None, saved files
may be quite large.
Note
• CCITT Group 4
This compression format is used by faxes and other such devices for data transmission, and is used
to compress black and white images.
• OLD JPEG(6) and JPEG(7)
These compression formats are for saving grayscale and color images. When OLD JPEG(6) or
JPEG(7) is selected, the value set in the JPEG File Setting dialog box is applied.
Important
• OLD JPEG(6) is the JPEG format supported by Image Viewer that was bundled with Windows prior to
Windows 2000, and is no longer supported by the Windows Image and Fax Viewer bundled with
Windows XP.
• JPEG(7) is not supported by Image Viewer that was bundled with Windows prior to Windows 2000.
• The compression format supported by CapturePerfect may not be supported by other applications. If
a TIFF file saved by CapturePerfect cannot be opened by another application, set the compression to
None and save it again.
