The TIFF filter allows Cumulus¬ to catalog TIFF files up to the specification version 6.0 of the TIFF standard.
The filter supports the following variations of TIFF:
Ñ Color models: Line art, Grayscale, RGB Color, CMYK Color, CIELAB Color.
Ñ Compression: None, PackBits, FAX Group 3, FAX Group 4, Lempel-Ziv, Lempel-Ziv 2.
Ñ Any number of bits per color channel.
Ñ Strips and tiles.
Ñ Chunky and planar color channels.
Cumulus also - optionally - supports Helios EtherShare OPI: Helios EtherShare OPI running on an Helios EtherShare file server automatically creates a layout (low resolution) file for each TIFF file (called ╥high resolution file╙) from that server as the file is closed. The layout file gets the same name as the high-resolution file with a special file name extension (usually ╥.lay╙). You place the layout file in your QuarkXPress or PageMaker document and later when printing the print spooler (also running on the Helios server) will automatically print the high resolution file instead of the layout file. This saves time when placing large images in your layout documents because you only use very small files.
You can setup the TIFF Filter to catalog either the layout file or the high-resolution file, to avoid duplication when cataloging a whole folder. To speed up cataloging the layout file is always used to create the thumbnail. The PageMaker and QuarkXPress adapters try to place the layout file with the name extension ╥.lay╙ which the OPI server automatically replaces with the high-resolution version at print time.
This filter supports EtherShare OPI version 1.0 up to 1.2.
The following type-specific information is available for TIFF files:
╩
Byte Order: The order in which numbers are stored into the TIFF file. Possible values are ╥Motorola╙ and ╥Intel╙.
Computer: The computer the image was created on (if available).
Artist: The person who created the TIFF file (if available).
Scanner Manufacturer: The manufacturer of the scanner used to scan the image (if available).
Scanner Model: The model of the scanner used to scan the image (if available).
Compression: The compression method used to write the image data into the TIFF file. Possible values are: ╥None╙, ╥PackBits╙, ╥FAX Group 3╙, ╥FAX Group 4╙, ╥Lempel-Ziv╙ and ╥Lempel-Ziv 2╙.
The TIFF Filter displays the following setup dialog where you can set options for support for Helios EtherShare OPI:
╩
Helios EtherShare OPI aware (default: ON): If this box is checked the filter will only catalog either the layout file or the high resolution files.
Layout file name extension (default: ╥.lay╙): You specify the name extension to identify layout files. You should always specify the same name extension that is used by the Helios EtherShare OPI system. A file in the same folder as the high resolution file that has this name extension will be treated as the layout file for this high resolution file.
Catalog high resolution files only (default: ON): This option allows you to catalog only high resolution files. This is useful to get the information (size, resolution) about those files into the Cumulus catalog. When placing the file into QuarkXPress or PageMaker the corresponding adapter will then place the corresponding layout file instead of this high resolution file.
Catalog layout files only (default: OFF): By choosing this option you can build a catalog of only the layout files.
