HELIOS ImageServer Benutzerhandbuch |
Hinweis: Gewöhnlich können fast alle Präferenzen für Programmfunktionen und für das Verhalten der HELIOS Produkte mit EtherShare Admin oder PCShare Admin gesetzt werden. Es ist also nicht notwendig, Präferenzen manuell zu bearbeiten. Trotzdem werden im Folgenden die einzelnen Präferenzen sowie ihre Funktionsweise beschrieben. Dieses Kapitel wurde nicht übersetzt, um die Eindeutigkeit der Beschreibung zu bewahren.
Die Server-Präferenzen sind in einer Binärdatei gespeichert. Die vorgegebenen Werte werden von den HELIOS Diensten verwendet, wenn keine anderen Werte angegeben sind.
Nicht alle der folgenden Präferenzen sind von vornherein gesetzt, d. h. sie werden nicht in einer "prefdump"-Ausgabe aufgelistet. Die HELIOS Produkte verwenden die vorhandenen Voreinstellungen. Wenn mit Hilfe des "prefvalue"-Befehls ein anderer Wert gesetzt wird, dann hat dieser Vorrang. Um wieder zu den voreingestellten Werten zurückzukehren, müssen Sie den Präferenzeintrag löschen.
Das Exportieren, Setzen/Löschen und Importieren von Präferenzen auf dem HELIOS Host-Computer wird mit den Programmen "prefdump", "prefvalue" und "prefrestore" erledigt. Eine detaillierte Beschreibung dieser Programme finden Sie im HELIOS Base 1.1 Benutzerhandbuch.

This preference determines the time delay in seconds after which the layout file is generated from the original image file.
This parameter controls the maximum number of "opisrv" processes that may run simultaneously. Default is the number of physically available processors.
The priority of the "opisrv" processes - compared to other executable programs on the OPI Server - can be changed. This UNIX parameter lets you increase/reduce the priority, and therefore the speed of a program. The higher the priority of a program, the less "nice" its behavior towards other applications. The values for NiceIncr are as follows:
Specifies the facility which is used for system log messages. The string names the log facility. The default value depends on the program and is daemon for the "opisrv" program and user for the "layout" program. Valid names are listed below (please note that some names are not supported on every architecture):
"audit", "sat", "auth", "security", "cron", "daemon", "kern", "lpr", "mail", "news", "syslog", "user", "uucp", "local0", "local1", "local2", "local3", "local4", "local5", "local6" and "local7".
While logging on to the SLP server, each process sends along a "lifetime" value (in seconds). At intervals, the SLP server verifies that each service is still running. If so, it renews the lifetime. Otherwise, the SLP server removes the process registration from its list.
strlist RGB="ICC-Profiles:Scanner:
HELIOS:CCIR-EBU-RGB",
CMYK="ICC-Profiles:Printer:
HELIOS:Euro 2.6 UCR-370"
Defines RGB or CMYK profiles used if the color space for the destination layout file and the color space of the highresolution file are different. These profiles are used to match between color spaces properly. Each string has the format <color space>=<path name>.
If set to TRUE, this preference causes that an existing clipping path is ignored when creating a layout image. See 3.3.3 "Beschneidungspfade" and 5.3 "Festlegen von ordnerspezifischen OPI-Einstellungen" for a description.
This preference default causes that additional channels (e.g. spot colors) are used when creating a layout image. See 3.3.5 "Zusätzliche Kanäle in Pixelbildern" and 5.3 "Festlegen von ordnerspezifischen OPI-Einstellungen" for a description.
Controls the TCP/IP port number where to listen for OPI event registration requests. If this parameter is not set, "opisrv" uses the port number given by the TCP service "OPIEvent". If this service is not defined it uses the default port number 2002.
If set to TRUE, this preference causes that a layout image is created from a PDF file. The setting of this attribute reflects that of the PDF OPI Layout Generation checkbox in EtherShare Admin's Lists > PDF Settings menu.
A generated layout will contain an embedded profile, even if the original image only contains a reference. This preference is only applicable if the UseProfile option is also set. Useful, if the layout will be used on a different computer and where the specified profile might not be available.
A generated layout/picture will not contain any profile even if a profile was specified for the generation of the layout/original. This option is useful if the generated layout/picture is small while the specified profile was large.
This preference applies to composite printing only:
Spot colors are output in Level 2 Separation color space. This becomes necessary when printing to a Create PDF printer queue or to in-RIP separation devices, in order to preserve the spot colors. If set to FALSE, all spot colors that are incorporated in the image are converted to the process colors of the output color space, e.g. CMYK.
If set to TRUE, the printouts from the specific printer queue will only contain layout images. The copies of the images - which you have used for layouting your document - will be sent to the OPI server and then be replaced by the layout files instead of the high-resolution originals.
With this preference set to TRUE, the OPI server will try to find all images that are included in a print job. If any images are missing, the job will be stopped, and issue an error message for every missing file. If CheckImages is set to FALSE, single images may be missing on the printouts.
This preference will induce the OPI server to check whether all image profiles that have been tagged to any of the image files are available. The server will automatically stop the print job if a single profile is missing and issue a corresponding error message. If you set CheckICCProfiles to FALSE, OPI will execute all print jobs and use standard profiles for color matching whenever the correct profile is missing.
This preference should only be set to TRUE if you print to a PostScript 3 device with in-RIP separation. The PostScript output of PDF original files will be optimized to use the PostScript 3/DeviceN features. This applies for Hexachrome® printing, colorized images (Duotone), etc.
When printing host-based separations with applications like QuarkXPress, this feature must be turned off, otherwise the output will lead to unexpected results.
If set to TRUE, this preference will induce the OPI server to issue an error message if the current print job contains any fonts that are not available.
If set to FALSE, the OPI server will only replace layout images during printing. High-resolution originals you may have placed in your document, will not be replaced. In case you want the OPI server to replace all images during printing (e.g. if you want to use the Omit... options in the print dialog) you should set this preference to TRUE.
Defines a uniform output resolution for all raster-based images - no matter whether you print layout images or high-resolution originals. The resolution for downsampling may be specified with the Resolution preference (see below).
With DownSampling (see above) set to TRUE, the resolution of an image can be specified with this preference. If the resolution of a given image (e.g. 300 dpi) is higher than the value in this dialog (e.g. 222,30 dpi), the OPI server will apply the value you have chosen for downsampling and then re-calculate and scale the image accordingly. Images with a resolution smaller than the value entered in this dialog, will remain unchanged because increasing the resolution automatically decreases the dimensions of an image. This would entail upward scaling and lead to a loss in quality.
This preference allows fixing the downsampling resolution (see Resolution parameter above) to the given value. Usually, if this parameter is set to FALSE, the output resolution is adjusted to the image resolution if the image resolution is smaller. When setting this parameter to TRUE the printer interfaces will use the given Resolution as is for downsampling. This may cause upsampling of images with resolutions smaller than the given one. This parameter is only meaningful when setting the DownSampling parameter to TRUE.
This option selects a compression mode for images while being printed. CCITTG4, JPEG, Flate, and Compress are currently supported.
For this preference, the key must be extended to "Printers/<printer queue>/PostScriptImage
/<color space>/CompressPostScript".
With the CompressPostScript preference selected, this preference controls the output quality of JPEG-compressed PostScript images. Valid values are 1...100.
For this preference, the key must be extended to "Printers/<printer queue>/PostScriptImage
/<color space>/PrintCompressQuality".
Specifies whether in case of resolving an already resolved PostScript job, the use of fonts and other resources should still be accounted.
Specifies a list of path names where to search high-resolution images during image replacement, in case they cannot be found in the standard locations.
Specifies a list of volume names where to search high-resolution images during image replacement, in case they cannot be found in the standard locations.
This preference - if it is set to TRUE - enables the use of the EtherShare desktop database to locate moved image files.
This preference specifies the path name of the default ICC profile describing the printing device. Can be overridden using the HELIOS ColorSync 2 XT.
This preference specifies the path name of the default ICC profile describing the proof device. The string will only be recognized if a default printer profile is set. Can be overridden using the HELIOS ColorSync 2 XT.
This preference sets the color space used while printing separations. The default is CMYK for a four color print process. Spot colors are not affected by this parameter. Valid color spaces are "CMYK" and "Multi". If you set the string to "Multi" you have to define the names and order of the color components. Furthermore, the usage of the "Multi" color space requires the use of ICC profiles. For (future) ICC profiles that include the names of the color components this preference will become obsolete. Note that the value you choose for this preference can be overridden by the printer profile you have selected using HELIOS ColorSync 2 XT or using DefaultPrinterProfile.
This preference controls, in conjunction with the ProcessColorspace preference, the names of the process inks used for separations. Spot colors are not affected.
This preference sets the color space used while printing composite. The default is CMYK. Setting this preference to None causes all color images in a print job to be kept and printed in their original color space. This applies to CMYK,
CIE- Lab and RGB images only. Valid strings are "CMYK", "RGB", and "CIELab". Please note that the value you choose for this preference can be overridden by the printer profile you have selected using HELIOS ColorSync 2 XT or using the DefaultPrinterProfile preference.
This parameter enables the use of the ICC info files while printing images. If it is set to TRUE, every non-tagged image will be temporarily tagged during printing provided that the ICC info file specifies tagging for that kind of image.
Use this parameter to specify whether non-existing layout images should be ignored when printing layout quality.
This parameter controls whether non-tagged images should be ignored when printing to an ICC color matched queue.
Forces layout images to always contain only the default inks of the layout color space. Spot colors defined in a high-resolution image will be converted into the appropriate values of the layout color space.
Note: It is recommended that the value for MaxProc be less or equal to the number of physical CPUs.
File changed events will be reported to custom applications via the ImageServer TCP/IP connection. This can be issued via the command:
telnet localhost 2002
Type help for the command overview.
Show the "opisrv" event queue as a list of files which are waiting to be processed into layout images. ushowq additionally includes the user ID of the job initiator.
Show list of exported volumes by EtherShare and PCShare and can be used to map the path name to the corresponding volume.
Send a layout event to the registerlayout clients. This is usually done by the "layout" and "opisrv" programs.
Register for layout events. Whenever a new layout file is generated, the path name of the new file will be reported.
Register for file change events with a particular Macintosh file type. The "opisrv" process will report all changes for a given file type done by an EtherShare file server. For example, registertype "EPSF" will report a list of all file changes of the type EPSF. registertype "\0\0\0\0" is a "wildcard" register to report all file changes done by Macintosh AFP clients. The "\0\0\0\0" option should be used carefully because it can cause hundreds of events per second and hence may dramatically slow down the server performance.
Register for file change events with a particular Windows file suffix. The "opisrv" process will report all changes for a given file suffix done by a PCShare file server. For example, registersuffix ".eps" will report a list of all file changes of the file suffix .eps. registersuffix "\0" is a "wildcard" register to report all file changes done by Windows SMB clients. The "\0" option should be used carefully because it can cause hundreds of events per second and hence may dramatically slow down the server performance.
