In general gv does not depend on any external resource files. However, when starting gv, preferences are read from
The files "gv_user.ad" and "gv_system.ad" (located in the library directory of gv, which is most probably either "/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis for constructing the user and system specific resource files.
Note that the user and system specific resource files are not the only sources of preferences taken into account when gv is started. However, in practice these are the most important.
Resources of gv
The following describes some of the resources of gv. The precise syntax of some of the resource values may be inferred from the appended default system specific resource file.
Whether antialiasing should be used. Valid values are "True" and "False".
Whether the displayed page should automatically be centered (for instance when opening a new file). Valid values are "True" and "False".
Whether gv is allowed to resize the main window according to the size of the current page. Valid values are "True" and "False".
Whether printing requires an extra confirmation. Valid values are "True" and "False".
Whether leaving gv requires extra confirmation. Valid values are "0" (Never), "1" (When processing) and "2" (Always). The default value is "1", which causes a confirmation request when trying to leave gv in the presence of pending PDF to Postscript conversions.
If this resource is "True" scrolling via the keyboard causes a temporary border to be drawn around the previously visible area of the page. Allowed values are "True" and "False".
Defines the behaviour of the postscript scanner as described in the Options section. Valid values are "True" and "False".
Determines whether gv should attempt to respect document structuring comments. Valid values are "True" and "False".
Defines the interpretation of directions when scrolling with the mouse. Valid values are "True" and "False".
Whether the meaning of "landscape" and "seacape" should be interchanged. Valid values are "True" and "False".
Specifies a directory used to store temporary data.
Specifies the default destination directory for files to be saved.
If the value of this resource is "False" the X Server is advised that saving off-screen pixels of the displayed page would be beneficial (maintaining backing store). In this case gv does not actively maintain the contents of the page but relies on the X Server. The server is, however, always free to stop maintaining backing backing store. If the value of this resource is "True" the X Server is advised that maintaining backing store is not useful. In this case gv attempts to allocate a sufficiently large pixmap to store the contents of the displayed page.
Whether the document should be checked periodically and updated automatically if changes are detected. Valid values are "True" and "False".
Defines the time in milliseconds elapsing between successive checks of the document when watchFile is set to "True". Allowed values must be larger than 500.
The command used for printing a file. The command may contain multiple '%s' wildcards which will be replaced by the name of the file to be printed.
The command used to start the ghostscript interpreter.
The command used to extract document structuring comments from a PDF file.
The command used to convert a PDF file to PostScript.
The ghostscript command line option which activates the "X11" device.
The ghostscript command line option which activates the "X11" device with antialiasing enabled.
Determines whether ghostscript should be started with the "-dSAFER" command line option.
Determines whether ghostscript should be started with the "-dQUIET" command line option.
May be used to provide additional command line options for the ghostscript interpreter. Starting gv with the "-arguments <arguments>" option will override this resource setting.
Describes the menu that pops up when preparing to to zoom an area of the displayed page.
Defines a list of directories accessible via the Directories menu in the file selection window. The special value "Home" corresponds to the users home directory, the value "Tmp" corresponds to the scratch directory as defined by the scratchDir resource.
Defines the default filter to be used when displaying a directory contents in the file selection window. A filter is specified according to the syntax
<filter> := [<filespecs>] [no <filespecs>] <filespecs> := <filespec> [<filespecs>] <filespec> := filename possibly including wildcards '*' which match any character.Example: The filter
GV*filter: *.ps *.pdf no .*screens out all files with names starting with a dot and keeps of the remaining ones only those which end on ".ps" or ".pdf".
Defines a list of filters offered in the Filters menu of the file selection window. The filter "None" has a special meaning causing all files to be displayed when the corresponding menu entry is selected.
Describes the menu that pops up when clicking with the third mouse button on the displayed page. The value of this resource is a list of menu entries. Allowed entries are "update", "redisplay", "toggle_current", "toggle_even", "toggle_odd", "unmark", "stop", "print_all", "print_marked", "save_all", "save_marked" and "line".
Whether the name of the displayed document should be shown in the title bar of the window. The name of gv's icon will also change accordingly if this resource is set to "True".
When resizing gv will not attempt to exceed the size specified by these resources. These resources may be specified as a positive integer or as "screen", optionally combined with a positive or negative offset. The default values listed above provide examples for this syntax. "screen" will automatically be replaced by the size of the screen.
Defines a minimum size for the main window. Valid values for both resources are positive integers larger than 200.
Sets the initial scale. The value of this resource is the offset of the scale to be selected relative to the scale 1.0 in the the "Scale" menu.
Selects the initial scale base. The value of this resource should be a positive integer.
Defines the available scales bases and scales in the "Scale" menu.
Sets the initial orientation. Valid values are "portrait", "landscape","seascape", "upside-down" and "automatic". "automatic" causes gv to attempt to derive the correct orientation from document structuring comments.
Defines the paper-size to be used when automatic orientation detetction fails. Valid values are "portrait", "landscape","seascape" and "upside-down".
A list describing the page medias known to gv. List entries starting with "!" or "#" will not appear in the "Media" menu but will still be used for automatic paper size detection.
Sets the paper size. Allowd values are as given in the above list of paper-sizes. Specifying "automatic" causes gv to attempt to derive the correct paper-size from document structuring comments.
Defines the paper-size to be used when automatic paper-size detetction fails. Valid values are as given in the above list of paper-sizes.
