'\" '\" .AP type name in/out ?indent? '\" Start paragraph describing an argument to a library procedure. '\" type is type of argument (int, etc.), in/out is either "in", "out", '\" or "in/out" to describe whether procedure reads or modifies arg, '\" and indent is equivalent to second arg of .IP (shouldn't ever be '\" needed; use .AS below instead) '\" '\" .AS ?type? ?name? '\" Give maximum sizes of arguments for setting tab stops. Type and '\" name are examples of largest possible arguments that will be passed '\" to .AP later. If args are omitted, default tab stops are used. '\" '\" .BS '\" Start box enclosure. From here until next .BE, everything will be '\" enclosed in one large box. '\" '\" .BE '\" End of box enclosure. '\" '\" .CS '\" Begin code excerpt. '\" '\" .CE '\" End code excerpt. '\" '\" .VS ?version? ?br? '\" Begin vertical sidebar, for use in marking newly-changed parts '\" of man pages. The first argument is ignored and used for recording '\" the version when the .VS was added, so that the sidebars can be '\" found and removed when they reach a certain age. If another argument '\" is present, then a line break is forced before starting the sidebar. '\" '\" .VE '\" End of vertical sidebar. '\" '\" .DS '\" Begin an indented unfilled display. '\" '\" .DE '\" End of indented unfilled display. '\" '\" .SO '\" Start of list of standard options for a Tk widget. The '\" options follow on successive lines, in four columns separated '\" by tabs. '\" '\" .SE '\" End of list of standard options for a Tk widget. '\" '\" .OP cmdName dbName dbClass '\" Start of description of a specific option. cmdName gives the '\" option's name as specified in the class command, dbName gives '\" the option's name in the option database, and dbClass gives '\" the option's class in the option database. '\" '\" .UL arg1 arg2 '\" Print arg1 underlined, then print arg2 normally.

See it for examples and language reference\&. .SS "USE CASES" \fBdiagram-viewer\fR was written with the following two use cases in mind\&. .PP .IP [1] Processing and display of one or more diagram files\&. .IP [2] Batch conversion of one or more diagram files into raster image files\&. .PP .PP .SS "COMMAND LINE" .TP \fBdiagram-viewer\fR \fBshow\fR \fIinputfile\fR\&.\&.\&. This is the form for use case [1]\&. The application opens a gui showing the list of input files to the left, allowing the user to choose which of them to render to the canvas on the right\&. .TP \fBdiagram-viewer\fR \fBconvert\fR \fB-o\fR \fIoutput\fR \fIformat\fR \fIinputfile\fR\&.\&.\&. This is the form for use case [2]\&. The application converts the input files into raster image of the specified \fIformat\fR\&. .RS .TP path \fIoutput\fR (in) This argument specifies where to write the generated image\&. It can be the path to a file or directory\&. .sp If the \fIoutput\fR does not exist then [file dirname $output] has to exist and must be a writable directory\&. .sp In case of multiple input files the generated image will be written to a file in the directory, and the name of that file will be derived from the \fIinputfile\fR, and \fIformat\fR\&. .sp In case of a single input file the generated image will be written to the file\&. .TP (handle) \fIformat\fR (in) This argument specifies the image format to convert the diagrams into when processing the input\&. The application recognizes all formats supported by the \fBImg\fR package, i\&.e\&. for which it can load a package \fBimg::\fBformat\fR\fR .TP path \fIinputfile\fR (in) This argument specifies the path to the diagram file to process\&. It has to exist, must be readable, and written in \fIdiagram\fR format\&. .RE .sp .PP .SH "BUGS, IDEAS, FEEDBACK" This document, and the application it describes, will undoubtedly contain bugs and other problems\&. Please report such in the category \fIdiagram\fR of the \fITcllib SF Trackers\fR [http://sourceforge\&.net/tracker/?group_id=12883]\&. Please also report any ideas for enhancements you may have for either application and/or documentation\&. .SH KEYWORDS canvas, conversion, diagram, vector .SH CATEGORY Documentation tools .SH COPYRIGHT .nf Copyright (c) 2010 Andreas Kupries .fi
