% An example logo character. Building the PostScript program that prints
|
||||
% your company logo is not addressed here; we assume you already have
|
||||
% such a program, that it's relatively simple, and that it prints the
|
||||
% logo by itself on a page. What you'll find here are instructions for
|
||||
% converting that logo program into a character that can be accessed by
|
||||
% troff and dpost.
|
||||
%
|
||||
% Building a new charlib character involves some PostScript programming.
|
||||
% We've tried to isolate parameters that you'll need to change (Xoffset,
|
||||
% Yoffset, and Scaling), but we can't guarantee things will work properly
|
||||
% with every logo program. PostScript is a complex language and subtle
|
||||
% interactions between your logo program and what we've done here can
|
||||
% cause problems.
|
||||
%
|
||||
% Tuning the new character is an iterative process. You may want to adjust
|
||||
% the size of the logo (via Scaling), it's position relative to adjacent
|
||||
% characters and the baseline (Xoffset and Yoffset), and the distance troff
|
||||
% moves after printing the character (width field in file ../S1). The steps
|
||||
% to follow are:
|
||||
%
|
||||
% 1: Create a simple troff test file for the new character. Something
|
||||
% like,
|
||||
%
|
||||
% .sp 1i
|
||||
% .ps 10
|
||||
% size 10: \(LH
|
||||
% .sp 1i
|
||||
% .ps 18
|
||||
% size 18: \(LH
|
||||
% .sp 1i
|
||||
% .ps 36
|
||||
% size 36: \(LH
|
||||
% .sp 1i
|
||||
% .ps 10
|
||||
% four logo characters: \(LH\(LH\(LH\(LH
|
||||
%
|
||||
% is sufficient. The test file can go anywhere.
|
||||
%
|
||||
% 2: Change into directory /usr/lib/font/devpost/charlib. All file
|
||||
% pathnames will be relative to that directory.
|
||||
%
|
||||
% 3: Save a copy of the working LH logo file. Then replace LH with
|
||||
% this file (i.e. LH.example). Changes described below should be
|
||||
% be made in the new LH file (not in LH.example).
|
||||
%
|
||||
% 4: Your PostScript logo program will eventually replace whatever
|
||||
% you find between the <<StartLogo>> and <<EndLogo>> comment lines
|
||||
% in the PostScript build_LH procedure (below). What's there now
|
||||
% prints an example logo that you can use until you understand the
|
||||
% remaining steps.
|
||||
%
|
||||
% 5: Print your troff test file using (assuming your making changes
|
||||
% in the devpost charlib directory),
|
||||
%
|
||||
% troff -Tpost testfile | dpost | lp ...
|
||||
%
|
||||
% 6: Adjust the logo positioning by changing the numbers assigned to
|
||||
% Xoffset and Yoffset (below). Both are in units of 72 per inch.
|
||||
% Positive offsets should move the logo to the right and up the
|
||||
% page.
|
||||
%
|
||||
% 7: Adjust the logo size by changing the the number assigned to
|
||||
% Scaling. Unitsize also controls scaling, but there's no good
|
||||
% reason to change both Scaling and Unitsize.
|
||||
%
|
||||
% 8: Control the horizontal distance troff moves after printing the
|
||||
% new LH character by changing the width (i.e. the number in the
|
||||
% second column) assigned to LH in file ../S1. Character width
|
||||
% adjustments should probably wait until you're satisfied with
|
||||
% the Scaling set in step 7.
|
||||
%
|
||||
% 9: Back to step 5 until your satisfied with the output.
|
||||
%
|
||||
% The remaining steps are suggested but not required:
|
||||
%
|
||||
% 10: Delete PostScript comments in your new LH charlib file - comments
|
||||
% start with % and go to the end of the line.
|
||||
%
|
||||
% 11: Update the width field assigned to LH in file ../shell.lib. The
|
||||
% new width should reflect what's currently in your S1 font file.
|
||||
%
|
||||
% 12: Make a similiar set of changes in /usr/lib/font/devLatin1/charlib.
|
||||
% You can use the devpost version of LH to devLatin1/charlib/LH,
|
||||
% but changes to files devLatin1/S1 and devLatin1/shell.lib must be
|
||||
% entered by hand.
