Merge the preview mechanism for lilypond-book with the standard one.
- Handle the preprocessing in the main lyxpreview script with the
command-line arguments --lilypond and --lilypond-book=exe.
- Remove the obsoleted file lyxpreview-lytex2bitmap.py and the
corresponding lines in configure.py.
Fix for the japanese preview still to come.

# This script takes a LaTeX file and generates a collection of
|
||||
# png or ppm image files, one per previewed snippet.
|
||||
|
||||
# Pre-requisites:
|
||||
# * A latex executable;
|
||||
# * preview.sty;
|
||||
# * dvipng;
|
||||
# * pngtoppm (if outputing ppm format images).
|
||||
|
||||
# preview.sty and dvipng are part of the preview-latex project
|
||||
# http://preview-latex.sourceforge.net/
|
||||
|
||||
# preview.sty can alternatively be obtained from
|
||||
# CTAN/support/preview-latex/
|
||||
|
||||
# Example usage:
|
||||
# lyxpreview-lytex2bitmap.py png 0lyxpreview.tex 128 000000 faf0e6
|
||||
|
||||
# This script takes six arguments:
|
||||
# FORMAT: The desired output format. Either 'png' or 'ppm'.
|
||||
# TEXFILE: the name of the .tex file to be converted.
|
||||
# DPI: a scale factor, used to ascertain the resolution of the
|
||||
# generated image which is then passed to gs.
|
||||
# FG_COLOR: the foreground color as a hexadecimal string, eg '000000'.
|
||||
# BG_COLOR: the background color as a hexadecimal string, eg 'faf0e6'.
|
||||
# CONVERTER: the converter (optional). Default is latex.
|
||||
|
||||
# Decomposing TEXFILE's name as DIR/BASE.tex, this script will,
|
||||
# if executed successfully, leave in DIR:
|
||||
# * a (possibly large) number of image files with names
|
||||
# like BASE[0-9]+.png
|
||||
# * a file BASE.metrics, containing info needed by LyX to position
|
||||
# the images correctly on the screen.
