<P><A NAME="INPUT"><A HREF="#CONTENTS">Contents</A> |
<A HREF="#LOADSAVE">Loading and Saving Books</A></A>

<H1>The Input Tab</H1>

The input tab lists all of the source files that are used to generate the
document. You can also specify the type of document (book or web page) and the
title and logo images.

<H2>Setting the Document Type</H2>

Normally HTMLDOC generates indexed documents from your structured source files.
To convert a single unstructured document (or "web page") click on the
<I>Continuous</I> or <I>Web Page</I> radio buttons. The <I>Web Page</I> type
inserts page breaks between each file or URL, while the <I>Continuous</I> type
does not.

<P>Structured HTML files use heading elements (<CODE>H1</CODE>, <CODE>H2</CODE>,
etc.) to delineate chapters and headings within a document.

<H2>Adding Input Files</H2>

<P>Click on the <I>Add File(s)...</I> button to add one or more HTML or Markdown
files to your <CODE>.BOOK</CODE> file.

<H2>Adding URLs</H2>

<P>Click on the <I>Add URL(s)...</I> button to add one or more URLs to your
<CODE>.BOOK</CODE> file.

<H2>Deleting Input Files</H2>

<p>Highlight the file(s) in the input file list and then click on the
<I>Delete</I> button to remove one or more source files from your document. The
files are removed from your document but are <I>not</I> deleted from disk.</p>

<H2>Editing Input Files</H2>

<p>Highlight the file(s) in the input file list and then click on the
<I>Edit...</I> button to edit one or more source files in your document. By
default this starts the <I>gedit</I> editor under Linux, the <i>bbedit</i>
editor under macOS, and the <I>Notepad</I> editor under Windows.</p>

<P>The editor can be changed in the <A HREF="#OPTIONS">Options Tab</A>.

<H2>Reordering Input Files</H2>

Highlight the file(s) in the input file list and then click on the <I>Move
Up</I> or <I>Move Down</I> buttons to change the order of the input files.

<H2>Selecting a Logo Image</H2>

<p>The logo image can be shown in the header or footer of pages in the
PostScript and PDF output files. Click on the <I>Browse</I> button to select a
logo image file using the file chooser.</p>

<H3>Selecting a Title File or Image</H3>

<p>The title file or image is used for the title page. Click on the
<I>Browse</I> button to select a title file using the file chooser.</p>

<HR>

<P><A NAME="OUTPUT"><A HREF="#CONTENTS">Contents</A> |
<A HREF="#LOADSAVE">Loading and Saving Books</A></A>

<H1>The Output Tab</H1>

<p>The output tab specifies where your document will be generated, the output
format, and some of the output options.</p>

<H2>Selecting File or Directory Generation</H2>

<p>HTMLDOC can generate a single EPUB, HTML, PDF, or PostScript file, or a
series of files to a directory when generating HTML or PostScript output.</p>

<P>Click on the <I>File</I> radio button to select single file output.
Click on the <I>Directory</I> radio button to generate multiple files
to a directory.</p>

<H2>Selecting an Output File or Directory</H2>

<p>The output file is the EPUB, HTML, PostScript, or PDF file you wish to
generate from your source files. Click on the <I>Browse</I> button to select an
output file using the file chooser.</p>

<H2>Selecting the Output Format</H2>

<p>Click on the corresponding <I>Output Type</I> radio button to select an
output format. You can select the PostScript language level in the
<A HREF="#PS">PS Tab</A> and the PDF version in the <A HREF="#PDF">PDF Tab</A>.

<H2>Selecting Grayscale Output</H2>

<p>When generating PostScript or PDF files you can choose to convert all images
to grayscale. This is necessary for many Level 1 printers that do not support
color images and can reduce the size of output files considerably.</p>

<P>Click in the <I>Grayscale</I> check box to enable or disable grayscale
output.</p>

<H2>Title Page</H2>

<p>The title page is the first page in your generated file.  Click in the
<I>Title Page</I> check box to turn the title page on or off.</p>

<H2>JPEG Big Images</H2>

<p>JPEG compression is a great way to reduce the size of large photographic
or continuous-tone images. It is supported when generating PDF, PostScript
Level 2, and PostScript Level 3 output. HTMLDOC uses JPEG compression when the
output image cannot be reduced to 256 colors or less.</p>

<P>Click in the <I>JPEG Big Images</I> check box to enable or disable
JPEG compression.</p>

<H2>JPEG Quality</H2>

<p>Drag the <I>JPEG Quality</I> slider to change the JPEG quality setting.
The JPEG quality setting determines the relative quality of the compressed
image. Since JPEG is a <I>lossy</I> compression algorithm, higher
compression generally yields lower quality. Typically a quality of 75 or
higher provides excellent image quality with a high amount of compression.</p>

<H2>Compression</H2>

<p>PDF 1.2, PDF 1.3, PDF 1.4, and Level 3 PostScript files can be compressed
using Flate (a.k.a. ZIP) compression to substantially reduce the size of files.
Drag the <I>Compression</I> slider to set the amount of compression to use.</p>

<P>Unlike JPEG, the Flate algorithm is lossless and will not cause any
loss of visual quality at any level of compression.</p>

<P><A NAME="PAGE"><A HREF="#CONTENTS">Contents</A> |
<A HREF="#LOADSAVE">Loading and Saving Books</A></A>

<H1>The Page Tab</H1>

<P>The page tab defines the page header, footer, size, and margins for
PostScript and PDF output.

<H2>Page Size</H2>

<P>The page size option is only available for PostScript and PDF output.
HTMLDOC supports the following standard page size names:

<UL>
	<LI>A3 - 11.69x16.54in (297x420mm)
	<LI>A4 - 8.27x11.69in (210x297mm)
	<LI>Legal - 8.5x14in (216x356mm)
	<LI>Letter - 8.5x11in (216x279mm)
	<LI>Tabloid - 11x17in (279x432mm)
	<LI>Universal - 8.27x11in (210x279mm)
</UL>

<P>Click on the <I>Page Size</I> arrow button to select a standard page
size. You can specify a custom page size by double-clicking on the page
size text and entering the page width and length separated by the letter
"x". Append the letters "in" for inches, "mm" for millimeters, or "cm"
for centimeters.

<P><B>Note:</B> This option does not set the page size on the printer.
It only generates pages using the specified size. See the <A HREF="#PS">PS
Tab</A> to enable printer commands for PostScript printers.

<H2>2-Sided</H2>

<P>Click in the <I>2-Sided</I> check box to select double-sided (duplexed)
output.

<P><B>Note:</B> This option does not select duplexing on the printer.
It only generates pages with the left/right margins swapped on even
numbered pages and forces all chapters (and the table-of-contents) to
start on an odd-numbered page. See the <A HREF="#PS">PS Tab</A> to enable
printer commands for PostScript printers.

<H2>Landscape</H2>

<P>Click in the <I>Landscape</I> check box to select landscape output.

<H2>Page Margins</H2>

<P>The left, right, top, and bottom margins can be changed by clicking in the
appropriate text field and entering a new margin.  Append the letters "in"
for inches, "mm" for millimeters, or "cm" for centimeters.

<H2>Header and Footer</H2>

<P>Select the desired text from each of the option buttons to customize the
header and footer for the document/body pages. The left option buttons
set the text that is left-justified, the middle buttons set the text
that is centered, and the right buttons set the text that is right-justified.

<P>The left and right header and footer are swapped automatically when
generating duplexed output.

<H2>Number Up</H2>

<P>The <I>Number Up</I> chooser selects the number of document
pages that will appear on each output page. Click on the chooser
to select a different number of pages.

<HR>

<P><A NAME="TOC"><A HREF="#CONTENTS">Contents</A> |
<A HREF="#LOADSAVE">Loading and Saving Books</A></A>

<H1>The Table-Of-Contents Tab</H1>

The table-of-contents tab defines the number of levels in the
table-of-contents and the page header and footer that are used when
generating PostScript and PDF files.

<H2>Customizing the Table of Contents</H2>

To change the number of header levels listed in the table of contents, or to
turn off table-of-contents generation entirely, click on <I>Table of Contents</I>
chooser and select the number of levels desired.

<H2>Numbering Table of Contents Headings</H2>

To number the headings in your document, click on the <I>Numbered Headings</I>
toggle button.

<H2>Customizing the Header and Footer</H2>

To customize the header and footer for the table-of-contents pages, select the
desired text from each of the option buttons.  The leftmost option buttons
set the text that is left-justified, while the middle buttons set the text that
is centered and the right buttons set the text that is right-justified.

<H3>Title</H3>

Enter the desired title for the table-of-contents in the <I>Title</I>
field.

<HR>

<H1>The Colors Tab</H1>

The colors tab specifies the colors and background image that should be
used for the document.

<H2>Body Color</H2>

The <VAR>Body Color</VAR> field specifies the default background color. It
can be a standard HTML color name or a hexadecimal RGB color of the
form <CODE>#RRGGBB</CODE>. Click on the <VAR>Lookup...</VAR> button to
