.SH DESCRIPTION
.PP
pdf2htmlEX is a utility that converts PDF files to HTML files.

pdf2htmlEX tries its best to render the PDF precisely, maintain proper styling, while retaining text and optmizing for Web.

Fonts are extracted form PDF and then embedded into HTML (Type 3 fonts are not supported). Text in the converted HTML file is usually selectable and copyable. 

Other objects are rendered as images and also embedded.

Specify owner password
.TP
.B -u, --user-password <password>
Specify user password
.TP
.B --dest-dir <dir> (Default: ".")
Specify destination folder
.TP
.B --data-dir <dir> (Default: @CMAKE_INSTALL_PREFIX@/share/pdf2htmlEX)
Specify the folder holding the manifest and other files
.TP
.B -f, --first-page <num> (Default: 1)
Specify the first page to process
.TP
.B -l, --last-page <num> (Default: last page)
Specify the last page to process
.TP
.B --zoom <ratio> (Default: 1.0)
Specify the zoom ratio of the HTML file
.TP
.B --hpdi <dpi>, --vpdi <dpi> (Default: 144)
Specify the horizontal and vertical DPI for images
.TP
.B --process-nontext <0|1> (Default: 1)
Whether to process non-text objects (as images)
.TP
.B --single-html <0|1> (Default: 1)
Whether to embed everything into one HTML file.

If switched out, there will be several files generated along with the HTML file including files for fonts, css, images.
.TP
.B --split-pages <0|1> (Default: 0)
If turned on, each page is saved in a separated files, also the generated css file will be store separatedly as if single-html=0

The output files will be named as <output-filename>0.page, <output-filename>1.page, ...
.TP
.B --embed-base-font <0|1> (Default: 1)
Whether to embed base 14 fonts.

There are several base font defined in PDF standards, which are supposed to be provided by the PDF reader.

If this switch is on, local matched font will be used and embedded; otherwise only font names are exported such that web browsers may try to find proper fonts themselves.
.TP
.B --embed-external-font <0|1> (Default: 0)
Similar as above but for non-base fonts.
.TP
.B --decompose-ligature <0|1> (Default: 0)
Decompose ligatures. For example 'fi' -> 'f''i'.
.TP
.B --heps <len>, --veps <len> (Default: 1)
Specify the maximum tolerable horizontal/vertical offset (in pixels).

pdf2htmlEX would try to optimize the generated HTML file moving Text within this distance.
.TP
.B --space-threshold <ratio> (Default: 1.0/6)
pdf2htmlEX would insert a whitespace character ' ' if the distance between two consecutive letters in the same line is wider than ratio * font_size.
.TP
.B --font-size-multiplier <ratio> (Default: 3.0)
Many web browsers limit the minimum font size, and many would round the given font size, which results in incorrect rendering.

Specify a ratio greater than 1 would resolve this issue, however it might freeze some browsers.

For some versions of Firefox, however, there will be a problem when the font size is too large, in which case a smaller value should be specified here.
.TP
.B --auto-hint <0|1> (Default: 0)
If set to 1, hints will be generated for the fonts.

This switch is experimental which may break other things.
.TP
.B --tounicode <-1|0|1> (Default: 0)
A ToUnicode map may be provided for each font in PDF which indicates the 'meaning' of the characters. However often there is better "ToUnicode" info in Type 0/1 fonts, and sometimes the ToUnicode map provided is wrong. 

If this value is set to 1, the ToUnicode Map is always applied, if provided in PDF, and characters may not render correctly in HTML if there are collisions.

If set to -1, a customized map is used such that rendering will be correct in HTML (visually the same), but you may not get correct characters by select & copy & paste.

If set to 0, pdf2htmlEX would try it best to balance the two methods above.
.TP
.B --space-as-offset <0|1> (Default: 0)
Treat space characters as offsets, which may increase the size of the output.

Turn it on if space characters are not displayed correctly, or you want to remove positional spaces.
.TP
.B --css-filename <filename> (Default: "")
Specify the filename of the generated css file, if not embedded.

If it's empty, the file name will be determined automatically.
.TP
.B --font-suffix <suffix> (Default: ".ttf"), --font-format <format> (Default: "truetype")
Specify the suffix and format of fonts extracted from the PDF file. They should be consistent.
.TP
.B --debug <0|1> (Default: 0)
Show debug information.
.TP
.B --clean-tmp <0|1> (Default: 1)
If switched off, intermediate files won't be cleaned in the end.

.SH EXAMPLE
.TP
.B pdf2htmlEX /path/to/file.pdf
