.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.
|
|
|
|
.SH OPTIONS
|
|
|
|
.SS Pages
|
|
|
|
.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
|
|
|
|
.SS Dimensions
|
|
|
|
.B --zoom <ratio>, --fit-width <width>, --fit-height <height>
|
|
--zoom specifies the zoom factor directly; --fit-width/height specifies the maximum width/height of a page, the values are in pixels.
|
|
|
|
If multiple values are specified, the minimum one will be used.
|
|
|
|
If none is specified, pages will be rendered as 72DPI.
|
|
|
|
.TP
|
|
.B --use-cropbox <0|1> (Default: 0)
|
|
Use CropBox instead of MediaBox for output.
|
|
|
|
.TP
|
|
.B --hdpi <dpi>, --vdpi <dpi> (Default: 144)
|
|
Specify the horizontal and vertical DPI for images
|
|
|
|
|
|
.SS Output
|
|
|
|
.TP
|
|
.B --single-html <0|1> (Default: 1)
|
|
Whether to embed everything into one HTML file.
|
|
|
|
If switched off, there will be several files generated along with the HTML file including files for fonts, css, images.
|
|
|
|
Note that the outline will always be embedded into the main HTML file no matter if this switch is on or not.
|
|
And only when this switch is off will there be a separate .outline file contains the outline.
|
|
You need to modify the manifest if you do not want outline embedded.
|
|
|
|
.TP
|
|
.B --split-pages <0|1> (Default: 0)
|
|
If turned on, the pages, css, and outline will be stored into separated files and no consolidated <output-filename>.html will be generated.
|
|
|
|
<output-filename> may be used to specify the format for the filenames for individual pages. <output-filename> may contain a %d placeholder to indicate where the page number should be placed. The placeholder supports a limited subset of normal numerical placeholders, including specified width and zero padding.
|
|
|
|
If <output-filename> does not contain a placeholder for the page number, the page number will be inserted directly before the file extension. If the filename does not have an extension, the page number will be placed at the end of the file name.
|
|
|
|
If <output-filename> is not specified, <input-filename> will be used for the output filename, replacing the extension with .page and adding the page number directly before the extension.
|
|
|
|
This switch is useful if you want pages to be loaded separately & dynamically -- in which case you need to compose the page yourself, and a supporting backend might be necessary.
|
|
|
|

|
|
|
|
.TP
|
|
.B --stretch-narrow-glyph <0|1> (Default: 0)
|
|
If set to 1, glyphs narrower than described in PDF will be stretched; otherwise space will be padded to the right of the glyphs

|
|
.TP

.SS Text
|
|
|
|
.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: 0.125)
|
|
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: 4.0)
|
|
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 --space-as-offset <0|1> (Default: 0)
|
|
If set to 1, space characters will be treated as offsets, which allows a better optimization.
|
|
|
|
For PDF files with bad encodings, turning on this option may cause losing characters.
|
|
|
|
.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 its best to balance the two methods above.
|
|
|
|
.TP
|
|
.B --optimize-text <0|1> (Deafult: 1)
|
|
If set to 1, pdf2htmlEX will try to reduce the number of HTML elements used for text. Turn it off if anything goes wrong.

.SH MANIFEST and DATA-DIR
|
|
When split-pages is 0, the manifest file describes how the final html page should be generated.
|
|
|
|
By default, pdf2htmlEX will use the manifest in the default data-dir (run `pdf2htmlEX -v` to check), which gives a simple demo of its syntax.
|
|
|
|
You can modify the default one, or you can create a new one and specify the correct data-dir in the command line.
|
|
|
|
When single-html is 1, all files referred by the manifest must be located in the data-dir.
|
|
|
|
