Constructor Details

#initialize(orientation = 'P', unit = 'mm', format = 'A4', unicode = true, encoding = "UTF-8", diskcache = false) ⇒ RBPDF

This is the class constructor. It allows to set up the page format, the orientation and the measure unit used in all the methods (except for the font sizes).

@since 1.0
@param string :orientation

page orientation. Possible values are (case insensitive):

  • P or Portrait (default)

  • L or Landscape

@param string :unit

User measure unit. Possible values are:

  • pt: point

  • mm: millimeter (default)

  • cm: centimeter

  • in: inch

A point equals 1/72 of inch, that is to say about 0.35 mm (an inch being 2.54 cm). This is a very common unit in typography; font sizes are expressed in that unit.

@param mixed :format

The format used for pages. It can be either: A string indicating the page format:

  • 4A0,2A0,A0,A1,A2,A3,A4 (default),A5,A6,A7,A8,A9,A10

  • B0,B1,B2,B3,B4,B5,B6,B7,B8,B9,B10

  • C0,C1,C2,C3,C4,C5,C6,C7,C8,C9,C10

  • RA0,RA1,RA2,RA3,RA4

  • SRA0,SRA1,SRA2,SRA3,SRA4

  • LETTER,LEGAL,EXECUTIVE,FOLIO

An array containing page measures and advanced options: see setPageFormat()

@param boolean :unicode

TRUE means that the input text is unicode (default = true)

@param String :encoding

charset encoding; default is UTF-8

@param boolean :diskcache

if TRUE reduce the RAM memory usage by caching temporary data on filesystem (slower).

Instance Method Details

#AcceptPageBreak ⇒ Object Also known as: accept_page_break

Whenever a page break condition is met, the method is called, and the break is issued or not depending on the returned value. The default implementation returns a value according to the mode selected by SetAutoPageBreak(). This method is called automatically and should not be called directly by the application.

#AddFont(family, style = '', fontfile = '', subset = nil) ⇒ Object Also known as: add_font

Imports a TrueType, Type1, core, or CID0 font and makes it available. It is necessary to generate a font definition file first with the makefont.rb utility. The definition file (and the font file itself when embedding) must be present either in the current directory or in the one indicated by FPDF_FONTPATH if the constant is defined. If it could not be found, the error “Could not include font definition file” is generated.

Example

:pdf.add_font('Comic','I')
# is equivalent to:
:pdf.add_font('Comic','I','comici.rb')
@param string :family

Font family. The name can be chosen arbitrarily. If it is a standard family name, it will override the corresponding font.

@param string :style

Font style. Possible values are (case insensitive):

  • empty string: regular (default)

  • B: bold

  • I: italic

  • BI or IB: bold italic

@param string :fontfile

The font definition file. By default, the name is built from the family and style, in lower case with no space.

@return array

containing the font data, or false in case of error.

@param boolean :subset

if true embedd only a subset of the font (stores only the information related to the used characters); this option is valid only for TrueTypeUnicode fonts. If you want to enable users to change the document, set this parameter to false. If you subset the font, the person who receives your PDF would need to have your same font in order to make changes to your PDF. The file size of the PDF would also be smaller because you are embedding only part of a font.

#AddPage(orientation = '', format = '', keepmargins = false, tocpage = false) ⇒ Object Also known as: add_page

Adds a new page to the document. If a page is already present, the Footer() method is called first to output the footer (if enabled). Then the page is added, the current position set to the top-left corner according to the left and top margins (or top-right if in RTL mode), and Header() is called to display the header (if enabled). The origin of the coordinate system is at the top-left corner (or top-right for RTL) and increasing ordinates go downwards.

@param string :orientation

page orientation. Possible values are (case insensitive):

  • P or PORTRAIT (default)

  • L or LANDSCAPE

@param mixed :format

The format used for pages. It can be either: A string indicating the page format:

  • 4A0,2A0,A0,A1,A2,A3,A4 (default),A5,A6,A7,A8,A9,A10

  • B0,B1,B2,B3,B4,B5,B6,B7,B8,B9,B10

  • C0,C1,C2,C3,C4,C5,C6,C7,C8,C9,C10

  • RA0,RA1,RA2,RA3,RA4

  • SRA0,SRA1,SRA2,SRA3,SRA4

  • LETTER,LEGAL,EXECUTIVE,FOLIO

An array containing page measures and advanced options: see setPageFormat()

@param boolean :keepmargins

if true overwrites the default page margins with the current margin

@param boolean :tocpage

if true set the tocpage state to true (the added page will be used to display Table Of Content).

Prints a cell (rectangular area) with optional borders, background color and character string. The upper-left corner of the cell corresponds to the current position. The text can be aligned or centered. After the call, the current position moves to the right or to the next line. It is possible to put a link on the text. If automatic page breaking is enabled and the cell goes beyond the limit, a page break is done before outputting.

@param float :w

Cell width. If 0, the cell extends up to the right margin.

@param float :h

Cell height. Default value: 0.

@param string :txt

String to print. Default value: empty string.

@param mixed :border

Indicates if borders must be drawn around the cell. The value can be either a number:

  • 0: no border (default)

  • 1: frame

or a string containing some or all of the following characters (in any order):

  • L: left

  • T: top

  • R: right

  • B: bottom

@param int :ln

Indicates where the current position should go after the call. Possible values are:

  • 0: to the right

  • 1: to the beginning of the next line

  • 2: below

Putting 1 is equivalent to putting 0 and calling Ln() just after. Default value: 0.

@param string :align

Allows to center or align the text. Possible values are:

  • L or empty string: left align (default value)

  • C: center

  • R: right align

@param int :fill

Indicates if the cell background must be painted (1) or transparent (0). Default value: 0.

@param mixed :link

URL or identifier returned by AddLink().

@param int :stretch

stretch carachter mode:

  • 0 = disabled

  • 1 = horizontal scaling only if necessary

  • 2 = forced horizontal scaling

  • 3 = character spacing only if necessary

  • 4 = forced character spacing

@param boolean :ignore_min_height

if true ignore automatic minimum height value.

@param string :calign

cell vertical alignment relative to the specified Y value. Possible values are:

  • T : cell top

  • C : center

  • B : cell bottom

  • A : font top

  • L : font baseline

  • D : font bottom

@param string :valign

text vertical alignment inside the cell. Possible values are:

  • T : top

  • M : middle

  • B : bottom

@param array :col2

second color (lower right corner) (RGB components).

@param array :col3

third color (upper right corner) (RGB components).

@param array :col4

fourth color (upper left corner) (RGB components).

@param array :coords

<ul><li>for one patch mesh: array(float x1, float y1, .… float x12, float y12): 12 pairs of coordinates (normally from 0 to 1) which specify the Bezier control points that define the patch. First pair is the lower left edge point, next is its right control point (control point 2). Then the other points are defined in the order: control point 1, edge point, control point 2 going counter-clockwise around the patch. Last (x12, y12) is the first edge point’s left control point (control point 1).</li><li>for two or more patch meshes: array[number of patches]: arrays with the following keys for each patch: f: where to put that patch (0 = first patch, 1, 2, 3 = right, top and left of precedent patch - I didn’t figure this out completely - just try and error ;-) points: 12 pairs of coordinates of the Bezier control points as above for the first patch, 8 pairs of coordinates for the following patches, ignoring the coordinates already defined by the precedent patch (I also didn’t figure out the order of these - also: try and see what’s happening) colors: must be 4 colors for the first patch, 2 colors for the following patches</li></ul>

@param array :coords_min

minimum value used by the coordinates. If a coordinate’s value is smaller than this it will be cut to coords_min. default: 0

@param array :coords_max

maximum value used by the coordinates. If a coordinate’s value is greater than this it will be cut to coords_max. default: 1

@param boolean :antialias

A flag indicating whether to filter the shading function to prevent aliasing artifacts.

This method return the estimated needed height for print a simple text string in Multicell() method. Generally, if you want to know the exact height for a block of content you can use the following technique:

# store current object
pdf.start_transaction()
# store starting values
start_y = pdf.get_y()
start_page = pdf.get_page()
# call your printing functions with your parameters
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

# - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
# get the new Y
end_y = pdf.get_y()
end_page = pdf.get_page()
# calculate height
height = 0
if end_page == start_page
  height = end_y - start_y

    end
  end
end
# restore previous object
pdf = pdf.rollbackTransaction()

Puts an image in the page. The upper-left corner must be given. The dimensions can be specified in different ways:

  • explicit width and height (expressed in user unit)

  • one explicit dimension, the other being calculated automatically in order to keep the original proportions

  • no explicit dimension, in which case the image is put at 72 dpi

Supported formats are PNG images whitout RMagick/MiniMagick library and JPEG and GIF and WebP images supported by RMagick/MiniMagick. For JPEG, all flavors are allowed:

  • gray scales

  • true colors (24 bits)

  • CMYK (32 bits)

For PNG, are allowed:

  • gray scales on at most 8 bits (256 levels)

  • indexed colors

  • true colors (24 bits)

If a transparent color is defined, it will be taken into account (but will be only interpreted by Acrobat 4 and above). The format can be specified explicitly or inferred from the file extension. It is possible to put a link on the image.

  • Remark: if an image is used several times, only one copy will be embedded in the file.

@param string :file

Name of the file containing the image.

@param float :x

Abscissa of the upper-left corner.

@param float :y

Ordinate of the upper-left corner.

@param float :w

Width of the image in the page. If not specified or equal to zero, it is automatically calculated.

@param float :h

Height of the image in the page. If not specified or equal to zero, it is automatically calculated.

@param string :type

Image format. Possible values are (case insensitive): JPG, JPEG, PNG, GIF, WebP. If not specified, the type is inferred from the file extension.

@param mixed :link

URL or identifier returned by AddLink().

@param string :align

Indicates the alignment of the pointer next to image insertion relative to image height. The value can be:

  • T: top-right for LTR or top-left for RTL

  • M: middle-right for LTR or middle-left for RTL

  • B: bottom-right for LTR or bottom-left for RTL

  • N: next line

@param mixed :resize

If true resize (reduce) the image to fit :w and :h (requires RMagick/MiniMagick library); if false do not resize; if 2 force resize in all cases (upscaling and downscaling).

@param int :dpi

dot-per-inch resolution used on resize

@param string :palign

Allows to center or align the image on the current line. Possible values are:

  • L : left align

  • C : center

  • R : right align

  • ” : empty string : left for LTR or right for RTL

@param boolean :ismask

true if this image is a mask, false otherwise

@param mixed :imgmask

image object returned by this function or false

@param mixed :border

Indicates if borders must be drawn around the image. The value can be either a number:

  • 0: no border (default)

  • 1: frame

or a string containing some or all of the following characters (in any order):

  • L: left

  • T: top

  • R: right

  • B: bottom

@param boolean :fitbox

If true scale image dimensions proportionally to fit within the (:w, :h) box.

@param boolean :hidden

if true do not display the image.

@param boolean :fitonpage

if true the image is resized to not exceed page dimensions.

This method allows printing text with line breaks. They can be automatic (as soon as the text reaches the right border of the cell) or explicit (via the n character). As many cells as necessary are output, one below the other. Text can be aligned, centered or justified. The cell block can be framed and the background painted.

@param float :w

Width of cells. If 0, they extend up to the right margin of the page.

@param float :h

Cell minimum height. The cell extends automatically if needed.

@param string :txt

String to print

@param mixed :border

Indicates if borders must be drawn around the cell block. The value can be either a number:

  • 0: no border (default)

  • 1: frame

or a string containing some or all of the following characters (in any order):

  • L: left

  • T: top

  • R: right

  • B: bottom

@param string :align

Allows to center or align the text. Possible values are:

  • L or empty string: left align

  • C: center

  • R: right align

  • J: justification (default value when :ishtml=false)

@param int :fill

Indicates if the cell background must be painted (1) or transparent (0). Default value: 0.

@param int :ln

Indicates where the current position should go after the call. Possible values are:

  • 0: to the right

  • 1: to the beginning of the next line [DEFAULT]

  • 2: below

@param float :x

x position in user units

@param float :y

y position in user units

@param boolean :reseth

if true reset the last cell height (default true).

@param int :stretch

stretch carachter mode:

  • 0 = disabled

  • 1 = horizontal scaling only if necessary

  • 2 = forced horizontal scaling

  • 3 = character spacing only if necessary

  • 4 = forced character spacing

@param boolean :ishtml

set to true if :txt is HTML content (default = false).

@param boolean :autopadding

if true, uses internal padding and automatically adjust it to account for line width.

@param float :maxh

maximum height. It should be >= :h and less then remaining space to the bottom of the page, or 0 for disable this feature. This feature works only when :ishtml=false.

@return int

Rerurn the number of cells or 1 for html mode.

#Output(name = '', dest = '') ⇒ Object Also known as: output

Send the document to a given destination: string, local file or browser. In the last case, the plug-in may be used (if present) or a download (“Save as” dialog box) may be forced. The method first calls Close() if necessary to terminate the document.

@param string :name

The name of the file when saved. Note that special characters are removed and blanks characters are replaced with the underscore character.

@param string :dest

Destination where to send the document. It can take one of the following values:

  • I: send the file inline to the browser (default). The plug-in is used if available. The name given by name is used when one selects the “Save as” option on the link generating the PDF.

  • D: send to the browser and force a file download with the name given by name.

  • F: save to a local server file with the name given by name.

  • S: return the document as a string. name is ignored.

  • FI: equivalent to F + I option

  • FD: equivalent to F + D option

#SetFont(family, style = '', size = 0, fontfile = '', subset = nil) ⇒ Object Also known as: set_font

Sets the font used to print character strings. The font can be either a standard one or a font added via the AddFont() method. Standard fonts use Windows encoding cp1252 (Western Europe). The method can be called before the first page is created and the font is retained from page to page. If you just wish to change the current font size, it is simpler to call SetFontSize().

  • Note: for the standard fonts, the font metric files must be accessible. There are three possibilities for this:

    • They are in the current directory (the one where the running script lies)

    • They are in one of the directories defined by the include_path parameter

    • They are in the directory defined by the FPDF_FONTPATH constant

@param string :family

Family font. It can be either a name defined by AddFont() or one of the standard Type1 families (case insensitive):

  • times (Times-Roman)

  • timesb (Times-Bold)

  • timesi (Times-Italic)

  • timesbi (Times-BoldItalic)

  • helvetica (Helvetica)

  • helveticab (Helvetica-Bold)

  • helveticai (Helvetica-Oblique)

  • helveticabi (Helvetica-BoldOblique)

  • courier (Courier)

  • courierb (Courier-Bold)

  • courieri (Courier-Oblique)

  • courierbi (Courier-BoldOblique)

  • symbol (Symbol)

  • zapfdingbats (ZapfDingbats)

It is also possible to pass an empty string. In that case, the current family is retained.

@param string :style

Font style. Possible values are (case insensitive):

  • empty string: regular

  • B: bold

  • I: italic

  • U: underline

  • D: line trough

  • O: overline

or any combination. The default value is regular. Bold and italic styles do not apply to Symbol and ZapfDingbats basic fonts or other fonts when not defined.

@param float :size

Font size in points. The default value is the current size. If no size has been specified since the beginning of the document, the value taken is 12

@param string :fontfile

The font definition file. By default, the name is built from the family and style, in lower case with no spaces.

@param boolean :subset

if true embedd only a subset of the font (stores only the information related to the used characters); this option is valid only for TrueTypeUnicode fonts. If you want to enable users to change the document, set this parameter to false. If you subset the font, the person who receives your PDF would need to have your same font in order to make changes to your PDF. The file size of the PDF would also be smaller because you are embedding only part of a font.

#writeHTMLCell(w, h, x, y, html = '', border = 0, ln = 0, fill = 0, reseth = true, align = '', autopadding = true) ⇒ Object Also known as: write_html_cell

Prints a cell (rectangular area) with optional borders, background color and html text string. The upper-left corner of the cell corresponds to the current position. After the call, the current position moves to the right or to the next line. If automatic page breaking is enabled and the cell goes beyond the limit, a page break is done before outputting.

@param float :w

Cell width. If 0, the cell extends up to the right margin.

@param float :h

Cell minimum height. The cell extends automatically if needed.

@param float :x

upper-left corner X coordinate

@param float :y

upper-left corner Y coordinate

@param string :html

html text to print. Default value: empty string.

@param mixed :border

Indicates if borders must be drawn around the cell. The value can be either a number:

  • 0: no border (default)

  • 1: frame

or a string containing some or all of the following characters (in any order):

  • L: left

  • T: top

  • R: right

  • B: bottom

@param int :ln

Indicates where the current position should go after the call. Possible values are:

  • 0: to the right (or left for RTL language)

  • 1: to the beginning of the next line

  • 2: below

Putting 1 is equivalent to putting 0 and calling Ln() just after. Default value: 0.

@param int :fill

Indicates if the cell background must be painted (1) or transparent (0). Default value: 0.

@param boolean :reseth

if true reset the last cell height (default true).

@param string :align

Allows to center or align the text. Possible values are:

  • L : left align

  • C : center

  • R : right align

  • ” : empty string : left for LTR or right for RTL

@param boolean :autopadding

if true, uses internal padding and automatically adjust it to account for line width.
