[ PDF_Font ]

Method

Stores all the specifications for a font style in a font object. Parameters are used with the [PDF_Font] type that define the font face, file, size, color, encoding, and whether to embed it in the PDF. A [PDF_Font] instance stored in a variable is called using the -Font parameter of another [PDF_...] type. The [PDF_Font] must be instantiated before it can be used in another [PDF_...] type.

Parameter Description
-Face Specifies the font by its family name (e.g. "Helvetica"). Required if the -File parameter is not used. Allowed font names are Courier, Courier-Bold, Courier-Oblique, Courier-BoldOblique, Helvetica, Helvetica-Bold, Helvetica-Oblique, Helvetica-BoldOblique, Symbol, Times-Roman, Times-Bold, Times-Italic, Times-BoldItalic, and ZapfDingbats.
-File Creates a font from a local font file. The file name and path to the font must be specified (e.g., '/Fonts/Courier'). Supported font file types are TrueType Font (.ttf) or OpenType Font (.otf).
-Size Sets the font size in points (e.g 14). Required if the -File parameter is not used.
-Color Sets the font color to a [PDF_Color] object or a hex color string (e.g., '#EEEE00'). Defaults to '#000000' if not specified.
-Encoding Sets the desired font encoding for the font (e.g., 'cp1252').
-Embed Embeds the fonts used within the PDF document as opposed to relying on the client PDF reader for font information.

To define a font for a PDF document:

The example belows shows how to use the [PDF_Font] method to define a 14-point red Helvetica font for use in a PDF document. The local #myfont can be used as the value for the -Font parameter of any [PDF_...] method.

Code

local(myfont) = pdf_font(
	-face   = 'Helvetica',
	-size   = 14,
	-color	= '#990000')

local(mypdf) = pdf_doc(
	-file='mypdf.pdf',
	-size='Letter')

local(text) = pdf_text(
	'My first PDF.',
	-paragraph,
	-font=#myfont)

#mypdf->add(#text)
#mypdf = bytes(#mypdf)
file_serve(#mypdf, -file='mypdf.pdf', -type='Content-Type: application/pdf')

Result

A PDF file containing 14-point red Helvetica text "My first PDF." is served to the web browser.
