Font

Font(String fontName)

Parameters

fontName: String

Find a font with the specified name, and construct a Font object from it. Otherwise, it makes a font with the default encoding (MacRomanEncoding on Macs, WinAnsiEncoding elsewhere, or for symbol fonts, their own custom encoding). There is not a way to specify another encoding for the font.

When setting text, it checks to see if the text is representable in the font's encoding. If it is not, then DLE makes a "unicode font" with an Identity-H encoding and uses that to set the text. For non-Type0 fonts, this may result in two versions of a font in the output document.

PDFL enforces the following requirements on fonts:

TrueTypes used as CID fonts must be embedded.

All CID fonts that are embedded must be subsetted.

CID fonts that are marked as embedded get their DoNotEmbed flag turned off (or else PDFL won't make a PDEFont from the SysFont).

Font

Font(String fontName, java.util.EnumSet< FontCreateFlags > createFlags)

Parameters

fontName: String

the name of the font to create

createFlags: java.util.EnumSet< FontCreateFlags >

flags specifying embedding and other options for the use of a font in the document

Destructor.

findIndexOfFirstUnrepresentableChar

long findIndexOfFirstUnrepresentableChar(String text)

Parameters

text: String

the text to check

Returns:

long

The index of the first character that cannot be represented in this font.

Find the index of the first character that cannot be represented in this font. This will return the index of the first character in the string for which the font has no glyph. If all characters can be represented (i.e. if IsTextRepresentable() would return true), this will return the length of the string.

getAscent

double getAscent()

Returns:

double

The Ascent value of the font in glyph space units.

the Ascent value from the font descriptor. This is the maximum height above the baseline reached by glyphs in this font, excluding the height of glyphs for accented characters.

getAvgWidth

double getAvgWidth()

Returns:

double

The AvgWidth value of the font in glyph space units, or 0 if not defined.

the AvgWidth value from the font descriptor. This is the average width of glyphs in the font, or 0 if the value is not defined in the font descriptor.

getBBox

Rect getBBox()

Returns:

Rect

The Bounding Box rectangle of the font.

getCapHeight

double getCapHeight()

Returns:

double

The CapHeight value of the font in glyph space units, or 0 if not defined.

the CapHeight value from the font descriptor. This is the vertical coordinate of the top of flat capital letters, measured from the baseline, or 0 if the value is not defined in the font descriptor.

getCidFontType

String getCidFontType()

Returns:

String

getDescent

double getDescent()

Returns:

double

The descent value of the font. \xrefitem pdelayer_apis "PDE Layer" "PDE Layer" PDSysFont PDSysFontGetAttrs \xrefitem pdelayer_apis "PDE Layer" "PDE Layer" PDEFont PDEFontGetAttrs \xrefitem pdlayer_apis "PD Layer" "PD Layer" PDFont PDFontGetMetrics

the Descent value from the font descriptor. This is the maximum depth below the baseline reached by glyphs in this font. The value is a negative number.

getEmbedded

boolean getEmbedded()

Returns:

boolean

Tests that Font is embedded in the document it was created for returns true if the font is embedded and returns false if it is not
