PdfFontType3
Class: PdfFontType3
Represents a Type3 font in a PDF document.
Type 3 fonts differ from the other fonts supported by PDF. In Type 3 fonts, glyphs are defined by streams of PDF graphics operators. These streams are associated with character names. Note! PdfFontType3 does not support the PdfFont#createNativeFont method, it returns null.

Accessors
baseFont
Get Signature
get baseFont(): string;
Gets or sets the PostScript name of the font.
Returns
string
Set Signature
set baseFont(value): void;
Gets or sets the PostScript name of the font.
Parameters
value
string
Returns
void
Inherited from
id
Get Signature
get id(): number;
Gets the reference to the object.
Returns
number
Inherited from
isEmbedded
Get Signature
get isEmbedded(): boolean;
Gets a value indicating whether the font is embedded.
Returns
boolean
Inherited from
om
Get Signature
get om(): ObjectManager;
Gets the owner ObjectManager instance.
Returns
Inherited from
Methods
createNativeFont()
createNativeFont(): Font;
Gets a Font object created from the embedded font data.
Note that this method will return null if the font is not embedded or does not support this operation (e.g. Type3 fonts).
Returns
The Font object.
Inherited from
PdfFontSimple.createNativeFont
findNativeFont()
findNativeFont(doc, allowStandardPdfFonts?): Font;
Finds the most suitable native font for rendering text associated with this PDF font.
The PDF specification does not define a precise algorithm for selecting a font when no embedded font data is available. This method uses a combination of heuristics and practical strategies to choose an appropriate native font.
Parameters
doc
The PdfDocument that owns this font.
allowStandardPdfFonts?
boolean
If true (the default), also searches the 14 standard PDF fonts if a suitable font could not be found among the registered fonts.
Returns
The native font that matches the current PDF font, or null if a match could not be found.
Inherited from
free()
free(): void;
Detaches the object from the ObjectManager and deallocates its memory, if possible.
Returns
void
Inherited from
getEmbeddedData()
getEmbeddedData(): Uint8Array<ArrayBufferLike>;
Returns the embedded font data, returns null if the font is not embedded.
Returns
Uint8Array<ArrayBufferLike>
The embedded font data or null if the font is not embedded.
Inherited from
getFontAttributes()
getFontAttributes(): PdfFontAttributes;
Extracts the attributes of the current font. If a specific attribute cannot be determined, the corresponding value is set to null.
Returns
The PdfFontAttributes object containing the font attributes.
Inherited from
PdfFontSimple.getFontAttributes
getFontDescriptor()
getFontDescriptor(): PdfFontDescriptor;
Gets a PdfFontDescriptor object that describes the font.
Returns
The PdfFontDescriptor object.
Inherited from
PdfFontSimple.getFontDescriptor
rebind()
rebind(omTo): void;
Rebinds the object from the current ObjectManager to the specified one.
Parameters
omTo
The new ObjectManager for the object.
Returns
void
Inherited from
removeEmbeddedData()
removeEmbeddedData(doc): void;
Removes the embedded font data.
Please note that a PDF may display incorrectly after removing an embedded font's data. Use with caution.
Parameters
doc
The document that owns the font.
Returns
void
Inherited from
PdfFontSimple.removeEmbeddedData
tryGetPdfCode()
tryGetPdfCode(unicode): PdfCodeInfo;
Tries to convert a Unicode value to the character's PDF code.
Note that this method can fail if the font does not contain the necessary info for the conversion or does not contain the specified Unicode value, in this case null is returned.
Note also that this method can be slow as it uses large font tables like /Encoding, /ToUnicode etc., so it is recommended that the returned results are cached by the caller.
Parameters
unicode
string
The character Unicode.
Returns
The PdfCodeInfo object containing the character PDF code, or null if the conversion failed.
Inherited from
tryGetUnicode()
tryGetUnicode(pdfCode): string;
Converts a character's PDF code to its Unicode value.
Note that this method can fail if the font does not contain the necessary info for the conversion, in this case null is returned.
Note also that this method can be slow as it uses large font tables like /Encoding, /ToUnicode etc., so the returned results better be cached by the caller.
Parameters
pdfCode
number
The character PDF code.
Returns
string
The character Unicode, or null if the conversion failed.
