Constructor Detail

PDSingleByteFont

public PDSingleByteFont(COSObject object)

Method Detail

getGlyphsEncoded

public PDGlyphs getGlyphsEncoded(int codepoint)

Description copied from class: PDFont

The PDGlyphs instance for the encoded codepoint.

Specified by:

getGlyphsEncoded in class PDFont

Returns:

The PDGlyphs instance for the encoded codepoint.

getGlyphWidthEncoded

public int getGlyphWidthEncoded(int codepoint)

The glyph width of a codepoint in the font. codepoint refers to the encoded (possibly multibyte) value in the COSString.

In the standard case for single byte encoded fonts, the codepoint is the index in the /Widths array, holding the glyph width.

For multibyte fonts, see PDFontType0.

Specified by:

getGlyphWidthEncoded in class PDFont

Parameters:

codepoint - The codepoint

Returns:

The glyph width of a codepoint in the font

getGlyphWidths

public int[] getGlyphWidths()

The array of glyph widths.

Returns:

The array of glyph widths.

getNextGlyphsEncoded

public PDGlyphs getNextGlyphsEncoded(ByteArrayInputStream is)

Description copied from class: PDFont

The PDGlyphs denoted by the next byte or bytes in the input stream.

For single byte encoded fonts a single byte is read and the associated PDGlyphs is returned. For CID fonts, the appropriate number of bytes is read form the input stream to select the PDGlyphs.

Specified by:

getNextGlyphsEncoded in class PDFont

Parameters:

is - The input stream on the COSString bytes

Returns:

The next PDGlyphs referenced by the input stream.

invalidateCaches

public void invalidateCaches()

Description copied from class: COSBasedObject

Invalidate all local caches as the base object may have changed.

Overrides:

invalidateCaches in class PDFont
