Method Detail

getWidth

float getWidth(int code)

Returns width of glyph for given character code.

Parameters:

code - is code for glyph.

Returns:

width of corresponding glyph or -1 if glyph is not found.

getWidth

float getWidth(String glyphName)

Returns width of glyph for given glyph name.

Parameters:

glyphName - is name for glyph.

Returns:

width of corresponding glyph or -1 if glyph is not found.

parseFont

void parseFont()
        throws IOException

This method does parsing of font, after it all the data needed should be extracted.

Throws:

IOException - if error in font parsing occurs.

containsCode

boolean containsCode(int code)

Checks if font contains character with given code.

Parameters:

code - is character code.

Returns:

true if font contains character with given code.

containsCID

boolean containsCID(int cid)

Method works only for fonts where cid notation is used.

Returns:

true if font a is cid font and contains given cid.

containsGlyph

boolean containsGlyph(String glyphName)

Checks if this font program has glyph for given glyph name.

Parameters:

glyphName - is the name of glyph.

Returns:

true if this font program has glyph for given name.

isAttemptedParsing

boolean isAttemptedParsing()

Returns:

true if font parsing has been attempted.

isSuccessfulParsing

boolean isSuccessfulParsing()

Returns:

true if font was successfully parsed.

getGlyphName

String getGlyphName(int code)

Returns glyph name for glyph with given code.

Parameters:

code - is code of glyph.

Returns:

glyph name.

getFontProgramResource

ASFileStreamCloser getFontProgramResource()

Returns:

file stream closer that handles the closing of font program stream or null if stream is memory stream.
