public abstract class PDCIDFont extends java.lang.Object implements COSObjectable, PDFontLike, PDVectorFont
A CIDFont. A CIDFont is a PDF object that contains information about a CIDFont program. Although its Type value is Font, a CIDFont is not actually a font.It is not usually necessary to use this class directly, prefer
PDType0Font.- Author:

Method Detail

getCOSObject
public COSDictionary getCOSObject()
Description copied from interface:COSObjectableConvert this standard java object to a COS object.- Specified by:
getCOSObjectin interfaceCOSObjectable- Returns:
- The cos object that matches this Java object.
-
getBaseFont
public java.lang.String getBaseFont()
The PostScript name of the font.- Returns:
- The postscript name of the font.
-
getName
public java.lang.String getName()
Description copied from interface:PDFontLikeReturns the name of this font, either the PostScript "BaseName" or the Type 3 "Name".- Specified by:
getNamein interfacePDFontLike
-
getFontDescriptor
public PDFontDescriptor getFontDescriptor()
Description copied from interface:PDFontLikeReturns the font descriptor, may be null.- Specified by:
getFontDescriptorin interfacePDFontLike
-
getFontMatrix
public abstract Matrix getFontMatrix()
Description copied from interface:PDFontLikeReturns the font matrix, which represents the transformation from glyph space to text space.- Specified by:
getFontMatrixin interfacePDFontLike
-
getParent
public final PDType0Font getParent()
Returns the Type 0 font which is the parent of this font.- Returns:
- parent Type 0 font
-
getBoundingBox
public abstract org.apache.fontbox.util.BoundingBox getBoundingBox() throws java.io.IOExceptionDescription copied from interface:PDFontLikeReturns the font's bounding box.- Specified by:
getBoundingBoxin interfacePDFontLike- Throws:
java.io.IOException
-
hasExplicitWidth
public boolean hasExplicitWidth(int code) throws java.io.IOExceptionDescription copied from interface:PDFontLikeReturns true if the Font dictionary specifies an explicit width for the given glyph. This includes Width, W but not default widths entries.- Specified by:
hasExplicitWidthin interfacePDFontLike- Parameters:
code- character code- Throws:
java.io.IOException- if the font could not be read
-
getPositionVector
public Vector getPositionVector(int code)
Description copied from interface:PDFontLikeReturns the position vector (v), in text space, for the given character. This represents the position of vertical origin relative to horizontal origin, for horizontal writing it will always be (0, 0). For vertical writing both x and y are set.- Specified by:
getPositionVectorin interfacePDFontLike- Parameters:
code- character code- Returns:
- position vector
-
getVerticalDisplacementVectorY
public float getVerticalDisplacementVectorY(int code)
Returns the y-component of the vertical displacement vector (w1).- Parameters:
code- character code- Returns:
- w1y
-
getHeight
public abstract float getHeight(int code) throws java.io.IOExceptionDescription copied from interface:PDFontLikeReturns the height of the given character, in glyph space. This can be expensive to calculate. Results are only approximate.Warning: This method is deprecated in PDFBox 2.0 because there is no meaningful value which it can return. The
PDFontLike.getWidth(int)method returns the advance width of a glyph, but there is no corresponding advance height. The logical height of a character is the same for every character in a font, so if you want that, retrieve the font bbox's height. Otherwise if you want the visual bounds of the glyph then call getPath(..) on the appropriate PDFont subclass to retrieve the glyph outline as a GeneralPath.- Specified by:
getHeightin interfacePDFontLike- Parameters:
code- character code- Throws:
java.io.IOException
-
getWidth
public float getWidth(int code) throws java.io.IOExceptionDescription copied from interface:PDFontLikeReturns the advance width of the given character, in glyph space.If you want the visual bounds of the glyph then call getPath(..) on the appropriate PDFont subclass to retrieve the glyph outline as a GeneralPath instead.
- Specified by:
getWidthin interfacePDFontLike- Parameters:
code- character code- Throws:
java.io.IOException
-
getWidthFromFont
public abstract float getWidthFromFont(int code) throws java.io.IOExceptionDescription copied from interface:PDFontLikeReturns the width of a glyph in the embedded font file.- Specified by:
getWidthFromFontin interfacePDFontLike- Parameters:
code- character code- Returns:
- width in glyph space
- Throws:
java.io.IOException- if the font could not be read
-
isEmbedded
public abstract boolean isEmbedded()
Description copied from interface:PDFontLikeReturns true if the font file is embedded in the PDF.- Specified by:
isEmbeddedin interfacePDFontLike
-
getAverageFontWidth
public float getAverageFontWidth()
Description copied from interface:PDFontLikeThis will get the average font width for all characters.- Specified by:
getAverageFontWidthin interfacePDFontLike- Returns:
- The width is in 1000 unit of text space, ie 333 or 777
-
getCIDSystemInfo
public PDCIDSystemInfo getCIDSystemInfo()
Returns the CIDSystemInfo, or null if it is missing (which isn't allowed but could happen).
-
codeToCID
public abstract int codeToCID(int code)
Returns the CID for the given character code. If not found then CID 0 is returned.- Parameters:
code- character code- Returns:
- CID
-
codeToGID
public abstract int codeToGID(int code) throws java.io.IOExceptionReturns the GID for the given character code.- Parameters:
code- character code- Returns:
- GID
- Throws:
java.io.IOException
-
encode
protected abstract byte[] encode(int unicode) throws java.io.IOExceptionEncodes the given Unicode code point for use in a PDF content stream. Content streams use a multi-byte encoding with 1 to 4 bytes.This method is called when embedding text in PDFs and when filling in fields.
- Parameters:
unicode- Unicode code point.- Returns:
- Array of 1 to 4 PDF content stream bytes.
- Throws:
java.io.IOException- If the text could not be encoded.
