java.lang.Objectorg.apache.fop.pdf.PDFTextUtil
Utility class for generating PDF text objects. It needs to be subclassed to add writing
functionality (see write(String)).
| Field Summary | |
static int |
TR_CLIP
PDF text rendering mode: Add text to path for clipping |
static int |
TR_FILL
PDF text rendering mode: Fill text |
static int |
TR_FILL_CLIP
PDF text rendering mode: Fill text and add to path for clipping |
static int |
TR_FILL_STROKE
PDF text rendering mode: Fill, then stroke text |
static int |
TR_FILL_STROKE_CLIP
PDF text rendering mode: Fill, then stroke text and add to path for clipping |
static int |
TR_INVISIBLE
PDF text rendering mode: Neither fill nor stroke text (invisible) |
static int |
TR_STROKE
PDF text rendering mode: Stroke text |
static int |
TR_STROKE_CLIP
PDF text rendering mode: Stroke text and add to path for clipping |
| Constructor Summary | |
PDFTextUtil()
Main constructor. |
|
| Method Summary | |
void |
adjustGlyphTJ(double adjust)
Writes a glyph adjust value to the "TJ-Buffer". |
void |
beginTextObject()
Called when a new text object should be started. |
void |
concatMatrix(java.awt.geom.AffineTransform at)
Creates a "cm" command. |
void |
endTextObject()
Called when a text object should be ended. |
protected void |
initValues()
Resets the state fields. |
boolean |
isInTextObject()
Indicates whether we are in a text object or not. |
void |
restoreGraphicsState()
Creates a "Q" command, restoring the entire graphics state to its former value by popping it from the stack. |
void |
saveGraphicsState()
Creates a "q" command, pushing a copy of the entire graphics state onto the stack. |
void |
setTextRenderingMode(boolean fill,
boolean stroke,
boolean addToClip)
Sets the text rendering mode. |
void |
setTextRenderingMode(int mode)
Sets the text rendering mode. |
void |
updateTf(java.lang.String fontName,
double fontSize,
boolean multiByte)
Updates the current font. |
protected abstract void |
write(java.lang.String code)
Writes PDF code. |
void |
writeTextMatrix(java.awt.geom.AffineTransform localTransform)
Writes a "Tm" command, setting a new text transformation matrix. |
void |
writeTf(java.lang.String fontName,
double fontSize)
Writes a "Tf" command, setting a new current font. |
void |
writeTJ()
Writes a "TJ" command, writing out the accumulated buffer with the characters and glyph positioning values. |
void |
writeTJMappedChar(char codepoint)
Writes a char to the "TJ-Buffer". |
