Hi Thomas
I think, setting the TextPainter coul dbe another possibility to solve this
problem. My problem doing this way is to find the font parameters (fontname,
size, weight, style, ...). But I'm working...
I try it with the following method, but it isn't working until now:
protected Point2D paintACI(AttributedCharacterIterator aci, Graphics2D
g2d, Point2D loc) {
aci.first();
TextNode.Anchor anchor =
(TextNode.Anchor)aci.getAttribute(GVTAttributedCharacterIterator.TextAttribu
te.ANCHOR_TYPE);
//Adjust position of span
Float xpos =
(Float)aci.getAttribute(GVTAttributedCharacterIterator.TextAttribute.X);
Float ypos =
(Float)aci.getAttribute(GVTAttributedCharacterIterator.TextAttribute.Y);
Float dxpos =
(Float)aci.getAttribute(GVTAttributedCharacterIterator.TextAttribute.DX);
Float dypos =
(Float)aci.getAttribute(GVTAttributedCharacterIterator.TextAttribute.DY);
if (xpos != null) loc.setLocation(xpos.doubleValue(), loc.getY());
if (ypos != null) loc.setLocation(loc.getX(), ypos.doubleValue());
if (dxpos != null) loc.setLocation(loc.getX()+dxpos.doubleValue(),
loc.getY());
if (dypos != null) loc.setLocation(loc.getX(),
loc.getY()+dypos.doubleValue());
//Set up font
List gvtFonts =
(List)aci.getAttribute(GVTAttributedCharacterIterator.TextAttribute.GVT_FONT
_FAMILIES);
Paint forg = (Paint) aci.getAttribute(TextAttribute.FOREGROUND);
Float size = (Float) aci.getAttribute(TextAttribute.SIZE);
if (size == null) {
return loc;
}
//Stroke stroke = $$$
//
(Stroke)aci.getAttribute(GVTAttributedCharacterIterator.TextAttribute.STROKE
);
Float posture = (Float)aci.getAttribute(TextAttribute.POSTURE);
Float taWeight = (Float)aci.getAttribute(TextAttribute.WEIGHT);
if (forg instanceof Color) {
g2d.setColor((Color)forg);
}
g2d.setPaint(forg);
//g2d.setStroke(stroke); $$$
String style = ((posture != null) && (posture.floatValue() > 0.0))
? "italic" : "normal";
String weight = ((taWeight != null) && (taWeight.floatValue() >
1.0))
? "bold" : "normal";
String sFont = "";
Iterator i = gvtFonts.iterator();
//for (Iterator i = gvtFonts.iterator(); i.hasNext(); ) {
GVTFontFamily fam = (GVTFontFamily) i.next();
sFont = fam.getFamilyName();
//}
int fStyle = Font.PLAIN;
if (weight.equals("bold")) {
if (style.equals("italic")) {
fStyle = Font.BOLD | Font.ITALIC;
} else {
fStyle = Font.BOLD;
}
} else {
if (style.equals("italic")) {
fStyle = Font.ITALIC;
} else {
fStyle = Font.PLAIN;
}
}
Font font = new Font(sFont, fStyle, (int) (size.floatValue() +
0.5f));
g2d.setFont(font);
//Get text and paint
String txt = getText(aci);
float advance = StringFormat.getWidth(txt, g2d.getFont());
float tx = 0;
if (anchor != null) {
switch (anchor.getType()) {
case TextNode.Anchor.ANCHOR_MIDDLE:
tx = -advance / 2;
break;
case TextNode.Anchor.ANCHOR_END:
tx = -advance;
}
}
//printAttrs(aci);
g2d.drawString(txt, (float)(loc.getX() + tx), (float)loc.getY());
loc.setLocation(loc.getX()+(double)advance, loc.getY());
return loc;
}
I have copied this method from PDFTextPainter (FOP), but I can't find the
right font! The size, weight and style is OK. Do you know how I can find the
font?
Regards
Hans
