示例1: drawBidiText
void GraphicsContext::drawBidiText(const FontCascade& font, const TextRun& run, const FloatPoint& point, FontCascade::CustomFontNotReadyAction customFontNotReadyAction)
{
if (paintingDisabled())
return;
BidiResolver<TextRunIterator, BidiCharacterRun> bidiResolver;
bidiResolver.setStatus(BidiStatus(run.direction(), run.directionalOverride()));
bidiResolver.setPositionIgnoringNestedIsolates(TextRunIterator(&run, 0));
// FIXME: This ownership should be reversed. We should pass BidiRunList
// to BidiResolver in createBidiRunsForLine.
BidiRunList<BidiCharacterRun>& bidiRuns = bidiResolver.runs();
bidiResolver.createBidiRunsForLine(TextRunIterator(&run, run.length()));
if (!bidiRuns.runCount())
return;
FloatPoint currPoint = point;
BidiCharacterRun* bidiRun = bidiRuns.firstRun();
while (bidiRun) {
TextRun subrun = run.subRun(bidiRun->start(), bidiRun->stop() - bidiRun->start());
bool isRTL = bidiRun->level() % 2;
subrun.setDirection(isRTL ? RTL : LTR);
subrun.setDirectionalOverride(bidiRun->dirOverride(false));
float width = font.drawText(*this, subrun, currPoint, 0, -1, customFontNotReadyAction);
currPoint.move(width, 0);
bidiRun = bidiRun->next();
}
bidiRuns.deleteRuns();
}示例2: drawText
float GraphicsContext::drawText(const FontCascade& font, const TextRun& run, const FloatPoint& point, int from, int to)
{
if (paintingDisabled())
return 0;
return font.drawText(*this, run, point, from, to);
