示例1: drawComplexText
void Font::drawComplexText(GraphicsContext* context, const TextRun& run, const FloatPoint& point,
int from, int to) const
{
// This glyph buffer holds our glyphs + advances + font data for each glyph.
GlyphBuffer glyphBuffer;
float startX = point.x();
CoreTextController controller(this, run);
controller.advance(from);
float beforeWidth = controller.runWidthSoFar();
controller.advance(to, &glyphBuffer);
// We couldn't generate any glyphs for the run. Give up.
if (glyphBuffer.isEmpty())
return;
float afterWidth = controller.runWidthSoFar();
if (run.rtl()) {
startX += controller.totalWidth() + controller.finalRoundingWidth() - afterWidth;
for (int i = 0, end = glyphBuffer.size() - 1; i < glyphBuffer.size() / 2; ++i, --end)
glyphBuffer.swap(i, end);
} else
startX += beforeWidth;
// Draw the glyph buffer now at the starting point returned in startX.
FloatPoint startPoint(startX, point.y());
drawGlyphBuffer(context, glyphBuffer, run, startPoint);
}示例2: drawSimpleText
void Font::drawSimpleText(GraphicsContext* context, const TextRun& run, const FloatPoint& point, int from, int to) const
{
// This glyph buffer holds our glyphs+advances+font data for each glyph.
GlyphBuffer glyphBuffer;

// Calculate the starting point of the glyphs to be displayed by adding
// all the advances up to the first glyph.
FloatPoint startPoint(startX, point.y());
