示例1: make_pair
std::pair<float, float> SVGGlyphToPathTranslator::extents()
{
AffineTransform glyphPathTransform = transform();
FloatPoint beginning = glyphPathTransform.mapPoint(m_currentPoint);
FloatSize end = glyphPathTransform.mapSize(FloatSize(m_glyphBuffer.advanceAt(m_index)));
return std::make_pair(beginning.x(), beginning.x() + end.width());
}示例2: transformPaintInvalidationRect
LayoutRect SVGLayoutSupport::transformPaintInvalidationRect(
const LayoutObject& object,
const AffineTransform& rootTransform,
const FloatRect& localRect) {
FloatRect adjustedRect = rootTransform.mapRect(localRect);
if (object.isSVGShape() && object.styleRef().svgStyle().hasStroke()) {
if (float strokeWidthForHairlinePadding =
toLayoutSVGShape(object).strokeWidth()) {
// For hairline strokes (stroke-width < 1 in device space), Skia
// rasterizes up to 0.4(9) off the stroke center. That means
// enclosingIntRect is not enough - we must also pad to 0.5.
// This is still fragile as it misses out on CC/DSF CTM components.
const FloatSize strokeSize = rootTransform.mapSize(FloatSize(
strokeWidthForHairlinePadding, strokeWidthForHairlinePadding));
if (strokeSize.width() < 1 || strokeSize.height() < 1) {
float pad =
0.5f - std::min(strokeSize.width(), strokeSize.height()) / 2;
DCHECK_GT(pad, 0);
// Additionally, square/round caps can potentially introduce an outset
// <= 0.5
if (object.styleRef().svgStyle().capStyle() != ButtCap)
pad += 0.5f;
adjustedRect.inflate(pad);
}
}
}
if (adjustedRect.isEmpty())
return LayoutRect();
// Use enclosingIntRect because we cannot properly apply subpixel offset of
// the SVGRoot since we don't know the desired subpixel accumulation at this
// point.
return LayoutRect(enclosingIntRect(adjustedRect));

std::pair<float, float> CairoGlyphToPathTranslator::extents()
{
FloatPoint beginning = m_translation.mapPoint(FloatPoint());
FloatSize end = m_translation.mapSize(m_glyphBuffer.advanceAt(m_index));
