C++ (Cpp) marginIntervals Examples

Example #1

File: RasterShape.cpp Project: kodybrown/webkit

void RasterShape::getExcludedIntervals(LayoutUnit logicalTop, LayoutUnit logicalHeight, SegmentList& result) const
{
    const RasterShapeIntervals& intervals = marginIntervals();
    if (intervals.isEmpty())
        return;

    IntShapeIntervals excludedIntervals;
    intervals.getExcludedIntervals(logicalTop, logicalTop + logicalHeight, excludedIntervals);
    appendLineSegments(excludedIntervals, result);
}

Example #2

void RasterShape::getExcludedIntervals(LayoutUnit logicalTop, LayoutUnit logicalHeight, SegmentList& result) const
{
    const RasterShapeIntervals& intervals = marginIntervals();
    if (intervals.isEmpty())
        return;

    float y1 = logicalTop;
    float y2 = logicalTop + logicalHeight;

    if (y2 < intervals.bounds().y() || y1 >= intervals.bounds().maxY())
        return;

    intervals.getExcludedIntervals(y1, y2, result);
}

Example #3

File: RasterShape.cpp Project: Drakey83/steamlink-sdk

void RasterShape::getExcludedIntervals(LayoutUnit logicalTop, LayoutUnit logicalHeight, SegmentList& result) const
{
    const RasterShapeIntervals& intervals = marginIntervals();
    if (intervals.isEmpty())
        return;

    int y1 = logicalTop;
    int y2 = logicalTop + logicalHeight;
    ASSERT(y2 >= y1);
    if (y2 < intervals.bounds().y() || y1 >= intervals.bounds().maxY())
        return;

    y1 = std::max(y1, intervals.bounds().y());
    y2 = std::min(y2, intervals.bounds().maxY());
    IntShapeInterval excludedInterval;

    for (int y = y1; y < y2;  y++)
        excludedInterval.unite(intervals.intervalAt(y));

    // Note: |marginIntervals()| returns end-point exclusive
    // intervals. |excludedInterval.x2()| contains the left-most pixel
    // offset to the right of the calculated union.
    result.append(LineSegment(excludedInterval.x1(), excludedInterval.x2()));
