C++ (Cpp) releasePaintingResource Examples

Example #1

void SVGInlineTextBox::paintDecorationWithStyle(GraphicsContext* context, ETextDecoration decoration, const SVGTextFragment& fragment, RenderObject* decorationRenderer)
{
    ASSERT(!m_paintingResource);
    ASSERT(m_paintingResourceMode != ApplyToDefaultMode);

    RenderStyle* decorationStyle = decorationRenderer->style();
    ASSERT(decorationStyle);

    const Font& font = decorationStyle->font();
    const FontMetrics& fontMetrics = font.fontMetrics();

    // The initial y value refers to overline position.
    float thickness = thicknessForDecoration(decoration, font);

    if (fragment.width <= 0 && thickness <= 0)
        return;

    float y = fragment.y - fontMetrics.ascent() + positionOffsetForDecoration(decoration, fontMetrics, thickness);

    Path path;
    path.addRect(FloatRect(fragment.x, y, fragment.width, thickness));

    context->save();

    if (acquirePaintingResource(context, decorationRenderer, decorationStyle))
        releasePaintingResource(context, &path);

    context->restore();
}

Example #2

{
    releasePaintingResource(context, /* path */0);

#if ENABLE(SVG_FONTS)
    textRun.setActivePaintingResource(0);
#endif
}
