C++ (Cpp) Rectf::getUpperLeft Examples

Example #1

File: View.cpp Project: pizthewiz/Cinder-UI

void View::addCenterLines( std::vector<RenderData> &data, const ci::ColorA &color, const ci::Rectf rect, float lineWidth )
{
    vec2 offset = rect.getUpperLeft();
    
    float w = rect.getWidth();
    float h = rect.getHeight();
    
    float hw = w*0.5;
    float hh = h*0.5;
    
    addLine( data, color, offset + vec2(0, hh), offset + vec2(w, hh), lineWidth );
    addLine( data, color, offset + vec2(hw, 0), offset + vec2(hw, h), lineWidth );
}

Example #2

File: View.cpp Project: pizthewiz/Cinder-UI

void View::addPointGrid( std::vector<RenderData> &data, const ci::ColorA &color, const ci::Rectf rect, float gridInterval, float pointSize )
{
    vec2 offset = rect.getUpperLeft();
    
    float w = rect.getWidth();
    float h = rect.getHeight();
    
    float hw = w*0.5;
    float hh = h*0.5;
    
    for( int x = 0; x <= hw; x+=gridInterval )
    {
        for( int y = 0; y <= hh; y+=gridInterval )
        {
            addPoint( data, color, offset + vec2(hw+x, hh+y), pointSize );
            addPoint( data, color, offset + vec2(hw-x, hh+y), pointSize );
            addPoint( data, color, offset + vec2(hw-x, hh-y), pointSize );
            addPoint( data, color, offset + vec2(hw+x, hh-y), pointSize );
        }
    }
