示例1: BrushBegin
void LineBrush::BrushBegin( const Point source, const Point target )
{
ImpressionistDoc* pDoc = GetDocument();
ImpressionistUI* dlg=pDoc->m_pUI;
int lineWidth = pDoc->getLineWidth();
glLineWidth((GLfloat) lineWidth);
pDoc->setLastPoint( source );
BrushMove( source, target );
}示例2: BrushMove
void LineBrush::BrushMove( const Point source, const Point target )
{
ImpressionistDoc* pDoc = GetDocument();
ImpressionistUI* dlg=pDoc->m_pUI;
if ( pDoc == NULL ) {
printf( "LineBrush::BrushMove document is NULL\n" );
return;
}
int length;
int angleSelection;
float angle;
Point lastPoint;
//Define the length and figure out how we are determining the brush angle
length = pDoc->getSize();
angleSelection = pDoc->getAngleRadio();
//If the brush angle selection is based off of cursor direction, do this
if (angleSelection == 2)
{
lastPoint = pDoc->getLastPoint();
angle = atan(float(lastPoint.y - source.y)/(lastPoint.x - source.x)) + M_PI/2.;
}
else
angle = pDoc->getBrushAngle() * (M_PI/180.);
//Create the lines
glBegin( GL_LINES );
SetColor( source );
glVertex2d( source.x, source.y );
glVertex2d( source.x + cos(angle) * length, source.y + sin(angle) * length);
glEnd();
