The GouraudTriangle structure.
const std::string & LibBoard::GouraudTriangle::name | ( | ) | const [virtual] |
Returns the generic name of the shape (e.g., Circle, Rectangle, etc.)
Reimplemented from LibBoard::Polyline.
Point LibBoard::GouraudTriangle::center | ( | ) | const [virtual] |
Returns the gravity center of the shape.
Reimplemented from LibBoard::Polyline.
Rotate the shape around a given center of rotation.
angle | The rotation angle in radian. | |
center | The center of rotation. |
Reimplemented from LibBoard::Polyline.

Shape & LibBoard::GouraudTriangle::rotate | ( | double | angle | ) | [virtual] |
Rotate the shape around its center.
angle | The rotation angle in radian. |
Reimplemented from LibBoard::Polyline.
GouraudTriangle LibBoard::GouraudTriangle::rotated | ( | double | angle | ) | const |
GouraudTriangle LibBoard::GouraudTriangle::translated | ( | double | dx, | |
double | dy | |||
) | const |
Returns a translated copy of the triangle.
dx | The shift along the x axis. | |
dy | The shift along the y axis. |
Reimplemented from LibBoard::Polyline.

GouraudTriangle LibBoard::GouraudTriangle::scaled | ( | double | sx, | |
double | sy | |||
) | const |
Returns a scaled copy of the triangle.
sx | Scale factor along the x axis. | |
sy | Scale factor along the y axis. |
Reimplemented from LibBoard::Polyline.
References LibBoard::Polyline::scale().
void LibBoard::GouraudTriangle::scaleAll | ( | double | s | ) | [virtual] |
Scales all the values (positions, dimensions, etc.) associated with the shape.
s | The scaling factor. |
Reimplemented from LibBoard::Polyline.
void LibBoard::GouraudTriangle::flushPostscript | ( | std::ostream & | stream, | |
const TransformEPS & | transform | |||
) | const [virtual] |
Sends the triangle to a Postscript document.

Reimplemented from LibBoard::Polyline.

void LibBoard::GouraudTriangle::flushFIG | ( | std::ostream & | stream, | |
const TransformFIG & | transform, | |||
std::map< Color, int > & | colormap | |||
) | const [virtual] |
Sends the Triangle to a FIG file format stream.
Warning! Because shading would generally require more colors in the colormap than allowed by the FIG file format, rendering a Gouraud triangle in an XFig file is the same as rendering a simple triangle whose filling color is the average of the vertex colors.
