QVector< Vector2D > | pointSet (double offsetAngle=0.0) const |
Returns a point set. The points are sampled along the pixel's ellipses w.r.t the relative angle which is added to the text line orientation. If angle == DBL_MAX or pixel->stats() == NULL, the ellipse centers are sampled instead. More... | |

Public Member Functions inherited from rdf::BaseElement | |
BaseElement (const QString &id=QString()) | |
This class keeps an ID to keep track of transformed elements during a processing chain. You can e.g. generate Pixel elements from MserBlobs. After filtering, processing etc. you can map back to the (pixel accurate) MserBlob using this ID. More... | |
void | setId (const QString &id) |
Sets the (preferably unique) ID. If no ID is set, a unqiue ID is generated and assigned. More... | |
QString | id () const |
Returns the elment's id. More... | |

Protected Member Functions inherited from rdf::PixelSet | |
Polygon | polygon (const QVector< Vector2D > &pts) const |
Returns a poly line along the points defined by angle. If maxAngleThr != -1, points are rejected if the cosine of their enclosing angle is smaller than maxAngleThr. e.g. maxAngleThr = 0 would allow polygon changes of up to 90°. More... | |
