Graphic2d_FramedText (const Handle< Graphic2d_GraphicObject > &aGraphicObject, const TCollection_ExtendedString &aText, const Standard_Real X, const Standard_Real Y, const Quantity_PlaneAngle anAngle=0.0, const Quantity_Ratio aMargin=0.1, const Aspect_TypeOfText aType=Aspect_TOT_SOLID, const Quantity_Factor aScale=1.0) | |
Creates a framed text in a graphic object <aGraphicObject> The text is <aText>. The reference point is <X>, <Y>. The orientation angle is <anAngle>. The margin ratio is <aMargin>,defines the proportional margin between the text height and the outline frame. The type of text is <aType> and must be one of : Aspect_TOT_SOLID, Aspect_TOT_OUTLINE, The scale factor apply to the original font size, Angles are measured counterclockwise with 0 radian at 3 o'clock. Warning: a text can be orientable,slantable,zoomable or outlinable only when this options are enable regardless of the graphic driver. i.e: Xw driver does not,but Xdps or PS driver does. | |
void | SetFrameColorIndex (const Standard_Integer anIndex=0) |
Sets the color index for the frame of the text <me>. default color is 0 (the same color that the text). | |
void | SetFrameWidthIndex (const Standard_Integer anIndex=0) |
Sets the width index for the frame of the text <me>. default width is 0 (1 pixel out line frame is drawn). | |
virtual Standard_Boolean | Fit (const Quantity_Length aWidth, const Quantity_Length aHeight, const Standard_Boolean Adjust=Standard_True, const Standard_Boolean Expand=Standard_True) |
Defines the size of the text according to a bounding box. If Adjust corresponds to TRUE, text positioning depends on the text origin and bottom line. The method returns Standard_True if the current Driver is compatible with the text size. Warning Fit computation is executed only if the dimension is > 0. | |
virtual Standard_Boolean | Trunc (const Quantity_Length aWidth) |
Trunc the text when the Width of the text is greater that the defined Width Max, and returns Standard_True if the current Driver used is enable to trunc the text size. | |
virtual Standard_Boolean | TextSize (Quantity_Length &aWidth, Quantity_Length &aHeight, Quantity_Length &anXoffset, Quantity_Length &anYoffset) const |
Returns Standard_True if the current Driver used is enabled to get the right size and framed text offsets in the world size parameter <aWidth>,<aHeight>,<anXoffset>,<anYoffset> depending of the attributes of the text and the current scale of the view. NOTE that the text offsets defines the relative position of the of the text string origin from the lower left corner of the framed text boundary limits. | |
Quantity_Ratio | Margin () const |
Returns the text margin. | |
Standard_Integer | FrameColorIndex () const |
Returns the text frame color index. | |
Standard_Integer | FrameWidthIndex () const |
Returns the text frame width index. | |

virtual void | Draw (const Handle< Graphic2d_Drawer > &aDrawer) |
Draws the framed text <me>. | |
virtual Standard_Boolean | Pick (const Standard_ShortReal X, const Standard_ShortReal Y, const Standard_ShortReal aPrecision, const Handle< Graphic2d_Drawer > &aDrawer) |
Returns Standard_True if the framed text <me> is picked, Standard_False if not. |
