Standard_EXPORT | Graphic2d_Buffer (const Handle(Graphic2d_View)&aView, const Quantity_Length aPivotX, const Quantity_Length aPivotY, const Standard_Integer aWidthIndex=0, const Standard_Integer aColorIndex=0, const Standard_Integer aFontIndex=0, const Aspect_TypeOfDrawMode aDrawMode=Aspect_TODM_REPLACE) |
Creates an empty graphic buffer in the view <aview>. A graphic buffer manages a set of graphic objects and/or primitives. A buffer color and font index can be defined, in place of the default overrideColor or systemFont. When the drawmode is REPLACE the buffer is drawn with the right color and background drawing is used for restoring it at Erase() time. When the drawmode is XOR the buffer is drawn or erase with an optimal color depending of the background color but some side effects can appears depending of background drawing pixels values. . | |
Standard_EXPORT void | Destroy () |
Deletes the graphic buffer <me>. . | |
~Graphic2d_Buffer () | |
Standard_EXPORT void | Add (const Handle(Graphic2d_GraphicObject)&anObject) |
Adds the graphic object <anobject> in the graphic buffer <me>. . | |
Standard_EXPORT void | Add (const Handle(Graphic2d_Primitive)&aPrimitive) |
Adds the primitive <aprimitive> in the graphic buffer <me>. . | |
Standard_EXPORT void | Remove (const Handle(Graphic2d_GraphicObject)&anObject) |
Removes the object <anobject> from the graphic buffer <me>. . | |
Standard_EXPORT void | Remove (const Handle(Graphic2d_Primitive)&aPrimitive) |
Removes the primitive <aprimitive> from the graphic buffer <me>. . | |
Standard_EXPORT void | Clear () |

Standard_EXPORT void | SetAttrib (const Standard_Integer aWidthIndex, const Standard_Integer aColorIndex, const Standard_Integer aFontIndex, const Aspect_TypeOfDrawMode aDrawMode) |
Updates the default buffer color with a new color index defines in the user ColorMap. Update the default buffer font with a new font index defines in the user FontMap. Update the default buffer drawmode with REPLACE or XOR . You can specify the width index - -1 draw all lines with the largest width defined in the buffer <me> - 0 draw all lines with the default width defined in the driver (1 pixel) - draw all lines with the specified width <awidthindex> You can specify the color index - -1 draw all primitives with the color of the first primitive color defined in the buffer. - 0 draw all primitives with the default color. You can specify the font index - -1 draw all text primitives with the font of the first primitive text defined in the buffer. - 0 draw all text primitives with the default font. Warning: The buffer is redisplayed again if it was posted. . | |
