Public Member Functions | |
Standard_EXPORT | Graphic2d_ImageFile (const Handle(Graphic2d_GraphicObject)&aGraphicObject, OSD_File &aFile, const Quantity_Length X, const Quantity_Length Y, const Quantity_Length adx=0.0, const Quantity_Length ady=0.0, const Aspect_CardinalPoints aTypeOfPlacement=Aspect_CP_Center, const Quantity_Factor aScale=1.0) |
Defines an image with its center location; <x>, <y> defines the position in the space model. <adx>, <ady> defines an offset in the device space. <ascale> defines a scale factor applied to the original size of the image. The image will be placed at this offset according to the type of placement. . | |
Standard_EXPORT void | SetCenter (const Quantity_Length X, const Quantity_Length Y) |
Modifies the center location of the image <me>. . | |
Standard_EXPORT void | SetOffset (const Quantity_Length dx, const Quantity_Length dy) |
Modifies the offset of the image <me>. . | |
Standard_EXPORT void | SetPlacement (const Aspect_CardinalPoints aPlacement) |
Modifies the type of placement of the image <me>. . | |
Standard_EXPORT void | Translate (const Quantity_Length DX, const Quantity_Length DY) |
Modifies the center location of the image <me> by translating it. . | |
Standard_EXPORT void | SetScale (const Quantity_Factor aScale) |
Changes the scale factor of the image. . | |
Standard_EXPORT void | SetZoomable (const Standard_Boolean aFlag=Standard_False) |
The image <me> follows the scale factor of the view if the flag is Standard_True. . | |
Standard_EXPORT void | Clear () |
Clear the reference to this imagefile if something inside have changed,Forced the reload of this at Draw() time. . | |
Standard_EXPORT Quantity_Factor | Scale () const |
Returns the original scale factor applied to the image <me>. . | |
Standard_EXPORT Standard_Boolean | IsZoomable () const |
Returns Standard_True if the image <me> follows the scale factor of the view. . | |
Standard_EXPORT void | Position (Quantity_Length &X, Quantity_Length &Y) const |
returns the position in the space model | |
Standard_EXPORT void | Offset (Quantity_Length &aX, Quantity_Length &aY) const |
returns the offset in the device space | |
Standard_EXPORT Aspect_CardinalPoints | Placement () const |
returns the type of placement | |
Standard_EXPORT OSD_File | ImageFile () const |

Static Public Member Functions | |
static Standard_EXPORT Standard_Boolean | Values (OSD_File &aFile, Standard_Integer &aWidth, Standard_Integer &aHeight, Standard_Integer &aDepth) |
Returns Standard_True, the Image pixel size and the Image planes depth, if the image file : - is not open - exists - have the extension .xwd NOTE that only XWD image file type are recognized. . | |
static Standard_EXPORT void | SwapLong (const Standard_Address anAddress, const Standard_Integer aNumOfBytes) |
Swaps long ints . | |
Protected Member Functions | |
Standard_EXPORT void | Draw (const Handle(Graphic2d_Drawer)&aDrawer) |
Draws the image at the required center location defined by the SetCenter method. . | |
Standard_EXPORT 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 image <me> is picked, Standard_False if not. . | |
