| | Graphic3d_MarkerImage (const occ::handle< Image_PixMap > &theImage, const occ::handle< Image_PixMap > &theImageAlpha=occ::handle< Image_PixMap >()) |
| | Constructor from existing pixmap.
|
| | Graphic3d_MarkerImage (const occ::handle< NCollection_HArray1< uint8_t > > &theBitMap, const int theWidth, const int theHeight) |
| | Creates marker image from array of bytes (method for compatibility with old markers definition).
|
| const occ::handle< Image_PixMap > & | GetImage () |
| | Return marker image. If an instance of the class has been initialized with a bitmap, it will be converted to image.
|
| const occ::handle< Image_PixMap > & | GetImageAlpha () |
| | Return image alpha as grayscale image. Note that if an instance of the class has been initialized with a bitmap or with grayscale image this method will return exactly the same image as GetImage().
|
| const TCollection_AsciiString & | GetImageId () const |
| | Return an unique ID. This ID will be used to manage resource in graphic driver.
|
| const TCollection_AsciiString & | GetImageAlphaId () const |
| | Return an unique ID. This ID will be used to manage resource in graphic driver.
|
| void | GetTextureSize (int &theWidth, int &theHeight) const |
| | Return texture size.
|
| bool | IsColoredImage () const |
| | Return TRUE if marker image has colors (e.g. RGBA and not grayscale).
|
| occ::handle< NCollection_HArray1< uint8_t > > | GetBitMapArray (const double theAlphaValue=0.5, const bool theIsTopDown=false) const |
| | Return marker image as array of bytes. If an instance of the class has been initialized with image, it will be converted to bitmap based on the parameter theAlphaValue.
|
| Public Member Functions inherited from Standard_Transient |
| | Standard_Transient () |
| | Empty constructor.
|
| | Standard_Transient (const Standard_Transient &) |
| | Copy constructor – does nothing.
|
| Standard_Transient & | operator= (const Standard_Transient &) |
| | Assignment operator, needed to avoid copying reference counter.
|
| virtual | ~Standard_Transient ()=default |
| | Destructor must be virtual.
|
| virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
| | Returns a type descriptor about this object.
|
| bool | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
| | Returns a true value if this is an instance of Type.
|
| bool | IsInstance (const char *const theTypeName) const |
| | Returns a true value if this is an instance of TypeName.
|
| bool | IsKind (const opencascade::handle< Standard_Type > &theType) const |
| | Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
|
| bool | IsKind (const char *const theTypeName) const |
| | Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
|
| Standard_Transient * | This () const |
| | Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
|
| int | GetRefCount () const noexcept |
| | Get the reference counter of this object.
|
| void | IncrementRefCounter () noexcept |
| | Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
|
| int | DecrementRefCounter () noexcept |
| | Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.
|
| virtual void | Delete () const |
| | Memory deallocator for transient classes.
|
This class is used to store bitmaps and images for markers rendering. It can convert bitmap texture stored in NCollection_HArray1<uint8_t> to Image_PixMap and vice versa.
