Graphic3d_MarkerImage (const Handle< TColStd_HArray1OfByte > &theBitMap, const Standard_Integer theWidth, const Standard_Integer theHeight) | |
Creates marker image from array of bytes (method for compatibility with old markers definition). More... | |

Return marker image. If an instance of the class has been initialized with a bitmap, it will be converted to image. More... | |
const 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() More... | |
const TCollection_AsciiString & | GetImageId () const |
Return an unique ID. This ID will be used to manage resource in graphic driver. More... | |
const TCollection_AsciiString & | GetImageAlphaId () const |
Return an unique ID. This ID will be used to manage resource in graphic driver. More... | |
void | GetTextureSize (Standard_Integer &theWidth, Standard_Integer &theHeight) const |
Return texture size. More... | |
bool | IsColoredImage () const |
Return TRUE if marker image has colors (e.g. RGBA and not grayscale). More... | |
