Member Function Documentation

beginEditing()

virtual void OdTrVisTexture::beginEditing ( )

pure virtual

Sometimes image have to be preprocessed befor we can call setColor or setScanline (Palette or compressed images, for example)

endEditing()

virtual void OdTrVisTexture::endEditing ( )

pure virtual

format()

virtual Format OdTrVisTexture::format ( ) const

pure virtual

getColor()

virtual void OdTrVisTexture::getColor ( OdUInt32  nX, OdUInt32  nY, TextureColor &  color  ) const

pure virtual

getDataAlignment()

OdUInt32 OdTrVisTexture::getDataAlignment ( ) const

inline

Definition at line 103 of file TrVisTexture.h.

getMaxValues()

virtual TextureColor OdTrVisTexture::getMaxValues ( ) const

pure virtual

Since different format may have different color value intervals (0-255, 0.f - 1.f) we need this function to obtain maxs

getScanline()

virtual void OdTrVisTexture::getScanline ( OdUInt32  startLine, OdUInt32  linesCount, TextureColor *  pScanline  ) const

inlinevirtual

Definition at line 120 of file TrVisTexture.h.

static

This function converts TextureColors from one format to another (OdUInt8-based to float-based, etc) using TextureColorContext

pure virtual

setPalette()

virtual void OdTrVisTexture::setPalette ( OdTrVisTexture *  pTexture )
