Member Function Documentation

getClassTypeId()

static SoType SoHDRImageRW::getClassTypeId ( )

static

Returns the type identifier for this class.

getReadCapability()

virtual SoRasterImageRW::ReadCapability SoHDRImageRW::getReadCapability ( ) const

virtual

Returns if the class can read the specific raster format.

Reimplemented from SoRasterImageRW.

getTypeId()

virtual SoType SoHDRImageRW::getTypeId ( ) const

virtual

Returns the type identifier for this specific instance.

Implements SoRasterImageRW.

getWriteCapability()

virtual SoRasterImageRW::WriteCapability SoHDRImageRW::getWriteCapability ( ) const

virtual

Returns if the class can write in the specific raster format.

Reimplemented from SoRasterImageRW.

isMultipleBufferInverted()

virtual SbBool SoHDRImageRW::isMultipleBufferInverted ( ) const

virtual

Specifies the write method when using multiple buffers.

Returns FALSE if buffers are written from top to bottom. Returns TRUE if buffers are written from bottom to top.

Reimplemented from SoRasterImageRW.

open()

virtual SbBool SoHDRImageRW::open ( SoRasterImageIO *  rasterImageIO, OpenMode  openMode  )

virtual

Opens the reader/writer in the given open mode.

Reimplemented from SoRasterImageRW.

read()

virtual SbBool SoHDRImageRW::read ( SbRasterImage *  rasterImage, SbBool  infoOnly = FALSE  )

virtual

Reads, decodes, and fills the rasterImage parameter.

If infoOnly is TRUE, then the buffer will not be read, the parameter rasterImage will be set with raster size and raster number of components, the buffer will be NULL.

Implements SoRasterImageRW.

write()

virtual SbBool SoHDRImageRW::write ( SbRasterImage *  rasterImage, unsigned int  xPos = 0, unsigned int  yPos = 0  )

virtual

Writes and encodes the given data in the specific format.

If you are using the multiple writing mode, then you can give the offset with (xPos,yPos) you want to write to.

Implements SoRasterImageRW.

writeFooter()

virtual SbBool SoHDRImageRW::writeFooter ( )

virtual

Writes and encodes the footer of this specific format.

Reimplemented from SoRasterImageRW.
