Member Function Documentation

static SoType SoGIFImageRW::getClassTypeId (  )  [static]

Returns the type identifier for this class.

Reimplemented from SoRasterImageRW.

virtual SoRasterImageRW::ReadCapability SoGIFImageRW::getReadCapability (  )  const [virtual]

Returns the read capability of the raster format.

Reimplemented from SoRasterImageRW.

virtual SoType SoGIFImageRW::getTypeId (  )  const [virtual]

Returns the type identifier for this specific instance.

Implements SoRasterImageRW.

virtual SoRasterImageRW::WriteCapability SoGIFImageRW::getWriteCapability (  )  const [virtual]

Returns the write capability of the raster format.

Reimplemented from SoRasterImageRW.

virtual SbBool SoGIFImageRW::isMultipleBufferInverted (  )  const [virtual]

Specifies the write direction 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.

virtual SbBool SoGIFImageRW::open ( SoRasterImageIO rasterImageIO,
OpenMode  openMode 
) [virtual]

Opens the reader/writer in the specified open mode.

Reimplemented from SoRasterImageRW.

virtual SbBool SoGIFImageRW::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.

virtual SbBool SoGIFImageRW::write ( SbRasterImage rasterImage,
unsigned int  xPos = 0,
unsigned int  yPos = 0 
) [virtual]

Writes and encodes the given data in the specific format.


Not currently supported for this format.

Implements SoRasterImageRW.
