Constructor & Destructor Documentation

◆ SoSGIRGBImageRW()

SoSGIRGBImageRW::SoSGIRGBImageRW ( )

Constructor.

◆ ~SoSGIRGBImageRW()

virtual SoSGIRGBImageRW::~SoSGIRGBImageRW ( )
virtual

Destructor.

Member Function Documentation

◆ getClassTypeId()

static SoType SoSGIRGBImageRW::getClassTypeId ( )
static

Returns the type identifier for this class.


◆ getReadCapability()

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

Returns the read capability of the raster format.

Reimplemented from SoRasterImageRW.

◆ getTypeId()

virtual SoType SoSGIRGBImageRW::getTypeId ( ) const
virtual

Returns the type identifier for this specific instance.

Implements SoRasterImageRW.

◆ getWriteCapability()

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

Returns the write capability of the raster format.

Reimplemented from SoRasterImageRW.

◆ isMultipleBufferInverted()

virtual SbBool SoSGIRGBImageRW::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.

◆ open()

virtual SbBool SoSGIRGBImageRW::open ( SoRasterImageIO rasterImageIO,
OpenMode  openMode 
)
virtual

Opens the reader/writer in the specified open mode.

Reimplemented from SoRasterImageRW.

◆ read()

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

Writes and encodes the given data in this 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 SoSGIRGBImageRW::writeFooter ( )
virtual

Writes and encodes the footer for this specific format.

Reimplemented from SoRasterImageRW.
