Member Function Documentation

static SoType SoPSImageRW::getClassTypeId (  )  [static]

Returns the type identifier for this class.

Reimplemented from SoRasterImageRW.

SbVec2f SoPSImageRW::getPrintSize (  )  const

Returns the print size given, specified in inches.

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

Returns if the class can read the specific raster format.

Reimplemented from SoRasterImageRW.

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

Returns the type identifier for this specific instance.

Implements SoRasterImageRW.

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

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

Reimplemented from SoRasterImageRW.

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

Specifies the write way 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 SoPSImageRW::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.

void SoPSImageRW::setPrintSize ( const SbVec2f printSize  ) 

Sets the print size for output.

The size is given in inches.

virtual SbBool SoPSImageRW::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.

virtual SbBool SoPSImageRW::writeFooter (  )  [virtual]

Writes and encodes the header of this specific format.

Reimplemented from SoRasterImageRW.
