Member Function Documentation

getClassTypeId()

static SoType SoPSImageRW::getClassTypeId ( )

static

Returns the type identifier for this class.

getPrintSize()

SbVec2f SoPSImageRW::getPrintSize

(

)

const

Returns the print size given, specified in inches.

getReadCapability()

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

virtual

Returns if the class can read the specific raster format.

Reimplemented from SoRasterImageRW.

getTypeId()

virtual SoType SoPSImageRW::getTypeId ( ) const

virtual

Returns the type identifier for this specific instance.

Implements SoRasterImageRW.

getWriteCapability()

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

virtual

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

Reimplemented from SoRasterImageRW.

isMultipleBufferInverted()

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.

read()

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.

setPrintSize()

void SoPSImageRW::setPrintSize

(

const SbVec2f &

printSize

)

Sets the print size for output.

The size is given in inches.

write()

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.

writeFooter()

virtual SbBool SoPSImageRW::writeFooter ( )

virtual

Writes and encodes the header of this specific format.

Reimplemented from SoRasterImageRW.
