◆ SoTIFFImageRW()

SoTIFFImageRW::SoTIFFImageRW ( )

Constructor.

◆ ~SoTIFFImageRW()

virtual SoTIFFImageRW::~SoTIFFImageRW ( )
virtual

Destructor.

Member Function Documentation

◆ getClassTypeId()

static SoType SoTIFFImageRW::getClassTypeId ( )
static

Returns the type identifier for this class.


◆ getCompressionMode()

SoTIFFImageRW::CompressionMode SoTIFFImageRW::getCompressionMode ( ) const

Gets the compression mode used for encoding.

◆ getTypeId()

virtual SoType SoTIFFImageRW::getTypeId ( ) const
virtual

Returns the type identifier for this specific instance.

Implements SoRasterImageRW.

◆ open()

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

Opens the reader/writer in the specified open mode.

Returns true if successful.

Reimplemented from SoRasterImageRW.

◆ read()

virtual SbBool SoTIFFImageRW::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.

◆ readRegion()

virtual SbBool SoTIFFImageRW::readRegion ( SbRasterImage rasterImage,
const SbBox2i32 region 
)
virtual

Read the specified region of current open image into rasterImage.

Returns true if successful. Call the open() method before calling this method.

After calling this method successfully, the size of the SbRasterImage is the requested region size. The requested region may extend outside the source image. In this case, undefined pixels are set to zero. The region may be as small as a single pixel, e.g. (1,1,1,1), but xmin must be <= xmax and ymin <= ymax.

Warning
This implementation read full image and after copy the desired region.

Reimplemented from SoRasterImageRW.

◆ setCompressionMode()

void SoTIFFImageRW::setCompressionMode ( SoTIFFImageRW::CompressionMode  compressionMode)

Sets the compression mode to use when encoding the image.

Default compression is PACKBITS_COMPRESSION.

◆ write()

virtual SbBool SoTIFFImageRW::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 specify the offset (with xPos,yPos) you want to write to.

Implements SoRasterImageRW.
