Member Function Documentation
| static SoType SoPGXImageRW::getClassTypeId | ( | ) | [static] |
Returns the type identifier for this class.
Reimplemented from SoRasterImageRW.
| virtual SoRasterImageRW::ReadCapability SoPGXImageRW::getReadCapability | ( | ) | const [virtual] |
Returns the read capability of this format.
Reimplemented from SoRasterImageRW.
| virtual SoType SoPGXImageRW::getTypeId | ( | ) | const [virtual] |
Returns the type identifier for this specific instance.
Implements SoRasterImageRW.
| virtual SoRasterImageRW::WriteCapability SoPGXImageRW::getWriteCapability | ( | ) | const [virtual] |
Returns the write capability of this format.
Reimplemented from SoRasterImageRW.
| virtual SbBool SoPGXImageRW::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 SoPGXImageRW::open | ( | SoRasterImageIO * | rasterImageIO, | |
| OpenMode | openMode | |||
| ) | [virtual] |
Opens the reader/writer in the specified open mode.
Returns true if successful.
Reimplemented from SoRasterImageRW.
| virtual SbBool SoPGXImageRW::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 SoPGXImageRW::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.
