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