Member Function Documentation

virtual void* OCIO_NAMESPACE::ImageDesc::getAData ( ) const
pure virtual

Get a pointer to the alpha channel of the first pixel or null as alpha channel is optional.

Implemented in OCIO_NAMESPACE::PlanarImageDesc, and OCIO_NAMESPACE::PackedImageDesc.

virtual void* OCIO_NAMESPACE::ImageDesc::getBData ( ) const
pure virtual

Get a pointer to the blue channel of the first pixel.

Implemented in OCIO_NAMESPACE::PlanarImageDesc, and OCIO_NAMESPACE::PackedImageDesc.

virtual BitDepth OCIO_NAMESPACE::ImageDesc::getBitDepth ( ) const
pure virtual

Get the bit-depth.

Implemented in OCIO_NAMESPACE::PlanarImageDesc, and OCIO_NAMESPACE::PackedImageDesc.

virtual void* OCIO_NAMESPACE::ImageDesc::getGData ( ) const
pure virtual

Get a pointer to the green channel of the first pixel.

Implemented in OCIO_NAMESPACE::PlanarImageDesc, and OCIO_NAMESPACE::PackedImageDesc.

virtual long OCIO_NAMESPACE::ImageDesc::getHeight ( ) const
pure virtual

Get the height to process (where y position starts at 0 and ends at height-1).

Implemented in OCIO_NAMESPACE::PlanarImageDesc, and OCIO_NAMESPACE::PackedImageDesc.

virtual void* OCIO_NAMESPACE::ImageDesc::getRData ( ) const
pure virtual

Get a pointer to the red channel of the first pixel.

Implemented in OCIO_NAMESPACE::PlanarImageDesc, and OCIO_NAMESPACE::PackedImageDesc.

virtual long OCIO_NAMESPACE::ImageDesc::getWidth ( ) const
pure virtual

Get the width to process (where x position starts at 0 and ends at width-1).

Implemented in OCIO_NAMESPACE::PlanarImageDesc, and OCIO_NAMESPACE::PackedImageDesc.

virtual ptrdiff_t OCIO_NAMESPACE::ImageDesc::getXStrideBytes ( ) const
pure virtual

Get the step in bytes to find the same color channel of the next pixel.

Implemented in OCIO_NAMESPACE::PlanarImageDesc, and OCIO_NAMESPACE::PackedImageDesc.

virtual ptrdiff_t OCIO_NAMESPACE::ImageDesc::getYStrideBytes ( ) const
pure virtual

Get the step in bytes to find the same color channel of the pixel at the same position in the next line.

Implemented in OCIO_NAMESPACE::PlanarImageDesc, and OCIO_NAMESPACE::PackedImageDesc.

virtual bool OCIO_NAMESPACE::ImageDesc::isFloat ( ) const
pure virtual

Is the image buffer 32-bit float?

Implemented in OCIO_NAMESPACE::PlanarImageDesc, and OCIO_NAMESPACE::PackedImageDesc.

virtual bool OCIO_NAMESPACE::ImageDesc::isRGBAPacked ( ) const
pure virtual

Is the image buffer in packed mode with the 4 color channels? ("Packed" here means that XStrideBytes is 4x the bytes per channel, so it is more specific than simply any PackedImageDesc.)

Implemented in OCIO_NAMESPACE::PlanarImageDesc, and OCIO_NAMESPACE::PackedImageDesc.
