Constructor & Destructor Documentation

EQ_API eq::PixelData::PixelData

(

)

Construct new pixel data.

Version

1.0

EQ_API eq::PixelData::~PixelData

(

)

Destruct the pixel data.

Version

1.0

Member Function Documentation

void eq::PixelData::reset

Member Data Documentation

pression::CompressorResult eq::PixelData::compressedData

The compressed pixel data blocks.

Version

1.9.1

Definition at line 88 of file pixelData.h.

uint32_t eq::PixelData::compressorFlags

Flags used for compression.

Version

1.0

Definition at line 93 of file pixelData.h.

uint32_t eq::PixelData::compressorName

The compressor used to produce compressedData.

Version

1.0

Definition at line 91 of file pixelData.h.

uint32_t eq::PixelData::externalFormat

The type of data stored in pixels in main memory.

the output token types in plugins/compressor.h

Version

1.0

Definition at line 62 of file pixelData.h.

uint32_t eq::PixelData::internalFormat

The type of data stored in FrameBuffer or texture on the GPU.

See Also

the input token types in plugins/compressor.h

Version

1.0

Definition at line 55 of file pixelData.h.

void* eq::PixelData::pixels

uncompressed pixel data, pvp * pixelSize bytes.

Version

1.0

Definition at line 85 of file pixelData.h.

uint32_t eq::PixelData::pixelSize

The size of one pixel, in bytes, stored in pixels.

See Also

the output token types in plugins/compressor.h

Version

1.0

Definition at line 69 of file pixelData.h.

PixelViewport eq::PixelData::pvp

The dimensions of the pixel data in pixels.

Note that this pvp might differ from the image pvp since the data is downloaded from the GPU using a plugin, which might compress the data. If unmodified pixel data is required, the correct download plugin has to be used.
