Public Attributes | |
uint32_t | num_channels |
JxlDataType | data_type |
JxlEndianness | endianness |
size_t | align |
Data type for the sample values per channel per pixel for the output buffer for pixels. This is not necessarily the same as the data type encoded in the codestream. The channels are interleaved per pixel. The pixels are organized row by row, left to right, top to bottom. TODO(lode): implement padding / alignment (row stride) TODO(lode): support different channel orders if needed (RGB, BGR, ...)
size_t JxlPixelFormat::align |
Align scanlines to a multiple of align bytes, or 0 to require no alignment at all (which has the same effect as value 1)
JxlDataType JxlPixelFormat::data_type |
Data type of each channel.
JxlEndianness JxlPixelFormat::endianness |
Whether multi-byte data types are represented in big endian or little endian format. This applies to JXL_TYPE_UINT16, JXL_TYPE_UINT32 and JXL_TYPE_FLOAT.
uint32_t JxlPixelFormat::num_channels |
Amount of channels available in a pixel buffer. 1: single-channel data, e.g. grayscale or a single extra channel 2: single-channel + alpha 3: trichromatic, e.g. RGB 4: trichromatic + alpha TODO(lode): this needs finetuning. It is not yet defined how the user chooses output color space. CMYK+alpha needs 5 channels.
