Enumeration Type Documentation

ChannelDatatype

enum class rerun::datatypes::ChannelDatatype : uint8_t

strong

Datatype: The innermost datatype of an image.

How individual color channel components are encoded.

Enumerator
U8	8-bit unsigned integer.
I8	8-bit signed integer.
U16	16-bit unsigned integer.
I16	16-bit signed integer.
U32	32-bit unsigned integer.
I32	32-bit signed integer.
U64	64-bit unsigned integer.
I64	64-bit signed integer.
F16	16-bit IEEE-754 floating point, also known as half.
F32	32-bit IEEE-754 floating point, also known as float or single.
F64	64-bit IEEE-754 floating point, also known as double.

ColorModel

enum class rerun::datatypes::ColorModel : uint8_t

strong

Datatype: Specified what color components are present in an archetypes::Image.

This combined with datatypes::ChannelDatatype determines the pixel format of an image.

Enumerator
L	Grayscale luminance intencity/brightness/value, sometimes called Y
RGB	Red, Green, Blue.
RGBA	Red, Green, Blue, Alpha.
BGR	Blue, Green, Red.
BGRA	Blue, Green, Red, Alpha.

PixelFormat

enum class rerun::datatypes::PixelFormat : uint8_t

strong

Datatype: Specifieds a particular format of an archetypes::Image.

Most images can be described by a datatypes::ColorModel and a datatypes::ChannelDatatype, e.g. RGB and U8 respectively.

However, some image formats has chroma downsampling and/or use differing number of bits per channel, and that is what this datatypes::PixelFormat is for.

All these formats support random access.

For more compressed image formats, see archetypes::EncodedImage.

Enumerator
Y_U_V12_LimitedRange	Y_U_V12 is a YUV 4:2:0 fully planar YUV format without chroma downsampling, also known as I420. This uses limited range YUV, i.e. Y is expected to be within [16, 235] and U/V within [16, 240]. First comes entire image in Y in one plane, followed by the U and V planes, which each only have half the resolution of the Y plane.
NV12	NV12 (aka Y_UV12) is a YUV 4:2:0 chroma downsampled form at with 12 bits per pixel and 8 bits per channel. This uses limited range YUV, i.e. Y is expected to be within [16, 235] and U/V within [16, 240]. First comes entire image in Y in one plane, followed by a plane with interleaved lines ordered as U0, V0, U1, V1, etc.
YUY2	YUY2 (aka YUYV, YUYV16 or NV21), is a YUV 4:2:2 chroma downsampled format with 16 bits per pixel and 8 bits per channel. This uses limited range YUV, i.e. Y is expected to be within [16, 235] and U/V within [16, 240]. The order of the channels is Y0, U0, Y1, V0, all in the same plane.
Y8_FullRange	Monochrome Y plane only, essentially a YUV 4:0:0 planar format. Also known as just "gray". This is virtually identical to a 8bit luminance/grayscale (see `datatypes::ColorModel`). This uses entire range YUV, i.e. Y is expected to be within [0, 255]. (as opposed to "limited range" YUV as used e.g. in NV12).
Y_U_V24_LimitedRange	Y_U_V24 is a YUV 4:4:4 fully planar YUV format without chroma downsampling, also known as I444. This uses limited range YUV, i.e. Y is expected to be within [16, 235] and U/V within [16, 240]. First comes entire image in Y in one plane, followed by the U and V planes.
Y_U_V24_FullRange	Y_U_V24 is a YUV 4:4:4 fully planar YUV format without chroma downsampling, also known as I444. This uses full range YUV with all components ranging from 0 to 255 (as opposed to "limited range" YUV as used e.g. in NV12). First comes entire image in Y in one plane, followed by the U and V planes.
Y8_LimitedRange	Monochrome Y plane only, essentially a YUV 4:0:0 planar format. Also known as just "gray". This uses limited range YUV, i.e. Y is expected to be within [16, 235]. If not for this range limitation/remapping, this is almost identical to 8bit luminace/grayscale (see `datatypes::ColorModel`).
Y_U_V12_FullRange	Y_U_V12 is a YUV 4:2:0 fully planar YUV format without chroma downsampling, also known as I420. This uses full range YUV with all components ranging from 0 to 255 (as opposed to "limited range" YUV as used e.g. in NV12). First comes entire image in Y in one plane, followed by the U and V planes, which each only have half the resolution of the Y plane.
Y_U_V16_LimitedRange	Y_U_V16 is a YUV 4:2:2 fully planar YUV format without chroma downsampling, also known as I422. This uses limited range YUV, i.e. Y is expected to be within [16, 235] and U/V within [16, 240]. First comes entire image in Y in one plane, followed by the U and V planes, which each only have half the horizontal resolution of the Y plane.
Y_U_V16_FullRange	Y_U_V16 is a YUV 4:2:2 fully planar YUV format without chroma downsampling, also known as I422. This uses full range YUV with all components ranging from 0 to 255 (as opposed to "limited range" YUV as used e.g. in NV12). First comes entire image in Y in one plane, followed by the U and V planes, which each only have half the horizontal resolution of the Y plane.
