Module yuva_pixmap_info

Enums

• DataType
• PlaneConfig
• Subsampling
  UV subsampling is also specified in the enum value names using J:a:b notation (e.g. 4:2:0 is 1/2 horizontal and 1/2 vertical resolution for U and V). If alpha is present it is not sub- sampled. Note that Subsampling values other than k444 are only valid with PlaneConfig values that have U and V in different planes than Y (and A, if present).

Functions

• default_color_type_for_data_type
  Gets the default ColorType to use with num_channels channels, each represented as DataType. Returns ColorType::Unknown if no such color type.
• num_channels_and_data_type
  If the ColorType is supported for YUVA pixmaps this will return the number of YUVA channels that can be stored in a plane of this color type and what the DataType is of those channels. If the ColorType is not supported as a YUVA plane the number of channels is reported as 0 and the DataType returned should be ignored.
