Functions

• size_t BitsPerPixel (const fuchsia::images::PixelFormat & pixel_format)

  Returns the number of bits per pixel for the given format. This is the bits

  per pixel in the overall image across all bytes that contain pixel data. For

  example, NV12 is 12 bits per pixel.

• size_t StrideBytesPerWidthPixel (const fuchsia::images::PixelFormat & pixel_format)

  This is the number of stride bytes per pixel of width. For formats such as

  NV12 that separate Y and UV data, this is the number of stride bytes of the Y

  plane. NV12 has the same stride for the UV data. formats with a different

  stride for UV data vs Y data are not handled yet.

• size_t MaxSampleAlignment (const fuchsia::images::PixelFormat & pixel_format)

  Returns the pixel alignment for the given format.

  This is technically something closer to "max sample alignment" for the given

  format. For example, NV12 returns 2 here because its UV interleaved data has

  2 bytes per sample, despite its Y plane having 1 byte per sample.

  The stride is required to be divisible by this alignment.

• size_t ImageSize (const fuchsia::images::ImageInfo & image_info)

  This would be height * stride, if it weren't for formats like NV12, where it

  isn't. The output is bytes.
