from_bytes()

std::optional< ImageData > MayaFlux::Kakshya::ImageData::from_bytes ( uint32_t  width, uint32_t  height, uint32_t  channels, ImageFormat  format, std::span< const uint8_t >  bytes  )

static

Build an ImageData from raw pixel bytes in format's layout.

Allocates as allocate() does and copies bytes in.

Returns

The populated ImageData, or nullopt when allocate() would fail or bytes is not exactly width * height * channels elements.

Definition at line 57 of file ImageData.cpp.

{
    auto result = allocate(width, height, channels, format);
    if (!result || result->byte_size() != bytes.size()) {
        return std::nullopt;
    }
 
    std::memcpy(result->data(), bytes.data(), bytes.size());
    return result;
}
