Through non-standard API extensions you can provide a 16 bit data buffer to jpegli. The data is carefully encoded in the dct-coefficients. They are 12 bits so in some situations you can get even 12 bit precision. Quantization errors however sum up and worst case is about 7 bits. Luckily it occurs only in the most noisy environments and in smooth slopes we can get 10.5 bits or so. |
