“Quite OK Image” Ada/SPARK implementation

This is based on QOI format specification V1.

To call the Encode/Decode procedure you have to provide a large enough output buffer. If the provided output buffer is not large enough, each procedure will return with an Output_Size of zero. For Encode the minimum size for the output buffer is given by the Encode_Worst_Case function based on the dimensions of the image and the number of channels. For Decode you should use the Get_Desc procedure to get the image specification and then the exact output size will be Desc.Width * Desc.Height * Desc.Channels.
