inBuffer | pointer to jpeg file in memory |
inSize | file of jpeg file in bytes |
memptr | pointer to store RGB data. To enhance performance, the memory must be allocated at least byte. memptr = malloc(1) since subsequent calls will use realloc to allocate memory. The caller is responsible for free(*memptr) eventually. |
memsize | size of RGB data as determined after jpeg decompression |
naxis | 1 for mono, 3 for color |
w | width of image in pixels |
h | height image in pixels |
