113 * THE BIG PICTURE:
114 *
115 * The rough outline this JPEG decompression operation is:
116 *
117 * allocate and initialize JPEG decompression object
118 * specify data source (eg, a file)
119 * jpeg_read_header(); // obtain image dimensions and other parameters
120 * set parameters for decompression
121 * jpeg_start_decompress();
122 * while (scan lines remain to be read)
123 * jpeg_read_scanlines(...);
124 * jpeg_finish_decompress();
125 * release JPEG decompression object
