- * Decompression startup: read start of JPEG datastream to see what's there. |

- * compressed data), and will save all tables and parameters in the JPEG |
- * object. It will also initialize the decompression parameters to default |
- * values, and finally return JPEG_HEADER_OK. On return, the application may |
- * adjust the decompression parameters and then call jpeg_start_decompress. |
- * (Or, if the application only wanted to determine the image parameters, |
- * the data need not be decompressed. In that case, call jpeg_abort or |
- * jpeg_destroy to release any temporary space.) |
- * If an abbreviated (tables only) datastream is presented, the routine will |
- * return JPEG_HEADER_TABLES_ONLY upon reaching EOI. The application may then |
- * re-use the JPEG object to read the abbreviated image datastream(s). |
- * It is unnecessary (but OK) to call jpeg_abort in this case. |
- * The JPEG_SUSPENDED return code only occurs if the data source module |
- * requests suspension of the decompressor. In this case the application |
- * should load more source data and then re-call jpeg_read_header to resume |
- * processing. |
- * If a non-suspending data source is used and require_image is TRUE, then the |
- * return code need not be inspected since only JPEG_HEADER_OK is possible. |
