// 010 Editor v2.02 Binary Template
//
// File : JpgTemplate.bt
// Author : Mor FTP
// Purpose : Designed for jpg files
// E-Mail : morftp AT hotmail DOT com
// LAST MODIFIED : Nov 3 2014
// This is a detailed JPEG File analysis.
//Features
// 1. Huffmann and quantization tables.
// 2. Exif (APP1) information including jpeg and other thubnail images
// 3. SOS, SOF0, JIFF and APP0 sections
//
// Note : This code doesn't parse all known sections. The reson is the application sections
// contain camera specific information and this information sometimes is not public or
// related to the camera and not important for image display softwares.
//
// New Features: Parses MakerNote for casio qv-r62
//
// 2014-11-03 SweetScape
// * fixed using FTell instead of Ftell
//
// 2012-10-04 dxp
// * added JPEG-LS marker structure.
//
// 2009-03-14 modified by Kuang-che Wu
// * fix parse fail if encounter unknown APP1
// * fix uShort typo
// * parse inlined EXIF data correctly
// * recognize more sections and fields, especially EXIF tags, GPS tags, and CIFF tags
// * and many improvements
