http://www.umpcfever.com/viewthread.php?tid=4409

win7的工具還滿好用的，可以說是一步到位了

另外格式化的動作可使用內建工具，可參考 http://maketecheasier.com/boot-and-install-windows-7-from-usb-flash-drive/2009/01/23

擷取PDF檔內圖片

使用軟體的話，有以下工具

http://opensecrets.pixnet.net/blog/post/27841494

http://azo-freeware.blogspot.com/2008/08/some-pdf-image-extract-14.html

使用linux/perl的話，參考下列連結

http://stackoverflow.com/questions/490629/how-can-i-extract-images-from-a-pdf-file

使用手寫程式的話，如果是jpg檔，以這個python script而言很簡單

http://nedbatchelder.com/blog/200712/extracting_jpgs_from_pdfs.html

否則就要參考一些資料了

http://stackoverflow.com/questions/2693820/extract-images-from-pdf-without-resampling-in-python

http://www.jpedal.org/PDFblog/2010/04/understanding-the-pdf-file-format-how-are-images-stored/

這也證實了，如果不是單純的jpg圖檔的話，"擷取PDF檔內圖片"這件工作可能會很麻煩

涉及中文的話，可參考以下連結

perl將ascii轉成utf-8的方法

似乎每隔一陣子就會遇到，參考 http://perldoc.perl.org/utf8.html



    use utf8;
    no utf8;
    # Convert the internal representation of a Perl scalar to/from UTF-8.
    $num_octets = utf8::upgrade($string);
    $success    = utf8::downgrade($string[, FAIL_OK]);
    # Change each character of a Perl scalar to/from a series of
    # characters that represent the UTF-8 bytes of each original character.
    utf8::encode($string);  # "\x{100}"  becomes "\xc4\x80"
    utf8::decode($string);  # "\xc4\x80" becomes "\x{100}"
    $flag = utf8::is_utf8(STRING); # since Perl 5.8.1
    $flag = utf8::valid(STRING);
