/*
* Created on 2010-6-21

* The class for control image
*
* Made by S71ence
*
* @ $img _path picture path
* @ $is _auto_reduce pictures are automatically compressed by size level 1 Yes
* @ $is _appoint whether to manually compress or enlarge 1 yes
* @ $multiple Manually specify the compression/magnification ratio
* @ $is _water_str watermark Text 1 Yes
* @ $water _str watermark Text
* @ $is _watermark watermark Picture 1 Yes
* @ $logo _path watermark Picture Path
* @ $is _display whether to show picture 1 yes
* @ $is _create whether to generate compressed picture 1 Yes
*
Note
* 1. Images cannot be displayed when generating new diagrams, i.e. $isdisplay and $iscreate cannot be set to 1 simultaneously
* 2. When the picture width or height is less than 1000, you need to manually set the compression ratio to compress
* 3. Do not recommend the watermark, to enable, suggest the original picture size preferably within 1000
* 4. The watermark text cannot contain Chinese
* 5. Newly generated images in the original directory file, support n levels
