/*
* Created on 2010-6-21
*
* The class for control image
*
* Made by s71ence
*
* @ $ Img_path: Image path
* @ $ Is_auto_reduce: whether the image is automatically compressed according to the size level. 1 is
* @ $ Is_appoint whether to manually compress or zoom in 1 is
* @ $ Multiple manually specify the compression/amplification ratio
* @ $ Is_water_str whether to add the watermark text 1 is
* @ $ Water_str watermark text
* @ $ Is_watermark whether to add watermark image 1 is
* @ $ Logo_path: watermark image path
* @ $ Is_display whether Image 1 is displayed
* @ $ Is_create whether the compressed image 1 is generated
*
* Note:
* 1. When a new image is generated, the image cannot be displayed, that is, $ isdisplay and $ iscreate cannot be set to 1 at the same time.
* 2. When the image width or height is less than 1000, you must manually set the compression ratio for compression.
* 3. We do not recommend that you enable the watermark. To enable the watermark, we recommend that the size of the original image be less than 1000.
* 4. The watermark text cannot contain Chinese characters
* 5. The newly generated images are in the original directory file and support n layers.
