* | File : GUI_BMPfile.c

* Used to shield the underlying layers of each master

*----------------
* | This version: V2.0
* | Date : 2018-11-12
* | Info :
* 1.Change file name: GUI_BMP.c -> GUI_BMPfile.c
* 2.fix: GUI_ReadBmp()
* Now Xstart and Xstart can control the position of the picture normally,
* and support the display of images of any size. If it is larger than
* the actual display range, it will not be displayed.
