/*****************************************************************************
* | File : GUI_BMPfile.h
* | Author : Waveshare team
* | Function : Hardware underlying interface
* | Info :
* Used to shield the underlying layers of each master
* and enhance portability
*----------------
* | This version: V2.3
* | Date : 2022-07-27
* | Info :
* -----------------------------------------------------------------------------
* V2.3(2022-07-27):
* 1.Add GUI_ReadBmp_RGB_4Color()
* V2.2(2020-07-08):
* 1.Add GUI_ReadBmp_RGB_7Color()
* V2.1(2019-10-10):
* 1.Add GUI_ReadBmp_4Gray()
* V2.0(2018-11-12):
* 1.Change file name: GUI_BMP.h -> GUI_BMPfile.h
* 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.
