* | 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: V2.0
|
||
|
|
* | Date : 2018-11-12
|
||
|
|
* | Info :
|
||
|
|
* 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.
