-* | File : GUI_BMPfile.c
|
|
|
-* | Author : Waveshare team
|
|
|
-* | Function : Hardware underlying interface
|
|
|
-* | Info :
|
|
|
-* Used to shield the underlying layers of each master
|
|
|
-* and enhance portability
|
|
|
-*----------------
|
|
|
-* | This version: V2.1
|
|
|
-* | Date : 2019-03-29
|
|
|
-* | 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.
|
|
|
-* 3.fix:line87 &bmprgbquad[i * 4] =》 &bmprgbquad[i]
