Hello,
to display bitmaps from SD card I use the drawing function
Code
GUI_BMP_DrawEx(APP_GetData, (void*)&SD_File, 0, 0);with the import function
Code
int APP_GetData(void * p, const U8 ** ppData, unsigned NumBytesReq, U32 Offs)
{
UINT NumBytesRead;
U8 _acBuffer[2 * XSIZE_PHYS]; /*buffer must hold at least one line (2 byte * 800 pix)*/
f_lseek((FIL *)p, Offs); /*set file pointer to the offset location*/
f_read((FIL *)p, (void *)_acBuffer, NumBytesReq, &NumBytesRead); /*read data into buffer*/
*ppData = (const U8 *)_acBuffer; /*data pointer = beginning of the buffer*/
return (NumBytesRead); /*return number of read bytes*/
}My color order is RGB.
Code
#define GUI_USE_ARGB 1 /*order of colors R|G|B*/On the screen the bitmaps are shown with red and blue swapped.
On a PC the colors the same bmp files are displayed correctly.
It looks like the saved bitmaps are coded RGB but GUI_BMP_DrawEx() expects BGR. How can this problem be solved?
Regards
Jan
