Show RGB888 content
- by Abhi
Hi all!
I have to show RGB888 content using the ShowRGBContent function.
The below function is a ShowRGBContent function for yv12-rgb565 & UYVY-RGB565
static void ShowRGBContent(UINT8 * pImageBuf, INT32 width, INT32 height)
{
LogEntry(L"%d : In %s Function \r\n",++abhineet,WFUNCTION);
UINT16 * temp;
BYTE rValue, gValue, bValue;
// this is to refresh the background desktop
ShowWindow(GetDesktopWindow(),SW_HIDE);
ShowWindow(GetDesktopWindow(),SW_SHOW);
for(int i=0; i<height; i++)
{
for (int j=0; j< width; j++)
{
temp = (UINT16 *) (pImageBuf+ i*width*PP_TEST_FRAME_BPP+j*PP_TEST_FRAME_BPP);
bValue = (BYTE) ((*temp & RGB_COMPONET0_MASK) >> RGB_COMPONET0_OFFSET) << (8 -RGB_COMPONET0_WIDTH);
gValue = (BYTE) ((*temp & RGB_COMPONET1_MASK) >> RGB_COMPONET1_OFFSET) << (8 -RGB_COMPONET1_WIDTH);
rValue = (BYTE) ((*temp & RGB_COMPONET2_MASK) >> RGB_COMPONET2_OFFSET) << (8 -RGB_COMPONET2_WIDTH);
SetPixel(g_hDisplay, SCREEN_OFFSET_X + j, SCREEN_OFFSET_Y+i, RGB(rValue, gValue, bValue));
}
}
Sleep(2000); //sleep here to review the result
LogEntry(L"%d :Out %s Function \r\n",++abhineet,__WFUNCTION__);
}
I have to modify this for RGB888
Here in the above function:
************************
RGB_COMPONET0_WIDTH = 5
RGB_COMPONET1_WIDTH = 6
RGB_COMPONET2_WIDTH = 5
************************
************************
RGB_COMPONET0_MASK = 0x001F //31 in decimal
RGB_COMPONET1_MASK = 0x07E0 //2016 in decimal
RGB_COMPONET2_MASK = 0xF800 //63488 in decimal
************************
************************
RGB_COMPONET0_OFFSET = 0
RGB_COMPONET1_OFFSET = 5
RGB_COMPONET2_OFFSET = 11
************************
Also PP_TEST_FRAME_BPP = 2 for yv12 -> RGB565 & UYVY -> RGB565
Now my task is for RGB888. Please guide me what shall i do in this.
Thanks in advance.
