Combining two bitmaps together?

[TheHardew]

Hello!

I've got two images that I'd like to combine during runtime:

Active.bmp and HighPerformance.bmp are bitmaps I'd like to combine and example.bmp is an example of how I'd like it to look. Do you know how to combine them during runtime? I use just win32.

Use TransparentBlt() to draw active.bmp on top of the other. Or use the Rectangle() function instead of active.bmp.

Thanks ahcfan, TransparentBlt() worked:

 // load 2 bitmaps - mask and background, create variables for default bmps from dcs
HBITMAP mask = LoadBitmap(GetModuleHandle(nullptr), MAKEINTRESOURCE(IDB_ACTIVE)), 
result = LoadBitmap(GetModuleHandle(nullptr), MAKEINTRESOURCE(IDB_HIGH)), old1, old2;

// create dcs
HDC maskDc = CreateCompatibleDC(nullptr), res = CreateCompatibleDC(nullptr);

// remember old bmps from dcs
old1 = (HBITMAP) SelectObject(maskDc, mask);
old2 = (HBITMAP) SelectObject(res, result);

// combine bmps
TransparentBlt(res, 0, 0, 64, 64, maskDc, 0, 0, 64, 64, RGB(255, 255, 255));

// return default bmps, get our bmp back
SelectObject(maskDc, old1);
result = (HBITMAP) SelectObject(res, old2);

// clean up dcs
DeleteDC(maskDc);
DeleteDC(res);
