Bitblt stretchdibits
WebBit blit (also written BITBLT, BIT BLT, BitBLT, Bit BLT, Bit Blt etc., which stands for bit block transfer) is a data operation commonly used in computer graphics in which several bitmaps are combined into one using a boolean function.. The operation involves at least two bitmaps: a "source" (or "foreground") and a "destination" (or "background"), and … WebSep 2, 2014 · The SetDIBits function sets the pixels in a compatible bitmap (DDB) using the color data found in the specified DIB. In my case, the DIB is the 32bpp RGBA array, and the DDB is dispBMP which I create with CreateCompatibleBitmap. So instead of my call to SetBitmapBits, this is what I did: BITMAPINFO info; ZeroMemory (&info, sizeof …

Unfortunately, MCF and Win32 don't give me the same facilities to make the operation via a memory DC. I have tried to do a similar process with Win32 StretchDIBits, but it resulted in a black screen, so something went wrong. http://computer-programming-forum.com/82-mfc/71ddfdc3cd8c13a5.htm
WebJun 15, 2024 · But I would say BitBlt should be faster than StretchDIBits because former does not resize image, so it needs to do less/simpler operations when its blitting pixels. … In this article. The BitBlt function performs a bit-block transfer of the color data corresponding to a rectangle of pixels from the specified source device context into a destination device context..
