;==============================================================================; ==> Part 150 : Mandelbrot fractal, FPU, Screen buffer !;------------------------------------------------------------------------------; Hello, why not analyze some complex values ...; Clicking "Calculate" in the menu bar starts calculating.; Choosing "Settings" will open a Popup menu, you can select your preferences.; Press "Esc" to abort calculating.; I wish you a nice journey through the world of Mr. Mandelbrot. ; In the windowproc WP1, reacting to a WM_CREATE message I get a; MAIN device context for the client area of the window, creating a; compatible BITMAP for that (!), creating a compatible (!) device context and; now selecting an object (the BITMAP) into the compatible device context.; Now I call API "FillRect" to clear (!?) the created back buffer and at last; I call API "ReleaseDC" to release the MAIN device context for future use.; Note: the compatible device context is still present (needed on WM_PAINT) !; We delete this only on WM_DESTROY.; On WM_PAINT I perform a simple Bit transfer (API "BitBlt" ) from the created; back buffer to update the screen.; Another interested part of this win32asm example is located on WM_COMMAND.; Here I calculate the fractal using the FPU, the calculated pixel/color will; be written to the back buffer and also to the screen, which will increase; the time to calculate up to 25% (right, that's the drawback here...).; Thanks to Wayne J. Radburn for the WNDCLASSEX.style CS_OWNDC tip.; ; Test Department [email protected]
