This is another attempt to push the Windows window limits.

By the way the next step would be to play AVI or Flash animation in the background.
I shall have a look at José's COM example to play a flv file.
If you know of a nice, smooth, FLV animation, something like clouds moving slowly or lights effects, please let me know.

Patrice,

this is one of the best effect I've seen since a lot of time.

Great!

Hi Patrice,

very hypnotic demo as usual.
I just changed %TIMER_DELAY to 20, making it run at 50FPS, and it still uses just 10% CPU power!

But there is one mystery I cannot solve - where in code do you perform the image shifting? Smiley


Thanks,
Petr

See the WinScape's dedicated zaniskin.inc file.

New API(s):
Code:
FUNCTION zAnimResetXX(BYVAL N AS LONG, BYVAL RW AS LONG) AS LONG
    STATIC WasN AS LONG
    IF RW THEN WasN = N
    FUNCTION = WasN
END FUNCTION

FUNCTION zAnimUseStretchMode(BYVAL N AS LONG, BYVAL RW AS LONG) AS LONG
    STATIC WasN AS LONG
    IF RW THEN WasN = N
    FUNCTION = WasN
END FUNCTION

Modified API: zMoveBackground
Code:

             CALL zComputeAspect(800, 600, rc.nRight, rc.nBottom, xP, yP, xS, yS)
             STATIC FlipMove AS LONG
             IF zAnimUseStretchMode(0, 0) THEN
                CALL GdipDrawImageRectRectI(graphics, Img, xP, yP, xS, yS, xx, 0, 800 * ((ImgW - xx) / 800), 600, %UnitPixel, ImgAttr)
             ELSE
                CALL GdipDrawImageRectRectI(graphics, Img, xP, yP, xS, yS, xx, 0, 800, 600, %UnitPixel, ImgAttr)
             END IF
             IF zAnimResetXX(0, 0) THEN xx = 0: CALL zAnimResetXX(0, 1)
             IF FlipMove = 0 THEN
                xx += 1: IF xx > imgW - 800 THEN FlipMove = -1
             ELSE
                xx -= 1: IF xx < 0 THEN FlipMove = 0: xx = 0
             END IF

How much when running in stretched mode, and also how much in full screen mode with or without stretching?
and tell me if you use XP or your new VISTA 32x?

Hi Patrice,

I had chance to test it only on XP box so far, as it is mine. The Vista one is not in common perimeter of my influence Smiley
Interesting observation - in 800x600 those 2 effects differ, in fullscreen they are both quite demanding - probably reaching some system component bottleneck?

When I render OpenGL quad with scrolling images you use, I get easily 0% even at 1280x1024, so I guess CPU/Memory is not fast enough on my PC.

Ok, Petr, thank you for the detailed feedback.

On my HP HDX18 running VISTA X64 and using the Sky background in full HD mode (1920 x 1080),
it ranges between 18-24, whatever the stretch mode being turned on or off.

This means, better to use the full screen mode with a horse race powered computer Wink

As a matter of comparison, on the same computer, MovieBox, playing a full HD MKV movie, ranges between 27-36.
