Hello.
I wish to ask about the help. Me interests fast output of images on ppc as in library sprites.dll, but without additional opportunities. Only drawing bitmaps (BitmapEx object for example) on coordinates. And necessarily readable property ' image '. And refresh on a command ' tick ' as in sprites.dll
There can be someone from experts can make it?:BangHead::sign0104:

There is almost no overhead in drawing a Bitmap object on the screen with a Drawer. I guess that this is also correct for BitmapEx as well.

UP!
can anyone help? i want only a simple Sprite.dll without any functions.
it must only draw bitmaps on coordinates when (forexample) we call drawimage() but not show changes while we not call 'tick' (or refrash)

Why not draw on a Bitmap then when you want to see the changes assign it to the Image property of a Form or Image control?

What do you mean by "drawing in sprite.dll"?

in sample for sprite.dll sprites move very smoothly (witk tick every 50ms) but when i'm try to "move" and "animate" sprite,using ImageLibEx and Image i have a slideshow.
it is a simple code:
image1.image=bitmapex.value
drawerex.new2(bitmapex.value)
.... (some drawing)
image1.refresh

i have no blinking,all nice but my 'sprite' (drawed image) move jerky

I've looked at the underlying .NET code and you won't get faster than what you are doing. You are drawing directly on the bitmap that the Paint event draws to the screen. Possibly it is the actual drawing you are doing that is slowing it down.

image1.image=bitmapex.value
drawerex.new2(bitmapex.value)

The above two lines only need to be done once so they need not be in your drawing routine. You will only get the full speed when optimised compiled.
