Playing card curl effect

[urosv]

Is there any way a can simply create Playing card curl effect. Back side to front side corner view only ? Any idea on solution will be greatfull. I need delphi sulution not inserting animated gif in delphi app.

Google "surface distortion graphics" and see if you find anything.

Or just use a couple of bitblts.

You'll need a bitmap for each:
1) the front side of the card
2) the back side of the card
3) a diagonal mask:

+------+
| a   /|  a = transparent
|   /  |
| /    |
|      |
|    b |  b = background color
+------+

Now blit the cards so that the bottom-right corner of (1) intersects with the top-left corner of (2) (or whatever) and then blit the background so that the diagonal takes out the lower-right part of the triangle:

+------+
|      |
|      |
|      |
|  +---+
|  | /
+--+

Depending on how you want to do it, you may want to rotate one 90.

If you just want a top to bottom flip, that makes it much easier. Instead of a 3rd bitmap, all you need is a DrawRect.

Hope this helps.

Thanks... this is my current idea and implementation, but the thing is that the corner bending must be dune quite nice like let say PageCurl efect like this

You can embed an animated gif into your project.
A third party component TGifImage (Freeware) will do this it comes with a basic gif animator.

It might even be built into new versions of Delphi (not sure about that)
