Moving images

[Julius Fuchs]

Hi,

what's the best way to move an image let's say from the top left to the
bottom right in e.g. half a second without flickering? I considered a timer
which modifies the position of an image but wonder if there are better ways.
Perhaps using a paintbox and draw methods instead or so.
Does anybody have other suggestions?

Thank you

If your using GDI you'll neve get anything really smooth due to the way
windows invalidates. That was my experience anyway if anyone does know a way
to use GDI for a smooth animation i'd be interested to know myself. If
you're moving just a circle or some basic shape like that, that can be done
there are tutorials on the net. Personally i use Direct X

You can use a double buffered panel.
You can find many infos on internet if you search for it.

Or you can try the canvas control that you can find in my little graphic
library at www.neodatatype.net

That also will not be totally smooth though, i also tried that myself. it
does help tho.

In drawing I can reach a good smoothing level (not optimum for really fast
animations, of course).
If there is some tricks in the algorithm that move objects I can't say :)

Until now I didn't have the time to have a look at this thoroughly but it
looks promising.
To be a little more specific: I want to make a chess program with the pieces
"fly" over the board when they are moved. Other programs do that as well and
without flickering.
I just wonder if I should draw every piece manually or use images and change
their position. As I said, I didn't have the time to try both methods and
compare the results. What do you think might be best?

Thanks

Well i am biased, i always go for directx for any graphics as it gives th
ebest performance. However if you are not used to it, this will take you a
while to learn...tho managed direct x has made directx much easier now. For
me there are so many issues with gdi for good smooth aniamtions and you have
to do so much tweaking its just not worth it unless your graphics are very
simple.
