tile drawing problem

[gbparis]

Hi

Actually I write a very basic isometric tile engine, it work fine except when the tiles are draw see the pic.

1/ the transparency problem.

2/ the tile.

3/ the alpha channel.

----------------------------------------------------------------------------------------------------

I got strange lines on the edges, I think its a problem with the " myTile.MakeTransparent(); "
Ive make some tests with alpha channel, search the web etc...

If you have an idea.

Thanks

Could you show the code that you use, and maybe a pictuire of the form when the images are drawn if you can.

thanks for the reply heres the pic:

 

[gbparis]

the code is not clean and extremly basic

public class test
{
private Bitmap tile = new Bitmap("tile1.tif");

public test()
{
tile.MakeTransparent();
}

public void draw(Graphics g)
{

for(int i=0;i<13;i++)
{
for(int x=0;x<4;x++)
{
g.DrawImage();
}

for(int y=0;y<5;y++)
{
g.DrawImage();
}

corr1 = nCorr1;
corr2 = Ncorr2;
}
}
}

Im sorry but could you now that I see it tell me to what you are referring as the unwanted effect?

I hope its not due to my poor english

the problem is the gray border of the tile, I Found the source of this problem,
that come when I resize the tile with photoshop, it interpolate and create some non pure black or white pixel.

I think I must cut the tile before drawing it...
