@Benni003 remind me the current issues you face, please?
Kartoffel told us both that AA and shaders will have no effect.
This is to be a 2d game correct? So then you should need lots of 2d assets. When you scale down the current quad you have 2 issues
1) an untextered black boarder
2) a jagged ugly texture quality.
My solution would be how they would do it in a real game.
1) never scale the quad, clear it, then repaint it with a different texture
2) if you have to zoom in %50, open you digital paint program and modify the %100 texture there. You can use the scaling filters of a 2d art program to create a second texture, or you can actual paint the second texture.
3) You will not be able to quad a giant area one, then move around it and zoom in and out. Not like loading a 3d world. Your world should be constructed of many textures that relate to a grid set-up. You will need to paint and repaint the textured quad(s) to move around on the world and zoom in and out.
You may question this advice, however there is a reason that Zelda and other games work how they do.
Thanks for the fun

Exactly ! I would do it like a the logic of a lod system.
create 4 step graphics for %25, %50, % 75 and %100, then you could still do a bit of scaling also. But no more the %25(+- .25) before changing steps. So if you are at %0 zoom you can scale down the quad to atmost scale = .75. Then change to the next step graphic and scale it up top scale =1.25; . That step can be scale all the way down to scale = .75 before changing the next step image.
This gives you a smoother none stepping zoom and reduces the blur and jaggs

As for Anno online, it is a 3d game and also if we could compete with UbiSoft we would be talk on this forum Now.

Hi,
you could 'draw_quad' the full map on a not visible bitmap at its pixel to pixel scale and use it as source map in a shader over a view or a 'bmap_process' inside a loop. It would let you use any scale on the visible bitmap with the proper samples. I am afraid anisotropic filter does not work on texture samples but linear interpolation is enough, I guess. It is pretty easy to develop. I can help.
Salud!

@txesmi that sounds good, but I haven't the knowlege to do it  I don't have a view, because I haven't any 3d Level, so I think to use bmap_process is better... Would be great, if you could give me an example for this.

Here you go!  main.c

#define skScaleNext skill8 // needed a map scale smooth transition variable
void main ()

wait(1);
BMAP *bmpMap = bmap_create ( "grid.tga" );

bmap_process ( bmpScreen, bmpMap, mtlCamMap );
wait(1);
}
mtl_remove ( mtlCamMap );

I have only one Problem. Zooming is good working, but to Have a good Quality I want to draw higher res. Pictures and then integrate a zoom-out function. But the Draw_quad function is not working outside the original Resolution size. If I soom out, the Pictures out of the original res. size are not drawn, even when the res. of bmpMap is higher... 
bmap_rendertarget(bmpMap,0,1);
draw_quad(bmap_test,vecto(1,500,0),NULL,NULL,NULL,NULL,100,NULL);
draw_quad(bmap_test,vector(1000,500,0),NULL,NULL,NULL,NULL,100,NULL);
draw_quad(bmap_test,vector(2000,500,0),NULL,NULL,NULL,NULL,100,NULL);
bmap_rendertarget(NULL,0,0);
