Hello.

I want to load and analyse a bitmap.
To read the colour of a coordinate and translate it to water or un-passable terrain.

But I dont get the dbPoint to work.
It returns zero all the time.

Can someone submit example code?

Use memblocks.
dbMakeMemblockFromImage(mb,img);
from that you can look at the color of the image.
int pos=12+(y*width+x)*4;
DWORD Color=dbMemblockDword(mb,pos);

The fastest code is the code never written.
