[Solved] Calculate pixel coordinates within vector drawing

[Michael Vogel]

I am using TranslateCoordinates and ScaleCoordinates to draw a map as large as possible within a windows frame. But I need to save the used pixel coordinates for doing a simple mouse hover function. Of course I can do the inverse calculations but is there a more simple way to get the pixel coordinates from the vector coordinate system?

Hi Michael, ... I'm not sure if this is what you want, but maybe you can use custom drawing.

A.f.a.i.k, you will get an interrupt call for each drawn pixel.
Maybe you can store the Pixel coordination to a Buffer (Matrix, Dim Array,...) to compare to your mouse coordination later.

(I've never worked with custom drawing, so I'm not sure if this will be a working solution.)
