KB10546 - Problem with the GIS.Zoom (pixels verus twips).

Question from a DK customer:

In my project file I have:

[TatukGIS Layer1]

Path=layer.shp

Name=cities

Visible = false



[TatukGIS Layer1 1]

MinZoom=340

Visible=true

The Layer becomes visible even if GIS.Zoom reports only 27. What's wrong?

Specify instead:

MinZoom=-3000

Negative values correspond to PIXEL related calculations (such as GIS.Zoom). Positive values correspond to TWIPS related calculations (such as GIS.ZoomEx).
