You can render based on fields containing non-numeric information as well. For instance: RENDER=( Sex = 'MALE' ) or RENDER = ( Street Type = 'Main' ) RENDER = ( Street Type = 'Secondary' ) Be sure to use ' ' marks and not " " to connote a non-numeri...

You should use SQL syntax in any Query. The "Feature" field seems to be a text field in this case. This means that the search term must be enclosed in ' marks. Therefore try: Query=Feature='Principal Highway'

If the styles (colors, polygon area fills, line types, label appearance and fonts, symbols, etc.) used to render each vector area, line, point, etc. are static, the IS LITE performs the same as the full IS version. But, it the thematic presentation is to change dynamically,...

The solution is to draw the street map line layer twice, i.e., have the same layer two times in the project, one layer on top of the other layer. First draw the full width lines representing each road or street in the lower layer. Then render the same lines a different co...

Sure: sqlDC := CreateOleObject('ADODB.Connection'); sqlRS := CreateOleObject('ADODB.Recordset'); sqlDC.Open('FILEDSN=GMINY.DSN'); sqlRS.Open('select id, agri FROM QTocounty ORDER BY id', sqlDC); // order by ID is important!!!! // ll is your layer with a unique...

You can perform value dependent rendering using a *.TTKGP file (TatukGIS project file) or *.INI files. For example: [TatukGIS Layer1] Path=mylayer.shp [TatukGIS Layer1 1] Render=severity MarkerColor=GREEN [TatukGIS Layer1 2] Render=severity>=5 M...

Yes. Use what we call an 'In-memory' layer (TGIS_LayerVector) to perform the animation. Lines, points, and polygon shapes may be created on this layer using your own logic or you can import data from existing sources using the built-in DK ImportLayer method. Every shape in a...
