This means turning off the default feature which ensures that labels (even from different layers) never overlap. You turn this feature off by setting:
Params.Labels.Allicator=False.

The rule is one point - one label. But consider these possible solutions:
- Use a multi-field label, which provides for the presentation of two or more types of information in a single label.
- If you really require two labels for a given point, prepare a second layer with a point in the same position, but with a different label position.

By default, the appearance of labels are given view priority over (appear on top of) geometric features, regardless of the z-order number of the layer that contain the labels. This is presentation that most customer want in most situations.
You can, however, turn off this behavior off, either using the project level setting or code (LabelsO...

This can be done by overriding the TGIS_ControlLegend.OrderChange event. For example, in Delphi:
procedure TForm1.LegendOrderChange(Sender: TObject);
begin
; if MyLayer.ZOrder 0 then begin
; ; ; MyLayer.Zorder := 0 ;
; ; ; Legend.Update ;
; end ;
end;

Yes. Use the Property Offset to control the distance of the geocoded address point from the street line. The Property Offset also controls the distance of the first and last address on a street segment from the beginning/end of the street. The Offset distance is defined in Map Units.

This reflects an MDA related deficiency in Visual Studio 2005 which causes any API intensive application to run slow in the VS2005 development environment. The speed of the DK.NET/VS2005 compiled application is normal when it is run outside of VS2005. For more on this issue, refer to the information at the following links:

Although we never intentionally added such a feature, this can be performed using the COGO editing feature that is supported in the Editor. First select a shape using the Edit object tool and then open the COGO tab within the Selected panel. Within the COGO tab, edit the x,y coordinate values of vertex number 0 to reflect the desired location. Beca...

Beginning with the DK-ActiveX version 8.0.0.500, there is only one version of the product for both development and deployment. The procedure is to copy the ttkGISDK.ocx to the deployment computer and register it using a setup routine or “regsvr32 ttkgisdk.ocx”. Just to be clear, the deployment of a DK-ActiveX application is free of any TatukGIS activa...

The DK can be used to import data from a *.txt, Excel (*.xls) spreadsheet, or database file as point features in any of the write-supported vector layer formats, eg., SHP, MID, DXF, GML, KML, etc.
The following provides a skeleton of the method:
lv := TGIS_LayerVector,Create ;
lv.Name := 'my_layer' ;
GIS.Add( lv ) ;
lv.AddFie...

Yes. The DK supports vector editing features and some topological operations as a development tool, to allow developers to build shapefile drawing and editing functionality into their custom GIS applications. Refer to the DK Editor sample, which is also provided as a compiled application.

The DK default OpenGIS (OGC) SQL DB layer storage type is OpenGISBlob, which reflects WKB. The DK developer can change the storage type to OpenGISNormalized, which is similar to WKT but with the x and y coordinate values organized as separate database columns.

The easiest way to learn about the visual layer property control is to review the tutorials provided for the free TatukGIS Viewer product. The TatukGIS Viewer, Editor, Internet Server (full and LITE versions), and DK products all contain the same Visual Layer Properties Control. The features of this control are well covered in the Viewer tutorials, wh...

No. TatukGIS directly supports industry standard data formats and the formats of other leading companies in the GIS industry, e.g., ESRI, MapInfo, Intergraph, Bentley, Lizard Tech, ERMapper, the leading satellite imagery vendors, etc. We also support the openly documented OpenGIS Simple Features for SQL format. All formats are supported “natively”, whi...

TGIS_Units is a unit conversion component relating to projections. It will allow you, for example, to determine whether your output is in meters or miles. You can use this class to convert between unit types. Conversion from meters to nautical miles, for example, is achieved as follows:
units := TGIS_Units.Create(gisUnitsTypeMileNautical);
mile...

Yes. The export procedure provides settings to filter the data that is exported based on extent, selection, shape type (polygon, line, points, or multi-points), attribute query, or any combination of these parameters. For example, you could export only the line shapes from a DXF file with specific attribute values or ranges. The possibilities are po...

There are two methods to convert vector map data between file types (formats).
1. Import operation. The creation of a new (empty) vector map layer requires the user to specify the file type of the layer. If a vector map file of a different type is then opened into that layer, this results in the conversion of that data into the file type of the...

Use of the Scale property requires that you assign map units (such as meters, feet, nautical miles, radians, etc.) to the subject map layer.
Attach:
GIS_ViewerWND1.Units.Units := gisUnitsTypeMeter ;
and then, for example:
GIS.Scale := 1 ( means 1 meter on the screen is one meter on the map)
GIS.Scale := 1/1000000 (means map...

TatukGIS products, e.g., the Developer Kernel (DK), Internet Server (IS), Editor, and free Viewer, contain a powerful visual layer property control to enable the user to set any visual style, e.g. colors, line widths, line types, polygon fills, polygon boarders, labels, icons/symbols, bitmap images, transparencies, etc., to selected vector objects in ...

We test TatukGIS products older Windows operations systems (including Windows 2000), but only with all service packs (updates) issued by Microsoft applied. So first and foremost, verify that all Microsoft service packs for your version of the Windows operating system have been applied on your computer.
