DK - Symbols
	FAQ Feed

Q10488 -  The CGM symbol that I created using CorelDRAW seems to be left-bottom oriented in my DK application. How can I properly center it? The offset reflects a mistake in CorelDraw in how it creates CGM symbols. TatukGIS offers a CGM Center utility (SKU1052-458) utility to correct the offset of CGM symbols ... (Modified: 2004-07-15)

Q10299 -  I want to create CGM symbols using CorelDraw. How do I do this? Prepare your symbol as usual and export to CGM in format MIL-D-28003 (CALS) or MIL-D-28003A (CALS) When using CorelDraw to create CGM symbols for use in TatukGIS products, we suggest using only basic shapes because the TatukGIS CGM impl ... (Modified: 2004-06-24)

Q10543 -  Can CGM symbols be described as an ASCII text file and then imported into binary version? If so, what is the format of that ASCII text file? Yes. The documentation for the ASCII text file format can be found under different names: 1) NIMA: MIL-STD-2301A www.nima.mil 2) ISO: INCITS/ISO/IEC 8632-4-199 ... (Modified: 2004-07-15)

Q10231 -  I am trying to rotate a SymbolFont, but the source bombs for some reason. The problems are that the override rotate function for the SymbolFont never gets called and, I think, for some reason the draw routine hard codes the angle to 0. I am sending you the code to show what I am doing. Try using rot ... (Modified: 2003-11-21)

Q10235 -  I need to be very flexible in colors/fonts/lines (arrows) because I need to create a whole visual vocabulary, like dashed lines meaning "potential flights" one aircraft icon meaning a heavy aircraft and one meaning light, etc. So, what symbols does the DK support? Do you know of any existing library ... (Modified: 2008-02-18)

Q10236 -  How do I set the size of a SymbolCGM or SymbolBMP when using a repeating symbol to create a line? When lines are involved, set the size of the symbols composing the lines using - Width. ... (Modified: 2003-11-21)

Q10305 -  How can I put different icons/symbols at different points in a same layer? For example, one point with a bitmap of a bank and another with a bitmap of a church (both in the same layer) Prepare an ini file like this: TatukGIS Layer 1] Query=TYPE=1' TatukGIS Layer 2] Query=TYPE=2' Marker.Symbol=2.bmp ... (Modified: 2004-12-10)

Q10414 -  How do I display multiple, unique symbols on the same layer? The symbols might be used to represent GPS tracking points on the map and I want a different symbol to represent the position of each of a number of vehicles that are to be tracked. There are three ways to do this: 1) Use the layer propert ... (Modified: 2006-07-05)

Q10417 -  Which symbol types can I rotate using the DK? TrueType and CGM symbols can be rotated in the DK. To be rotated, the these symbols must be 100% vector, i.e. with no raster elements. Rotation of WMF symbols is not supported becase this would require a huge and costly effort. Bitmap (BMP) symbols also ... (Modified: 2006-11-22)

Q10565 -  I am using transparent bitmaps for my symbols. Normally this works great but when printing from some printers (especially Postscript) the symbols appear ugly and black and white. Not all printers support transparent bitmap printing. The workaround is use vector WMF, CGM, or Truetype symbols instead. ... (Modified: 2005-12-22)

Q10239 -  I am using LineSymbol : SymbolList.Prepare(logo.cgm' and as result I have a line with a short breaks between the individual symbols forming the line. How to solve this, i.e. eliminate the breaks? Check the following: 1) Make certain that LineSymbolGap=0. 2) Test your CGM symbol in our sample CGM vie ... (Modified: 2004-12-17)

Q10624 -  Is there a way to size symbols based on the zoom level? I would like to use complex line symbols with defined geometry related to specific scale ranges e.g. dash-dot-dot together with parallel solid line; geometry of individual segments expressed in mm and related to scale ... (Modified: 2007-10-22)

Q10777 -  Please provide sample code showing how to make labels/symbols scalable? 1. For a given layer lv, assign methods to the layer’s OnPaintShapelabel and OnPaintShape events: if ( lv is TGIS_LayerVector ) then begin lv.OnPaintshapelabel : G_ZoomLabel ; lv.OnPaintShape : G_PaintShape ; end; 2. In the impl ... (Modified: 2007-10-23)

Q10611 -  I am using Params. Area. Symbol to fill the area using a bitmap symbol. Sometimes even when I set Params. Area. Symbol. Gap = 0, a horizontal or vertical gap occurs between the symbols. The problem is caused by the scaling of the symbol. Please use Params. Area. Bitmap instead. This will guarantee a smooth ... (Modified: 2005-03-09)

Q10628 -  Does TatukGIS provide the toolbar icons that are used in the TatukGIS Editor and free Viewer, so that I can use the same icons in my DK application? Yes. We provide all the TatukGIS toolbar icons with the DK retail version. ... (Modified: 2005-04-20)

Q10680 -  Is possible to set two colors for a CGM-symbol in the the DK? If yes, how? Yes, it is possible to set two colors for Marker colors. Set Marker.Color and Marker.OutlineColor. For area fills, the color will always be Area.Color and for areas, the outline color will be always Area.OutlineColor. However ... (Modified: 2006-02-08)

Q10726 -  Why am I unable to perform SymbolRotate with CGM symbols containing raster elements? What software do you recommend to create CGM symbols? TatukGIS products support only CGM vector features, so the CGM symbols should contain no raster elements. Any Bitmap features, therefore, should be vectorized ... (Modified: 2006-10-28)

Q10733 -  Is there a way to pre-prepare a symbol list so I can rapidly set/change the symbols associated with points on my tracking layer? Yes. Just use the following: Shape.Params.Marker.Symbol : SymbolList.Prepare( xxxxx ) ; SymbolList should be a global instance of XGIS_SysmbolList The first time symbol ... (Modified: 2006-11-28)
