Floating Image Options

The Float Image layer is offered in most RockWorks programs that generate 3D scenes. It is used to display a raster image (BMP, JPG, EMF and WMF, PCX, PNG, TGA, TIFF) floating in 3D space at a specified elevation. Click on the Float Image tab to access these settings.

! The raster image file must reside in the current project folder.

Menu Options

• Float Image
  Check this item to include a floating image in your 3D scene.
  Click on this tab to access the float-image settings.
  
  
  • Image Source
    
    • Project Image: Choose this option if you wish to float the current Project Image.
    • 
      
    • Other Image: Click this option to float a different image. You will need to define which image and its locations.
      • File Name: Click here to browse for the name of the bitmap image you want to float. Supported formats are listed above.
      • Image Location Defined By: You have several options for entering the coordinates at which the bitmap is to be displayed in RockPlot3D.
        • Project Dimensions: Choose this option if the current output dimensions represent the border coordinates for the image you've selected.
        • World File: Choose this option if there is an accompanying World File which defines the image extents.
          • Automatic: Choose this option if the program is to search automatically for a World File with the same file name as the Image File, above, and with either world file name extensions: *.bmpw or *.bpw (italicized letters are replaced by the extension characters of the Image File, as in *.pngw or *.pgw, etc.)
          • Manual: Choose this option to manually browse for the World file to be used for georeferencing the selected image.
        • Manually Specified: Choose this option to type in the coordinates for the edges of the image.
          • X-Minimum: X or Easting coordinate represented by the left edge of the image.
          • X-Maximum: X or Easting coordinate represented by the right edge of the image.
          • Y-Minimum: Y or Northing coordinate represented by the bottom edge of the image.
          • Y-Maximum: Y or Northing coordinate represented by the top edge of the image.
          •

  • Float Options
    • Elevation: Enter here the elevation at which the bitmap is to be floated.
    • Set Transparent Color: Check this box to specify a specific color in the bitmap image to be displayed transparent. For example if the image has a white background and you would like that part to be see-through, you would select white.
      If activated, click on the color box to choose the image color that is to be set to transparent.
    • Layer Name: Type in a name for this layer; it will simply be used to label the floating bitmap in RockPlot3D. For example, if the image represents a satellite image, you might name this layer "Satellite Image."
