Follow these steps to establish the settings for a new logo or other legend image that you have inserted into the RockPlot3D scene, or for an existing logo that’s already displayed.
- For an existing logo, expand the Legends heading, if necessary, in the data pane to view the logo(s) currently stored with the RockPlot3D view. (You can have more than one logo.)
- Right-click on the logo to be modified and choose Options. (Or, just double-click on the logo to access its options.)
- Establish the logo / image options:
- Load Image: Click this button to browse for the image to be inserted into the RockPlot3D scene. You can choose from a variety of raster formats.
- Image Scaler: Use this setting to scale the image larger (> 1) or smaller (< 1). The horizontal:vertical aspect ratio should remain intact even if you change the scaling.
- Transparent Color: Check this box if you want to define a specific color in the image to be transparent. For example, if the logo is against a white background and you don't want to see that background, you can check this box and choose white as the transparent color.
! Note that some raster image formats use "lossy" compression techniques which may render "white" backgrounds not very white, so you may get varying results with this transparent color setting.
- Position: Use the displayed radio buttons to select the position for the image in the view pane. RockPlot3D maintains a boundary zone around the current image (sometimes overlapping it if the window is small or the image zoomed) in which the inserted logo will "float" independently of the image. The logo will not be resized as you change the size of the RockPlot 3D window or the zoom state of the 3D scene.
- Horizontal Offset: Use this item to make small adjustments to the horizontal positioning of the image. An entry of "0" (default) will place the image at the indicated Position (above). A setting of "0.1" will bump the image slightly to the right. A setting of "-0.1" will move the image slightly to the left. You should adjust the position in increments of 0.1 or the image may get bumped off the screen.
- Vertical Offset: Use this item to make small adjustments to the vertical positioning of the image. An entry of "0" (default) will place the image at the indicated Position (above). A setting of "0.1" will bump the image slightly upward. A setting of "-0.1" will move the image slightly downward. You should adjust the position in increments of 0.1 or the image may get bumped off the screen.
- Click the Apply button at any time to view the effect of your changes on the image. You may need to drag the Options window out of the way to view the display. You do not need to close the Logo Options window to apply and see the changes.
- Using the Apply button tells the program to invoke the changes you have made. You cannot discard changes once they have been applied.
- Click the Close button to close the Logo Options window.
