Adjusting the Translucency of a Raster Image - MapInfo_Pro - 2023

You can adjust the percentage that layers show through raster images. A translucent image allows you to partially see through the image. Translucent images can be layered on top of other layers so that the lower layers are partially visible through the image.

To adjust translucency of a Raster Image:

1. Open a raster image table.
2. On the TABLE tab, in the Maintenance group, click Raster, and Adjust Image Styles.
3. If the Choose Raster Table dialog box opens, select the raster file to adjust and click OK.
4. In the Adjust Image Styles dialog box. Use the Translucency slider control to adjust the percentage that layers show through the raster image.

   Translucency can be set between 0-100%. An image with 0% translucency is completely opaque (or cannot be seen through). An image with 100% translucency is completely transparent (or completely invisible).

5. Click OK.

This setting becomes your default setting for the raster table (TAB file). You can override the default setting by adjusting translucency per layer on a map.

Adjusting the Translucency of a Raster Layer on the Map

You can adjust the translucency on a per layer basis for your map. This overrides, but does not change, the default translucency setting for a layer (set for the TAB file). This is useful when you want to see the layers of your map under a raster overlay, but you do not want to change the translucency set for the raster file.

To adjust the translucency of a raster layer on your map:

1. On the HOME tab, in the Windows group, click Tool Windows, and click Layers from the list, to open the Layers window.

   If you have the Explorer window open, you can use the layers list in it.

2. Double-click on the layer name in the Layer list to open the Layer Properties dialog box.
3. On the Layer Display tab, use the Translucency scale bar to adjust the translucency level of the raster image.

   For more adjustments, including translucency, check the Style Override check box and then click the Style button. This opens the Adjust Image Styles dialog box where you can make contrast, brightness, greyscale, and translucency adjustments, and you can make the layer transparent.

4. Click OK to save your changes and close the dialog.
