You can display additional map layers, such as StreetPro street maps, on top of a raster image. However, when you overlay raster and vector data in this manner, you may find it hard to tell which lines are part of the raster image and which lines are part of the vector data. Adjusting the display style of the raster image can make it easier to differentiate the separate layers. For example, if you set the image Contrast to a low setting, such as 30%, and set the image Brightness to a high setting, such as 70%, MapInfo Pro displays the image in a subdued style, which is appropriate if you want the raster layer to act as a backdrop.
If your raster image was scanned in and the resulting image is too dark or light, use the controls in the Adjust Image Styles dialog box to correct the display of the image.
