Bump+Maps



__Any area of any layer can be bumped up using any layer as map.__ There are no such limitations for using this effect, but it does not make sense if you start using a transparent layer to aply bump map on another layer, or if you try bumping a transparent area of a layer. __The stacking order of layers is not important__.
 * Limitations**

To get 100% results from this plugin, use BLACK & WHITE layers as map to use for bumping an area of other layer.
 * Recomendation**

Here we will create the same effect shown above, using the powerful plugin __Bump Map__.
 * Core Practice and Tutorial**

Follow the Steps:

> > The layer **Acutal** will be containg the actual image, we have to bump some area of, (//here I used only a gradient//). > The layer **Map_only** will be used to create the map (//The area which has to be bumped over the layer named **Acutal**//). > > > > > > > Finally we have a layer **Map_only** which cotnains a BLACK & WHITE map which will be bumped up on layer named **Atual**. Order of layers in Layers tab is as below (//Although it is not important//): > > > > > > Now it is time to apply the Effect **Bump Map** I have been talking about. > > > > On top-right corner of this window there is a list of layers you have, this list is captioned __B__ump map, you simply select the layer named **Map_only** and click button **OK**, which will immediately update the layer **Actual** with a bumped circle in it. > > > **More Adjustments using scroll options on the plugin window** > Azimuth : it is simply used to adjust the light position. > Elevation : acts as contrast. > Depth : Gives more 3d depth to gumped portion if value is increased. > X/Y Offset : move the map behind actual layer. > Ambient : give/remove depth of unlightened part of bumped area. > **TIP** > If the layers used as map are deleted, they leave no effect over image, becuase bumped layer has alread ||
 * * Start with an empty image (**File** > **New**), of 300x300 or any preffered dimensions.
 * Insert New Layer and name it **Map_only**.
 * Insert New Layer and name it **Actual**.
 * Select the Layer **Map_noly** in layers tab, and fill it using solid white color, and select a circle region on it, using elliptic region selection tool (//The second icon on gimp main window//), and fill this selection with solid black color, so that your layer looks something as below, in image window:
 * Remove any selection, using menus in image window **Select** > **None**.
 * Now select the layer named **Actual** and fill it using any gradient, I have used golden with style Linear, so the image window will look as following screenshot, if layer **Actual** was over all other layers:
 * Select layer named **Acutal** and go through menus within image window **Filters** > **Map** and click **Bump Map...**. A new window will appear asking you too many things, do not get confused here it is so simple. The window looks like the one below:
