In this tutorial I will show you how to create a rolled edge. Similar to the one around the logo above.
For this effect you will want to set up a few things first to make the task easier. After opening a new image set up a grid. The Grid & Rulers setup can be found under the Tools menu item. You need to set the grid to a size that will make it easy to get the size you want for the edge. The thickness of the border will be a multiple of the distance between the grid lines. I set mine up for a 0.1 inch spacing in both directions. Check Snap to Grid, and Show Grid. I want to be able to draw a rectangle mask with rounded corners. Since mask tool doesn't have a rounded corner option, I will make an object in the shape I want, then create a mask from the object. To set this up select the Rectangle tool. Open the tool settings or use the property bar and set the roundness to 100%. Make sure Render to Object is selected.
Draw the shape. Create a mask around the object. Save the mask as a channel, naming it 'Inside'.
What you need to do now is create a mask that is larger, but has the same shape as the first one. Unfortunately, when the mask is changed more than a few pixels it becomes distorted. If you are working with a small enough ring, expanding the original 'Inside' mask will work. However if you expand or reduce it too much you will start getting round parts that are flattened.
You can also change the size of the object and create a new mask from the object. Even then, with large changes and round objects, you will get some flattening on the curves. So...
Leave the mask in place as a reference. Then draw a new object starting one grid location up and left from where the first object was started. Drag the shape out so it is one grid line larger than the mask all the way around. Create a mask from the new shape. Save it as a channel naming it 'Outside'.
If you have a hard time hitting the right starting point, drag a couple of guide lines over and place them against the sides of the first object. The intersection of the guidelines is the original start point.
Click on the Mask tool. In the property bar set the mask mode to XOR.
Load the mask named Inside that you saved earlier. Since the mask mode is in XOR, this will create a mask in the shape of a ring. Save the mask to a channel, naming it 'Ring'.
When you combine the masks with the XOR mode selected, any part of the masks that don't overlap will be inside the mask. Any part that does overlap, will be outside the mask. To see a visual demonstration, try this. Open a new image. Set the mask mode to XOR. Draw a circle mask. Then draw another one that overlaps the first one. Using Edit Fill, fill the mask with a solid color.
After this step make sure you set the mask mode back to normal. This is also a good time to turn off the Snap to Grid, Guidelines, and the Show Grid.
With the mask mode in normal, load in the mask named Inside, that you saved earlier. Using Edit Fill, fill the mask with 50% black. Remove the mask. Then apply a Gaussian blur of 3.0. The amount of blur you use will depend on the size of the object and the resolution of the image.
Select Emboss from the menu Effects | 3D Effects. Use settings to get something like what is pictured here. The settings you use will vary depending on how much of a blur you used and how much of a highlight and shadow you want. I used the following settings: Color of Gray, Depth of 5, and a Level of 100. Set the light in the upper left. I used a light direction of 125.
Reload the mask named Inside. Create a new object from the mask.
Select the background to make it active. Clear the background using Edit Clear. This will leave you with a nice button, all it needs is a little color. For now make the new button invisible by clicking on the eye icon in the docker window.
Now do the same thing with the Ring mask. Make sure you are in the background layer. Load the mask named Ring. Fill the mask with a 50% black. Remove the mask. Then apply a Gaussian blur of 3. Emboss the blurred image using the same settings. Reload the mask named Ring, and create an object from the mask. Make the background active, then clear it. Leaving the ring shaped object.
Click on the eye icon to make both of the objects visible. Create a new layer. At the bottom of the docker window select a merge mode of 'Overlay'. Save this file as a CPT image. It will be the base for many buttons.
When you are done you should have four layers, the background, a layer with the inside shape, one with the ring shape, and an empty layer, where you will be applying the color.
Now for the fun part! Load the mask named Inside. Make sure you are on the color, or top, layer. Fill the mask with a colorful fill pattern.
Make sure you are on the Color layer, then load the mask named Ring. Choose another fill pattern, or a solid color. Fill the masked area.
You can keep loading the different masks and changing the fills until you get a button you like.
