ADDING IMAGES FOR COMPOSITING


1. We have already discussed how to add content like trees, people, and cars with Sketchbook DesNow we’ll create an example in which we import a tree for a floor plan, remove its create a shadow.

2. We have already worked in the building’s lobby. Now let’s add a Texture Fill for the lawn around it. We simply import a map with gra

3. After scaling down, we can see how the scale of the grass is credible. Many of these maps are meant to cover a couple of feet of grass, so they look huge when placed in a floor plan. Sketchbook Designer will by default try to map the texture to the extents of the area to fill, so in cases like grass, it will definitely be out of scale.

Once we select the white (we may also need to tweak the tolerance to get more or less pixels with a similar color to the point where we pick) and delete the background, you will have a transparent tree ready to use.

5. Move the tree to the right location by using Sketchbook Designer’s Transform tools. We may also need to make some other transforms. In this case, we can do a uniform scale using the grip shown below. The adjacent grips on the middle of both sides of the control are faxes.

7. Probably one of the most powerful among the Transform tools is Warp. There are three controls in the toolbar (Scale, Distort, and Warp). Scale will make the corner grips do nonchange into Distort, the grips will distort the distort with the corner grips, but you can also add more control points on the sides of the bounding box, and have even more power to distort.

Change the Color Wheel into black, and then paintdisplay where there was already content, so we’ll paint the exact silhouette of the tree. Dropping a shadow can add a lot of depth to 2D images.

10. We may want to have both the tree and its shadow as one Down. Make sure the layer for the tree is over the layer for the shadow. Please also note that the name of the new layer will default to Paint#. We will need to rename the layer.
