Resize an object on a canvas

Resize the headlight on an image of a car.

This "How-To" uses the file bmw.tif as an example. The file is located in the pix sub-directory in the Courseware project.

Open it by choosing File > Import > Canvas image .

Copying the headlight

First, copy the detail you want to resize; in this case, copy the headlight.

To copy the headlight

Zoom and pan your view so you can see the left headlight clearly.



Choose Paint > Select > Marquee (rectangle) .
Drag a rectangle around the left headlight.



If you make a mistake, drag a new rectangle around the headlight.

The pink color indicates regions of the active layer that are not selected. (Regions that are not selected are also referred to as masked regions.)

Regions that are not pink are selected regions (or unmasked regions).

Now you can only modify the selected regions (for example, painting, erasing, copying, and so on).

You cannot modify the pink (masked) regions.

Choose Edit > Copy image to copy the selected regions to the clipboard.
Choose Windows > Editors > Canvas Layer editor to open the Canvas Layer Editor.
Double-click on the layer containing the image, and rename it bmw (if not already the case).
Choose Edit > Paste image to paste the contents of the clipboard into a new image layer.

Notice in the Canvas Layer Editor window that there is now a new layer named ALIAS_PIX_CL.

Double-click the ALIAS_PIX_CL layer, type headlight and press to rename the layer.

Resizing the headlight

Next you'll resize the headlight.

To remove paint around the headlight

In the Canvas Layer Editor window, click the icon for the bmw layer to hide the image layer. Now you can clearly see the contents of the headlight layer.



Make sure the headlight layer is active. It should be highlighted in purple. If it is not, click it.

In the Canvas Layer editor, click the new invisibility mask layer button.
Click on the headlight layer again to make it active.
Link the invisibility mask layer (Invisibility-#)to the headlight layer by clicking the icon to the right of the invisibility mask layer name so that it becomes a icon..



Click on the invisibility mask layer to make it the active layer.
Choose Paint > Solidbrush > Brush Felt.

Adjust the size of the brush to give you control, and paint the car areas. Notice that where you paint, a mustard-yellow color is laid down. This will hide the parts of the car that you don't want visible.

Brush roughly around the headlight to hide most of the car body.



If some of the headlight is covered by the yellow invisibility mask, use the eraser tool to remove the mask in those areas.

Brush carefully around the headlight to hide any remaining parts of the car body, adjusting the size of the brush and eraser as needed.



Click on the Headlight layer to see how the Invisibility mask layer hides all areas covered in yellow.



In the Canvas Layer Editor, click the icon for the bmw layer to show it again.
