In this lesson, we are going to see how we can create what's called a zoom area in Captivate. This is an area that allows us to emphasize certain areas of our slides by making them larger and providing some animation. We will be using the Chapter 5_e file that we created in an earlier part of this chapter. If you don't have it open, please open it now and then go to slide number 4. I would like to emphasize the first quarter of this slide. I'm going to do it by using what's called a zoom area. I can insert a zoom area from my toolbar, right here, looks like a magnifying glass.
Select it and you'll see that we get two objects that will automatically appear on the Timeline. One of them is my zoom source, and the other is the amount of time that will be displaying. Now this is an animated feature, so the zoom is going to start in the original location and then it's going to grow to the destination location. That's why there is two squares here. The blue one is the area that's going to be magnified. Let's adjust that first. Select the zoom source and then move it over to this side of the graph.
You can see that the zoom destination has already updated. Drag down so that you can see all of the Q1 results. This will include some of the Q2 results, and that's okay. We will need to change the zoom destination to make it larger. You can see right now that it's actually reducing the content to fit into the smaller area. If we hover over, we can see that we have 197 x 275 as our dimensions. We will want to try and preserve these proportions if we can.
Select the zoom destination and drag it into the upper right-hand corner of this page. Grab the lower left-hand corner and drag it towards the middle. Look at your Position and Size. You can enter in precise values for the width and height of the zoom destination. You can also do this with a zoom source. If we select the zoom source and then open up Position and Size, we can see that it's 197 x 275. Let's make this easy to calculate by making it to be 200 wide.
We will change the height to 280. Before we type our change, however, we've got to uncheck Constrain proportions. Otherwise, when we change this to 280, this is likely to increase to 201. Select and type "280" and then Return. Select the zoom destination, and what we're going to do is to magnify by 50%. That means that the width is going to have to be 200 times 1.5, which would be 300.
And the height is going to have to be 1.5 times 280. We will need to shut off Constrain proportions to be able to get at that number. 1.5 times 280 is 420, so we can enter that number right here. Now we have the same proportions between the zoom source and the zoom destination. Let's turn our Constrain proportions on again, and we will move this over here so it fits in this space.
We can control the width of the outside stroke. By default, it's kind of pink and has a 1-point width. Let's set it to be 3 points wide and change it to blue. We will do the same with the zoom source: change its outline to be blue and set its stroke to be 3 points wide. Great! Let's preview the results. We will use preview from this slide.
You can see that zooming animation takes place, but it goes away very quickly. I would like the slide to last a little bit longer. We can adjust the amount of time it takes to zoom by dragging this bar that's in the middle of the zoom area on the Timeline. Click and drag it to the left to shorten the amount of time it takes to zoom and extend the amount of time that it lasts on stage. Let's make the entire duration of the slide five seconds. We can do that by dragging the slide duration here to the right to five seconds.
Click and drag and pull it out to five seconds. Let's move this Click Box to the end as well. Select the Click Box and drag it all the way to the end of the slide. That red arrow tells us that the Click Box has been pinned to the end of the slide. Let's preview one last time, and then we'll save our project. We will preview from this slide again. Now you can see that the zoom is hanging on for a longer period of time.
I've noticed that the zoom area is disappearing at the end of the slide. Let's fix that by changing the transition. Select the zoom source and change our Effect to No Transition. Now that we've made that change, let's save it as Chapter5_f. Zoom areas can be an effective way for you to emphasize specific content in your Captivate projects.
An important thing to remember though is that you want to maintain the proportions between the zoom source and the zoom destination. Your content in your zoom destination will distort if you don't maintain the proportions between the source and the destination. It's always good to keep a calculator handy when using the Zoom Area tool.
