Video: Using image and canvas controlsIn this lesson I'll show you how to select and adjust your image and canvas controls in SketchBook Pro. Let's begin by going to the main menu bar and clicking on the Image tab and select Image Size. A window will appear allowing you to adjust image size by pixel percentage and document size. The reasons for these adjustments are sometimes driven by resolution demands for both print and electronic media. For our purposes, we'll direct our image by document size and resolution. One small detail I'd like to mention. In this lower left-hand corner, there's an open box named Keep proportions.

Using image and canvas controls
In this lesson I'll show you how to select and adjust your image and canvas controls in SketchBook Pro. Let's begin by going to the main menu bar and clicking on the Image tab and select Image Size. A window will appear allowing you to adjust image size by pixel percentage and document size. The reasons for these adjustments are sometimes driven by resolution demands for both print and electronic media. For our purposes, we'll direct our image by document size and resolution. One small detail I'd like to mention. In this lower left-hand corner, there's an open box named Keep proportions.
Unchecking this box allows you to openly resize your document. In this particular demonstration, I'd like to go ahead and keep my proportions. And this particular drawing is 12 inches wide by 9 inches high at 100 dpi resolution. I'm going to go ahead and click the OK button. And this is what we're going to be working with. Next, are the Canvas Controls. A good way to think of this function is that it allows for your drawing to be adjusted in many ways.
To begin, let's return to the main menu bar. Click on Image and click on Canvas Size. The default setting will show the current image size. Now currently the image is in pixels. So let's go ahead and click on the first tab. And look at our options. Let's go ahead and select inches. And you can see it's the same dimensions as our image size. Changing these sizes greater than the image size will allow your picture room for the addition of a border, tile area or simply room that accommodates a framing mat. So let's go ahead and do that.
Let's go ahead and select that by pressing down and sliding to the left. And let's go head off your keyboard. Enter a larger number. Now you see how it's independent of the Height? Let's go ahead and adjust the Height to 12. Click OK. Now what you have to do is just go to the interface lagoon to your Move and Zoom tool. Zoom-out and you can see how before, remember, we had a more horizontal format and now we have a format that's becoming more square. However, the image itself did not change. Now let's go ahead and do something a little different.
Let's go ahead and reduce the size of our Canvas and see what we have. So let's go back to the main menu. Select Canvas Size. Let's go to the first bar where it says Width. Let's convert everything back to inches. And do you all remember what that last dimension was? I believe it was 12 inches wide by 9 inches high. So let's go ahead and reduce this Width down to 6 and Height down to 3. Now you see what happened? Let's go ahead and undo this so you can see where we were. We were 14x12 and then we went to 6x3.
Look what happened. You see that's an extreme situation where if you reduce the number greater than the image size, you have extreme cropping. So it will use a lot of your image. But thanks to Image Canvas SketchBook Pro, you'd just simply go back to Undo and Undo again to return to your original image size. That's basically resizing the canvas. Let's now move to the next control, which is Rotate Image Counterclockwise. Going back to the main menu, select Rotate Image Counterclockwise, and watch what happens.
You see how the whole image rotates up to the left? Now let's go ahead and rotate the image clockwise to return it to where it was. Now you can also mirror the canvas. Keep your eye on the middle of your canvas. Can you see how things have flipped? Now not only can you flip that 180, but you can also flip it Vertically 180 by Flipping Canvas Vertically, things flip upside down. So let's go ahead and flip that back, mirror the canvas back to the original position. Now that you have an idea of how image in canvas controls work, you're now ready to draw and paint in SketchBook Pro.
