As always, we will be using Pixels as our units of measure. Right click on the screen and select Page Options... from the pop up menu. In the Units tabbed section, select Pixels for the Units and 0-255 for the Color Units. In the Grid and Ruler tabbed section set the Major Spacing to 100pix (key it in exactly like this please) and the Number of Subdivisions to 10. Press OK to close the dialog and apply the changes. NOTE: You will notice from time to time I apply arbitrary colors to objects. I do this to make the objects easier to see. If I do not specify a fill for an object, you do not have to apply a fill or outline color. When I show an ellipse or rectangle that has just been created, that has no fill, it is because I have set the fill to none before I exported the illustration. By default, all ellipses, rectangles and Quick Shapes have a black outline and a black fill. There is nothing wrong with your copy of Xara. Naming Conventions. I use bold face to indicate the names of tools, galleries, keyboard shortcuts, and dialogs. Items such as unnamed icons and drop down lists, which have names when you let your cursor rest over them for a moment, are displayed in italics. The Infobar is the context sensitive menu at the top of the screen and changes to reflect the options for the selected tool. New Users? I have created some quick start mini-tutorials to get you though the basics. Workbook 20, Workbook 30, and Workbook 31 cover the main things you need to know to get started. While you should be able to create all the steps in previous versions of Xara, some of the tool icons have changed, and this may cause some confusion for new users. If you are using an older version of Xara, click here to see my Rosetta Stone for translating the old buttons into the new. |

A quick Stereogram demo Humans see in stereo vision. The left eye and the right eye see a slightly different version of the same scene. Objects that are closer to our vantage point will be further apart in terms of left eye and right eye perception. As things move farther away from us the distance is less. Our brain uses this information to determine the depth of what we are looking at. We will use this theory to create this months image. For those who cannot see 3D Stereograms (there are a lot of you), here are some exercises to get you up to speed. Look at the 2 circles above for a few moments, or longer if need be. Relax your eyes to the point of blurring your vision and the 2 circles should look like 3. When this happens you will be in Stereogram viewing mode. Looking at Stereograms actually requires us to focus more in the near distance than close up. So rather than look directly at the circles or the image, try to focus behind the image, as if you were looking at something on the wall behind your monitor. If you look at the circles above for a few moments using the same method used to look at the 2 circles, the black circles should appear to be floating. If you see this, that is good. By altering the spacing between the circles, the light gray circles which are farther apart should appear to be behind the white circles which should appear to be in front of both sets of gray circles. Can you see that? If not, maybe this tutorial is not for you. Remember, your focus should be behind your screen and not at the circles directly. Look at the top 2 circles with the clouds and sky and you should see 3 circles with the same image. Now look at the bottom 2 circles and it should look like the sky in the center circle is some distance behind two circular openings. This is achieved by moving the center of the fill outwards a few ticks in each direction. This is how we will construct the Stereogram for this tutorial.
