Redraw is the process of Xara X building up the on-screen image from the information stored about the drawing. Some operations redraw automatically as you work, such as modifying a color. Others only redraw when you press Enter on your keyboard. On older computers with limited memory, you can limit the amount of memory Xara uses to redraw the entire screen in the Page Options > Tune-ups tabbed section. TIP: Some graphics cards leave bits of images on the page called artifacts. These do not print, nor can they be selected and deleted, but they are annoying nevertheless. Should these occur, press the Zoom to Previous icon on the Infobar twice. When you return the artifacts will be history.
Rectangle Tool Infobar The Infobar is a special control bar which changes depending on which tool you have selected. See WebXealot 25 for a complete review of Infobars for Xara's Tools. Rendering is the process used by Xara X to draw the document on the screen. The term rendering can also be used as a noun and refers to an image that is a rendering of something. Resolution (of bitmaps): some file formats such as JPEG and PNG let you set a resolution (dots per inch or dpi) independently of the physical size of the bitmap. The main use of this is for printed output. A Windows PC monitor has a resolution of 96 dpi, which means there are 96 dots (or pixels) to one linear inch. This is adequate for on-screen work. However 96 dpi is too coarse for printing, which requires 150 dpi or higher. NOTE:
For an in depth discussion of bitmaps and resolution see WebXealot 30.

You can create rollover buttons with any combination of the four states. (Xara X automatically creates the Mouse Off button.) For more information on Xara's Button and NavBar Tool, see WebXealot 19.
To resize an object, select it with the Selector Tool and drag on the control handles (the small black squares). Click twice to enable rotate/skew mode. Drag the corner arrow handles to free rotate the selection, drag the middle arrow handles to skew the selection. Hold down the Ctrl key to constrain the rotation or skew to the amount defined in the General tabbed section of the Page Options dialog.

Rulers are shown at the left-hand side and top of the document window. They let you know which part of the page you are viewing, display the current mouse X,Y position and allow the simple creation of guidelines. To enable rulers, select Window > Bars... Rulers or press Ctrl L. To change the units of measurement for the rulers, right click on a ruler and select Grid and Ruler Options... from the pop up menu. You can drag guidelines from the rulers onto the page. Pull down from the top ruler to add a horizontal guide and drag from the vertical ruler onto the page to add a vertical guide. TIP: You can double click on the ruler to add a guideline in the exact location you clicked. To remove all guidelines at one time, right click on the rulers and select Delete all Guidelines. |

QuickShapes are 'intelligent' shapes
created using the QuickShape, Rectangle and Ellipse Tools. All QuickShapes can be edited in a very flexible manner. For instance, a circular QuickShape can be
converted to a polygon QuickShape with one click using the QuickShape Tool. If you wish to change a QuickShape so it can be edited as a shape built from straight and curved lines, you must
Convert to Editable Shapes (Arrange menu). For more fun with QuickShapes, such as the examples shown here, see 
Radius Creation
If you draw a rectangle, ellipse or QuickShape using radius creation, where you start dragging the mouse sets the center of the shape and where you stop dragging sets the radius (size)
of the shape. For a complete discussion of Radius, Diameter, and Bounds creation, see 
Redo allows you to redo editing operations that have been
Undone. There are several ways to Undo and Redo an operation. The easiest is to click the blue Undo and Redo arrow icons on the Infobar. The arrow facing left is Undo and the arrow facing right is Redo. Ctrl Z
is the keyboard shortcut for Undo while Ctrl Y is the keyboard shortcut for Redo. You can also select from the Edit pull down menu.
Registration Black Some drawing packages have a
special color designation called Registration Black which prints on all film separations. In essence this color is made up of 100% cyan, magenta, yellow and black. Registration black is used for printer's registration marks
that need to appear on each piece of film to permit the printer to register the pieces of film. In Xara X you can specify individual objects that you want to print on all separations.
Right-click on the object to open the pop-up menu. Then choose Print on all plates from the Imagesetting sub-menu. Use Print on all plates with
care. If you use it over large areas, you can flood the printing press with excess ink.
RGB (Red, Green, Blue) is the natural color space for
computers. Colors would usually be defined using this model if they are to remain 'on-screen' - for example if Xara X is being used to create bitmaps for use on the Internet. Colors displayed on your computer monitor and
on television screens are comprised of tiny phosphors of red, green, and blue light which when mixed can create a universe of 16.7 million colors. When all three RGB phosphors are at
maximum intensity, the result is pure white light. When all the phosphors are at 0% intensity, the result is pure black.
Robert's Cross (Bitmap Effect) lightens
edges found in bitmaps. 
Rotation and Skew Selection handles (also referred to as
bounding box handles) operate in two modes - Scale mode and Rotate/Skew Mode. The former allows the selection to be scaled, the latter allows it to be rotated and skewed.

contours and bevels. For more details see the tool in question in the
