Changing image size You can use several methods to resize or scale paint objects and the images they contain. Keep in mind that altering the size or resolution of a paint object can degrade the quality of an image. Canvas uses interpolation to esti- mate pixel values when necessary, but this can result in loss of sharp- ness or detail when large scaling factors are applied. The best way to avoid image degradation is to avoid changing image size or resolution. •   If an image is too big for a particular layout, consider crop- ping the image, rather than resizing or scaling it to fit. •   If a photographic image requires higher resolution, try re- scanning the original at a higher resolution, rather than increasing the resolution in Canvas. If you resize, skew, or rotate a paint object, you can restore the origi- nal shape and resolution by choosing Effects > Remove Effects. Stretching images with the mouse You can change the size of a paint object by clicking it with the Selection tool and dragging a selection handle. Stretching an image non-proportionately also stretches the pixels, which can cause unwanted distortion to the image. Scaling images using the Scale command You can change the size of a paint object by selecting it and choosing Scale in the Object menu. The Scale command lets you maintain the object’s proportions, or distort an image by scaling it in one direction. Using the Scale command does not add or remove pixels from an image. For information on using Scale, see “Scaling objects” on page 16.275. Tip You can also remove effects via the Undos palette or by using the keyboard com- mands: Command+Z (Mac) or Ctrl+Z (Windows).
