Rotating images
Canvas gives you the ability of applying a soft rotate or hard rotate to your images. A soft rotate is
sufficient if you do not need to export the images to another format; however, if you plan on
exporting your images and need them to remain rotated, then you should apply a hard rotate. A hard
rotate not only rotates the image but also adds white pixels to the bounding box. Soft rotate does not
add pixels.
Anti-aliasing for rotated bitmaps
Sometimes bitmap images can lose their clarity when they are rotated. The anti-aliasing for rotated
bitmaps feature addresses this issue. If you’re rotating a bitmap and select Hard rotate for image in
the Rotate dialog box, the Anti-alias image check box becomes available. The anti-aliasing option
results in a smoother, better quality image.
To hard rotate an image with the Rotate dialog box:
1. Choose Effects | Rotate Right or Rotate Left | Other.
2. Make sure you select Hard rotate for image to enable Anti-alias image.
