3D Filters
The three-dimensional filters in CorelDRAW 9 transform images to create the illusion of three-dimen sional
depth.
Cylinder : The Cylinder filter warps an image around the shape of a cylinder. The Percentage slider lets use rs
specify the amount of wrapping. Positive values expand pixels, while negative values compress pixel s.
Sphere : The Sphere filter wraps an image around the inside or outside of a sphere. The Percentage slider lets
users control the effect. Positive values expand the central pixels towards the image’s edge, resul ting in a
spherical shape. Negative values compress pixels towards the center of the image to conform the ima ge to a
concave sphere.
Blur Filters
The filters in the Blur flyout menu alters an image to soften, smooth edges, blend, or create motio n effects.
Low Pass: The Low Pass filter removes sharp edges and detail from an image, leaving smooth gradients and
low-frequency detail. Users can control the percentage and radius of the effect using the sliders.
Jaggy Despeckle: The Jaggy Despeckle filter scatters color in an image, creating a soft, blurred effect with
minimal distortion. Users can control height and width values of the effect.
Directional Smooth: The Directional Smooth filter analyzes the value of pixels of similar tonal values to
determine the direction in which to apply the greatest amount of smoothing, subtly smoothing edges and
surfaces.
Zoom: The Zoom blur filter lets users create an effect that blurs pixels outward from a center point on an
image. The pixels closest to the center point are the least blurry. Users can customize the amount of blurring.
Radial Blur: The Radial Blur filter gives an image a blurred effect that radiates out from a central point. Use rs
can reposition the center point, set the intensity of the effect, choose a blur node, and set the q uality of the
output.
Soften: The Soften filter slightly blurs an image, retaining a high level of detail. Users can apply the S often filter
to the entire image, or to part of it using a lens.
Color Transform Filters
Bit Planes: The Bit Planes filter is a powerful tool for analyzing gradients in images. It reduces the image t o
basic Red Green Blue (RGB) components and emphasizes tonal changes. The Bit Planes filter is useful for
analyzing the number of steps in gradients.
Halftone: The Halftone filter gives an image the appearance of a color halftone, which is an image that has
been converted from a continuous tone image to a series of dots of various sizes to represent diffe rent tones.
Users can adjust the screen angles to produce a wider range of colors.
