TABLE 4. Effects in Photo-Paint 9 continued -
Sharpen, Texture, Fancy and Others.
New effects are marked (*). The entire effects menu has been rearranged in alphabetic order. The thumbnails showing these effects are probably not really appropriate to clearly show the effect. Sorry about that. The best thing to do is to get yourself a copy of PP9 and try them out for yourselves. In almost all cases there are many variations and multiple slider controls for each effect. Most of those shown here are merely the default settings for each effect. Literally hundreds of thousands more are possible using individual adjustments for each effect.

 Sharpen
 Filters
Sharpen filters increase the contrast between the pixels in your image to improve the focus and enhance edges. To optimize the effects you create using sharpen filters, Corel PHOTO-PAINT provides a special control dialog box that lets you access the sharpen effects. You can access this dialog box by clicking Effects, Sharpen, Tune. The sharpen filters are:
  Tune Sharpen provides access to the five sharpen filters (below) at once  
  Adaptive Unsharp accentuates edge detail by analyzing the values of neighboring pixels. This filter preserves most image detail but its effect is apparent in high-resolution images. The Adaptive Unsharp filter is similar to the Unsharp Mask filter.
  Directional Sharpen analyzes pixels near an edge to determine the direction in which to apply the greatest amount of sharpening. This filter enhances the edges of an image without creating a grainy effect.
  High Pass removes low-frequency areas and shading. This filter can give an image an ethereal, glowing quality by emphasizing its highlights and luminous areas.
  Sharpen accentuates the edges in the image by increasing the contrast between their adjacent pixels
  Unsharp Mask accentuates edge detail and focuses blurred areas in the image but does not remove low-frequency areas
   
 Texture  Effects Texture special effects filters let you add texture to your image using a variety of shapes and surfaces. You can use bricks, bubbles, canvas, elephant skin, plastic, and stone; or you can create etchings and underpaintings. You can also use these filters to make your image look as though it were painted on a plaster wall or as though you are viewing it through a screen door. The texture filters are:
  Brick Wall groups pixels into a series of interlocking cells to give images the look of a painting on a brick wall
  Bubbles creates a bubbling foam on your image
  Canvas applies a textured surface to an image by letting you use a secondary image as a canvas
  Cobblestone divides images into cobblestones
  Etching transforms your image into an etching
  Elephant Skin gives images a wrinkled effect by creating an overlay of wavy lines
  Plastic makes your image appear as though it is made out of plastic
  Plaster Wall redistributes pixels to create the appearance that your image has been painted on a plaster wall
  Relief Sculpture transforms your image into a relief sculpture
  Screen Door makes it appear as though you are looking at an image through a screen door
  Stone gives your image a stone texture
  Underpainting makes your image look like a painting done on a canvas that is subsequently covered with layers of paint
   
 Fancy
 Filters
Fancy special effects filters take special effects one step further by allowing you to use fractals and kaleidoscope-like designs from elements within your image.
The fancy filters are:
  Julia Set Explorer 2.0 lets you create and explore Julia Set fractals that you can apply to your image. Fractals are textures created with algorithms and are characterized by irregularity. Their effect on an image can be stunning. The Julia Set Explorer filter lets you use preset fractals or create your own; experiment with the controls to get the most from this effect.
  Terrazzo allows you to create kaleidoscope-like designs using elements in your image. This filter crops a portion of your image into a simple shape and repeats, reflects, or flips it several times in interlocking symmetrical patterns over the surface of your image.
   
 Others Squizz 1.5 Squizz allows you to warp or 'pixel push' sections of your image with a brush, or to specify distortions to different sections using a grid overlay.
