Quick links to procedures on this page:
The distort special effects transform the appearance of images without adding depth.
The Blocks effect breaks down the image into scrambled block pieces. You can specify the size of the blocks, the distance between the blocks, and the color of the background (exposed when the effect is applied).
The Displace effect shifts an active image according to the values of a secondary image known as a displacement map. Values from the displacement map display as forms, colors, and warp patterns in the image.
The Mesh warp effect lets you distort an image by repositioning the nodes on a superimposed grid. You can increase the number of nodes on the grid by increasing the number of gridlines to a maximum of 10. Increasing the number of nodes on the grid provides finer control over small details in the image. You can use any of the preset mesh warp styles, and you can create and save custom mesh warp styles.
The Offset effect changes an image’s position by shifting it according to the parameters you specify. When an image is offset, empty areas display where the image was previously positioned. You can fill the empty areas by tiling or stretching the image, or by applying color.
The Pixelate effect breaks an image into square, rectangular, or circular cells. The Pixelate effect is also a preset lens type.
The Ripple effect distorts an image with one or more waves. You can specify the strength of the primary wave to set the warping of the image or add an additional perpendicular wave to increase the distortion.
The Shear effect (Effects 
Distort Shear) maps the shape of an image to the shape of a line segment.
The Swirl effect creates a swirl across an image according to the direction, number of whole rotations, and angle that you specify.
The Tile effect reduces the image’s dimensions and reproduces it as a series of tiles on a grid. You can use this effect in combination with a flood fill to create a background or to create a wallpaper effect for a webpage.
The Wet paint effect creates the illusion of wet paint on images. You can specify the size of the drips and the range of colors that are affected in the image.
The Whirlpool effect applies a fluid, swirling pattern across an image. You can use a preset whirlpool style, or you can create a custom style by setting the smear length, spacing, twist, and streak detail of the effect. You can also save custom whirlpool styles.
The Wind effect blurs an image in a specific direction, creating the effect of wind blowing across the image. You can specify the strength and direction of the blur, as well as the transparency of the effect.
