Applying Artistic Effects

The following command classes are designed specifically for artistic effects:

Class	Purpose
AddNoiseCommand	Adds random pixels to an image, letting you specify the percentage of coverage and the color plane.
AgingCommand	Adds effects that simulate random color changes, scratches, dust and pits, making an image look like it was made from an old film.
AlphaBlendCommand	Combines two images with a fixed opacity value to create a new blended image.
BendCommand	Wraps the image along the inside or outside of an arc pattern.
BricksTextureCommand	Creates a brick texture that makes an image look like it has been drawn on a brick wall.
BumpMapCommand	Combines an image with a bump image to create a three-dimensional texture pattern.
CanvasCommand	Combines two images, superimposing one image on another image that is used like a canvas.
CloudsCommand	Generates randomly different clouds patterns.
ColoredBallsCommand	Throws colored balls over the image. The resulting color of the ball is a combination of ball color and the color of the pixel where it has fallen with certain opacity.
ColoredPencilCommand	Applies an effect to an image that makes it look like it has been drawn with colored pencils.
ColoredPencilExtendedCommand	Like ColoredPencilCommand, this function applies an effect to an image that makes it look like it has been drawn with colored pencils. However this function has more parameters, like ones for paper roughness, pencil stroke length, pencil roughness, etc.
CylinderCommand	Warps the image to a cylindrical shape.
DiceEffectCommand	Splits the image into square or rectangular blocks. If the blocks are square, rotates each block by 0, 90, 180, or 270 degrees. If the blocks are rectangular, flips the blocks around the X-axis and Y-axis.
DiffuseGlowCommand	Adds a colored glow to an image's light or dark areas, making these areas shine with a neon glow.
DryCommand	Simulates painting an image with the watercolor dry brush technique.
EmbossCommand	Applies an emboss effect to an image, letting you specify the depth and direction of the effect.
FadedMaskCommand	Creates a fade mask image.
FeatherAlphaBlendCommand	Combines two images with feathering by using a variable opacity that depends on a fade mask.
FreeHandShearCommand	Shears the image by the wave drawn using specified amplitude values.
FreeHandWaveCommand	Distorts the image by the wave drawn using specified amplitude values.
FreePlaneBendCommand	Wraps the image onto a 3D plane shaped by a Curve.
FreeRadialBendCommand	Wraps the image along its radius on a 3D surface shaped by a Curve.
GlassEffectCommand	Divides the image into rectangular cells and makes it look as if it is being viewed through glass blocks.
GlowCommand	Makes the colored edges shine with a neon glow.
LensFlareCommand	Simulates the secondary reflections caused when bright lights are facing the camera lens. The lens flare is refracted into a series of lightened circles that surround the flare.
LightCommand	Adds light to the image according to a method-based distribution. This method al light will be generated by one of the following methods: linear, quadratic, sine, cosine, or using freehand points.
ImpressionistCommand	Makes an image look like it was painted by an impressionist painter.
MosaicCommand	Imposes a mosaic effect on an image by dividing the image into tiles of a specified size and changing the color of all pixels in each tile to the average color of pixels within the tile.
MosaicTilesCommand	Creates a mosaic effect on an image by dividing an image into rectangular or arc-shaped cells with irregular boundaries and modifying the color of each cell.
MotionBlurCommand	Applies a filter, which creates the illusion of movement in an image.
OceanCommand	Reflects the image on an ocean surface.
OilifyCommand	Applies an oil-painting effect to an image.
PerlinCommand	Uses a pseudo-random number generator in order to create a Perlin noise, and then procedurally transforms that noise into a texture.
PicturizeListCommand	Replaces an image with a new image created by combining images present in a list.
PicturizeSingleCommand	Picturizes an image using various versions of a single image.
PixelateCommand	Divides the image into rectangular or circular cells and then recreates the image using those cells filled with the minimum, maximum, or average pixel value, depending upon the effect that was set.
PlaneBendCommand	Places the image on parallel planes along the Z-axis, and bends the planes toward the center point.
PlaneCommand	Places the image on parallel planes along the Z-axis.
PlasmaCommand	Applies color patterns that blend into each other like plasma.
PointillistCommand	Converts image colors into randomly placed dots to create a pointillist painting.
PolarCommand	Converts the image from rectangular to polar coordinates and vice versa.
PosterizeCommand	Imposes a poster effect on an image by quantizing the image's colors to a specified number of color levels per plane. For example, two levels means two of red, two of green, and two of blue.
PunchCommand	Warps the image by pinching it toward the center or expanding the image away from its center.
PuzzleEffectCommand	Splits the image into square blocks and randomizes these blocks inside the image.
RingEffectCommand	Divides the image into a certain number of rings. Each ring is rotated according to a rotate angle. The rotate angle for each ring will be chosen randomly by the method or can be passed to the method.
RadialBlurCommand	Rotates the image pixels around a center point.
RadialWaveCommand	Distorts an image using a wave radiating from the specified center.
RevEffectCommand	Adds a pseudo-3D wave effect to the image by drawing horizontal lines across the image and basing each line height at each point on its brightness at that point.
RemoveRedeyeCommand	Replaces the red component of the pixels with the specified color. To replace only the red component for those pixels in the eyes of the image, select a small region around the eye(s).
RippleCommand	Warps the image in concentric rings.
RomanMosaicCommand	Segments the image into rectangular or rounded rectangular tiles and fills them with a color chosen randomly from the colors of the tile's pixels.
SegmentCommand	Divides the image into segments where each segment pixels have approximately the same color (homogenous color).
ShadowCommand	Adds shadows to an image, letting you specify the threshold value, the direction of the light source, and whether the shadows are colored or grayscale.
SphereCommand	Warps the image around a 3D spherical shape.
SwirlCommand	Produces a swirl pattern by rotating the image the specified number of degrees about the specified point.
SolarizeCommand	Applies an effect that mimics the accidental exposure of photographic film to light.
TextureAlphaBlendCommand	Combines image data from two images with an underlay effect. The result is used as a fade mask that will be used to combine the two images with variable opacity. The result is combined again with the destination image using a constant opacity.
TunnelCommand	Places the image inside a tunnel along the Z-axis.
Underlay	Combines two images so that one appears to be an underlying texture for the other.
WaveCommand	Distorts the image with two perpendicular waves at the specified angle and with the specified wave type.
WindCommand	Creates thin lines, directed along the specified angle, on the specified image.
ZoomBlurCommand	Blurs the image along radial lines starting from the specified center point.
ZoomWaveCommand	Distorts the image with a wave zoomed from the specified center.

With any of these methods, except Underlay, you can limit the effect to a specified region of interest. For information about regions, refer to Defining and Using a Region.

Treating the image as a device context opens up many possibilities for artistic effects. The CreateLeadDC method lets you get the device context. You can then use the LEADTOOLS special effects command classes to combine images in interesting ways. For example, when painting one image on top of another, you could specify a multi-pass paint with a brush effect; then quit before finishing all of the passes. The result would be a blending of the two images.
