Applying Artistic Effects

The following methods are designed specifically for artistic effects:

Method	Purpose
AddNoise	Adds random pixels to a bitmap, letting you specify the percentage of coverage and the color plane.
AddShadow method	Adds shadows to a bitmap, letting you specify the threshold value, the direction of the light source, and whether the shadows are colored or grayscale.
Aging method	Adds effects that simulate random color changes, scratches, dust and pits, making a bitmap look like it was made from an old film.
Bending method	Wraps the bitmap along the inside or outside of an arc pattern.
Cylindrical method	Warps the bitmap to a cylindrical shape.
DiceEffect method	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.
Emboss method	Applies an emboss effect to a bitmap, letting you specify the depth and direction of the effect.
FreeHandShear method	Shears the bitmap by the wave drawn using amplitude values obtained from GetCurvePoints.
FreeHandWave method	Distorts the bitmap by the wave drawn using amplitude values obtained from GetCurvePoints and a specified angle.
FunctionalLight method	Adds light to the bitmap according to a function-based distribution. This functional light will be generated by one of the following methods: linear, quadratic, sine, cosine, or using freehand points.
Impressionist method	Makes a bitmap look like it was painted by an impressionist painter.
Mosaic method	Imposes a mosaic effect on a bitmap by dividing the bitmap 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.
MotionBlur method	Applies a filter, which creates the illusion of movement in an image.
Oilify method	Applies an oil-painting effect to a bitmap.
Pixelate method	Divides the bitmap 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.
Polar method	Converts the bitmap from rectangular to polar coordinates and vice versa.
Posterize method	Imposes a poster effect on a bitmap by quantizing the bitmap'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.
Punch method	Warps the bitmap by pinching it toward the center or expanding the bitmap away from its center.
PuzzleEffect method	Splits the image into square blocks and randomizes these blocks inside the image.
RingEffect method	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 function or can be passed to the function.
RadialBlur method	Rotates the bitmap pixels around a center point.
RadWave method	Distorts a bitmap using a wave radiating from the specified center.
RevEffect method	Adds a pseudo-3D wave effect to the bitmap by drawing horizontal lines across the bitmap and basing each line’s height at each point on its brightness at that point.
RemoveRedeye method	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 bitmap, select a small region around the eye(s).
Ripple method	Warps the image in concentric rings.
Segment method	Divides the bitmap into segments where each segment’s pixels have approximately the same color (homogenous color).
Spherize method	Warps the image around a 3D spherical shape.
Swirl method	Produces a swirl pattern by rotating the bitmap the specified number of degrees about the specified point.
Solarize method	Applies an effect that mimics the accidental exposure of photographic film to light.
TextureAlphaBlend method	Combines image data from a mask bitmap and an underlay bitmap with an underlay effect. The result is used as a fade mask that will be used to combine a source bitmap and a destination bitmap with variable opacity. The result is combined again with the destination bitmap using a constant opacity.
Underlay	Combines two bitmaps so that one appears to be an underlying texture for the other.
Wave method	Distorts the bitmap with two perpendicular waves at the specified angle and with the specified wave type.
Wind method	Creates thin lines, directed along the specified angle, on the specified bitmap.
ZoomBlur method	Blurs the bitmap along radial lines starting from the specified center point.
ZoomWave method	Distorts the bitmap with a wave zoomed from the specified center.
BumpMap method	Adds a three-dimensional texture pattern by applying the bump image to the destination image.
Cubism method	Remaps the bitmap into a collection of rotated rectangles (cubic faces), in the Cubist style.
DrawStar method	Draws a star on the bitmap.
Dry method	Simulates painting an image with the watercolor dry brush technique.
FreePlaneBend method	Wraps the bitmap onto a 3D plane shaped by pnCurve.
FreeRadBend method	Wraps the bitmap along its radius on a 3D surface shaped by pnCurve.
GlassEffect method	Divides the image into cells and makes it look as if it is being viewed through glass blocks.
GlowFilter method	Makes colored edges shine with a neon-like glow.
LensFlare method	Simulates the secondary reflections caused when bright lights are facing the camera lens.
Light method	Adds many spots of directed light sources to the bitmap.
LightControl method	Lightens or darkens all or part of a bitmap by remapping the pixel values.
Ocean method	Reflects the bitmap on an ocean surface.
PlaneBend method	Places the bitmap on parallel planes along the Z-axis bent towards a center point.
Plane method	Places the bitmap on parallel planes along the Z-axis.
SampleTarget method	Corrects color values by shifting the sample colors to the target colors.
SmoothEdges method	Smoothes the rough edges in the bitmap.
Tunnel method	Places the bitmap inside a tunnel along the Z-axis.

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