Parameters

g

The destination Graphics object.

image

Pointer to an object that contains the image to paint.

src

Rectangle to be used as the display source rectangle that specifies the part of the bitmap to use as the display source. The coordinates in the Rectangle object are relative to the image. You can pass null to use the default, which matches the image.

srcClip

Rectangle to be used as the display source clipping rectangle that specifies the portion of the display source to paint. Generally, this is used for updating the display when part of the source bitmap has changed. The coordinates for the Rectangle object are relative to the image. You can pass null to use the default, which matches the bitmap.

dest

Rectangle to be used as the display destination rectangle that determines how the source rectangle is scaled and how the image is positioned in the device context. The coordinates for the Rectangle object are relative to the device context. There is no default for this parameter. You must specify the Recatangle object.

destClip

Rectangle to be used as the display destination clipping rectangle.that specifies the portion of the display rectangle to paint. Generally, this is used for updating changes in the display surface, such as when a user moves another window, uncovering a part of the image that had been covered up.The coordinates in the Rectangle object are relative to the device context. You can pass null to use the default, which matches the device context.

effectType

Effect to apply when painting. For valid values, refer to SpecialEffectsType.

grain

Graining size. This is the smallest size (pixel width or height) to be updated when painting an effect. Using a small grain makes the painting smoother, but takes longer to paint. Using a large grain makes the painting more coarse, but paints faster. If the effectType parameter is from the Wave class this represents the duration or height of the wave. Valid values are 1 to 256.

delay

Delay between graining steps, in milliseconds.

speed

Speed of the wave. Valid values are 1 to 256. This parameter is valid only if the effectType parameter is from the Wave class.

cycles

Number of cycles or repetitions used to draw the wave. This parameter is valid only if the effectType parameter is from the Wave class.

pass

Pass number when using a pattern brush. Use 1 for painting in one pass.

maxPass

Maximum passes for a pattern brush. Use 1 for painting in one pass.

transparency

True to implement transparency by not painting pixels of the color specified in the transparentColor parameter; False if transparency is not implemented.

transparentColor

Value that specifies the transparent color.

wandWidth

Wand width, in pixels.

wandColor

Value that specifies the wand color.

paintProperties

Options for the display.

progressCallback

Callback method that will be called when the paint image is started to determine the status for the paint image effect.

Use the grain and delay parameters to control the speed of the display. The grain parameter controls the size of the painting increment, and delay controls the time between increments.

The wand is a solid color bar that moves during an effect. Small grain sizes produce the best wand effects. Many of the effects listed in Effect Types can have a wand.

Use the pass and maxPass parameters to paint the image in more than one pass. For example, if you want a 3-pass paint, use maxPass of 3 and paint 3 times, once with pass = 1, once with pass = 2, and once with pass = 3.

Multipass painting for the PushClass is disabled.

If the effectType parameter is from the Twirl class, White Turnover class, Turnover class, Replace class, Laser class, Fade Normal class, Fade Black and White class, Fade Color class or Wave Class, the pass and maxPass parameters have no effect.

If the effectType parameter is from the Fade Normal class, Fade Black and White class or Fade Color class, the grain parameter has no effect. However, if the effectType parameter is from the Wave class, the grain parameter contains the wave size.

If the effectType parameter is from the White Turnover class, the Turnover class or the Replace class, the wandWidth and wandColor parameters have no effect. However, if the effectType parameter is from the Fade Color class, the wandColor parameter contains the bitmap color level.

The speed and cycles parameters have effect only if the effectType parameter is from the Wave class.
