Parameters
- g
- The destination Graphics object.
- image
- Pointer to an object that references the image to be painted.
- src
- Rectangle that specifies the part of the image to use as the display source.
- srcClip
- Rectangle that specifies the portion of the display source to paint. Generally, this is used for updating the display when part of the source image has changed.
- dest
- 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 Rectangle object.
- destClip
- 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 for the Rectangle object are relative to the device context. You can pass null to use the default, which matches the device context.
- paintProperties
- Options for the display.
- effectType
- Effect to apply when painting. For valid values, refer to SpecialEffectsType.
- progressCallback
- Callback method that will be called when the paint image effect is started to determine the status for the paint of the image effect.
This example shows the minimum requirements for using PaintImageEffect method to paint an image .

If the screen has fewer colors than the image, this method dithers the output to that display surface without affecting the actual image data.
PaintImageEffect paints an image faster if its view perspective is bottom left. LEAD CMP images have a bottom-left view perspective, but some other formats have a top-left perspective. To get uniformly fast paints on all images, you can set the perspective after you load them. (You do not have to change them back before saving them in the original format, because the save methods set the orientation for the specified format.)
Multipass painting for the PushClass is disabled.
