Parameters

hdc

The destination device context where the image will be displayed.

index

The index of the overlay used for painting. The overlay should have an image. If the overlay is embedded into an image bitplane, make sure you create an overlay image prior to calling this method. This index is zero-based.

srcRect

Rectangle which determines the portion of the image to paint.

srcClipRect

Rectangle which further clips the source image.

destRect

Rectangle which determines where the image is placed, and how it is scaled.

destClipRect

Rectangle which clips the image display.

properties

Options for the display.

This method will paint an overlay image. For more information on the paint rectangles, see Paint.

Paint will paint all the overlays that have RasterOverlayAttributes.AutoPaint set to true. The overlays are painted in ascending index order: overlay 0 is painted first, then overlay 1, etc.

Use this method to manually paint an overlay. For example, to change the order in which the overlays are painted, set the RasterOverlayAttributes.AutoPaint property of the overlay to false then call PaintOverlay directly.

To temporarily make an overlay top-most, call PaintOverlay after Paint. To permanently make an overlay top-most, change its index and give it the highest defined index.

The overlay image's 1 pixels are painted with the color set in the RasterOverlayAttributes.Color property of the overlay. The overlay image's 0 pixels are considered transparent.

For more information on the overlay attributes, including the RasterOverlayAttributes.AutoPaint property and the RasterOverlayAttributes.Color property, refer to RasterOverlayAttributes.

For more information, refer to Overlay Overview.
