Parameters

hdc

The destination Windows device context handle where the image data will be displayed.

srcRect

A Rectangle object that specifies the part of the image to use as the display source.

The coordinates in the srcRect rectangle are relative to the image. You can pass Rectangle.Empty to use the default, which matches the image.

srcClipRect

A Rectangle object 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.

The coordinates in the srcClipRect rectangle are relative to the image. You can pass Rectangle.Empty to use the default, which matches the image

destRect

A Rectangle object that determines how the source rectangle is scaled and how the image is positioned in the destination hdc handle.

The coordinates in the destRect object are relative to the hdc handle. There is no default for this parameter. You must specify the Rectangle object.

destClipRect

A Rectangle object 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 destClipRect are relative to the device context handle. You can pass Rectangle.Empty to use the default, which matches the device context handle. In most cases, however, you should use the rectangle returned by the .NET PaintEventArgs.ClipRectangle or Windows WM_PAINT message.

properties

Options for the display.

This method works the same as Paint, except that only the image region is painted.
