Parameters

type

Type of DIB to create. Possible values are:

Value	Meaning
RasterConvertToDibType.BitmapInfoHeader	DIB that uses a BITMAPINFOHEADER
RasterConvertToDibType.BitmapV4Header	DIB that uses a BITMAPV4HEADER. (Introduced in Windows 95 and Windows NT 4.0)
RasterConvertToDibType.BitmapV5Header	DIB that uses a BITMAPV5HEADER (Introduced in Windows 2000 and Windows 98)

Return Value

A DIB consists of one of the following:

• a BITMAPFILEHEADER,
• a BITMAPV4HEADER (introduced in Windows 95 and Windows NT 4.0),
• or a BITMAPV5HEADER (introduced in Windows 2000 and Windows 98),

followed by a color table and then the bitmap data. The resulting DIB type is determined by the value of the type parameter.

The orientation of the image and color order will depend on how the image was loaded into the RasterImage.

When you no longer need the DIB, you can free it using the Windows GlobalFree function.

This method does not support signed data images. It will throw an exception of type RasterException with code value RasterExceptionCode.SignedDataNotSupported if this RasterImage has a signed data image.
