Obtains a string representation of the current instance. Deprecated.
Property Description
DrawAlphaEdgeBlend
Warning: This property is deprecated. Deprecated components of DirectX 9.0 for Managed Code are considered obsolete. While these components are still supported in this release of DirectX 9.0 for Managed Code, they may be removed in the future. When writing new applications, you should avoid using these deprecated components. When modifying existing applications, you are strongly encouraged to remove any dependency on these components.
Supports alpha blending around the edge of a source color-keyed surface. Used for draw operations. Deprecated.
DrawAlphaPixels
Warning: This property is deprecated. Deprecated components of DirectX 9.0 for Managed Code are considered obsolete. While these components are still supported in this release of DirectX 9.0 for Managed Code, they may be removed in the future. When writing new applications, you should avoid using these deprecated components. When modifying existing applications, you are strongly encouraged to remove any dependency on these components.
Supports alpha information in pixel format. The bit depth of alpha information in the pixel format can be 1, 2, 4, or 8. The alpha value becomes more opaque as the alpha value increases. Regardless of the depth of the alpha information, 0 is always the fully transparent value. Used for blit operations. Deprecated.
DrawAlphaPixelsNegative
Warning: This property is deprecated. Deprecated components of DirectX 9.0 for Managed Code are considered obsolete. While these components are still supported in this release of DirectX 9.0 for Managed Code, they may be removed in the future. When writing new applications, you should avoid using these deprecated components. When modifying existing applications, you are strongly encouraged to remove any dependency on these components.
Supports alpha information in pixel format. The bit depth of alpha information in the pixel format can be 1, 2, 4, or 8. The alpha value becomes more transparent as the alpha value increases. Regardless of the depth of the alpha information, 0 is always the fully opaque value. This flag can be used only if Alpha is set. Used for draw operations. Deprecated.
DrawAlphaSurfaces
Warning: This property is deprecated. Deprecated components of DirectX 9.0 for Managed Code are considered obsolete. While these components are still supported in this release of DirectX 9.0 for Managed Code, they may be removed in the future. When writing new applications, you should avoid using these deprecated components. When modifying existing applications, you are strongly encouraged to remove any dependency on these components.
Supports alpha-only surfaces. The bit depth of an alpha-only surface can be 1, 2, 4, or 8. The alpha value becomes more opaque as the alpha value increases. Regardless of the depth of the alpha information, 0 is always the fully transparent value. Used for blit operations. Deprecated.
DrawAlphaSurfacesNegative
Warning: This property is deprecated. Deprecated components of DirectX 9.0 for Managed Code are considered obsolete. While these components are still supported in this release of DirectX 9.0 for Managed Code, they may be removed in the future. When writing new applications, you should avoid using these deprecated components. When modifying existing applications, you are strongly encouraged to remove any dependency on these components.
Indicates that the alpha channel becomes more transparent as the alpha value increases. The depth of the alpha channel-data can be 1, 2, 4, or 8. Regardless of the depth of the alpha information, 0 is always the fully opaque value. This flag can be set only if Alpha has been set. Used for blit operations. Deprecated.
OverlayAlphaEdgeBlend
