This enumeration is used to describe the properties of an image source.
Syntax
enum SinkFlags { SinkFlagsScalable = ImageFlagsScalable, SinkFlagsHasAlpha = ImageFlagsHasAlpha, SinkFlagsPartiallyScalable = ImageFlagsPartiallyScalable, SinkFlagsTopDown = 0x00010000, SinkFlagsBottomUp = 0x00020000, SinkFlagsFullWidth = 0x00040000, SinkFlagsMultipass = 0x00080000, SinkFlagsComposite = 0x00100000, SinkFlagsWantProps = 0x00200000 }; |
Elements
- SinkFlagsScalable
-
Indicates that the source image is fully scaleable.
- SinkFlagsHasAlpha
-
Indicates that the source image contains transparency.
- SinkFlagsPartiallyScalable
-
Indicates that the source image is partially scaleable.
- SinkFlagsTopDown
-
Indicates that the source prefers to supply image data from top to bottom.
- SinkFlagsBottomUp
-
Indicates that the source prefers to supply image data from bottom to top.
- SinkFlagsFullWidth
-
Indicates that the source prefers to supply complete scan lines of image data.
- SinkFlagsMultipass
-
Indicates that the source prefers to supply image data by using multiple passes.
- SinkFlagsComposite
-
Indicates that the source prefers to composite over existing image data in the sink.
- SinkFlagsWantProps
-
Indicates that the source requires property information.
Remarks
The SinkFlags enumeration is divided into two categories, values from the lower byte and values from the upper byte:
- Values from the lower byte are shared with ImageFlags
enumeration and represent properties that are inherent to the
image.
- Values from the upper byte represent hints that an application
can use to work with the image as efficiently as possible.
