PixelFormat Structure
Visual Studio 2010
Defines a pixel format for images and pixel-based surfaces.
Assembly: PresentationCore (in PresentationCore.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation
The PixelFormat type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | BitsPerPixel | Gets the number of bits-per-pixel (bpp) for this PixelFormat. |
![]() | Masks | Gets a collection of bit masks associated with the PixelFormat. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified object is equal to the current object. (Overrides ValueType.Equals(Object).) |
![]() | Equals(PixelFormat) | Determines whether the pixel format equals the given PixelFormat. |
![]() ![]() | Equals(PixelFormat, PixelFormat) | Determines whether the specified PixelFormat instances are considered equal. |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Creates a hash code from this pixel format's Masks value. (Overrides ValueType.GetHashCode.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Creates a string representation of this PixelFormat. (Overrides ValueType.ToString.) |
| Name | Description | |
|---|---|---|
![]() ![]() | Equality | Compares two PixelFormat instances for equality. |
![]() ![]() | Inequality | Compares two PixelFormat instances for inequality. |
The following example shows how to create a PixelFormat and find the value of its properties.
Public Function createPixelFormat() As PixelFormat
' Create a PixelFormat object.
Dim myPixelFormat As New PixelFormat()
' Make this PixelFormat a Gray32Float pixel format.
myPixelFormat = PixelFormats.Gray32Float
' Get the number of bits-per-pixel for this format. Because
' the format is "Gray32Float", the float value returned will be 32.
Dim bpp As Integer = myPixelFormat.BitsPerPixel
' Get the collection of masks associated with this format.
Dim myChannelMaskCollection As IList(Of PixelFormatChannelMask) = (myPixelFormat.Masks)
' Capture the mask info in a string.
Dim stringOfValues As String = " "
Dim myMask As PixelFormatChannelMask
For Each myMask In myChannelMaskCollection
Dim myBytesCollection As IList(Of Byte) = myMask.Mask
Dim myByte As Byte
For Each myByte In myBytesCollection
stringOfValues = stringOfValues + myByte.ToString()
Next myByte
Next myMask
' Return the PixelFormat which, for example, could be
' used to set the pixel format of a bitmap by using it to set
' the DestinationFormat of a FormatConvertedBitmap.
Return myPixelFormat
End Function 'createPixelFormat
End Class 'PixelFormatsExample
