Exemples
L’exemple suivant montre comment utiliser la Masks propriété pour obtenir les masques de bits associés au format de pixel.
public PixelFormat createPixelFormat()
{
// Create a PixelFormat object.
PixelFormat myPixelFormat = 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.
int bpp = myPixelFormat.BitsPerPixel;
// Get the collection of masks associated with this format.
IList<PixelFormatChannelMask> myChannelMaskCollection = myPixelFormat.Masks;
// Capture the mask info in a string.
String stringOfValues = " ";
foreach (PixelFormatChannelMask myMask in myChannelMaskCollection)
{
IList<byte> myBytesCollection = myMask.Mask;
foreach (byte myByte in myBytesCollection)
{
stringOfValues = stringOfValues + myByte.ToString();
}
}
// 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;
}
