The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Sets the output channel color-profile file for the default category.

Namespace:   System.Drawing.Imaging
Assembly:  System.Drawing (in System.Drawing.dll)

Public Sub SetOutputChannelColorProfile (
	colorProfileFilename As String


Type: System.String

The path name of a color-profile file. If the color-profile file is in the %SystemRoot%\System32\Spool\Drivers\Color directory, this parameter can be the file name. Otherwise, this parameter must be the fully qualified path name.

You can use the SetOutputChannel and SetOutputChannelColorProfile methods to convert an image to a CMYK (cyan-magenta-yellow-black) color space and examine the intensities of one of the CMYK color channels. For example, suppose you write code that performs the following steps:

  1. Create an Image.

  2. Create an ImageAttributes object.

  3. Pass ColorChannelC to the SetOutputChannel method of the ImageAttributes object.

  4. Pass the path name of a color profile file to the SetOutputChannelColorProfile method of the ImageAttributes object.

  5. Pass the paths of the Image and ImageAttributes objects to the DrawImage method.

GDI+ will use the color-profile file to calculate the cyan component of each pixel in the image, and each pixel in the rendered image will be a shade of gray that indicates the intensity of its cyan channel.

An ImageAttributes object maintains color and grayscale settings for five adjustment categories: default, bitmap, brush, pen, and text. For example, you can specify an output channel color-profile file for the default category and a different output channel color-profile file for the bitmap category.

The default color-adjustment and grayscale-adjustment settings apply to all categories that do not have adjustment settings of their own. For example, if you never specify any adjustment settings for the bitmap category, the default settings apply to the bitmap category.
