- fileName
- A System.String containing the name of the image file to load.
- bitsPerPixel
Resulting image pixel depth. Valid values are:
Value Meaning 0 Keep the original file's pixel depth (Do not convert). 1 to 8 The specified bits per pixel in the resulting image. 12 12 bits per pixel in the resulting image. 16 16 bits per pixel in the resulting image. 24 24 bits per pixel in the resulting image. 32 32 bits per pixel in the resulting image. 48 48 bits per pixel in the resulting image. 64 64 bits per pixel in the resulting image.
- order
- The desired color order.
- channelIndex
- Index of the channel to load. This index is zero-based. Pass 0 to load the first channel, 1 to load the second channel, etc.
- channelInfo
- a CodecsPsdChannelInfo object to be updated with information about the loaded channel. Pass a null reference (Nothing in Visual Basic) for this parameter if channel information is not needed.

Use this method to load PSD files only.
This method works similarly to a normal RasterCodecs.Load or RasterCodecs.LoadAsync methods, except that it loads only a channel from a PSD file. It loads the channel specified in channel.
Before calling this method, you may need to get or set file information, such as the number of channels on the file. Refer to CodecsPsdImageInfo.
The number of channels in a file is indicated in CodecsPsdImageInfo.Channels. If this number is 0, the file does not contains any channels and this method should not be called.
Target Platforms: Silverlight, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
