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. |

Use this method to load PSD files only.
This method works similarly to a normal Load(String) or LoadAsync(String,LeadRect,Int32,CodecsLoadByteOrder,Int32,Int32,Object) methods, except that it loads only a channel from a PSD file. It loads the channel specified in channelIndex.
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.
